Structural analysis of the NifL‐NifA complex reveals the molecular basis of anti‐activation of nitrogen fixation gene expression in Azotobacter vinelandii

The FEBS Journal, EarlyView.
Using cryo‐EM combined with biochemical and genetic approaches, we mapped the interaction surface between NifL and NifA to gain insights into the regulation of nitrogen fixation genes in A. vinelandii. Our findings suggest that NifL, a homolog of histidine kinases lacking phosphorylation activity, evolved to act as a steric block of NifA activity ...

GeARF5/GeIAA33‐GeSWEET14 module balances the secondary metabolic biosynthesis to increase the yield and quality in Gastrodia elata

Journal of Integrative Plant Biology, EarlyView.
Auxin signaling regulates the formation of vegetative propagation corms in Gastrodia elata by regulating sugar‐acid interconversion, which in turn regulates polysaccharide and starch biosynthesis as well as biosynthesis of the bioactive metabolite gastrodin.

Preference and In Vitro Digestibility of Leaves of Woody Plants by Sheep in the Northern Sudanian Zone

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT In West Africa, trees and shrubs are important for feeding ruminant livestock during the dry season. This study aimed to determine the in vitro digestibility of organic matter from eight woody species using a gas test with and without the addition of polyethylene glycol (PEG), and evaluate their preference by sheep using a cafeteria test ...

Differentially Expressed Salivary miRNAs in Temporomandibular Disorders

Orthodontics &Craniofacial Research, EarlyView.
ABSTRACT Objective Temporomandibular disorders (TMDs) are heterogeneous conditions of unclear aetiology involving the temporomandibular joint, masticatory muscles and neural tissues. Limited understanding of their pathogenesis hampers accurate diagnosis and targeted treatment. Therefore, this study aimed to identify salivary microRNA (miRNA) signatures
