Decoding the complete organelle genomic architecture of Stewartia gemmata: an early-diverging species in Theaceae.

Background: Theaceae, comprising 300 + species, holds significance in biodiversity, economics, and culture, notably including the globally consumed tea plant. Stewartia gemmata, a species of the earliest diverging tribe Stewartieae, is critical to offer insights into Theaceae's origin and evolutionary history.

Result: We sequenced the complete organelle genomes of Stewartia gemmata using short/long reads sequencing technologies.

Effects of Lactic Acid Bacteria Fermentation on the Physicochemical Properties of Rice Flour and Rice Starch and on the Anti-Staling of Rice Bread.

In this study, subspecies 1.2472, 1.2718, and thermostable HCUL 1.

Transcriptome-based variations effectively untangling the intraspecific relationships and selection signals in Xinyang Maojian tea population.

As one of the world's top three popular non-alcoholic beverages, tea is economically and culturally valuable. Xinyang Maojian, this elegant green tea, is one of the top ten famous tea in China and has gained prominence for thousands of years. However, the cultivation history of Xinyang Maojian tea population and selection signals of differentiation from the other major variety var.

Phylogenomics Resolves the Phylogeny of Theaceae by Using Low-Copy and Multi-Copy Nuclear Gene Makers and Uncovers a Fast Radiation Event Contributing to Tea Plants Diversity.

Tea is one of the three most popular nonalcoholic beverages globally and has extremely high economic and cultural value. Currently, the classification, taxonomy, and evolutionary history of the tea family are largely elusive, including phylogeny, divergence, speciation, and diversity. For understanding the evolutionary history and dynamics of species diversity in Theaceae, a robust phylogenetic framework based on 1785 low-copy and 79,103 multi-copy nuclear genes from 91 tea plant genomes and transcriptome datasets had been reconstructed.

Microfluidic assay without blocking for rapid HIV screening and confirmation.

The essential step for HIV spreading limitation is the screening tests. However, there are multiple disadvantages in current screening assays which need further confirmation test. Herein we developed a rapid HIV assay combining screening and confirmation test by using the microfluidic network assay.

[β(2)-adrenoreceptor mediates the cardioprotection of ischemic preconditioning on myocardial contraction in rats subjected to ischemia/reperfusion injury].

The aim of the present study is to investigate the role of β(2)-adrenoreceptor (β(2)-AR) in ischemic preconditioning (IP) in isolated rat heart model of ischemia/reperfusion (I/R). Sprague-Dawley rat hearts were quickly removed, mounted on Langendorff apparatus, and perfused with Krebs-Henseleit (KH) solution. After the initial stabilization period, the rats were randomly divided into 6 groups including control group (perfused for an additional 20 min), IP group (4 cycles of 5 min of ischemia followed by 5 min of reflow), isoproterenol (ISO) group (10 nmol/L ISO perfusion for 5 min followed by 5 min washout), IP + ICI118551 group (55 nmol/L ICI118551 perfusion for 5 min before and throughout IP), ISO + ICI118551 group (55 nmol/L ICI118551 perfusion for 5 min before and throughout ISO treatment), ICI118551 group (55 nmol/L ICI118551 perfusion for 20 min).
