First Report of Postharvest Fruit Rot of Yellow Dragon Fruit ( Selenicereus megalanthus ) Caused by Fusarium sulawesiense in China

Yellow dragon fruit (Selenicereus megalanthus) is a high-value tropical cactus fruit crop. In September 2025, postharvest fruit rot was observed on yellow dragon fruits at a fruit market in Kunming, Yunnan Province, China (102.76°E, 25.03°N), where approximately 38 % (38/100) of inspected fruits were symptomatic.

Evolutionary constraints and regulatory plasticity shape host specialization in the Magnaporthe oryzae species complex

ABSTRACT Rice blast caused by Magnaporthe oryzae threatens global rice production, and wheat blast emergence highlights the pathogen’s capacity for host shifts. Although numerous studies have described M. oryzae genome organization and infection mechanisms, critical questions remain regarding the evolutionary drivers o...

Pangenomic sequencing and gene-unit genome-wide association study insights into genome plasticity and gene functions in Magnaporthe oryzae.

This study provides new insights into the pangenome of Magnaporthe oryzae and introduces a method for the identification of functionally important genes in fungal species.
