SIS7 — Glycine max

Summary

GmSIS7 (GLYMA_15G250100V4) on soybean chromosome 15 encodes a carotenoid dioxygenase with 9-cis-epoxycarotenoid dioxygenase activity and metal binding, placing it in the carotenoid oxygenase family. The gene is associated with abscisic acid biosynthesis and accumulation, stomatal movement and closure, seed dormancy and germination, and responses to salt, drought, osmotic, cold, and high light stress. It has also been connected to photosynthetic rate, chlorophyll content, ethylene sensitivity, phosphorus uptake, anther development, fruit ripening, leaf senescence, and branching. The product localizes to the chloroplast thylakoid membrane and stroma. Related genes in other species link the family to drought tolerance, ABA accumulation under stress, transpiration rate, and lateral root development, as well as seed development and dormancy.
