AP2 — Glycine max

Summary

GmAP2 (GLYMA_15G110200V4) on soybean chromosome 15 encodes an aspartic endopeptidase with endopeptidase activity, belonging to the aspartic peptidase A1 family and containing saposin-like domains. This gene is associated with leaflet morphogenesis, seed growth, leaf abscission, and responses to water, light intensity, and glyphosate. It has been linked to numerous agronomic traits including grain yield per plant, seed weight, seed length, seed longevity, germination rate, plant height, root traits, leaf relative water content, net photosynthetic rate, transpiration rate, stomatal resistance, drought tolerance, salt response, and protein content. The encoded protein localizes to vacuoles, protein storage vacuoles, secretory vesicles, plasmodesmata, and the nucleus. Related genes in other species are linked to floral organ number, meristem identity, and stomatal opening.
