研究发现MAPK级联信号成员OsMAPK6是苗期冷胁迫的一个新的正调控因子。OsMAPK6组成型激活形式的过表达转基因植株(CAMAPK6-OE)苗期耐冷性显著提高,表现为低温胁迫下幼苗存活率升高、离子渗透率下降、苔盼蓝染色程度降低、冷胁迫响应基因OsTPP1和OsCBFs的表达水平显著升高;而osmapk6突变体(dsg1)与之完全相反。这表明...
Besides, we found that OsMAPK6 interacts with and phosphorylates two key regulators in rice cold signaling, OsIPA1 and OsICE1, and then enhance their protein stability. Overall, our results revealed a cold-induced OsMAPK6-OsICE1/OsIPA1 signaling cascade by which OsMAPK6 was involved in rice...

是要解决现有水稻生长过程中,苗期遭遇冷害后存活率低的问题.OsMAPK6基因在提高水稻期耐冷性中的应用.即在遭遇低温胁迫后,OsMAPK6突变体dsg1存活率显著下降,离子渗透率显著升高,苯胺蓝染色显著加强,低温响应基因的表达水平显著降低,而OsMAPK6组成型过表达转基因植株CAMAPK6OE与之完全相反.本发明为水稻育种提供重要...
osmapk6 mutant.The gene OsMAPK6 was expressed throughout the plant but predominantly in the microspore mother cells,tapetal cells,and microspores in the anther sac.Compared with the wild type,the total number of microspores was reduced in the osmapk6 mutant.The formation of microspore mother ...
In addition, our genetic and molecular results suggest that the OsMAPK6-GW6a and CLG1-GW6a axes are crucial and operate in a non-additive manner to control grain size. Overall, our findings identify a previously unknown mechanism by which phosphorylation and ubiquitylation non-additively stabilize...
