Kamran, Muhammad published the artcileRole of TaALMT1 malate-GABA transporter in alkaline pH tolerance of wheat, SDS of cas: 97-67-6, the main research area is ALMT1 GABA transporter alk pH tolerance wheat; Hordeum vulgare; Triticum aestivum; aluminate; aluminum; barley; gama-aminobutyric acid; proton efflux; rhizosphere acidification.
Malate exudation through wheat (Triticum aestivum L) aluminum-activated malate transporter 1 (TaALMT1) confers Al3+ tolerance at low pH, but is also activated by alk. pH, and is regulated by and facilitates significant transport of gamma-aminobutyric acid (GABA, a zwitterionic buffer). Therefore, TaALMT1 may facilitate acidification of an alk. rhizosphere by promoting exudation of both malate and GABA. Here, the performance of wheat near isogenic lines ET8 (Al+3-tolerant, high TaALMT1 expression) and ES8 (Al+3-sensitive, low TaALMT1 expression) are compared. Root growth (at 5 wk) was higher for ET8 than ES8 at pH 9. ET8 roots exuded more malate and GABA at high pH and acidified the rhizosphere more rapidly. GABA and malate exudation was enhanced at high pH by the addition of aluminate in both ET8 and transgenic barley expressing TaALMT1. Xenopus laevis oocytes expressing TaALMT1 acidified an alk. media more rapidly than controls corresponding to higher GABA efflux. TaALMT1 expression did not change under alk. conditions but key genes involved in GABA turnover changed in accordance with a high rate of GABA synthesis. We propose that TaALMT1 plays a role in alk. tolerance by exuding malate and GABA, possibly coupled to proton efflux.
