Genomic and Transcriptomic Analysis of Pea (Pisum sativum L.) Breeding Line 'Triumph' with High Symbiotic Responsivity.

ABSTRACT: Pea (Pisum sativum L.), like most legumes, forms mutualistic symbioses with nodule bacteria and arbuscular mycorrhizal (AM) fungi. The positive effect of inoculation is partially determined by the plant genotype; thus, pea varieties with high and low symbiotic responsivity have been described, but the molecular genetic basis of this trait remains unknown. Here, we compare the symbiotically responsive breeding line 'Triumph' of grain pea with its parental cultivars 'Vendevil' (a donor of high symbiotic responsivity) and 'Classic' (a donor of agriculturally valuable traits) using genome and transcriptome sequencing. We show that 'Triumph' inherited one-fourth of its genome from 'Vendevil', including the genes related to AM and nodule formation, and reveal that under combined inoculati
