Environmental Microbiology, Volume 26, Issue 6, June 2024.We sequenced water samples from 44 lakes by shotgun sequencing, followed by binning them into metagenome‐assembled genomes. The genomic information from these genomes along with nutrient measurements was used for phylogenetic and ecological analysis. Abstract Understanding intricate microbial interactions in the environment is crucial.

Wild relatives of potato (Solanum L. sec. Petota) poorly sampled and unprotected in Colombia
Crop Science, Volume 64, Issue 1, Page 225-243, January/February 2024.Abstract Wild potato relatives (Solanum L. sec. Petota) play a vital role in crop improvement, understanding crop evolution, and conserving potato diversity. However, these invaluable resources are often neglected and underutilized and are susceptible to threats such as climate change, urbanization, and agricultural expansion. Little is known about the
