Afforestation, adding an artificial forest to a piece of land that has been barren of trees for a significant amount of time, has some seriously huge impacts on the environment. These effects can be seen as an increase in the soil organic matter, a decrease in compaction, and enhancement of porosity. Therefore, the soil can support more diverse microbes and fungal communities leading to better micro and macro nutrient transfers between plants. This …
Foliar Application Of Acetic Acid And Effectiveness Against Drought At Different Time Points In Soybean (Glycine Max) Development, Miranda Rudolph, Megan Taylor Phd.
Drought is arguably the most serious environmental factor affecting crop production today. A plants response to drought stress is extremely complex, affecting numerous metabolic pathways that are all interconnected in their responses. Due to this complex nature, scientists do not fully understand the implications of different treatments and how they affect these processes. Acetic acid has been shown to improve plant growth and resistance to drought stress, but exactly how it accomplishes this is also unknown. Soybeans (Glycine max) are one of the most important crops worldwide and can suffer significant yield loss due to drought stress. As climate change …
Weed-Induced Crop Yield Loss: A New Paradigm And New Challenges, 2023 USDA-ARS, Fargo, North Dakota
Weed-Induced Crop Yield Loss: A New Paradigm And New Challenges, David Horvath, Sharon A. Clay, Clarence J. Swanton, James V. Anderson, Wun S. Chao
Agronomy, Horticulture and Plant Science Faculty Publications
Direct competition for resources is generally considered the primary mechanism for weed-induced yield loss. A re-evaluation of physiological evidence suggests weeds initially impact crop growth and development through resource-independent interference. We suggest weed perception by crops induce a shift in crop development, before resources become limited, which ultimately reduce crop yield, even if weeds are subsequently removed. We present the mechanisms by which crops perceive and respond to weeds and discuss the technologies used to identify these mechanisms. These data lead to a fundamental paradigm shift in our understanding of how weeds reduce crop yield and suggest new research directions …
Boron Toxicity Induces Sulfate Transporters At Transcriptional Level In Arabidopsis Thaliana, Ceyhun Kayihan, Emre Aksoy, Su Naz Mutlu
Turkish Journal of Botany
Plants activate glutathione (GSH)-dependent detoxification pathways at biochemical and molecular levels under boron (B) toxicity. Sulfate uptake and transport are necessary for GSH biosynthesis in plants. Therefore, the transcriptional regulation of some sulfate transporters was determined in this study to clarify the importance of these transporters in leaf and root tissues of Arabidopsis thaliana under toxic B conditions. The expression level of SULTR1;3 was dramatically increased in leaf and root tissues under moderate and severe toxic B conditions, suggesting source-to-sink sulfate translocation under B toxicity. Stable expression levels of SULTR2;1, SULTR2;2, and low SULTR3;5 expression might restrict the sulfate movement …
Sorghum Wrky Transcription Factor Sbwrky45 Enhanced Seed Germination Under Drought Stress In Transgenic Arabidopsis, Elamin Baillo, Muhammad Sajid Hanif, Ping Xu, Zhengbin Zhang
Turkish Journal of Botany
The WRKY transcription factors (TFs) family is an important family of plant-specific TFs, playing vital roles in various abiotic and biotic stress responses. WRKY TFs are gaining considerable attention due to their significant roles in stress responses. However, their functions in sorghum (Sorghum bicolor) are lagging behind. In this study, a WRKY gene designated as SbWRKY45 was isolated and characterized from sorghum. SbWRKY45, belonging to Group IIa, consists of one intron and two exons and encodes 430 amino acids. SbWRKY45 is located in chromosome 4. The cis-element prediction analysis showed that the promoter region of SbWRKY45 has several abiotic …

Turkish Journal of Botany
Two new fossil species based on the study of wood remains and leaf imprints from the middle Eocene Çekerek Formation (central-northern part of Turkey) are assigned to the palm family Arecaceae. Standard thin sections from the two samples of fossil wood were investigated and identified as Palmoxylon sabaloides Greguss 1969, with close xylotomical affinities to the modern genus Sabal Adans. The leaf imprints are weakly costapalmate and correspond to the genus Sabal as well. Based on the short petiole extension (costa), the leaves resemble the fossil-species Sabal lamanonis (Brongn.) Heer, 1855. This fossil-species was abundant in Paleogene strata of western …
A New Annual Satureja (Lamiaceae) Species From Turkey With Molecular Evidence, And Lectotypification Of Two Species, Hayri̇ Duman, Tuncay Di̇rmenci̇, Taner Özcan
Turkish Journal of Botany
A new species, Satureja hasturkii, is described using morphological characters and molecular studies in this study. The new species is closely related to S. hortensis but differs from it by very lax thyrsoid inflorescence, longer pedicels, shorter calyx, upper and lower calyx teeth, and corolla. In order to support the morphological data, molecular studies are also done using nrITS and cptrnL-F gene regions. nrITS data gives better results in phylogenetic analysis. It is pointed out that the closest relatives of S. hasturkii are S. hortensis and S. laxiflora. The fact that having annual life forms of …
Seed Morphology Of Some Plantago (Plantaginaceae) Species In Iran And Its Systematic And Phylogenetic Implications, Saeed Mohsenzadeh, Masoud Sheidai, Fahimeh Koohdar
Turkish Journal of Botany
Plantago is a cosmopolitan genus with approximately 200 species and various infrageneric classifications have been reported. In this study, the seed morphologies of 19 species of Plantago from Iran were studied and documented in detail using scanning electron microscopy and light microscopy. The studied species were grouped by using statistical analyses such as a minimum spherical cluster method based on Euclidean distance, principal coordinate analysis, and multidimentional scaling. We have described four types based on the seed shape and states of the inner side of the studied seeds: convex- angular type, convex-elliptic type, flat-elliptic type, and concave-elliptic type. In this …

Attack Of The Clones: Elucidating The Role Of Clonality In The Invasion Success Of Carpobrotus Edulis, Eduardo Luis Cruz
Electronic Theses, Projects, and Dissertations
Transcriptomics is a modern technique in genomics that utilizes RNA sequences to get a snapshot of genetic expression. This is a powerful tool in non-model species lacking a reference genome. Thus, the application of comparative transcriptomics has the potential to help us elucidate the evolutionary mechanisms that facilitate species invasion. Carpobrotus edulis is a prolific and widespread invasive succulent plant belonging to the Aizoaceae family. A native to South Africa, this species has become a dominant invader of many Mediterranean coastal areas. In this study, we leveraged the use of RNAseq to investigate evolutionary changes among invasive populations. RNA-seq data …
Winter Dynamics Of Storm Water Management Ponds And Winter Tolerance In Three Aquatic Plant Species, 2023 Wilfrid Laurier University
Winter Dynamics Of Storm Water Management Ponds And Winter Tolerance In Three Aquatic Plant Species, Patrick Strzalkowski
Theses and Dissertations (Comprehensive)
The vast majority of the research into the performance of stormwater management ponds (SWMPs) has been performed in warm regions or during the warmer seasons in temperate regions. It is presumed that SWMPs are inactive in the winter as any potential stormwater is trapped in snow and ice. The main goal of this thesis was to test this presumption and to study the dynamics and performance of three SWMPs during the winter. Remote water level loggers were installed into the three SWMPs and daily grab samples from the influents and effluents were taken and analyzed for total phosphorus (TP), chloride, …

The Taxonomic Report of the International Lepidoptera Survey
Subsequent to the significant accomplishment of biological control of Opuntia weeds in Australia, the larvae of the cactus moth, Cactoblastis cactorum (native to parts of South America), were released in many countries for the biological control of native Opuntia species (Simmonds and Bennett, 1966). Inauspiciously, larvae were also released in the Caribbean, where the moth spread naturally and by the human support all over the region (García-Turudi et al., 1971). Its enhanced dissemination rate and the biological potential for invasiveness, suggests that the cactus moth is likely to become an invasive pest of Opuntia in the Southeast United States, Mexico, …
Is There An Economic Advantage To Planting Diverse Summer Annual Forage Mixtures?, 2022 USDA-ARS Pasture Systems and Watershed Management Research Unit
Is There An Economic Advantage To Planting Diverse Summer Annual Forage Mixtures?, Kelly Mercier, Chris Teutsch, Ray Smith, Kenny Burdine, Edwin Ritchey, Eric Vanzant
The Journal of Extension
This study examined economic implications of planting summer annual mixtures of grasses, legumes, and forbs at varying nitrogen rates. No differences in yield occurred between the three mixtures, indicating that mixtures with lowest seed cost will be most economical. Applying N resulted in yield increases of 12.26 lb DM per lb N applied. Although yield responses to N were positive, sensitivity analyses showed that applying N resulted in positive net returns only when hay prices were high and N prices were low. When utilization rates are accounted for, enterprise budgets determined grazing to be 18% cheaper to implement than haying.
Colored Sweet Bell And Tapered Pepper Cultivar Evaluation For High Tunnel Production In West-Central Indiana, 2022, Petrus Langenhoven, Lian Mahorith Duron Alvarado, Eduardo Jose Miranda Oviedo
Midwest Vegetable Trial Reports
Colored sweet bell-shaped and tapered peppers are a staple at the farmers' market. Many small and medium-sized farming operations in Indiana grow this summer crop. High tunnels allow growers to protect their crops and extend their growing season. Sweet peppers, in particular, benefit from the unique growing environment created by the high tunnel. Planting of peppers can start at least 2-4 weeks earlier in the spring, and production can continue into the fall until the first hard freeze. Pepper variety performance data for Indiana is not readily available. We are working hard to change that. Currently, we have evaluated twenty-five …
