Article Synopsis
  • - The study focuses on the genetic analysis of chitinase enzymes from neotropical fungal isolates, which are important for agricultural biological control due to their ability to break down chitin, a component of insect exoskeletons and fungal cell walls.
  • - Researchers examined eight genomes, discovering eleven chitinase 1 genes categorized into two types and highlighting variations particularly in chitinase 1, which may indicate different roles in infection and growth processes.
  • - The findings stress the significance of local fungal genomes in understanding pathogen-host interactions and suggest practical agricultural applications, emphasizing the need for more experimental work to validate these computational insights.

is an entomopathogenic fungus used in agriculture as a biological controller worldwide. Despite being a well-studied organism, there are no genomic studies of isolates from Central American and Caribbean countries. This work characterized the functional potential of eight Neotropical isolates and provided an overview of their genomic characteristics, targeting genes associated with pathogenicity, the production of secondary metabolites, and the identification of CAZYmes as tools for future biotechnological applications.

Beauveria bassiana, a well-known entomopathogenic fungus, has a worldwide distribution; however, genomes of isolates from the Neotropical region are scarce. Here, we report the draft genome sequences of eight bassiana isolates from Costa Rica, Puerto Rico, and Honduras.

The genus Beauveria comprises economically important entomopathogenic fungi, widely used for biological control in agriculture. Interest in these organisms in Costa Rica prompted surveys and establishment of collections in the past two decades. However, there was neither a formal identification nor a characterization of the isolates.

Cocoa fermentation is the first step in the post-harvest processing chain of cocoa and is important for the removal of the cocoa pulp surrounding the beans and the development of flavor and color precursors. In the present study, metagenomic and metatranscriptomic sequencing were applied to Costa Rican cocoa fermentation processes to unravel the microbial diversity and assess the function and transcription of their genes, thereby increasing the knowledge of this spontaneous fermentation process. Among 97 genera found in these fermentation processes, the major ones were , , , and The most prominent species were , , and among the LAB, and among the AAB, and and among the yeasts.
