FHA — Cucumis sativus

Summary

CsFHA (CSA_3G889670) on cucumber chromosome 3 encodes a photolyase/cryptochrome alpha/beta domain-containing protein with DNA (6-4) photolyase activity, CPD photolyase activity, blue light photoreceptor activity, and histone kinase activity. The gene is associated with photoreactive repair, pyrimidine dimer repair, regulation of post-embryonic development, floral organ morphogenesis, and detection of light. It has been linked to numerous agronomic traits including grain yield, fruit length and growth, leaf area, seed set, photoperiod sensitivity, blue and red light sensitivity, UV light sensitivity, viral disease response, and phenolic compound content. The protein localizes to chloroplast nucleoids, nuclear bodies, SCF complexes, and plant-type vacuoles. Studies of related genes in other species link the family to UV damage repair and tolerance, fruit antioxidant content, and high-intensity light resistance.
