New sources of Sym2^A allele in the pea (Pisum sativum L.) carry the unique variant of candidate LysM-RLK gene LykX.

ABSTRACT: At the onset of legume-rhizobial symbiosis, the mutual recognition of partners occurs based on a complicated interaction between signal molecules and receptors. Bacterial signal molecules named Nod factors ("nodulation factors") are perceived by the plant LysM-containing receptor-like kinases (LysM-RLKs) that recognize details of its structure (i.e., unique substitutions), thus providing the conditions particular to symbiosis. In the garden pea (Pisum sativum L.), the allelic state of Sym2 gene has long been reported to regulate the symbiotic specificity: for infection to be successful, plants with the Sym2 ^A allele (for "Sym2 Afghan", as these genotypes originate mostly from Afghanistan) require an additional acetylation of the Nod factor which is ir
