MAAI — Triticum aestivum

Summary

TRAESCS5B02G303200, designated TaMAAI and also known as TaGSTZ1-5B, encodes a glutathione S-transferase with maleylacetoacetate isomerase activity and glutathione binding capability. This bread wheat gene on chromosome 5B is associated with a wide range of biological processes, including homogentisate breakdown, L-phenylalanine breakdown, ascorbate metabolism, the ascorbate-glutathione cycle, and responses to external biotic stimuli. It has been linked to numerous agronomically important traits such as grain weight, grain number, grain protein content, grain texture, grain length, grains per spike, days to heading, stripe rust, heat tolerance, chlorophyll content, photosynthetic rate, water use efficiency, biomass yield, and root length. The encoded protein localises to the cytoplasm and macromolecular complexes. Studies of related genes in other species connect the family to cold and chilling tolerance.
