OsSWEET13(ABA98216, Zhou et al. 2015; Os12g29220, Streubel et al. 2013, Richter et al. 2014, Mathan et al. 2021), 與Xa25(AK242853/Os12g29220, Liu et al. 2011), 位于同一基因位點(diǎn)... 【定位與克隆】通過珍汕97/明恢63的感/抗組合單粒傳獲得241個重組自交系群體,Xa-25定位于水稻第12染色體上RFLP標(biāo)記R887和G1314之間,與兩者的圖距分別為3.0 cM和7.3 cM,該區(qū)域與稻瘟病抗性基因Pi-ta/Pi-ta2所在區(qū)域相近(Chen et al., 2002)。 x25位于水稻12號染色體的著絲粒區(qū)域,通過抑制白葉枯病菌的生長,在水稻苗期和成熟期表現(xiàn)出對菌株P(guān)XO339的小種;剐。x25 編碼一個屬M(fèi)tN3/saliva家族的蛋白,在真核生物中普遍存在。隱性的xa25和顯性的Xa25各自編碼的蛋白具有8個氨基酸的差異,不同的白葉枯病菌中只有PXO339能迅速誘導(dǎo)Xa25的表達(dá),但不能誘導(dǎo)xa25 表達(dá)(Liu et al. 2011)。 【生物學(xué)功能】蔗糖轉(zhuǎn)運(yùn)蛋白基因OsSWEET13能夠作為TAL效應(yīng)子PthXo2作用的易感病基因,由于粳稻中OsSWEET13啟動子的變化,存在潛在的對PthXo2介導(dǎo)的白葉枯病的隱性抗性(Zhou et al. 2015)。 OsbZIP72能直接與OsSWEET13和OsSWEET15的啟動子結(jié)合并激活其表達(dá),從而調(diào)節(jié)蔗糖運(yùn)輸和分布以響應(yīng)非生物脅迫,有助于在干旱和鹽脅迫下維持水稻的糖穩(wěn)態(tài)(Mathan et al. 2021)。 【相關(guān)登錄號】
