Morphological, molecular and pathogenicity characteristics of Fusarium verticillioides causing Fusarium ear rot of corn in Panama.

Zea mays is the second most popular cereal crop in Panama. Its production is intended for human and livestock consumption but is threatened by several diseases. We report the occurrence of Fusarium ear rot, a disease that has affected corn production in a specific region of Panama.

Coffee Leaf Rust () from the Recent Invasion into Hawaii Shares a Genotypic Relationship with Latin American Populations.

Hawaii has long been one of the last coffee-producing regions of the world free of coffee leaf rust (CLR) disease, which is caused by the biotrophic fungus . However, CLR was detected in coffee farms and feral coffee on the island of Maui in February 2020 and subsequently on other islands of the Hawaiian archipelago. The source of the outbreak in Hawaii is not known, and CLR could have entered Hawaii from more than 50 coffee-producing nations that harbor the pathogen.

Diversity of culturable endophytic fungi vary through time in Manihot esculenta Crantz.

Endophytic fungi are a ubiquituos group that colonize all plant species on earth. Studies comparing the location of endophytic fungi within the leaves and the sampling time in Manihot esculenta Crantz (cassava) are limited. In this study, mature leaves of M.

Global Analysis of Populations Shows Clonal Reproduction for the Coffee Leaf Rust Pathogen Throughout Most of Its Range.

is the most important fungal pathogen of coffee and the causal agent of recurrent disease epidemics that have invaded nearly every coffee growing region in the world. The development of coffee varieties resistant to requires fundamental understanding of the biology of the fungus. However, the complete life cycle of remains unknown, and conflicting studies and interpretations exist as to whether the fungus is undergoing sexual reproduction.

The Microbiome of Neotropical Water Striders and Its Potential Role in Codiversification.

Insects host a highly diverse microbiome, which plays a crucial role in insect life. However, the composition and diversity of microbiomes associated with Neotropical freshwater insects is virtually unknown. In addition, the extent to which diversification of this microbiome is associated with host phylogenetic divergence remains to be determined.
