Genome-wide identification of NDR1/HIN1-like genes in kiwifruit and function analysis of AeNHL17 in response to disease resistance.

ABSTRACT:

Background

NDR1/HIN1-like (NHL) genes play crucial roles in Psa resistance. Kiwifruit canker, caused by Pseudomonas syringae pv. Actinidiae (Psa) infection is one of the most serious diseases affecting the kiwifruit industry. However, the key NHL has not yet been identified in kiwifruit.

Results

In this study, we conducted a genome-wide identification of NHL family in kiwifruit (Actinidia eriantha). A total of 33 AeNHLs were divided into five domain-conserved subfamilies, which were mainly assigned into phytohormones and defense responses. The expression of AeNHL genes was analyzed to identify key genes in response to Psa, and we found AeNHL17 was highly expressed upon Psa inoculation. Transgenic tobacco overexpressing AeNHL17 presented higher resistance to Psa than wild-typ
