ObjectiveBacterial canker is a destructive disease of kiwifruit caused by the Gram-negative bacterium Pseudomonas syringae pv. actinidiae (Psa). To understand the disease-causing mechanism of Psa, a kiwifruit yeast two-hybrid cDNA library was constructed to identify putative host targets of the Psa Type Three Secreted Effector AvrPto5.ResultsIn this study, we used the Mate & Plate™ yeast two-hybrid library method for constructing a kiwifruit cDNA library from messenger RNA of young leaves. The constructed library consisted of 2.15 × 106 independent clones with an average insert size of 1.52 kb. The screening of the kiwifruit yeast two-hybrid cDNA library with Psa AvrPto5 revealed the interaction of a V-type proton ATPase subunit-H, a proline rich-protein and heavy metal-associated isoprenylated plant protein 26. Among these, heavy metal-associated isoprenylated plant protein 26 showed a positive interaction with Psa AvrPto5 as both prey and bait.Electronic supplementary materialThe online version of this article (10.1186/s13104-019-4102-x) contains supplementary material, which is available to authorized users.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
