However, how SPX-PHR signaling module regulates the expression of miRNAs in response to long-term Pi starvation in rice remains elusive. A genome-wide analysis of the expression files of miRNAs that are responsive to Pi-starvation and resupply in roots of WT, Osphr2, Osphr13, Osphr123, ...
已有研究表明:低磷条件下,水稻磷稳态调控的核心转录因子–PHR2通过二聚化结合顺式调控元件(P1BS),激活一系列磷饥饿响应基因的表达,促进磷的吸收与利用;高磷条件下,SPX2蛋白感知磷信号,进而结合并抑制PHR2的转录活性,维持磷稳态,避免磷中毒。但SPX2如何感知和传递磷信号的具体分子机制,尚不清楚。 近日,湖北洪山实...

Plant growth depends on the continuous availability of the macro-nutrient phosphate(Pi).However,in most soils,Pi is only poorly accessible to plants,resulting in Pi deficiency and triggering a number of Pi starvation responses.One strategy of plants to over-come Pi limitation is to form a ...
