Optimizing isotopic measurement of potential free‐living nitrogen fixation in soil

Soil Science Society of America Journal, Volume 89, Issue 6, November/December 2025.
Abstract Direct measurements of free‐living nitrogen fixation (FLNF) using 15N‐labeled dinitrogen (15N2) have been complicated by a lack of standardization regarding soil sampling and storage, and because key incubation parameters have yet to be systematically optimized. With the aim of developing a standardized protocol for laboratory assay of carbon (

Photosynthetic and Growth Responses of Arundo donax L. Plantlets Under Different Oxygen Deficiency Stresses and Reoxygenation

Frontiers in Plant Science, 2019
Promotion of nonfood species production to marginal, degraded lands abandoned by mainstream agriculture is affected by extremes of water availability (droughts and floods), which have increased in frequency and intensity and account for severe yield ...

Modeling the influence of rhizodeposits on root water uptake

Vadose Zone Journal, Volume 24, Issue 6, November/December 2025.
Abstract The chemical compounds that plant roots release into the soil, referred to as rhizodeposits, affect soil hydraulic properties like the surface tension and viscosity of soil water, and the contact angle between menisci and the pore surface.

Bacterial membrane vesicles restore gut anaerobiosis

npj Biofilms and Microbiomes
Inflammation damages the epithelial cell barrier, allowing oxygen to leak into the lumen of the gut. Respiring E. coli and other Enterobacteriaceae produce proinflammatory lipopolysaccharide, exacerbating inflammatory bowel disease. Here we show that respiring membrane vesicles (MV) from E. coli ameliorate symptoms in a mouse model of gut inflammation.

Bacillus cereus Fnr binds a [4Fe-4S] cluster and forms a ternary complex with ResD and PlcR

BMC Microbiology, 2012
Background Bacillus cereus is a facultative anaerobe that causes diarrheal disease in humans. Diarrheal syndrome may result from the secretion of various virulence factors including hemolysin BL and nonhemolytic enterotoxin Nhe.

Effects of Anoxia on Amino Acid Levels in Rice Coleoptiles

Plant Production Science, 2006
Effects of anoxia on the levels of free-amino acids were investigated in the coleoptiles of rice (Oryza sativa L.) seedlings. Rice coleoptiles are able to grow in extremely low oxygen conditions.
