“Primitive” Wood Characters Are Adaptive: Examples From Paracryphiaceae,
2018
Santa Barbara Botanic Garden, Santa Barbara, California
“Primitive” Wood Characters Are Adaptive: Examples From Paracryphiaceae, Sherwin Carlquist
Aliso: A Journal of Systematic and Floristic Botany
Why plants rich in plesiomorphic (“primitive”) features are alive today is a question that receives little comment. Apomorphies in angiosperms are often interpreted as valuable adaptations. However, both apomorphies and plesiomorphies can be keyed to ecological and physiological features. If a particular habitat remains little modified for long periods of geological time, plesiomorphic features should theoretically persist. The Bailey-Frost-Kribs correlations (usually between tracheary element length and character states in other wood features), deemed useful in their day, did not include adaptation to ecology, nor did they have the advantages that molecular-based phylogenies bring to us today. Montane cloud forests or …

The Vascular Flora Of The Red River Gorge In Powell, Menifee, And Wolfe Counties Kentucky, Thomas Steele Mcfadden
Online Theses and Dissertations
The Red River Gorge (RRG) is a 26,283 ha natural area within Menifee, Powell, and Wolfe counties of Kentucky. This area is in the Cumberland Plateau Physiographic Section which is a southern subsection of the Appalachian Plateau Physiographic Province. It is a mecca of outdoor recreation, hosting thousands of visitors each year, while also being home to a unique flora worthy of continued protection. A vascular flora was conducted between the fall of 2016 and the summer of 2018. Additional vouchers donated by Dr. Ross C. Clark and the Stanton Ranger District office, as well as vouchers deposited at regional …

Finding Aids
Louise Helen Coburn was born in Skowhegan, Maine on September 1, 1856, daughter of Stephen Coburn and Helen Sophia Miller. Coburn was Colby's second female graduate (after Mary Low Carver) in 1877, and graduated with Phi Beta Kappa honors. She also later received an honorary Litt. D. degree from Colby in 1914. Coburn's family was deeply tied to Colby College. Her father Stephen graduated in 1839, and the Coburn family was critical to Colby's early development as benefactors. Coburn was a co-founder, along with Mary Low Carver and others, of the Sigma Kappa Sorority. Coburn also later attended the Harvard …

Optimising The Identification Of Causal Variants Across Varying Genetic Architectures In Crops, Chenyong Miao, Jinliang Yang, James C. Schnable
Department of Agronomy and Horticulture: Faculty Publications
Association studies use statistical links between genetic markers and the phenotype variation across many individuals to identify genes controlling variation in the target phenotype. However, this approach, particularly conducted on a genome-wide scale (GWAS), has limited power to identify the genes responsible for variation in traits controlled by complex genetic architectures. In this study, we employ real-world genotype datasets from four crop species with distinct minor allele frequency distributions, population structures and linkage disequilibrium patterns. We demonstrate that different GWAS statistical approaches provide favourable trade-offs between power and accuracy for traits controlled by different types of genetic architectures. FarmCPU provides …

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 …

First Case Of Glufosinate-Resistant Rigid Ryegrass (Lolium Rigidum Gaud.) In Greece, Ilias S. Travlos, Nikolina Cheimona, Rafael De Prado, Amit J. Jhala, Demosthenis Chachalis, Eleni Tani
Department of Agronomy and Horticulture: Faculty Publications
Repeated applications of the same herbicide(s), which are characterized by the same mode of action, increase selection pressure, which in turn favours the evolution of herbicide-resistant weeds. Glufosinate is a broad-spectrum non-selective herbicide being used for weed control for many years around the world. Rigid ryegrass (Lolium rigidum Gaud.) is an economically important grass weed in Greece. Recent complaints by growers about control failure of rigid ryegrass with glufosinate require further investigation and have been the basis of this study. The objectives of this study were to confirm the existence of glufosinate-resistant L. rigidum in Greece and evaluate the …

Empowerment And Tech Adoption: Introducing The Treadle Pump Triggers Farmers’ Innovation In Eastern Ethiopia, Shimelis Beyene, Teshome H. Regassa, Belaineh Legesse, Martha Mamo, Tsegaye Tadesse
Department of Agronomy and Horticulture: Faculty Publications
In 2013, thirty-eight treadle pumps (TPs) were installed as low-cost technology introduction for small-scale irrigation in eastern Ethiopia. This pilot project also trained six farmers on tube well excavation, as well as the installation and maintenance of pumps. In June 2015, researchers visited nine of the thirty-eight TP villages and found only two TPs functioning as originally installed. The rest were replaced with a new technology developed by the trained farmers. Farmers, empowered by training, gained more control in developing technology options tailored to local needs and conditions of their communities. Adopters of the new technology stated that the limited …

Ensuring an adequate food supply in systems that protect environmental quality and conserve natural resources requires productive and resource-efficient cropping systems on existing farmland.Meeting this challenge will be difficult without a robust spatial framework that facilitates rapid evaluation and scaling-out of currently available and emerging technologies. Here we develop a global spatial framework to delineate ‘technology extrapolation domains’ based on key climate and soil factors that govern crop yields and yield stability in rainfed crop production. The proposed framework adequately represents the spatial pattern of crop yields and stability when evaluated over the data-rich US Corn Belt. It also facilitates …

Department of Agronomy and Horticulture: Faculty Publications
A decline in land and water productivity, increase in the cost of cultivation, and labor-intensive practices are affecting the cereal-based farming system in Nepal, particularly in the Indo-Gangetic Plains (IGP). Conservation agriculture (CA) practices have been found to be the climate-, energy-, and labor-smart and sustainable agricultural production technologies. Sustainable and Resilient Farming System Intensification (SRFSI) has been working since 2014 in response to the sustainability of the cereal-based (rice–wheat and rice–maize) farming in Sunsari and Dhanusha districts of Nepal. This study was conducted to assess the adoption and scaling up of CA in addition to input usage, production, net …

Department of Agronomy and Horticulture: Faculty Publications
Environmental factors like drought impact the quality of biomass entering a bioconversion process. Drought often reduces the sugar content in lignocellulosic biomass, which could have economic impacts, particularly when compounded with losses in dry biomass yield; however, the effects on conversion efficiency are not completely understood. This study investigated how drought may impact biomass composition and sugar yields from dilute-acid pretreatment and enzymatic hydrolysis of Miscanthus, a tall fescue mixture, and switchgrass from Nebraska, Missouri, and Oklahoma, respectively, grown as part of Regional Feedstock Partnership field trials. Samples were grown and harvested in 2010 during non-drought conditions and in …
