Cultivar-specific responses of the citrus endophytic microbiome to <i>Xanthomonas citri</i> subsp. <i>citri</i> infection reveals <i>Lysobacter</i> as a key biocontrol taxon.

ABSTRACT:

Introduction

Citrus canker, caused by Xanthomonas citri subsp. citri (Xcc), is a major threat to citrus production worldwide, resulting in significant losses in yield and fruit quality. This study investigates the differential responses of endophytic microbial communities to Xcc infection in citrus cultivars with distinct resistance levels, specifically comparing the highly susceptible Citrus reticulata cv. 'Orah' and the more resistant Fortunella crassifolia cv. 'Cuimi'. Through high-throughput amplicon sequencing, we characterized the bacterial and fungal communities in both cultivars before and after Xcc inoculation.

Results

The results revealed distinct shifts in microbial diversity, with bacterial community diversity larg
