Project description:We analyzed expression change of the genes which involved in anthocyanin and pro-anthocyanin biosynthesis to search an origin of black rice. The submitted samples were transcriptome data in black and red rice pericarps. Rice pericarps were harvested in 7 and 14 days after heading, respectively.

Project description:Colored-leaf plants are increasingly popular and have been attracting more and more attentions. However, studies about the anthocyanin components and molecular mechanisms of anthocyanin biosynthesis in QHP and ZSY was still unclear. In present study, an integrated metabolite and transcriptome profiling analysis was performed to explore the anthocyanin compositions and the specific regulatory network of anthocyanin biosynthesis in purple leaves of QHP and ZSY. A total of 39 anthocyanin compounds were detected based on the LC-MS/MS analysis. Of these, 12 cyanidins, 7 pelargonidins, 5 delphindins, and 5 procyanidins are the major anthocyanin compounds, which were significantly differentially accumulated in purple leaves of QHP and ZSY. The major genes associated with anthocyanin biosynthesis, including structural genes and TFs, were differentially expressed in the purple leaves of QHP and ZSY through RNA-seq data analysis, some of which were further assessed by qRT-PCR. Correlation between RNA-seq analysis and metabolite profiling showed that the expression pattern of some differentially expressed genes in anthocyanin biosynthes pathway were closely correlated with the differential accumulation of anthocyanins. In addition, one member of SG5 subgroup of R2R3-MYB TFs, Podel.04G021100, shows a similar expression pattern to some structure genes and closely correlates with sixteen anthocyanin compounds, indicating that the MBY TF (Podel.04G021100) may be involved in the regulation of anthocyanin biosynthesis. The above results not only make us systematic and comprehensive understand the anthocyanin components and corresponding molecular mechanisms of anthocyanin biosynthesis in purple leaves of QHP and ZSY, but also contribute to the promotion and application of anthocyanins in colored-leaf poplars.

Project description:MicroRNA172 (miR172) plays a role in regulating a diverse range of plant developmental processes. However, its role in regulating anthocyanin biosynthesis is unclear. In this study, we show that transgenic apple plants over-expressing miR172 show a reduction in red colouration and anthocyanin accumulation in multiple tissue types. This reduction was consistent with decreased expression of APETALA2 homolog MdAP2_1a (a miR172 target gene), MdMYB10, and targets of MdMYB10, as demonstrated by both RNA-seq and RT-PCR analyses. During the onset of anthocyanin biosynthesis in apple fruit skin, miR172 transcript abundance was negatively correlated and MdAP2_1a mRNA concentration was positively correlated with fruit skin red-colouration. The positive role of MdAP2_1a in regulating anthocyanin biosynthesis was supported by the enhanced petal anthocyanin accumulation in transgenic tobacco plants overexpressing MdAP2_1a, and by the reduction in anthocyanin accumulation in apple and cherry fruits transfected with an MdAP2_1a virus-induced-gene-silencing construct. We demonstrated that MdAP2_1a could bind directly to the promoter and protein sequences of MdMYB10 in yeast and tobacco, and enhance MdMYB10 promotor activity. In Arabidopsis, over-expression of miR172 reduced anthocyanin concentration and RNA transcript abundance of anthocyanin genes in plantlets cultured on medium containing 7% sucrose. The anthocyanin content and RNA abundance of anthocyanin genes could be partially restored by using a synonymous mutant of MdAP2_1a, which had lost the miR172 target sequences at mRNA level, but not restored by using a WT MdAP2_1a. These results indicate that miR172 inhibits anthocyanin biosynthesis through suppressing the expression of an AP2 transcription factor that positively regulates MdMYB10.

Project description:Purple-grain wheat are caused by anthocyanin accumulation in the seed coat. The anthocyanin biosynthesis and accumulation were affected by light in purple-grain wheat. The spikes of purple-grain wheat Luozhen No.1 were bagged with four-layer Kraft paper bags after pollination. To identify genes involved in the anthocyanin biosynthesis, we sequenced two pericarp cDNA libraries, D20 (20 DAP) of shading treatment, and L20 (20 DAP) of untreated control using an Illumina HiSeqTM 2000.

Project description:n Arabidopsis and other species, anthocyanin accumulation specifically depends on light signaling. The CONSTITUTIVELY PHOTOMORPHOGENIC1/SUPPRESSOR OF PHYA-105 (COP1/SPA) complex is required for the control of anthocyanin biosynthesis in response to light, but the precise mechanism underlying this process is largely unknown. Here we report that Increase in BONSAI Methylation 1 (IBM1), a JmjC domain-containing histone demethylase, participates in the regulation of light-induced anthocyanin biosynthesis in Arabidopsis. Loss-of-function mutations of IBM1 lead to accelerated anthocyanin accumulation in high light. We further identified that IBM1 is directly associated with SPA1/2/3 chromatin in vivo, whereas knockout of IBM1 resulted in an elevated level of H3K9 methylation and DNA non-CG sites within SPA genes, thereby repressing their expression. Transgenic ibm1 plants overexpressing SPA1demonstrated that SPA1 was capable of complementing the mutant phenotype. Our results reveal a novel mechanism that controls the epigenetic regulation of anthocyanin biosynthesis and offer insight into how plant adapt to high light stress. This study could contribute to a better understanding of the linkage between light signaling and anthocyanin biosynthesis in plants

Project description:Anthocyanin induction in plant is considered a general defense response against biotic and abiotic stresses. The infection by Ustilago maydis, the corn smut pathogen, is accompanied with anthocyanin induction in leaf tissue. We revealed that anthocyanin is intentionally induced by the virulence promoting secreted effector protein Tin2. Tin2 protein functions inside plant cells where it interacts with cytoplasmic maize protein kinase ZmTTK1. Tin2 masks an ubiquitin-proteasome degradation motif in ZmTTK1 leading to a more stable active kinase. Active ZmTTK1 controls transcriptional activation of genes in the anthocyanin biosynthesis pathway rerouting phenylalanine away from lignin biosynthesis. Therefore, we performed microarray analysis to understand how maize gene transcription in phenylpropanoid pathway is differentially changed after infection with Ustilago maydis SG200 (wild type) and SG200Dtin2 (anthocyanin-inducing effector mutant).
