Atypical RXLR effectors are involved in <i>Phytophthora cactorum</i> pathogenesis.

ABSTRACT: RXLR effectors are pathogenic factors secreted from oomycetes to manipulate the immunity of the host. Typical RXLR effectors contain an RXLR-dEER motif at the N-terminus, whereas atypical RXLRs show variations on this motif. The oomycete Phytophthora cactorum is known to infect over 200 plant species, resulting in significant agricultural economic losses. Although genome-wide identification and functional analyses of typical RXLRs from P. cactorum have been performed, little is known of atypical PcaRXLRs. Here, we identified RXLRs, both typical and atypical, in P. cactorum and compared them with those of other oomycete pathogens. Fewer RXLRs were identified in P. cactorum compared with other Phytophthora species, possibly due to fewer duplication events o
