Phosphoinositide-specifie phosphollpase C plays pivotal roles in a host of physiologic processes in both animals and plants. Animal PI-PLC is regulated by heterotrimeric G-protein. Plant PI-PLCs are structurally close to the mammalian PI-PLC-ζ isoform, and it is not testified what regulated this isoform enzyme. In this paper, two isoform genes of LdPLC (Pan, 2005) and three subunits of heterotrimeric G-protein in Arabidopsis were amplified and recombinated with plasmids of a yeast two-hybrid system. Using this system, we provided the evidence that LdPLC1 and Gβ subunit could be able to interact with each other. This result indicated that LdPLC1 might be regulated by Gprotein.
