Other claims from this paper (7)
- Method / resource The two P. cinnamomi isolates from avocado orchards were assembled de novo to 140–141 Mb genomes
- Method / resource The two P. cinnamomi genome assemblies contain 21,111–21,402 gene models
- Observation The more virulent P. cinnamomi isolate has a larger secretome than the less virulent isolate
- Observation The more virulent P. cinnamomi isolate encodes more RXLR effectors than the less virulent isolate
- Observation P. cinnamomi deploys common gene repertoires in all infected hosts
- Observation P. cinnamomi deploys host-specific gene subsets, especially among effectors
- Mechanism Clonal P. cinnamomi isolates increase phenotypic diversity through polyploidization, gene duplications and a bipartite genome architecture, as other Phytophthora spp. do
