报告内容摘要?nbsp;
Overexpression (OE) of a purple acid phosphatase (AtPAP2) in Arabidopsis results in faster growth and higher seed yield (+40-50%). The OE lines contained significant higher ATP and sucrose levels and a higher ATP/NADPH ratio than the wild-type (WT). Subcellular localization studies showed that this phosphatase is anchored on the outer membranes of the two energy generating organelles of plants, chloroplasts and mitochondria via its C-terminal hydrophobic motif and removal of this motif abolishes the growth-promoting activity of AtPAP2. Surprisingly, transgenic lines that only express AtPAP2 on mitochondria (P2-TOM) shows early senescence phenotypes and they contain a significant lower leaf sucrose content then the wild type. Here, we provide experimental evidence to show that AtPAP2 modulate the energy output from these two organelles by affecting import of nuclear-encoded proteins into these two organelles. These findings may have application values in agrobiotechnology、/P>
