RD22 — Cucumis melo

Summary

CmRD22 (MELO3C003592.2) on melon chromosome 5 encodes a BURP domain-containing protein with nutrient reservoir activity and mRNA binding. The gene is associated with cellular homeostasis, response to desiccation, abscisic acid response, pollen maturation and development, and salinity response. The protein localizes to the orbicule, exine, protein storage vacuole, Golgi, endosome, and extracellular space. Associations with photosynthetic rate, stomatal resistance, chlorophyll content, and root length have been noted, as well as links to dehydration stress response and salt tolerance. Studies of related genes in other species connect the family to drought tolerance, abscisic acid sensitivity, and traits including carotene content, proline content, germination rate, and stomatal opening.
