Six chickpea genotypes with differing nodulation ability have inconsistent changes in gene expression in known nodulation pathways after inoculation with rhizobia. A Simplified schematic of early signalling events and interactions upon perception of rhizobia by legume roots. B-D Log2 fold change in gene expression for genes involved in B the common symbiotic signalling pathway (CSSP) and autoregulation of nodulation (AON), C cytokinin and auxin hormone responses and D flavonoid biosynthesis pathways in the roots of six chickpea genotypes 3 days after inoculation with M. ciceri
