CAX7 — Brassica oleracea

Summary

BoCAX7 (CAX7, CCX1) on cabbage chromosome 9 encodes a sodium/calcium exchanger belonging to the CaCA antiporter family, with a NaCa_Exmemb domain and NCX ion-binding domain superfamily, and localises to the plasmalemma. The gene is associated with calcium homeostasis and reactive oxygen species homeostasis, as well as with virus-induced post-transcriptional gene silencing and leaf senescence. Studies of related genes in other species link the family to leaf senescence traits and salt tolerance.
