中關(guān)村nmt聯(lián)盟活體研究通訊222期上周,中國(guó)農(nóng)大郭巖課題組在nature communications在線發(fā)表題為calcium-activated 14-3-3 proteins as a molecular switch in salt stress tolerance的研究成果。
研究揭示了14-3-3蛋白通過感受鈣信號(hào),選擇性的結(jié)合和抑制sos2和pks5的激酶活性,并協(xié)同調(diào)控na+/h+反向轉(zhuǎn)運(yùn)蛋白sos1和質(zhì)膜h+-atpase活性,影響植物耐鹽能力。
