Genetic Insights Into Pathways Supporting Optimized Biological Nitrogen Fixation in Chickpea and Their Interaction With Disease Resistance Breeding.

ABSTRACT: In chickpea (Cicer arietinum), a globally important grain legume, improvements in yield stability are required to address food security and agricultural land loss. One approach is to improve both nutrient acquisition through symbiosis with rhizobial bacteria and biotic stress resistance. To support the simultaneous selection of multiple beneficial traits, we sought to identify quantitative trait loci (QTL) and genes linked to improved plant-microbe symbiosis both under symbiosis-promotive growth conditions and when pathogens are present. Our aims were to use the chickpea-Mesorhizobium rhizobial model to identify QTL associated with biological nitrogen fixation (BNF) and nutrient acquisition and understand factors promotive of sustained BNF under biotic stress through the impact of Phytopht
