DTA1 — Cucumis sativus

Summary

CsDTA1 (CSA_7G413380) on cucumber chromosome 7 encodes a protein with domains including IPNS-like_FE2OG_OXY, DIOX_N, Oxoglu/Fe-dep_dioxygenase, and IPNS-like_sf, and has annotated enzyme activities including gibberellin 2-oxidase activity, gibberellin 3-beta-dioxygenase activity, 2-oxoglutarate dioxygenase activity, and others. The gene is associated with sex determination and differentiation, flower formation and development, abscission, and responses to red/far-red light, light stimulus, fungal molecules, and oomycete defense. It is linked to gibberellin catabolism and biosynthesis, as well as flavonoid, coumarin, and morphine anabolism. Traits associated with CsDTA1 include female flowering, fruit length and size, floral organ identity, ethylene sensitivity, and photosynthetic rate. Phenotypic associations include hypocotyl elongation, seed dormancy, axillary bud formation, lateral branching, and parthenocarpic fruit development. Studies of related genes in other species link the family to somatic embryo production, gibberellin metabolism, and seed germination.
