A subset of genes expressed in chickpea roots after inoculation with Mesorhizobium ciceri differentiate varieties with high nodule formation from those with low nodule formation. A PLS-DA plot of normalized and rlog transformed RNAseq count data for the roots of 6 chickpea genotypes 3 days after inoculation with M. ciceri, with groupings assigned based on nodulation ability (high or low). 95% confidence ellipses for each nodulation level are shown. B Plot of loadings values from A for all expressed genes. Genes having coordinates with r > 0.013 were considered to contribute to the separation of high or low nodulation varieties
