Yeast two-hybrid library screening enables the discovery of novel protein-protein interactions. Identifying cytosolic host proteins targeted by host-translocated Phytophthora effector proteins relies on the mRNA amount, quality, and composition used to prepare the yeast two-hybrid cDNA library. Here we describe the steps required for the preparation of a Pinus radiata cDNA library optimized for Phytophthora effector target screening in yeast. This method may also be applied to other host plants and pathogen species.

摘要

Yeast two-hybrid library screening enables the discovery of novel protein-protein interactions. Identifying cytosolic host proteins targeted by host-translocated Phytophthora effector proteins relies on the mRNA amount, quality, and composition used to prepare the yeast two-hybrid cDNA library. Here we describe the steps required for the preparation of a Pinus radiata cDNA library optimized for Phytophthora effector target screening in yeast. This method may also be applied to other host plants and pathogen species.
