Article Synopsis
- - In February 2022, 16 Canary Island date palms in Mexico City displayed symptoms of pink rot disease, with a 27% incidence and 12% severity, showing necrotic lesions that progressed from the petiole to the rachis.
- - Mycelia from infected tissues were cultured on potato dextrose agar, resulting in 20 fungal colonies that resembled the characteristics of a known pathogen, identified as (Biourge) Schroers.
- - Genomic DNA was extracted from one fungal isolate, sequenced for the internal transcribed spacer (ITS) and large subunit (LSU) regions, and placed in a specific phylogenetic clade, confirming its pathogenicity through tests on date
The genetic structure of a sample of isolates of the oomycete plant pathogen from natural and agricultural outbreaks and the long-distance movement of individual genotypes were studied using four microsatellite markers to genotype 159 isolates of Californian, Mexican, and worldwide origins. Allelic profiles identified 75 multilocus genotypes. A STRUCTURE analysis placed them in three groups characterized by different geographic and host ranges, different genic and genotypic diversity, and different reproductive modes.
