In Arabidopsis thaliana, the bHLH transcription factor, GLABRA3 (AtGL3), is an important regulator of epidermal cell differentiation and positively controls anthocyanin accumulation. In contrast, we previously showed that Solanum lycopersicum GLABRA3 (SlGL3), the AtGL3 homolog, suppressed
Insertion of reporter genes into plant virus genomes is a common experimental strategy to research many aspects of the viral infection dynamics. Their numerous advantages make fluorescent proteins the markers of choice in most studies. However, the use of fluorescent proteins still has some
Red pap1-D cells of Arabidopsis thaliana have been cloned from production of anthocyanin pigmentation 1-Dominant (pap1-D) plants. The red cells are metabolically programmed to produce high levels of anthocyanins by a WD40-bHLH-MYB complex that is composed of the TTG1, TT8/GL3 and PAP1 transcription
Artemisia annua is an important medicinal plant producing the majority of the antimalarial compound artemisinin. Jasmonates are potent inducers of artemisinin accumulation in Artemisisa annua plants. As the receptor of jasmonates, the F-box protein COI1 is critical to the JA signaling required for
In this study, a novel plant growth-promoting rhizobacteria (PGPR), the bacterial strain Paenibacillus pabuli P7S (PP7S), showed promising plant growth-promoting effects. Furthermore, it induced anthocyanin accumulation in Arabidopsis. When co-cultivated with PP7S, there was a significant increase
The major anthocyanin in the leaves and stems of Arabidopsis thaliana has been isolated and shown to be cyanidin 3-O-[2-O(2-O-(sinapoyl)-beta-D-xylopyranosyl)-6-O-(4-O-(beta-D-glucopyranosyl)-p-coumaroyl-beta-D-glucopyranoside] 5-O-[6-O-(malonyl) beta-D-glucopyranoside]. This anthocyanin is a
Anthocyanins are secondary plant metabolites ubiquitous in the plant kingdom. They have different biological activities, so monitoring their content in plant tissue or in feed/food derived from plants may be an important task in different projects from various fields of molecular biology and
At present, research on the flower color of Rosa rugosa requires very innovative and practical studies. Glycosylation plays an important role in increasing the stability and solubility of anthocyanins in plants. In this study, a gene with a full-length cDNA of 1161 bp encoding 386 amino acids,
Floral pigmentation is of major importance to the ornamental industry, which is constantly searching for cultivars with novel colors. Goldenrod (Solidago canadensis) has monochromatic yellow carotenoid-containing flowers that cannot be modified using classical breeding approaches due to a
When plants are exposed to stress conditions, irreversible damage can occur, negatively impacting yields. It is therefore important to detect stress symptoms in plants, such as the accumulation of anthocyanin, as early as possible.
Light is an important environmental factor affecting plant growth and development. Additionally, HY5 is a central factor that coordinates light signal transduction and regulates the expression of flower color-related genes. However, there are few reports describing the co-regulation of apple fruit
In Arabidopsis thaliana, the R3-type MYB transcription factor CAPRICE (CPC) and bHLH transcription factor GLABRA3 (GL3) cooperatively regulate epidermal cell differentiation. CPC and GL3 are involved in root-hair differentiation, trichome initiation and anthocyanin biosynthesis in Arabidopsis
Transcriptional activation of anthocyanin biosynthesis genes in vegetative tissues of monocotyledonous plants is mediated by cooperative activity of one component from each of the following two transcription factor families: MYB encoded by PURPLE PLANT1/COLORED ALEURONE1 (PL1/C1), and basic
Previous studies have shown that GLABRA3 (AtGL3), a bHLH transcription factor, plays essential roles in anthocyanin biosynthesis and trichome formation in Arabidopsis thaliana. However, there have been no such studies of a homologue, BnGL3, from the closely related crop, Brassica napus. Here, we
Comprehensive research in various plants shows that the metabolic pathway of anthocyanin biosynthesis is affected by environmental factors and regulated by microRNAs through post-transcriptional regulation. In seedlings of Brassica rapa Tsuda, the accumulation of anthocyanin is induced by
