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

Intermolecular interactions between HD-GYP and GGDEF domain proteins mediate virulence-related signal transduction in Xanthomonas campestris

, 2010
In the plant pathogen Xanthomonas campestris pv. campestris (Xcc) a two component system comprising RpfG and the complex sensor kinase RpfC is implicated in sensing and responding to the cell-cell signaling molecule DSF to positively regulate the ...

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.

HD-GYP domain proteins regulate biofilm formation and virulence in Pseudomonas aeruginosa

, 2009
HD-GYP is a protein domain involved in the hydrolysis of the bacterial second messenger cyclic-di-GMP. The genome of the human pathogen Pseudomonas aeruginosa PAO1 encodes two proteins (PA4108, PA4781) with an HD-GYP domain and a third protein, PA2572 ...

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

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

The Diverse Roles of the Histone‐Like Nucleoid Structuring (H‐NS) Protein in Vibrio parahaemolyticus

Genetics Research , Volume 2026, Issue 1, 2026.
The histone‐like nucleoid structuring (H‐NS) protein is a global transcriptional regulator critical for bacterial genome organization and gene expression. In Vibrio parahaemolyticus, H‐NS represses virulence factors such as thermostable direct hemolysin (TDH), type III secretion systems (T3SS1/T3SS2), and type VI secretion systems (T6SS1/T6SS2).

A GGDEF and EAL domain-containing protein in Pseudomonas syringae pv. actinidiae regulates virulence via its diguanylate cyclase activity

Phytopathology Research
Kiwifruit bacterial canker (KBC), caused by Pseudomonas syringae pv. actinidiae (Psa), poses a severe threat to the global kiwifruit industry, highlighting the urgent need to elucidate its pathogenic mechanisms. Cyclic diguanylate monophosphate (c-di-GMP)
