Eucalyptus grandis WRKY genes provide insight into the role of arbuscular mycorrhizal symbiosis in defense against Ralstonia solanacearum.

ABSTRACT:

Introduction

WRKY transcription factors are essential for plant growth, health, and responses to biotic and abiotic stress.

Methods

In this study, we performed a deep in silico characterization of the WRKY gene family in the genome of Eucalyptus grandis. We also analyzed the expression profiles of these genes upon colonization by the arbuscular mycorrhizal fungus (AMF) Rhizophagus irregularis (Ri) and infection with the bacterial pathogen Ralstonia solanacearum (Rs).

Results

A total of 117 EgWRKYs were identified. Phylogenetic analysis divided the EgWRKY proteins into three groups: group I (21 proteins, 17.95%), group II (65 proteins, 55.56%), and group III (24 proteins, 20.51%). Additionally, seven EgWRKY proteins (5.9
