Two double mutants carrying pea symbiotic gene pairs sym13, sym40 and sym33, sym40, respectively, were constructed using single mutants blocked at different nodule developmental stages: E135f (sym13), SGEFix–‑1 (sym40) and SGEFix–‑2 (sym33). The epistasis of the mutant allele sym40 over the mutant allele sym13 and sym33 over sym40 was shown with respect to nodule histological and ultrastructural organisation. Thus, the proposed earlier sequential functioning of genes during infection process: Sym33→Sym40→Sym13 has been confirmed.

Using pea single mutant lines SGEFix–-2 (sym33) and RisFixV (sym42), which are characterized by different abnormalities during symbiotic nodule development, including thickening of infection threads’ walls, a double mutant RBT4 line, carrying a pair of symbiotic genes sym33 and sym42 was constructed. The epistasis of the mutant allele sym33 over the mutant allele sym42 with respect to the histological and ultrastructural organisation of nodules was shown. Thus, it was demonstrated that Sym33 gene functions earlier in symbiotic nodule development than Sym42 gene.

The IPD3/CYCLOPS transcription factor was shown to be involved in the regulation of nodule primordia development and subsequent stages of nodule differentiation. In contrast to early stages, the stages related to nodule differentiation remain less studied. Recently, we have shown that the accumulation of cytokinin at later stages may significantly impact nodule development. This conclusion was based on a comparative analysis of cytokinin localization between pea wild type and ipd3/cyclops mutants. However, the role of cytokinin at these later stages of nodulation is still far from understood. To determine a set of genes involved in the regulation of later stages of nodule development connected with infection progress, intracellular accommodation, as well as plant tissue and bacteroid differentiation, the RNA-seq analysis of pea mutant SGEFix--2 (sym33) nodules impaired in these processes compared to wild type SGE nodules was performed. To verify cytokinin’s influence on late nodule development stages, the comparative RNA-seq analysis of SGEFix--2 (sym33) mutant plants treated with cytokinin was also conducted. Findings suggest a significant role of cytokinin in the regulation of later stages of nodule development.

The infection of root cells of legumes with rhizobia involves the gradual remodelling of the plant-microbial interface. General and species-specific features of symbiotic interface remodelling during nodule development were demonstrated.
