Tepary bean (Phaseolus acutifolis A. Gray), native to the Sonoran Desert, is highly adapted to heat and drought. It is a sister species of common bean (Phaseolus vulgaris L.), the most important legume protein source for direct human consumption, and whose production is threatened by climate change. Analysis of the tepary genome revealed mechanisms for resilience to moderate heat stress and a reduced disease resistance gene repertoire, consistent with adaptation to arid, hot environments. Extensive...

QTL × environment interactions underlie adaptive divergence in switchgrass across a large latitudinal gradient

Fritschi & Thomas E. Juenger
Local adaptation is the process by which natural selection drives adaptive phenotypic divergence across environmental gradients. Theory suggests that local adaptation results from genetic trade-offs at individual genetic loci, where adaptation to one set of environmental conditions results in a cost to fitness in alternative environments. However, the degree to which there are costs associated with local adaptation is poorly understood because most of these experiments rely on two-site reciprocal transplant experiments. Here, we quantify...

Switchgrass v5 4-way (AP13 x DAC, WBC x VS16) genetic map

John Lovell, Adam Healey, Jeremy Schmutz & Thomas Juenger
Here we present the genetic map construction methods for the switchgrass 4-way mapping population. The map spans 750 recombinant 4-way (pseudo F2) progeny genotyped at 4700 markers. These data are formatted for simple input into R/qtl and most other QTL mapping programs.
