Cht2 — Triticum aestivum

Summary

TRAESCS2B02G622200, also known as Cht2 or TaPR-3, encodes a chitinase enzyme with chitinase activity, beta-N-acetylglucosaminidase activity, and chitin binding capability, belonging to the glycosyl hydrolase 19 family. This bread wheat gene on chromosome 2B is associated with powdery mildew resistance, defence response to fungi, and response to biotic stimulus. It is linked to cell wall macromolecule catabolic process, chitin breakdown, amino sugar metabolism, and polysaccharide breakdown. The gene is associated with jasmonic acid signaling pathways, including MYC-induced transcription of JA-induced genes and JAZ/MYC interactions. Associations extend to agronomically important traits such as grain weight, grain yield, plant height, heading time, tiller number, ear number, leaf length, cold tolerance, seed germination, and stem elongation. The encoded protein localises to the vacuole and extracellular space, and is linked to hypersensitive response programmed cell death, flower development, and morphogenesis.
