RASTL-4 — Zea mays

Summary

ZM00001EB032600 (RASTL-4) on maize chromosome 1 encodes a thaumatin-like protein belonging to the osmotin/thaumatin-like superfamily and is annotated with beta-glucanase activity, endo-1,3(4)-beta-glucanase activity, and mRNA binding. The gene is associated with biological processes including antifungal innate immune response, salicylic acid metabolism, phytoalexin biosynthesis, downregulation of photosynthesis, sex determination, and response to potassium ion. It is linked to localisation in the apoplast, plant-type cell wall, vacuole, plasmodesma, and secretory vesicle. RASTL-4 is associated with traits such as grain yield, grain size, plant height, root length, anthesis-silking interval, drought tolerance, protein content, and heterosis, as well as disease resistance, pathogen defense, and insect resistance.
