Metabolomic and Single‐Cell Transcriptomic Analyses Shed Light on Secondary Metabolite Profiling and Potential Developmental Dynamics of Glandular Trichomes in Artemisia argyi

Plant Biotechnology Journal, EarlyView.
ABSTRACT Plant glandular trichomes (GTs) are characterised by their ability to synthesise and store abundant secondary metabolites of significant biological importance. The medicinal plant Artemisia argyi exhibits a dense covering of GTs, yet the precise metabolic compositions and the developmental molecular dynamics of A.

The Diversity of the DNA‐Binding Landscape in the DREB/ERF Family: Focusing on Reproductive Processes in Fruit Trees With Highly Heterozygous Genome

Plant Biotechnology Journal, EarlyView.
ABSTRACT DREB/ERF transcription factors play pivotal roles in plant development; however, their structural characteristics, DNA‐binding preferences, and functional roles in highly heterozygous woody plants remain insufficiently understood. Using lychee (Litchi chinensis) as a model, we identified 95 DREB/ERF genes subdivided into ten phylogenetic ...

The Volatile Pentadecane From Bacillus Alleviates Plant Iron Deficiency Through Activating the Reduction‐Based Fe Uptake System

Plant Biotechnology Journal, EarlyView.
ABSTRACT Iron (Fe) is an essential micronutrient for plant growth and development. Rhizosphere microorganisms play crucial roles in plant Fe nutrition, yet the underlying mechanisms remain largely unknown. Here, we assessed the effect of the volatile organic compounds (VOCs) produced by Bacillus velezensis SQR9 on Fe uptake in Arabidopsis, elucidated ...

Deep Eutectic Solvent-Based Microextraction of Lead(II) Traces from Water and Aqueous Extracts before FAAS Measurements

Molecules, 2020
Microextraction procedures for the separation of Pb(II) from water and food samples extracts were developed. A deep eutectic solvent composed of α-benzoin oxime and iron(III) chloride dissolved in phenol was applied as a phase separator support.

Determination of the chemical composition of tea by chromatographic methods: a review [PDF]

, 2015
Despite the fact that mankind has been drinking tea for more than 5000 years, its chemical composition has been studied only in recent decades. These studies are primarily carried out using chromatographic methods.
