摘      要：Phosphorus is one of mineral elements essential for plant growth and *** cope with low phosphate(Pi)conditions,plants have evolved complex signaling mechanisms including the inositol phosphate(InsP)signaling pathway in which the phosphate starvation response(PHR)transcription factors control the expression of Pi starvation-induced genes in a Pi-dependent *** activities of PHRs are regulated by their interactions with SPX proteins that act as receptors for inositol pyrophosphates(PP-lnsPs),such as lnsP7 and *** plants,the syn thesis of lnsP8 is mediated by the bifunctional kinase/phosphatase enzymes,VIH1 and ***,lnsP6 kinases responsible for the synthesis of lnsP7 in plants have long remained elusive.
