Harnessing the synergy of Urochloa brizantha and Amazonian Dark Earth microbiomes for enhanced pasture recovery.
BMC Microbiol
January 2025
Center for Nuclear Energy in Agriculture, University of São Paulo, Piracicaba, SP, Brazil.
Amazonian Dark Earths (ADEs) are fertile soils from the Amazon rainforest that harbor microorganisms with biotechnological potential. This study aimed to investigate the individual and potential synergistic effects of a 2% portion of ADEs and Urochloa brizantha cv. Marandu roots (Brazil's most common grass species used for pastures) on soil prokaryotic communities and overall soil attributes in degraded soil.

During early mammalian development, the endoderm germ layer forms the foundation of the respiratory and digestive systems through complex patterning. This intricate process, guided by a series of cell fate decisions, remains only partially understood. Our study introduces innovative genetic tracing codes for 14 distinct endodermal regions using novel mouse strains.

In integrated crop-livestock systems, livestock graze on cover crops and deposit raw manure onto fields to improve soil health and fertility. However, enteric pathogens shed by grazing animals may be associated with foodborne pathogen contamination of produce influenced by fecal-soil microbial interactions. We analyzed 300 fecal samples (148 from sheep and 152 from goats) and 415 soil samples (272 from California and 143 from Minnesota) to investigate the effects of grazing and the presence of non-O157 Shiga toxin-producing Escherichia coli (STEC) or generic E.

Leydig cells produce hormones that are required for male development, fertility, and health. Two Leydig cell populations produce these hormones but at different times during development: fetal Leydig cells which are active during fetal life and adult Leydig cells that are functional postnatally. Historically, our ability to understand the origin and function of Leydig cells has been made difficult by the lack of genetic models to exclusively target these cells.

Objectives: Acetylated tubulin is a hallmark of flagellar stability in spermatozoa, and studies have demonstrated the ability of CDYL to function as a tubulin acetyltransferase in spermatozoa. Of note, germline conditional knockout of Cdyl can lead to asthenoteratozoospermia and infertility in male mice. However, the role of CDYL gene in human fertility remains uncharacterized.
