CHIT3 — Pisum sativum

Summary

PSAT6G194680 (symbol CHIT3, also known as PsACCICER) on garden pea chromosome 6LG2 encodes a protein with chitinase activity, lysozyme activity, and calcium ion binding, belonging to the glycosyl hydrolase 18 family. The gene is associated with chitin and polysaccharide breakdown, amino sugar metabolism, protein secretion, and responses to biotic stimuli, wounding, cadmium, and fungi. It is linked to seed and seedling development, post-embryonic development, nodulation, cell death, and homeostasis, as well as phenylpropanoid anabolism. Localization evidence connects the product to the vacuole, amyloplast, and extracellular space. The gene is associated with protein content and root length traits. Related genes in other species link the family to chitinase enzyme classes 3.2.1.14 and 3.2.1.17, and to traits including seed weight, seed hardness, seed dormancy, plant height, biomass yield, chlorophyll content, drought tolerance, and root system architecture.
