A yeast model of 5‐oxoproline accumulation reveals a general toleration to 5‐oxoproline

FEBS Open Bio, EarlyView.
Using a yeast model, we show that even high accumulation of 5‐oxoproline causes only mild cellular stress and does not trigger oxidative stress. Instead, cells adapt by activating efflux pumps and diverse protective pathways, suggesting that previously proposed harmful effects of 5‐oxoproline may arise from indirect metabolic imbalances rather than the

Significant impact of Bacillus licheniformis DW4, Salinicoccus sesuvii DW5 and Paenalcaligenes suwonensis DW7, in mitigation of seawater stress on the growth and productivity of Vicia Faba cultivated in Qalabshu semi-field soil

BMC Plant Biology
Background Salinity severely limits sensitive crops like Vicia faba in newly-reclaimed lands. Costly mitigation is unsustainable; Plant Growth-Promoting Bacteria (PGPB) from halophytes provide a cheap, effective, eco-friendly solution to alleviate salt ...

Lipopolysaccharide uptake is augmented in lipopolysaccharide‐tolerant mouse macrophage‐like cells via increased CD14 expression

FEBS Open Bio, EarlyView.
In normal (nontolerant) cells, CD14 is crucial for both LPS uptake and LPS signaling. In LPS‐tolerant cells, in which LPS‐induced TNF‐α and IFN‐β production is suppressed, there is a dramatic increase in surface CD14 expression. The overexpressed CD14 in LPS‐tolerant cells is responsible for the enhanced LPS uptake without inducing pro‐inflammatory ...

How phagocytic cells kill bacteria: Lessons from a professional killer

FEBS Open Bio, EarlyView.
How phagocytic cells ingest and kill bacteria has been studied for more than a century, but many questions remain unanswered. The study of the amoeba Dictyostelium discoideum brings new answers, and new questions. Professional phagocytic cells such as neutrophils and macrophages, as well as free‐living soil amoebae like Dictyostelium discoideum, employ

Long-Term Effects of Plastic Mulch in a Sandy Loam Soil Used to Cultivate Blueberry in Southern Portugal

Pollutants
Numerous plastic products are used in agriculture, including containers, packaging, tunnels, drip irrigation tubing, and mulches. Large amounts of plastics are used as mulches on the soil surface for vegetable and fruit production (tomato, cucumber ...

Nitrogênio, carbono e atividade da biomassa microbiana do solo em plantações de eucalipto Carbon, nitrogen and activity of microbial biomass in soil under eucalypt plantations

Revista Brasileira de Ciência do Solo, 2005
Grande parte das plantações de eucalipto no Brasil situa-se em solos de baixa fertilidade, para os quais a técnica de fertilização e o processo de ciclagem de nutrientes são fundamentais para elevar e manter a produção florestal.

Avidin is evolutionarily conserved in fish but dispensable for development and resistance against Streptococcus agalactiae in zebrafish

FEBS Open Bio, EarlyView.
The presence of biotin‐binding avidin proteins in fish and their biological significance are poorly characterized. We cataloged fish avidins and demonstrate that they are widely present and evolutionarily conserved. We created avd knockout zebrafish and show that zebavidin is dispensable for development and that resistance of avd knockout embryos in ...

Mineralização do carbono da palha de aveia e dejetos de suínos aplicados na superfície ou incorporados ao solo Carbon mineralization of straw and pig manure with and without incorporation in soil

Revista Brasileira de Ciência do Solo, 2008
A mineralização do C de dejetos de suínos e de palhas de cereais é um processo ainda relativamente pouco estudado no Brasil. O objetivo deste trabalho foi avaliar a mineralização do C da palha de aveia, dos dejetos líquidos de suínos e da cama sobreposta
