Flavonoids are major secondary metabolites in Camellia sinensis. Flavanone-3-hydroxylase (F3H) is a key enzyme in flavonoid biosynthesis in plants. However, its role in the flavonoid metabolism in C. sinensis has not been well studied. In this study, we cloned two F3Hs from C. sinensis, named CsF3Ha and CsF3Hb, where CsF3Ha containing 1107 bases encoded 368 amino acids, and CsF3Hb containing 10...

Phloem-feeding aphids cause serious damage to plants. The mechanisms of plant-aphid interactions are only partially understood and involve multiple pathways, including phytohormones. In order to investigate whether salicylic acid (SA) is involved and how it plays a part in the defense response to the aphid Macrosiphoniella sanbourni, physiological changes and gene expression profiles in respons...

Genetic modification of secondary metabolic pathways to produce desirable natural products is an attractive approach in plant biotechnology. In our study, we attempted to produce a typical soybean isoflavone genistein, a well-known health-promoting metabolite, in non-legume plants via genetic engineering. Both overexpression and antisense suppression strategies were used to manipulate the expre...

Mulberry fruits are rich in anthocyanins, which important secondary metabolites that give mulberries their bright color, favorable taste and high nutritional quality, making them a popular fruit. However, few studies have focused on the molecular mechanism underlying anthocyanin accumulation gene regulatory networks of biosynthetic pathways remain largely unknown. In this study, we performed RN...

Although a great deal of progress has been made toward understanding the role of abscisic acid (ABA) in fruit ripening, many components in the ABA signalling pathway remain to be elucidated. Here, a strawberry gene homologous to the Arabidopsis gene ABI1, named FaABI1, was isolated and characterized. The 1641bp cDNA includes an intact open reading frame that encodes a deduced protein of 546 ami...

Anthocyanins are important compounds for red grape and red wine quality, and can be influenced by supply of nutrients such as nitrogen, phosphorus, potassium, zinc, and iron. The present work aims to gain a better understanding of the effect of iron supply on anthocyanins concentration in grape berries. To this end, own-rooted four-year-old Cabernet Sauvignon grapevines (Vitis vinifera) were fe...

The purpose of this study is to reveal the structure and function leucoanthocyanidin dioxygenase ( LDOX ) gene in Actinidia arguta . Bioinformatics methods were used analyze nucleotide amino acid sequences , construct protein interaction network gene, conduct GO KEGG functional annotation analysis. results showed that there 10 conserved motifs which was closely related Vaccinium corymbosum Loni...

Radix astragali, from the roots of Astragalus L. species, is regarded as an important traditional medicinal plant and has been widely used a Qi-Invigorating medicine for more than 2 000 years. Considering different metabolites or functional compounds astragali distinct underlying genetic information among two species important. Here, we compared root transcriptomes expression patterns genes inv...

The grape berries due to containing organic acids, sugars, aromatic compounds, phenolic compounds (including anthocyanins, flavanols, flavonols, stilbenes (resveratrol)), tannins, and oil in the pulp, skin, and seed have numerous health benefits for human health. In this study, we investigated genetic and phytochemical characteristics of four famous grapevine cultivars (Shiraz, Sirch, Panje Aro...

Abstract Acer rubrum L., a widely used ornamental colored-leaf tree species, has great utility in both residential and urban landscaping. However, unsuitable environmental conditions tend to reduce the intensity of color change, greatly reducing value this species. Here, we investigated discoloration A. leaves from red green during maturation. We first quantified leaf-color change L * , b space...
