EFE — Cucumis sativus

Summary

CsEFE (CSA_6G160180) in cucumber (Cucumis sativus) on chromosome 6 encodes an aminocyclopropanecarboxylate oxidase, a 2-oxoglutarate-dependent dioxygenase with ACC oxidase activity that also binds vitamin C and metal ions. This gene is associated with ethylene biosynthesis from methionine and hormone signaling pathways. It is linked to sex determination and differentiation, flower formation, pistil development, shoot regeneration, de-etiolation, and alternative respiration. Associations with agronomic traits include female flowering, plant height, stem elongation, leaf shape, carpel morphology, ethylene sensitivity, drought tolerance, stomatal opening, iron concentration, protein content, and abiotic stress response. The gene is also connected to disease resistance, nitrogen deficiency response, and ethylene production. Studies of related genes in other species link the family to carpel development, adventitious root formation, iron acquisition, and abiotic stress tolerance.
