Phytoalexin production elicited by exogenously applied jasmonic acid in rice leaves (Oryza sativa L.) is under the control of cytokinins and ascorbic acid.

abstract：:Acylphosphatase (AcP) activity in prokaryotes was classically attributed to some aspecific acid phosphatases. We identified an open reading frame for a putative AcP in the b0968 Escherichia coli gene and purified the recombinant enzyme after checking by RT-PCR that it was indeed expressed. EcoAcP has a predicted typic...
