Verbatim
e1“The genome of two genetically and phenotypically distinct P. cinnamomi isolates collected from avocado orchards in California were sequenced using PacBio and Illumina sequencing”
e6“Overall, our results suggested that clonal P. cinnamomi isolates employ similar strategies as other Phytophthora spp. to increase phenotypic diversity (e.g., polyploidization, gene duplications, and a bipartite genome architecture) to cope with environmental changes”

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 Both P. cinnamomi isolates exhibit complex heterozygous genomes fitting the two-speed genome model
- 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
