AP2 — Medicago truncatula

Summary

MTR_4G132420 (MtAP2) encodes a protein with saposin-like domains and aspartic peptidase A1 domains, and has been annotated with aspartic endopeptidase activity. This gene is associated with acquisition of desiccation tolerance, regulation of seed maturation, seed growth, and organ growth. It is also linked to nitrogen fixation, cytokinin and ethylene anabolism, sucrose metabolism, lipogenesis, secondary metabolism, abscission, and responses to cadmium and light intensity. The encoded protein localises to the protein storage vacuole, secretory vesicle, vacuole, plasmodesma, nucleus, and extracellular space. MtAP2 is associated with seed longevity, germination rate, drought tolerance, salt tolerance, photosynthetic rate, stomatal density, and stomatal aperture. Related genes in other species link the family to traits including grain yield, seed weight and size, root biomass, leaf relative water content, and chlorophyll content.
