MdHMGB15-MdXERICO-MdNRP module mediates salt tolerance of apple by regulating the expression of salt stress-related genes.

ABSTRACT:

Introduction

Soil salinity is an important limiting factor for plant growth. As a RING-type E3 ubiquitin ligase, MdXERICO is highly responsive to salt stress and can enhance the salt tolerance of plants. However, the molecular mechanism for the response of MdXERICO to salt stress remains unclear.

Objectives

This study aims to dissect the molecular mechanisms for MdXERICO to regulate plant response to salt stress.

Methods

Transcriptome data were compared to obtain the salt stress-induced gene MdXERICO. Transgenic apple seedlings, apple calli, Arabidopsis, and tomato material were obtained using Agrobacterium-mediated transformation assays. Semiendogenous co-immunoprecipitation analysis, yeast two-hybrid, pull-down and dual-luciferase reporter system were used to detect
