Litchi (Litchi chinensis Sonn.) is an important subtropical fruit in southern China and the fruit pericarp has attractive red skin at maturity, which is provided by anthocyanins accumulation. To understand the anthocyanin biosynthesis at post-transcriptional level, we investigated the roles of microRNAs (miRNAs) during fruit coloring. In the present study, four small RNA libraries and a mixed d...

Antllocyanin-rich crops have attracted attention in recent years because of their health benefits, and anthocyanin-rich tea is one of these crops. 'F95181' (Camellia sinensis) was developed for breeding anthosyanin-rich tea cultivars and registered as a new parental line 'Cha Chuukanbohon Nou 6' (C. sinensis) in 2004. 'F95181' was selected from an interspecific cross betweell C. taliensis (a wi...

Doxorubicin (Dox) is extensively used for chemotherapy in different types of cancer, but its use is limited to because of its cardiotoxicity. Our previous studies found that doxorubicin-induced insulin-like growth factor II receptor (IGF-IIR) accumulation causes cardiomyocytes apoptosis via down-regulation of HSF1 pathway. In these studies, we demonstrated a new mechanism through which anthocya...

Cultured plant cells are often highly heterogeneous in terms of secondary metabolite production. We have developed a quantitative determination method that uses an image processing system to estimate such individual cell characteristics as content of the secondary metabolite, anthocyanin. In this study, strawberry cells producing anthocyanins were grown in modified Linsmaier-Skoog medium. Antho...

In a previous paper (7), the advantages of corn endosperm tissue cultures as an experimental tool in attacking the problem of anthocyanin synthesis were pointed out. The general culture conditions, the identity of the pigments, and the requirement for light were reported in the same paper. Thimann and Radner (11, 12) have shown that anthocyanin synthesis in Spirodela is inhibited by -purine and...

Introduction The effects of various chemicals on anthocyanin synthesis and morphogenesis in the Impatiens hypocotyl were investigated to determine possible relationships between a specific biochemical process (anthocyanin synthesis) and morphogenetic events (the formation of roots and epidermal hairs). Cultured segments of balsam (Impatiens balsamina L.) provide excellent material for the study...

Plants exhibit a wide variety of disease symptoms in response to pathogen attack. In general, most plant symptoms are recognized as harmful effects on host plants, and little is known about positive aspects of symptoms for infected plants. Herein, we report the beneficial role of purple top symptoms, which are characteristic of phytoplasma-infected plants. First, by using plant mutants defectiv...

Streptomycin and chloramphenicol inhibit the development of the photosynthetic apparatus and enhance anthocyanin synthesis in tomato (Lycopersican esculentum, cv. Beefsteak) and red cabbage (Brassica oleracea, cv. Red Acre) seedlings. The two antibiotics do not affect the basic features of light-dependent anthocyanin formation: the relative effectiveness of different irradiance levels and of di...

Anthocyanins are a broad class of water soluble pigments found in a wide array of plants. They are responsible for a variety of the attractive colors found in fruits including red, purple, orange, and blue. There use as a natural alternative to synthetic colorants has been investigated extensively in the past several years as consumers have been asking for greater choice in the marketplace. The...

The present work evaluates the anthocyanin degradation in blueberry pulp after thermal treatment using ohmic and conventional heating. The ohmic heating technology was studied using a rotatable central composite design, and the variables studied were voltage and solids content. The anthocyanin content of the samples was determined using HPLC. The results show that degradation increased with bot...
