LHP1 — Cucumis melo

Summary

MELO3C022484.2, designated CmLHP1 (also known as CmTFL2), encodes a chromodomain-containing protein with histone-binding and chromatin-binding activities, and is annotated as a structural constituent of chromatin. In melon, CmLHP1 is associated with heterochromatin organization, maintenance of inflorescence meristem identity, sex determination, floral whorl development, sepal formation, leaf shaping, and shoot morphogenesis. The gene is linked to numerous agronomic traits including yield, photoperiod-sensitive flowering time, vegetative to reproductive phase transition, flower and inflorescence development, leaf morphology, trichome morphology, anthocyanin content, sulfur content, auxin content, cytokinin sensitivity, ethylene sensitivity, and resistance to the root-knot nematode Meloidogyne incognita and aphids. CmLHP1 is also associated with responses to abiotic stress, radiation, and jasmonic acid, as well as endosperm morphology and seed maturation.
