The HD‐GYP domain of RpfG mediates a direct linkage between the Rpf quorum‐sensing pathway and a subset of diguanylate cyclase proteins in the phytopathogen Xanthomonas axonopodis pv citri [PDF]

Molecular Microbiology, 2006
SummaryBacteria use extracellular levels of small diffusible autoinducers to estimate local cell‐density (quorum‐sensing) and to regulate complex physiological processes. The quorum‐sensing signal transduction pathway of Xanthomonas spp. phytopathogens has special features that distinguish it from that of other pathogens. This pathway consists of RpfF,

TolC Is Required for a Mixed‐Linkage β‐Glucan (MLG) Biosynthesis: Engineering Bacteria for MLG Overproduction

Microbial Biotechnology, Volume 19, Issue 8, August 2026.
TolC is identified as an essential component of the mixed‐linkage β‐glucan (MLG) biosynthetic machinery in Sinorhizobium meliloti, likely enabling polymer export. Co‐expression of tolC, bgsBA, and pleD* significantly enhances MLG production and enables its synthesis in non‐native bacterial hosts.

Active Site Metal Occupancy and Cyclic Di-GMP Phosphodiesterase Activity of Thermotoga maritima HD-GYP

, 2016
HD-GYPs make up a subclass of the metal-dependent HD phosphohydrolase superfamily and catalyze conversion of cyclic di­(3′,5′)-guanosine monophosphate (c-di-GMP) to 5′-phosphoguanylyl-(3′→5′)-guanosine (pGpG) and GMP. Until now, the only reported crystal

Population Status and Habitat Preferences of the Critically Endangered African White‐Backed Vulture (Gyps africanus) in Southwest Ethiopia Region

Ecology and Evolution, Volume 16, Issue 7, July 2026.
The critically endangered African white‐backed Vulture is declining rapidly across Africa due to anthropogenic threats. This study, conducted in southwest Ethiopia, quantifies its population status and reveals key habitat preferences across breeding and foraging sites. The findings provide essential data for crafting targeted conservation strategies to

The MarR Family Transcriptional Regulator EmrR Negatively Regulates the Type III Secretion System (T3SS) and Positively Modulates Pathogenicity in Dickeya oryzae

Molecular Plant Pathology, Volume 27, Issue 4, April 2026.
This study revealed that the transcriptional regulator EmrR in Dickeya oryzae modulates virulence by regulating hrpL expression and c‐di‐GMP levels. It affects motility, biofilm formation, cellulase production and pathogenicity. EMSA and footprinting confirmed EmrR binds directly to the promoter of its target operon.

Wellbore Gyp-Scale Control

, 1975
Gyp-scale deposition in producing wellbores is a recognized problem in many West Texas oil fields. The results of gyp-scale formation are usually reduced producing rates, premature well abandonment, and high operating expenses.

Effect of Fish Meal Replacement by Complex Protein on Growth Performance, Metabolism, and Health of Triploid Rainbow Trout (Oncorhynchus mykiss)

Aquaculture Nutrition, Volume 2026, Issue 1, 2026.
A comprehensive investigation was conducted to evaluate dietary fish meal (FM) replacement by a complex protein blend composed of soybean meal, soybean protein concentrate, corn gluten meal, wheat gluten, and blood cell powder in triploid rainbow trout (Oncorhynchus mykiss). Five isonitrogenous (46% crude protein) and isolipidic (24% crude lipid) diets
