Selection On Crop-Derived Traits And Qtl In Sunflower (Helianthus Annuus) Crop-Wild Hybrids Under Water Stress, Birkin R. Owart, Jonathan Corbi, John M. Burke, Jennifer M. Dechaine

All Faculty Scholarship for the College of the Sciences

Locally relevant conditions, such as water stress in irrigated agricultural regions, should be considered when assessing the risk of crop allele introgression into wild populations following hybridization. Although research in cultivars has suggested that domestication traits may reduce fecundity under water stress as compared to wild-like phenotypes, this has not been investigated in crop-wild hybrids. In this study, we examine phenotypic selection acting on, as well as the genetic architecture of vegetative, reproductive, and physiological characteristics in an experimental population of sunflower crop-wild hybrids grown under wild-like low water conditions. Crop-derived petiole length and head diameter were favored in low …

Functional Genomics Of Maize Endosperm Maturation And Protein Quality, Lingling Yuan

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Maize is one of the most important cereal crops and widely cultivated throughout the world. The study on maize kernel development including protein quality improvement is essential for removing dietary protein deficiency because of the lack of essential amino acids, especially lysine and tryptophan, in maize kernel. Quality Protein Maize (QPM) is a hard kernel variant of the high-lysine mutant, opaque-2. We created opaque QPM variants to identify opaque-2 modifier genes and to investigate deletion mutagenesis combined with Illumina sequencing as a maize functional genomics tool. A K0326Y-QPM deletion mutant, line 107, was null for the 27- and 50-kD …

Qtl Architecture Of Reproductive Fitness Characters In Brassica Rapa, Jennifer M. Dechaine, Marcus T. Brock, Cynthia Weinig

All Faculty Scholarship for the College of the Sciences

Background

Reproductive output is critical to both agronomists seeking to increase seed yield and to evolutionary biologists interested in understanding natural selection. We examine the genetic architecture of diverse reproductive fitness traits in recombinant inbred lines (RILs) developed from a crop (seed oil) × wild-like (rapid cycling) genotype of Brassica rapa in field and greenhouse environments.

Results

Several fitness traits showed strong correlations and QTL-colocalization across environments (days to bolting, fruit length and seed color). Total fruit number was uncorrelated across environments and most QTL affecting this trait were correspondingly environment-specific. Most fitness components were positively correlated, consistent with life-history …

Bradyrhizobium sp. strain WSM1417 is an aerobic, motile, Gram-negative, non-spore-forming rod that was isolated from an effective nitrogen (N2) fixing root nodule of Lupinus sp. collected in Papudo, Chile, in 1995. However, this microsymbiont is a poorly effective N2 fixer with the legume host Lupinus angustifolius L.; a lupin species of considerable economic importance in both Chile and Australia. The symbiosis formed with L. angustifolius produces less than half of the dry matter achieved by the symbioses with commercial inoculant strains such as Bradyrhizobium sp. strain WSM471. Therefore, WSM1417 is an important candidate strain with which to investigate the genetics …

Crop yields at summit positions of rolling landscapes often are lower than backslope yields. The differences in plant response may be the result of many different factors. We examined corn (Zea mays L.) plant productivity, gene expression, soil water, and nutrient availability in two landscape positions located in historically high (backslope) and moderate (summit and shoulder) yielding zones to gain insight into plant response differences. Growth characteristics, gene expression, and soil parameters (water and N and P content) were determined at the V12 growth stage of corn. At tassel, plant biomass, N content, ¹³C isotope discrimination (Δ), and …

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Soybean was introduced in the U.S. in the 1800s, and it has been proven to have several health benefits. New cultivars of soybeans with varying hull colors have been developed using plantbreeding technology. Canning is one of the effective processing methods to extend the shelf life of products. However, very little information is available on canned soybeans. This research studied the composition of 12 soybean cultivars including two cultivars with brown seed coat (R08-4014 and R09-349), three cultivars with black seed coat (R07-1927, R07-10396, and R09-345), and seven regular cultivars with yellow seed coat (R05-1772, R05-4969, R07-2001, R08-4005, R08- 4006, …

Evaluation Of Cover Crops In High Tunnel Vegetable Rotation, Tyler A. Patrick, Neal Mays, Jason Mcafee, Curt R. Rom

Organic vegetable production within high tunnels allows for an extended growing season, crop protection, and environmental control. The USDA National Organic Program (NOP) standards mandate evidence that the soil has been maintained and improved over the course of production. Previous studies have indicated the potential of cover crops for reducing competitive vegetation, and improving soil quality, thus resulting in greater plant growth, nutrient uptake, and yield. However, there has been limited work in the confines of high tunnels as part of a tunnel-system rotation. Ten nitrogen-fixing and ten non-legume cover crops were established under a high tunnel and evaluated for …

Characterization Of Seediness Attributes Of Blackberry Genotypes, Bethany Sebesta, John R. Clark, Renee T. Threlfall, Luke R. Howard

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Fresh market blackberries can feel “seedy” when consumed. This “seediness” is associated with the presence of pyrenes which are comprised of a single seed enclosed in an endocarp. Small pyrene size  (<3 mg) is preferred in both fresh-market and processed blackberry products. Yet, the proportion of pyrene weight to total berry weight can be more important than pyrene size. The objective of this study was to determine and compare descriptive sensory analysis and pyrene characteristics of blackberry genotypes from the University of Arkansas System Division of Agriculture blackberry breeding program. Panelists were trained according to Spectrum® methods and evaluated 20 genotypes for overall seediness. Pyrene characteristics, including weight and dimension, were measured for 22 genotypes. Seven of the 22 genotypes had an individual pyrene weight of 3 mg or less. Pyrene weight to berry weight ratio ranged from 2.7% (‘Tupy’) to 5.4% (‘Prime-Ark® 45’). ‘Tupy’ had low individual pyrene weights and a low ratio, which are most likely factors that contribute to its widespread acceptance by consumers. Pyrene weight to berry weight ratio was positively correlated to descriptive overall seediness (r = 0.70) but not to number of pyrenes/berry. Therefore, finding a desirable pyrene weight to berry weight ratio is integral to decreasing perceived seediness in the development of new blackberry cultivars.

Sorghum Transformation: Overview And Utility, Tejinder Kumar, Arlene Howe, Shirley Sato, Ismail M. Dweikat, Tom E. Clemente

Department of Agronomy and Horticulture: Faculty Publications

Over the past decade genomics resources available for sorghum have rapidly expanded (Paterson Int J Plant Genomics 2008:6, 2008), these resources, coupled with the recent completion of the genome sequence which is relatively small in size (730 Mb) (Paterson et al. Nature 457:551–556, 2009) makes sorghum a rather attractive species to study. Moreover, the USDA germplasm system maintains 42,614 accessions, of which more than 800 exotic landraces have been converted to day length-insensitive lines to facilitate their use in breeding programs. In addition, a set of EMS mutation stocks developed by the USDA Plant Stress and Germplasm Development Unit in …
