AP2 — Glycine max

Summary

GmAP2 (GLYMA_17G011500V4) encodes an aspartic endopeptidase with endopeptidase activity, belonging to the Saposin-like and aspartic peptidase A1 domain families. In soybean, this gene is associated with leaflet morphogenesis, seed growth, dehiscence, leaf abscission, and responses to water, light intensity, and glyphosate. It is also linked to hydrogen peroxide metabolism, sucrose and hormone anabolism, iron transport, and protein storage. Localization evidence places the product in the protein storage vacuole, vacuole, plasmodesma, nucleus, and extracellular space. Trait associations include grain yield, seed length, seed weight, seed size, seed longevity, germination rate, protein content, sugar content, chlorophyll content, net photosynthetic rate, transpiration rate, stomatal resistance, stomatal density and aperture, root and stem fresh and dry weight, leaflet number, and salt response. Related genes in other species connect the family to abscisic acid sensitivity, auxin content, and stomatal opening.
