A Deep Metagenomic Snapshot as a Proof‐of‐Concept for Resource Generation: Simultaneous Assembly of Host, Food, and Microbiome Genomes From Stingless Bee Larval Food

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
This study serves as a proof‐of‐concept, demonstrating that deep shotgun sequencing of a single complex sample—stingless bee larval food—can simultaneously generate multiple genomic resources. From this dataset, we assembled three genomes (a near‐complete bacterium, a draft host mitochondrion, and a fragmented plant chloroplast) with varying ...

Off‐season crops as a strategy for renovating degraded pastures and improving maize yield in a low‐altitude tropical region

open access: yesAgronomy Journal, Volume 117, Issue 6, November/December 2025.
Abstract Brazil can expand cultivated areas without deforestation by restoring degraded pastures and optimizing grain production through off‐season crops. This study evaluated eight off‐season treatments, including fallow, monocrops, and intercropping combinations, and their effects on maize (Zea mays L.) intercropped with guinea grass (Megathyrsus ...

Genetic system of two rainy season weeds: Commelina benghalensis L. and Commelina caroliniana Walter

open access: yesChromosome Botany, 2007
Commelina benghalensis L and C. caroliniana Walter, two allied weedy species of the Commelinaceae vary in their breeding and meiotic systems. The former is predominantly auto- and the latter facultatively xenogamous. Meiotic system of C. caroliniana also provides for higher recombination index, characterized as it is by high chromosome number and ...
