H69 — Zea mays

Summary

ZM00001EB033870, also known as H69, RS1, or ZmSIP1, encodes a raffinose synthase (EC 2.4.1.82) with galactinol-raffinose galactosyltransferase activity, belonging to the glycosyl hydrolase 36 family. The gene is associated with stachyose and oligosaccharide anabolism, meristem maintenance, seed development and germination, cell division, and response to thirst. It is linked to leaf morphology, photosynthetic rate, drought tolerance, and leaf senescence, as well as salicylic and jasmonic acid responses. The product localizes to the cytoplasm. Studies of related genes in other species connect the family to leaf senescence, anthesis time, and developmental traits including late flowering and reduced fertility.
