Project description:Rosa chinensis ‘Pallida’ (Rosa L.) is one of the most important ancient rose cultivars originating from China. It contributed the ‘tea scent’ trait to modern roses. However, little information is available on the gene regulatory networks involved in scent biosynthesis and metabolism in Rosa. In this study, the transcriptome of R. chinensis ‘Pallida’ petals at different developmental stages, from flower buds to senescent flowers, was investigated using Illumina sequencing technology. De novo assembly generated 89,614 clusters with an average length of 428 bp. Based on sequence similarity search with known proteins, 62.9% of total clusters were annotated. Out of these annotated transcripts, 25,705 and 37,159 sequences were assigned to gene ontology and clusters of orthologous groups, respectively. The dataset provides information on transcripts putatively associated with known scent metabolic pathways. Digital gene expression (DGE) was obtained using RNA samples from flower bud, open flower and senescent flower stages. Comparative DGE and quantitative real time PCR permitted the identification of five transcripts encoding proteins putatively associated with scent biosynthesis in roses. The study provides a foundation for scent-related genes discovery in roses.

Project description:Petal is not only the target of selection by horticulturalists to enhance the ornamental value of plants but also emerged as a unique model system for plant organogenesis studies. It is known that three major groups of pigments, betalains, carotenoids and anthocyanins, are responsible for the attractive natural display of flower colors. While carotenoids and betalains generally yield yellow or red colors, anthocyanins confer a diverse range of color from orange to red to violet and blue. In this study, we collected 11 species (Erysimum cheiri, Malcolmia maritime, Brassica oleracea, Raphanus sativus, Orychophragmus violaceus, Eruca sativa, Orychophragmus violaceus, Iberis amara, Aubrieta x cultorum, Lobularia maritime, Matthiola incana) belong to different tribe in Brassicaceae family with varied flower color and performed petal transcriptome analysis. de novo transcriptome assembly showed that average length of the contigs varied from 631bp in O. violaceus to 1212bp in Matthiola incana which indicated that the complexity of the genomes are different much. Protein homology between these species and those sequenced species in Brassicaceae family are consistent with the known phylogenetic relationships. However, O. violaceus has closer relationships with Sisymbrium irio than expected Brassica species. Clustering analysis of genes in anthocyanin and carotenoids synthesis pathway indicated that while silence or low expression of CCD4 (Carotenoid Cleavage Dioxygenase 4) leading to the yellow color formation in different species, purple or red color variation might result from different genes expression variation. These results not only provide transcriptome data for petal development study but also provide useful information for Brassica flower improvement for ornamental purpose.

Project description:Marigold (Tagetes erecta L.) is an important ornamental plant with a wide variety of colors. Despite its economic value, there are few biochemical and molecular basic studies of flower color in marigold. To study the mechanism behind its color formation, metabolomics analysis and de novo cDNA sequencing was performed on marigold inbred line ‘V-01’ and its petal color mutant ‘V-01M’, in four flower developmental stages.

Project description:affy_cinetique_lyon_rose. The objective is to identify genes involved in petal development and senescence. R. chinensis cv Old Blush (OB) was used for the following reasons: it is a diploid Chinese rose that participated in the generation of modern roses (recurrent flowering, scent, etc.). The objective here is to identify genes whose expression is associated with different flower development stages, from floral meristem to senescing flower. These genes are putative candidates involved in floral initiation, development and senescence. All samples were collected at the same time early in the afternoon. Meristems and early flower development stages were dissected under a microscope. Total RNA was extracted from harvested tissues using the Plant RNA kit (Macherey Nagel), and then used to hybridize Rosa-Affymetrix microarrays. Keywords: time course
