“…The first direct evidence of Na + transport mediated by a CAX from a photosynthetic organism came from work in the green alga Chlamydomonas reinhardtii (Pittman et al . 2009), yet Na + transport activity for a higher plant CAX has not been seen, apart from vacuolar Na + sequestration via Na + /Ca 2+ exchange by AtNCL (Li et al . 2016).…”

“…It was shown that CAX1 from the chlorophyllian unicellular alga Chlamydomonas reinhardtii mediates vacuolar proton gradient-dependent Ca 2ϩ and Na ϩ exchange activity when expressed in yeast (23). Furthermore, co-expression of AtCAX1 and AtCAX3 in yeast cells leads to the formation of "hetero-CAX" complexes able to transport Li ϩ without affecting Ca 2ϩ transport rate (24).…”

“…Correspondingly, these CAXs improve Ca 2+ accumulation (Hirschi, 1999), enhance tolerance to Cd 2+ (Korenkov et al, 2007a, b;Wu et al, 2011), and Li + and Na + (Luo et al, 2005) when expressed constitutively in plant tissues. In addition, some of CAXs are also involved in plant various stresses responses, including low temperatures, dehydration and high salt (Knight et al, 1996;Pittman et al, 2009;Han et al, 2011). Nevertheless, the fact that Atcax1 mutant showed stronger cold acclimation response and CAX1 transgenic tobacco had higher cold sensitivity, but cax3 mutant exhibited reduced salt tolerance, these demonstrated that different CAXs have distinct characteristics and play diverse roles in plant adaptation to various environmental conditions (Hirschi, 1999;Catala et al, 2003;Zhao et al, 2008).…”
