Additional material to the manuscript （Genome-wide Identification and Functional Characterization of RxLR Effectors in <i>Phytophthora cinnamomi</i> Infecting <i>Carya cathayensis</i> Sarg.）

Here, we present a high-quality genome assembly of <i>P. cinnamomi</i> strain ST402 isolated from an economically important Chinese hickory (<i>Carya cathayensis</i> Sarg.), revealing 149 putative RxLR effectors. Transcriptomic profiling during early infection stages (0-36 h post-inoculation) identified 67 differentially expressed RxLR effectors, with four highly induced candidates (PciRxLR1, PciRxLR21, PciRxLR57 and PciRxLR69) demonstrating cell death suppression activity against pathogen-associated molecular patterns (PAMPs) and promoting <i>Phytophthora</i> pathogenicity in <i>Nicotiana benthamiana</i>. Subcellular localization revealed distinct nuclear and cytoplasmic targeting patterns of these effectors. Our findings provide critical insights into molecular mechanisms underlying <i>P. cinnamomi</i> virulence and lay the foundation for developing targeted control strategies against this destructive pathogen.
