Scientists have sequenced the full genome of Ceratocystis huliohia, one of two fungi responsible for Rapid 'Ōhi'a Death, a devastating disease wiping out Hawai'i's iconic native 'ōhi'a trees. This genetic blueprint, built from a Maui fungal sample collected in April 2025, gives researchers a precise map of the pathogen to inform disease management and conservation efforts.
The complete genome of Ceratocystis huliohia was successfully assembled using long-read Nanopore sequencing technology, providing high-resolution genetic detail.
The sequenced isolate (C25-5) was collected on the island of Maui in April 2025, representing a geographically specific sample of the pathogen.
C. huliohia is one of two distinct fungal species causing Rapid 'Ōhi'a Death, and having its genome enables comparative study between the two pathogens.
