CXE10 — Arabidopsis thaliana

Summary

AT3G05120, also known as CXE10 or GID1A, encodes a protein with carboxylesterase activity, ent-kaurene oxidase activity, oxygen binding, gibberellin binding, and hydrolase activity, belonging to the alpha/beta hydrolase family. This gene is associated with gibberellin sensitivity and gibberellin-mediated signalling, as well as fruit morphogenesis, flower formation, and responses to light, strigolactone, and magnetism. It has been linked to numerous traits including seedling cotyledon number and size, leaf area and elongation rate, plant size, seed set, cellulose content, and responses to temperature stress, viral disease, and light quality. Additional associations include root development, xylem development, water use efficiency, fruit ripening, seed germination, auxin and glucosinolate biosynthesis, and defense against biotrophic pathogens. The protein localizes to the nucleus, cytosol, chloroplast outer membrane, and endoplasmic reticulum. Studies of related genes in other species connect the family to harvest index, fruit ripening, fruit weight, and dwarf phenotypes.
