Hierarchical classification of switchgrass genotypes using SSR and chloroplast sequences: ecotypes, ploidies, gene pools, and cultivars
TLDR
This classification system is the first step toward developing switchgrass complementary gene pools that can be expected to provide a significant heterotic increase in biomass yield.
Post-glacial evolution of Panicum virgatum: centers of diversity and gene pools revealed by SSR markers and cpDNA sequences
TLDR
It is estimated that both upland-lowland divergence and 4x-to-8x polyploidization within switchgrass began approximately 1.5 M ybp and that subsequent ice age cycles have resulted in gene flow between ecotype lineages and between ploidy levels, resulting in “hot spots” of genetic diversity in the southeastern USA and along the Atlantic Seaboard.
Chelating Activity of Advanced Glycation End-product Inhibitors*
TLDR
Inhibition of AGE formation results primarily from the chelating or antioxidant activity of the AGE inhibitors, rather than their carbonyl trapping activity.
Natural Hybrids and Gene Flow between Upland and Lowland Switchgrass
TLDR
The central and eastern Gulf Coast glacial refuge is proposed as the primary center of origin and diversity for switchgrass, with the western Gulf Coast as the secondary center oforigin and diversity.
Biology, Rearing, and Preliminary Evaluation of Host Range of Two Potential Biological Control Agents for Mile-a-Minute Weed, Polygonum perfoliatum L.
TLDR
Basic biology and rearing methods were determined for Timandra griseata Peterson and Homorosoma chinensis Wagner, two potential biological control agents of mile-a-minute weed and their ability to feed and develop on crop plants in the family Polygonaceae.
Some observations from the excavation of honey mesquite root systems.
TLDR
Results from the excavations provide evidence in support of honey mesquite’s classification as P facultative pbreatopbyte.
Short Duration Grazing at the Texas Experimental Ranch: Weight Gains of Growing Heifers
TLDR
It is tentatively concluded from the results of this and previous studies that a properly managed SDG system may satisfactorily support livestock at rates of stocking appreciably greater than that normally expected from conventional grazing schemes.
Impact of Foot Traffic from Military Training on Soil and Vegetation Properties
TLDR
Training use appears to adversely affect bulk density, infiltration, total aboveground biomass, litter, and erosion and without implementation of restoration practices, further site degradation is likely.
