AN3 — Sorghum bicolor

Summary

SORBI_3001G101700 (SbAN3) on sorghum chromosome 1 encodes an SS18_N domain-containing protein with annotated activities including fucosidase, beta-glucosidase, translation repressor, and ATP-dependent chromatin remodeler activity. The gene is associated with embryonic meristem initiation, floral whorl morphogenesis, organ boundary formation, and seed dormancy maintenance. It localizes to the SAGA complex, SWI-SNF complex, nuclear lamina, and endosperm protein bodies. SbAN3 is linked to numerous agronomic traits including plant organ growth and development, fruit yield, plant size, peduncle length, photoperiod sensitivity, inflorescence development, phyllotaxy, and responses to aphids, aluminum, boron, and copper. Related genes in other species are associated with organ size regulation, leaf cell size, floral development, and drought stress response.
