ACCICER — Glycine max

Summary

GmACCICER (GLYMA_20G164900V4) on soybean chromosome 20 encodes a protein with chitinase and lysozyme activity, belonging to the glycosyl hydrolase 18 family and binding calcium ions. This gene is associated with chitin breakdown, amino sugar metabolism, polysaccharide breakdown, and cellular detoxification. It is linked to abscission, floral organ abscission, regeneration, spore germination, hatching, auxin anabolism, secondary metabolism, lignin anabolism, salicylic acid-mediated signaling, immune response, and nitric oxide storage. The encoded protein localizes to the amyloplast, vacuole, and extracellular space. Associations with agronomic traits include leaf dry weight, root fresh and dry weight, root number, lateral root number, root length, plant height, chlorophyll content, and hydrogen peroxide levels. Studies of related genes in other species link the family to seed hardness, seed weight, seed dormancy, protein content, phosphorus content, biomass yield, root volume, root weight, and drought tolerance.
