CsMYB1 integrates the regulation of trichome development and catechins biosynthesis in tea plant domestication

New Phytologist, Год журнала: 2022, Номер 234(3), С. 902 - 917

Опубликована: Фев. 15, 2022

Summary Tea trichomes synthesize numerous specialized metabolites to protect plants from environmental stresses and contribute tea flavours, but little is known about the regulation of trichome development. Here, we showed that CsMYB1 involved in formation galloylated cis ‐catechins biosynthesis plants. The variations expression levels are closely correlated with indexes contents plant populations. Genome resequencing may be selected modern cultivars, since a 192‐bp insertion promoter was found exclusively cultivars not glabrous wild Camellia taliensis . Several enhancers increased transcription coincided their higher indexes. Biochemical analyses transgenic data interacted CsGL3 CsWD40 formed MYB‐bHLH‐WD40 (MBW) transcriptional complex activate regulator genes CsGL2 CsCPC , anthocyanidin reductase serine carboxypeptidase‐like 1A integratively regulated biosynthesis. Results suggest coincidently during domestication by harsh environments for improved adaption breeders better flavours.

Root microbiota of tea plants regulate nitrogen homeostasis and theanine synthesis to influence tea quality

Current Biology, Год журнала: 2024, Номер 34(4), С. 868 - 880.e6

Опубликована: Фев. 1, 2024

The flavor profile of tea is influenced not only by different varieties but also the surrounding soil environment. Recent studies have indicated regulatory role microbes residing in plant roots nutrient uptake and metabolism. However, impact this mechanism on quality remains unclear. In study, we showed that a consortium isolated from enhanced ammonia facilitated synthesis theanine, key determinant taste. Variations were observed composition microbial populations colonizing rhizosphere across seasons varieties. By comparing root microorganisms high-theanine variety Rougui with low-theanine Maoxie, identified specific group potentially modulate nitrogen metabolism, subsequently influencing theanine levels tea. Furthermore, constructed synthetic community (SynCom) mirroring microbe population found roots. Remarkably, applying SynCom resulted significant increase content plants imparted greater tolerance to deficiency Arabidopsis. Our study provides compelling evidence supporting use as functional fertilizers enhance quality.

How does tea (Camellia sinensis) produce specialized metabolites which determine its unique quality and function: a review

Critical Reviews in Food Science and Nutrition, Год журнала: 2021, Номер 62(14), С. 3751 - 3767

Опубликована: Янв. 6, 2021

Tea (Camellia sinensis) is both a plant and foodstuff. Many bioactive compounds, which are present in the final tea product related to its quality or functional properties, produced during manufacturing process. However, characteristic secondary metabolites, give unique qualities beneficial human health, mainly leaves process of growth. Therefore, it important understand how produce these specialized metabolites. In this review, we first compare common metabolites tea, coffee, cocoa, grape discuss occurrence tea. Progress research into formation summarized, including establishing biological database genetic transformation system, biosynthesis Finally, speculation on future provided from viewpoints origin, resources, cultivation, processing This review provides an reference for terms characteristics.

Plant pan-genomics: recent advances, new challenges, and roads ahead

Journal of genetics and genomics/Journal of Genetics and Genomics, Год журнала: 2022, Номер 49(9), С. 833 - 846

Опубликована: Июнь 21, 2022

Pan-genomics can encompass most of the genetic diversity a species or population and has proved to be powerful tool for studying genomic evolution origin domestication species, providing information plant improvement. Plant genomics greatly progressed because improvements in sequencing technologies rapid reduction costs. Nevertheless, pan-genomics still presents many challenges, including computationally intensive assembly methods, high costs with large numbers samples, ineffective integration big data, difficulty applying it downstream multi-omics analysis breeding research. In this review, we summarize definition recent achievements pan-genomics, computational used pan-genome construction, applications pan-genomes molecular breeding. We also discuss challenges perspectives future studies provide detailed pipeline sample selection, genome annotation, structural variation identification, construction application graph-based pan-genomes. The aim is important guidance research better understanding basis evolution, crop domestication, phenotypic studies.

Fu Brick Tea Manages HFD/STZ-Induced Type 2 Diabetes by Regulating the Gut Microbiota and Activating the IRS1/PI3K/Akt Signaling Pathway

Journal of Agricultural and Food Chemistry, Год журнала: 2022, Номер 70(27), С. 8274 - 8287

Опубликована: Июнь 29, 2022

The antidiabetic effects of Fu brick tea aqueous extract (FTE) and its underlying molecular mechanism in type 2 diabetes mellitus (T2DM) mice were investigated. FTE treatment significantly relieved dyslipidemia, insulin resistance (IR), hepatic oxidative stress caused by T2DM. also ameliorated the T2DM-induced gut dysbiosis decreasing Firmicutes/Bacteroidota (F/B) ratio at phylum level promoting proliferation Bifidobacterium, Parabacteroides, Roseburia genus level. Besides, improved colonic short-chain fatty acid levels T2DM mice. Furthermore, proved to be mediated IRS1/PI3K/Akt AMPK-mediated gluconeogenesis signaling pathways. Metabolomics analysis illustrated that recovered 28 metabolites associated with normal Taken together, these findings suggest can alleviate reshaping microbiota, activating pathway, regulating intestinal metabolites.

Study on the correlation between color and taste of beauty tea infusion and the pivotal contributing compounds based on UV–visible spectroscopy, taste equivalent quantification and metabolite analysis

Food Chemistry X, Год журнала: 2024, Номер 21, С. 101192 - 101192

Опубликована: Фев. 5, 2024

This study utilized a colorimeter to determine the color values of 23 beauty tea (BT) samples, and taste characteristics were also quantitatively described through ultraviolet–visible (UV–Vis) spectroscopy equivalent quantification. Furthermore, metabolomic analysis was conducted by using ultra-high-performance liquid chromatography-mass spectrometry (UPLC-MS). Correlation employed preliminarily identify compounds that contribute BT infusion. Finally, contributing further determined verification experiment. The results showed within certain range, as infusion deepened, became stronger, more bitter astringent, while on contrary, it sweeter mellower. Theaflavins, kaempferol, astragalin, 5-p-coumaroylquinic acid influenced both Gallic contributor color. provides new insights into research quality in aspects.
