Long-term climate change and periodic environmental extremes threaten food and fuel
security 1 and global crop productivity 2 , 3 – 4 . Although molecular and adaptive breeding …

Background Plants can transmit somatic mutations and epimutations to offspring, which in
turn can affect fitness. Knowledge of the rate at which these variations arise is necessary to …

Camelina [Camelina sativa (L.) Crantz] is an oilseed crop in the Brassicaceae family that is
currently being developed as a source of bioenergy and healthy fatty acids. To facilitate …

Connecting broad‐scale patterns of genetic variation and population structure to genetic
diversity on a landscape is a key step towards understanding historical processes of migration …

Flowering time is a major determinant of biomass yield in switchgrass (Panicum virgatum), a
perennial bioenergy crop, because later flowering allows for an extended period of …

Geographic patterns of genetic variation are shaped by multiple evolutionary processes,
including genetic drift, migration and natural selection. Switchgrass ( P anicum virgatum L.) has …

Polyploidy results from whole-genome duplication and is a unique form of heritable variation
with pronounced evolutionary implications. Different ploidy levels, or cytotypes, can exist …

Geographic patterns of within-species genomic diversity are shaped by evolutionary processes,
life history and historical and contemporary factors. New genomic approaches can be …

The perennial grass species that are being developed as biomass feedstock crops harbor
extensive genotypic diversity, but the effects of this diversity on biomass production are not …

Depression and anxiety are the most common psychiatric disorders in end-stage renal disease
(ESRD) patients treated with hemodialysis (HD) and may correlate with lower quality of …
