Résumé
Agricultural output can be reduced by abiotic stressors including lack of rainfall, shortage of irrigation water, unseasonably cold temperatures and saline soil, or biotic stressors including insects and microbial pathogens. Tolerance of abiotic and biotic stresses from seedling emergence through delivery of the final product can avoid losses of billions of $ annually in the US. Crop plant germplasm generally contains genetic diversity that remains a rich resource for further gains in plant performance in relation to this suite of environmental stresses. Genetic determinants of tolerance and resistance traits can be located genetically and followed in plant breeding schemes using nearby molecular markers. Each marked trait determinant also provides an opportunity to develop a mechanistic understanding of the underlying genes and proteins by applying molecular and cellular research methods. This project provides molecular markers for a range of environmental stress tolerance and resistance traits in crop plants, mainly cowpea, which is historically and presently a California crop while also being a strategic crop for a more resource-challenged future. This project integrates molecular markers and knowledge of naturally occurring genetic variability within the species into cowpea breeding and germplasm management for California, nationally and worldwide. This project also encompasses exploration of a specific example of apparent genome plasticity in a cluster of barley genes encoding drought-related proteins called dehydrins.
