RSH — Cucumis melo

Summary

MELO3C006843.2, designated CmRSH on melon chromosome 7, encodes a structural constituent of the cell wall belonging to the embryo-specific ATS3 and PLAT/LH2 domain families. The gene is associated with rhamnogalacturonan II biosynthetic process, dedifferentiation, water transport, plant-type cell wall organization and modification, lignin anabolism, flower and root development, and defence response to bacteria. It localizes to the plant-type cell wall, membrane and plasmalemma. CmRSH is associated with lignin content and drought tolerance, and phenotypes linked to the gene include Agrobacterium tumefaciens transformation efficiency, cell wall integrity, plant viability, cell division, cotyledon opening and flowering time. Studies of related genes in other species link the family to transformation efficiency, cell wall assembly, organ expansion, seed germination and dehydration response.
