PthA4AT, a 7.5‐repeats transcription activator‐like (TAL) effector fromXanthomonas citrissp.citri, triggers citrus canker resistance

Abstract: Summary Transcription activator‐like effectors (TALEs) are important effectors of Xanthomonas spp. that manipulate the transcriptome of the host plant, conferring susceptibility or resistance to bacterial infection. Xanthomonas citri ssp. citri variant AT (X. citri AT) triggers a host‐specific hypersensitive response (HR) that suppresses citrus canker development. However, the bacterial effector that elicits this process is unknown. In this study, we show that a 7.5‐repeat TALE is responsible for triggering th… Show more

“…TALEs are pathogenicity determinants in numerous Xanthomonas species that activate host-specific susceptibility (S) genes to promote disease [7]. Conversely, TALEs induce immune responses leading to incompatible interactions [80][81][82][83]. TALE-mediated activation of immune responses in resistant plants can occur by direct induction of the executor resistance (R) gene [18] or by recognition of TALEs by NB-LRR-resistance proteins [15,16].…”

“…This family of genes codes for proteins that trigger the activation of specific plant genes and aid plant infection. While one of these genes (pthA4) is recognized as the major pathogenicity determinant of Xcc pathotype A, Xcc genomes always contain several alternative TALE genes, some of which were found to modify its virulence (47,48). Until recently, TALE genes were thought to be only plasmid encoded in Xcc.…”

“…Indeed, some key phenotypes are encoded by plasmid genes: streptomycin resistance (26), copper resistance (24,27) and most importantly type III transcriptionactivator like effector (TALE) genes (28). Xcc TALEs include a large repertoire of related but highly variable genes, of which pthA4 is required for pathogenicity (29).…”

“…This indicates that the absence of canker-like symptoms in lemon leaves infected by an A T strain is not solely an effect of the absence of a functional pthA4 gene. That was confirmed by the inability of A T strains to cause canker in lemon leaves even after the introduction of the pthA4 virulence gene (Roeschlin et al 2019).…”
