However, the precise molecular mechanisms by which BcWRKY33A governs root development remain elusive.

Aroma analysis and biomarker screening of 27 tea cultivars based on four leaf color types.

Green is no longer the only color used to describe tea leaves. As tea plants with different leaf colors-white, yellow, and purple-yield significant economic benefits, scholars are growing increasingly curious about whether these differently colored leaves possess unique aromatic characteristics. Headspace solid-phase microextraction (HS-SPME) combined with GC-MS was used to analyze the volatile metabolites of buds and leaves from 7 white-leaf tea plants, 9 yellow-leaf tea plants, 4 purple-leaf tea plants, and 7 normal (green) tea plants.

Multi-Omics analysis reveals the sensory quality and fungal communities of Tibetan teas produced by wet- and dry-piling fermentation.

Ya'an Tibetan tea, a dark tea with a rich historical heritage, is typically processed using two primary piling fermentation methods: wet piling with rolled leaves (moisture content around 60%) and dry piling with sun-dried or baked green tea leaves (moisture content below 30%). This study employed sensory evaluation, targeted and non-targeted metabolomics, and fungal Internal Transcribed Spacer (ITS) sequencing to investigate changes in quality components and fungal composition in Tibetan tea processed by both wet and dry-piling methods. The results revealed that 3,7-Dimethyl-1,5,7-octatriene-3-ol and D-limonene were identified as key volatile metabolites contributing to the aroma variations between the dry and wet-piled teas.

Peptide hormones in plants.

Peptide hormones are defined as small secreted polypeptide-based intercellular communication signal molecules. Such peptide hormones are encoded by nuclear genes, and often go through proteolytic processing of preproproteins and post-translational modifications. Most peptide hormones are secreted out of the cell to interact with membrane-associated receptors in neighboring cells, and subsequently activate signal transductions, leading to changes in gene expression and cellular responses.

Identification of an ethylene-responsive and cell wall-secreting β-1,3-glucanase, VvGLU1, in the early cell regrowth of grape winter buds triggered by exogenous dormancy releasers.

Background: Grape (Vitis vinifera) crops encounter significant challenges in overcoming bud endodormancy in warm winter areas worldwide. Research on the mechanisms governing bud dormancy release has focused primarily on stress regulation; however, cell wall regulation of bud meristem regrowth mechanism during the dormancy release remains obscure.

Results: In this study, transmission electron microscopy revealed significant changes in the grape bud cell wall following hydrogen cyanamide (HC) treatment, accompanied by an increase in β-1,3-glucanase activity.

Microspore culture is an efficient and rapid method that produces doubled haploid (DH) lines for hybrid breeding in crops and vegetables. However, the low frequency of microspore embryogenesis and spontaneous diploidization in Chinese kale still require improvement. In the present work, an efficient microspore culture protocol was constructed and used for DH producing in Chinese kale breeding.

The Interaction Between ABA and Sugar Signalling Regulates Stomatal Production in Systemic Leaves by Controlling Sucrose Transport.

A key feature of stress responses [closely relative to the phytohormone abscisic acid (ABA)] and associated acclimation in plants is the dynamic adjustments and related optimisation of carbohydrate content between sink and source organs. The production of stomata, which consist of a pore between two adjacent guard cells, are central to plant adaptation to changing environment conditions. In this context, ABA is a core modulator of environmentally determined stomatal development.
