RSS1 — Triticum turgidum subsp. durum

Summary

TRITD6BV1G128590, designated RSS1 on durum wheat chromosome 6B, encodes the RL1 protein. The gene is associated with cell cycle control and meristem maintenance. RSS1 has been connected to starch biosynthesis, phytohormone responses, particularly cytokinin, and resistance traits. Studies of the rice relative RSS1 link the gene family to cell cycle regulation, meristem and shoot development, seed and endosperm formation, and tolerance to salt stress, with associated dwarf phenotypes. Sequence similarity connections further associate the family with grain size and wheat stripe rust disease response.
