Silvopastoral system (SPS) are characterized by a combination of trees, pasture and herbivores animals, in the same physical area, in order to obtain diversified products. A promising legume tree that has been studied and used in SPS in tropical areas is gliricidia [Gliricidia sepium (Jacq.) Steud]. Advantages of gliricidia use in SPS include N inputs via biological fixation, improvement of soil properties, nutrient cycling and also a source of feed to grazing animals (Cubillos-Hinojosa et al., 2011). Gliricidia has high crude protein concentration in its leaves, which complements the usual N-poor diet of ruminants grazing warm-season grasses. The …

IGC Proceedings (1997-2023)
Nitrogen (N) is the most important nutrient for growth and development of pasture, giving the plant a faster growth rate and greater production (Roma et al. 2012). Despite proven effectiveness, there is restriction on its use by farmers due to high cost. On the other hand, the legume Estilozantes Campo Grande (Stylosanthes spp. (80% S. capitata + 20% S. macrocephala), capable of fixing nitrogen atmospheric has become a promising plant, as shown by the work of Ribeiro et al. (2011). However, there is still a lack of information about its use in association with grasses for animal …

Cover crops (CC) in corn (Zea mays L.) and soybean [Glycine max (L.) Merr.] rotations may prevent N loss and provide other ecosystem services but CC productivity in the western Corn Belt is limited by the short growing season. Our objective was to assess CC treatment and planting practice effects on CC biomass, spring soil nitrate concentrations, and soybean yield at two rainfed sites in eastern and one irrigated site in south-central Nebraska over 4 years. Cover crop treatments (cereal rye [Secale cereale L.] [RYE] and a mix of rye, legume, and brassica species [MIX]) were planted …
Introducing Faba Bean As A New Multi-Purpose Crop For Northeast U.S.A., Fatemeh Etemadi
Introducing Faba Bean As A New Multi-Purpose Crop For Northeast U.S.A., Fatemeh Etemadi
Doctoral Dissertations
Faba bean is a multi-benefit cool-season grain legume that can be integrated into cropping systems of a shorter-growing season regions such as New England. A comprehensive research study was conducted to explore the ecological, nutritional, medicinal, and financial benefits of faba bean as a new multi-purpose crop for Northeast U.S.A. It was revealed that the faba bean genotypes exhibited dramatic variations in thermal units required to reach various phenological stages. Using phenology, morphology and physiological growth pattern of six faba bean varieties showed that larger seeds and later maturity did not necessarily produced higher yield. Aquadulce, the earliest maturity with …

Biology Faculty Publications
The arbuscular mycorrhizal (AM) symbiosis between terrestrial plants and AM fungi is regulated by plant hormones. For most of these, a role has been clearly assigned in this mutualistic interaction; however, there are still contradictory reports for cytokinin (CK). Here, pea plants, the wild type (WT) cv. Sparkle and its mutant E151 (Pssym15), were inoculated with the AM fungus Rhizophagus irregularis. E151 has previously been characterized as possessing high CK levels in non-mycorrhizal (myc-) roots and exhibiting high number of fungal structures in mycorrhizal (myc+) roots. Myc- and myc+ plants were …

Genetic And Molecular Mechanisms Underlying Symbiotic Specificity In Legume-Rhizobium Interactions, Qi Wang, Jinge Liu, Hongyan Zhu
Plant and Soil Sciences Faculty Publications
Legumes are able to form a symbiotic relationship with nitrogen-fixing soil bacteria called rhizobia. The result of this symbiosis is to form nodules on the plant root, within which the bacteria can convert atmospheric nitrogen into ammonia that can be used by the plant. Establishment of a successful symbiosis requires the two symbiotic partners to be compatible with each other throughout the process of symbiotic development. However, incompatibility frequently occurs, such that a bacterial strain is unable to nodulate a particular host plant or forms nodules that are incapable of fixing nitrogen. Genetic and molecular mechanisms that regulate symbiotic specificity …
Transcriptional Reprogramming Of Legume Genomes: Perspective And Challenges Associated With Single-Cell And Single Cell-Type Approaches During Nodule Development, Marc Libault
Department of Agronomy and Horticulture: Faculty Publications
Transcriptomic approaches revealed thousands of genes differentially or specifically expressed during nodulation, a biological process resulting from the symbiosis between leguminous plant roots and rhizobia, atmospheric nitrogen-fixing symbiotic bacteria. Ultimately, nodulation will lead to the development of a new root organ, the nodule. Through functional genomic studies, plant transcriptomes have been used by scientists to reveal plant genes potentially controlling nodulation. However, it is important to acknowledge that the physiology, transcriptomic programs, and biochemical properties of the plant cells involved in nodulation are continuously regulated. They also differ between the different cell-types composing the nodules. To generate a more accurate …

Genetic Basis Of Biosynthesis And Cytotoxic Activity Of Medicago Truncatula Triterpene Saponins, Brynn Kathleen Lawrence
Genetic Basis Of Biosynthesis And Cytotoxic Activity Of Medicago Truncatula Triterpene Saponins, Brynn Kathleen Lawrence
Graduate Theses and Dissertations
Saponins are a large family of specialized metabolites produced in many plants. They can have negative effects on a number of plant pests and are thought to play a role in plant defense. With current and possible future uses in industry and agriculture, saponins have also been shown to be hypocholesterolemic, hypoglycemic, immunostimulatory, antioxidative, anti-inflammatory, and cytotoxic. In spite of their usefulness, our understanding of the genetic basis for saponin biosynthesis is still incomplete. We generated recombinant populations with parents from genetically distinct accessions of Medicago truncatula, with either high or low accumulation and varying profiles of saponins. Primers for …

Nitrogen is one of the most essential plant nutrients and one of the major factors limiting crop productivity. Having the goal to perform a more sustainable agriculture, there is a need to maximize biological nitrogen fixation, a feature of legumes. To enhance our understanding of the molecular mechanisms controlling the interaction between legumes and rhizobia, the symbiotic partner fixing and assimilating the atmospheric nitrogen for the plant, researchers took advantage of genetic and genomic resources developed across different legume models (e.g., Medicago truncatula, Lotus japonicus, Glycine max, and Phaseolus vulgaris) to identify key regulatory protein coding genes of the nodulation …
The Endophytes Of Pediomelum Esculentum: A Unique Case In Legume Evolution, Tyrel Ryan Deutscher
The Endophytes Of Pediomelum Esculentum: A Unique Case In Legume Evolution, Tyrel Ryan Deutscher
Electronic Theses and Dissertations
Pediomelum esculentum (commonly prairie turnip) is a perennial legume of the Great Plains, consisting of a deep taproot and large edible tuber, and has served as a nutritious staple in Native American diets. The tuber is capable of storing up to 20 percent protein by weight. P. esculentum is a legume, but not a prominent nodule former; instead, it grows in nitrogen-limited soils and produces large amounts of protein. This suggests the involvement of biological nitrogen fixation. We have investigated the presence of diazotrophic endophytes in P. esculentum. Bacteria were isolated from wild plants on nitrogen free media, identified …
Factors Constraining The Reproductive Output Of Baptisia Alba Macrophylla, Ashley Morgan Hembrough
Factors Constraining The Reproductive Output Of Baptisia Alba Macrophylla, Ashley Morgan Hembrough
Theses and Dissertations
Baptisia alba macrophylla, a native, herbaceous perennial legume, produces inflorescences with a large number of flowers, yet matures relatively few fruits. We hypothesized that the number of seeds matured by B. alba macrophylla is maximized based on resource availability at each stage of development, but this optimal number is further compromised by extrinsic factors including pollen limitation and pre-dispersal seed predation by the weevils Apion rostrum and Tychius sordidus. To test this hypothesis, we conducted a field experiment at two sites: (i) the John English Prairie, located in Hudson, IL, and also (ii) the Sugar Grove Nature Center and Funks …

Biology Faculty Publications
In legumes, the formation of rhizobial and mycorrhizal root symbioses is a highly regulated process which requires close communication between plant and microorganism. Plant mutants that have difficulties establishing symbioses are valuable tools for unravelling the mechanisms by which these symbioses are formed and regulated. Here E151, a mutant of Pisum sativum cv. Sparkle, was examined to characterize its root growth and symbiotic defects. The symbioses in terms of colonization intensity, functionality of micro-symbionts, and organ dominance were compared between the mutant and wild type. The endogenous cytokinin (CK) and abscisic acid (ABA) levels and the effect of the exogenous …

Plant and Soil Sciences Faculty Publications
BACKGROUND: Leguminous plants are able to form a root nodule symbiosis with nitrogen-fixing soil bacteria called rhizobia. This symbiotic association shows a high level of specificity. Beyond the specificity for the legume family, individual legume species/genotypes can only interact with certain restricted group of bacterial species or strains. Specificity in this system is regulated by complex signal exchange between the two symbiotic partners and thus multiple genetic mechanisms could be involved in the recognition process. Knowledge of the molecular mechanisms controlling symbiotic specificity could enable genetic improvement of legume nitrogen fixation, and may also reveal the possible mechanisms that restrict …

Plant And Animal Performance In Tall Fescue And Tall Fescue/Legume Pastures, Troy J. Bingham
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Tall fescue is the one of most common grasses in irrigated pastures throughout the Intermountain West. Two limitations of tall fescue are a decrease in productivity during hot summer months and the need for supplemental nitrogen (N). The objective of this research was to compare tall fescue-alfalfa (TF+ALF), tall fescue-birdsfoot trefoil (TF+BFT), tall fescue-nitrogen fertilizer (TF+N), and tall fescue without nitrogen fertilizer (TF-N) on forage yield, nutritional quality, and livestock performance. Research plots were established at the Utah State University Pasture Research Facility in Lewiston, UT in 2010 and grazed in 2012 and 2013. Treatments were arranged in a randomized …
Leaf Gas Films Delay Salt Entry And Enhance Underwater Photosynthesis And Internal Aeration Of Melilotus Siculus Submerged In Saline Water, Natasha Lea Teakle, Timothy David Colmer, Ole Pedersen
Leaf Gas Films Delay Salt Entry And Enhance Underwater Photosynthesis And Internal Aeration Of Melilotus Siculus Submerged In Saline Water, Natasha Lea Teakle, Timothy David Colmer, Ole Pedersen
Research outputs 2014 to 2021
A combination of flooding and salinity is detrimental to most plants. We studied tolerance of complete submergence in saline water for Melilotus siculus, an annual legume with superhydrophobic leaf surfaces that retain gas films when under water. M.siculus survived complete submergence of 1 week at low salinity (up to 50molm-3 NaCl), but did not recover following de-submergence from 100molm-3 NaCl. The leaf gas films protected against direct salt ingress into the leaves when submerged in saline water, enabling underwater photosynthesis even after 3d of complete submergence. By contrast, leaves with the gas films experimentally removed suffered from substantial Na+ and …
Redbud Seedpods Hold Surprises, W. John Hayden
Redbud Seedpods Hold Surprises, W. John Hayden
Biology Faculty Publications
As fall advances across the Old Dominion, canopies of redbud, the 2013 VNPS Wildflower of the Year, transform themselves from green to gold, revealing seed pods also changing color from pale green to dark chocolaty brown. These seedpods, which may be retained on the tree into winter, are typical legume fruits, the product of the flower’s simple pistil, each containing several seeds. Unlike most legumes, however, redbud seed pods seem disinclined to open and release individual seeds for dispersal. Redbud fruits tend to disperse intact. Once on the ground, the inevitable action of weather and microbes gradually degrades the pod, …
A Legume Biofortification Quandary: Variability And Genetic Control Of Seed Coat Micronutrient Accumulation In Common Beans, Matthew W. Blair, Paulo Izquierdo, Carolina Astudillo, Michael A. Grusak
A Legume Biofortification Quandary: Variability And Genetic Control Of Seed Coat Micronutrient Accumulation In Common Beans, Matthew W. Blair, Paulo Izquierdo, Carolina Astudillo, Michael A. Grusak
Agricultural and Environmental Sciences Faculty Research
Common beans (Phaseolus vulgaris L.), like many legumes, are rich in iron, zinc, and certain other microelements that are generally found to be in low concentrations in cereals, other seed crops, and root or tubers and therefore are good candidates for biofortification. But a quandary exists in common bean biofortification: namely that the distribution of iron has been found to be variable between the principal parts of seed; namely the cotyledonary tissue, embryo axis and seed coat. The seed coat represents ten or more percent of the seed weight and must be considered specifically as it accumulates much of …
The Effects Of Arbuscular Mycorrhizal Fungi On Four Legume Hosts In South Florida Pine Rockland Soils, Klara Scharnagl
The Effects Of Arbuscular Mycorrhizal Fungi On Four Legume Hosts In South Florida Pine Rockland Soils, Klara Scharnagl
FIU Electronic Theses and Dissertations
This study addressed the effects of salinity and pot size on the interaction between leguminous plant hosts and arbuscular mycorrhizal fungi in four pine rockland soils using a shade house trap-plant experiment. Little is known about the belowground diversity of pine rocklands and the interactions between aboveground and belowground biota – an increased understanding of these interactions could lead to improved land management decisions, conservation and restoration efforts. Following twelve weeks of growth, plants were measured for root and shoot dry biomass and percent colonization by arbuscular mycorrhizal fungi. Overall, arbuscular mycorrhizal fungi had positive fitness effects on the four …
Redbuds Similar Around The World, W. John Hayden
Redbuds Similar Around The World, W. John Hayden
Biology Faculty Publications
Like music, one of the hallmarks of biodiversity is theme and variation. Redbuds—species of the genus Cercis— from around the world illustrate this analogy well. Because all redbud species conform to a certain morphological theme, anyone familiar with one particular species of redbud should be able to recognize without hesitation any other redbud species as a member of the genus Cercis. In brief, the redbud theme consists of broad, basally-lobed, leaves with pulvinar petiole thickenings, and pea-like red-purple (rarely white) flowers that may arise on small twigs or main trunks. In fact, these plants are so distinctive, it would …

Although legumes constitute one of the largest families of flowering plants in the world, and despite 25 years of celebrating Virginia’s wildflowers, redbud (Cercis canadensis) is the first legume to be recognized as a VNPS Wildflower of the Year. This article addresses the relationships of Cercis with the rest of the legumes (family Fabaceae, or Leguminosae in older literature).
Sunergos1, A Lotus Japonicus Gene Required For Proper Accommodation Of Rhizobial Infection, Hwi Joong Yoon
Sunergos1, A Lotus Japonicus Gene Required For Proper Accommodation Of Rhizobial Infection, Hwi Joong Yoon
Electronic Thesis and Dissertation Repository
Here, I characterize a symbiotic mutant of Lotus japonicus, called sunergos1 (suner1), which originated from a har1-1 suppressor screen. I have shown that suner1 supports epidermal infection by rhizobia and initiates nodule primordia organogenesis as in wild-type. However, the infection process is temporarily stalled, such that infection threads fail to ramify within the root cortex and timely release of bacteria inside the nodule primordia cells does not occur. This symbiotic defect is ephemeral and with additional time, functional nodules are formed. Using a combined approach involving map-based cloning and next-generation sequencing, I have shown that the suner1 …

Seedling Root Morphology Of Six Alfalfa Populations, Brianna J. Gaughan
Seedling Root Morphology Of Six Alfalfa Populations, Brianna J. Gaughan
The Journal of Undergraduate Research
Seedling root morphology plays a crucial role in seedling survival and stand establishment. Naturalized yellow-flowered alfalfa (YFA) (Medicago sativa subsp. falcata) has demonstrated adaptation to semiarid conditions of the Northern Great Plains and tolerance to grazing. Seedling stage root morphology is poorly defined. Our objective was to compare morphological traits of seedling roots for six alfalfa populations. Six entries were evaluated: one M. sativa population as a control, two M. falcata entries, with reported “spreading characteristics” and three naturalized YFA populations. Uniform seeds of each entry were scarified with 320 grade sand paper and inoculated with rhizobium before planting. A …
Shoot Morphology Of Eleven Alfalfa Populations, Jessica A. Schmuck
Shoot Morphology Of Eleven Alfalfa Populations, Jessica A. Schmuck
The Journal of Undergraduate Research
Alfalfa (Medicago sativa L.) is a major component of feed for dairy and beef cattle and one of the most productive forage species in North America. Alfalfa has been planted on millions of acres. More than 100 varieties have been developed in North America over the past 100 years. However, historically, alfalfa persistence under grazing in semiarid rangeland has generally been poor. Recently, it was discovered that naturally-selected populations of predominantly yellow-flowered alfalfa have been proven to be adapted to rangelands of western South Dakota and adjacent areas. A study was initiated in May 2006 to evaluate persistence and vigor …

Comparative Studies On The Competence Of Axillary Shoot Regeneration On Unsliced And Longitudinally Sliced Cotyledon Nodes Of Vigna Unguiculata, Muhammad Aasim, Sancar Fati̇h Özcan, Khalid Mahmood Khawar, Sebahatti̇n Özcan
Turkish Journal of Botany
Vigna unguiculata is an important food legume crop in the semiarid tropics. It suffers from a host of agricultural constraints including damage due to diseases and pests. Judicious application of biotechnological methods can lead to considerable improvement in this important crop. Shoot regeneration from unsliced and longitudinally sliced cotyledon node explants obtained from 3-day-old to 5-day-old seedlings grown in vitro was achieved on Murashige and Skoog (MS) medium containing 1.11, 2.22, 3.33, and 4.44 \muM benzylaminopurine (BA) supplemented with 1.0 mg/L polyvinylpyrrolidone and 500 mg/L bacteriostatic Augmentin. Callus induction was recorded in all culture media on both explants. The shoot …
