Phenotypic plasticity of nest-mate recognition cues in formica exsecta ants [PDF]

, 2019
It is well established that many ant species have evolved qualitatively distinct species-specific chemical profile that are stable overlarge geographical distances.

The BAHD Acyltransferase Gene Family: Evolutionary Dynamics, Biochemical Mechanisms, and Roles in Plant Stress Adaptation

Plant Biotechnology Journal, EarlyView.
BAHD acyltransferases drive metabolic diversification in plants by coupling conserved catalytic scaffolds with regulatory flexibility, enabling stress adaptation and ecological specialisation. ABSTRACT BAHD acyltransferases constitute one of the most versatile enzyme superfamilies in plants, catalysing the acylation of alcohols, amines, polyamines, and

Actinomycetospora chiangmaiensis gen. nov., sp. nov., a new member of the family Pseudonocardiaceae [PDF]

, 2008
A novel actinonmycete strain, YIM 0006(T), was isolated from soil of a tropical rainforest in northern Thailand. The isolate displayed the following characteristics: aerial mycelium is absent, short spore chains are formed directly on the substrate ...

Structural Elucidation and Engineering of the (S)‐scoulerine 2‐O‐Methyltransferase Enabling Regioselective Epiberberine Biosynthesis in Coptis chinensis

Plant Biotechnology Journal, EarlyView.
ABSTRACT Protoberberine alkaloids are a characteristic group of natural products in Coptis plants known for their notable pharmacological activities. However, the structural similarity and the substrate promiscuity of their biosynthetic enzymes have left the precise synthetic pathways remain unclarified, posing challenges to regulate product formation.

Williamsia faeni sp. nov., an actinomycete isolated from a hay meadow [PDF]

, 2010
The taxonomic status of an actinomycete isolated from soil collected from a hay meadow was determined using a polyphasic approach. The strain, designated N1350T, had morphological and chemotaxonomic properties consistent with its classification in the ...

Transcriptional Regulation of the Novel Theacrine Synthase Gene CsTcS2 by the CsTINY–CsWRKY33 Module Underpins Theacrine Biosynthesis in Camellia sinensis

Plant Biotechnology Journal, EarlyView.
ABSTRACT Theacrine (1,3,7,9‐tetramethyluric acid) is a purine alkaloid detected in multiple wild and specialised tea germplasms (Camellia sinensis) from South China, including Kucha. However, the molecular mechanisms governing its biosynthesis remain poorly understood. Here, we identify CsTcS2 as a novel theacrine synthase in tea plant.

Análise e discriminação de quimiotipos de Lippia graveolens H.B.K. da Guatemala por microextração em fase sólida, CG-EM e análise multivariada

Química Nova, 2012
SPME-GC-MS, PCA and HCA multivariate techniques were used in order to evaluate their applicability to discriminate the three chemotypes (thymol, carvacrol and mixed) described for L. graveolens of Guatemala. The leaves of L.

Transcriptome and Hormone Regulations Shape Drought Stress‐Dependent Fusarium Head Blight Susceptibility in Different Barley Genotypes

Plant, Cell &Environment, EarlyView.
ABSTRACT Little is known about regulatory mechanisms that crop plants use to respond to combinations of abiotic and biotic stress. We analysed four barley genotypes under simultaneous Fusarium culmorum infection and drought stress by phenotyping for Fusarium Head Blight (FHB) disease, drought stress responses, hormone profiling and transcriptome ...

Response of Melissa officinalis subsp. officinalis seedlings to Fe3O4‐NPs under in vitro conditions: physiological, biochemical and molecular analyses

Plant Biology, EarlyView.
Iron oxide nanoparticles influence the growth, antioxidant capacity, and gene activity of Melissa officinalis subsp. officinalis plants in vitro, revealing their potential as modulators of secondary metabolism. Abstract Application of iron oxide nanoparticles (NP) (Fe3O4‐NPs) in plant biotechnology presents new opportunities for enhancing metabolic ...
