ABF2 — Cucumis melo

Summary

MELO3C010850.2 (CmABF2) on melon chromosome 4 encodes a bZIP protein of the BZIP46-like family with calcium-dependent protein kinase activity, protein phosphatase activity, and sequence-specific DNA binding. The gene is associated with upregulation of chlorophyll breakdown, positive regulation of leaf senescence, regulation of stomatal opening, and glucose-mediated signaling. It is linked to drought escape via an ABA-dependent pathway, flowering under drought stress, and responses to abiotic stimuli. Associations include traits such as water stress response, submergence tolerance, photosynthetic ability, biomass yield, seed set percent, vegetative vigor, and photoperiod-sensitive flowering time. The gene is also connected to nitrate signaling, aluminum tolerance, thermotolerance, and salinity tolerance. Related genes in other species are linked to dehydration response, drought tolerance, and cold-regulated gene expression.
