Project description:Stock (Matthiola incana (L.) R. Br.) is a famous annual ornamental plant with important ornamental and economic value. The lack of DNA molecular markers has limited genetic analysis, genome evolution, and marker-assisted selective breeding studies of M. incana. Therefore, more DNA markers are needed to support the further elucidation of the biology and genetics of M. incana. In this study, a high-quality genome of M. incana was initially assembled and a set of effective SSR primers was developed at the whole-genome level using genome data. A total of 45,612 loci of SSRs were identified; the di-nucleotide motifs were the most abundant (77.35%). In total, 43,540 primer pairs were designed, of which 300 were randomly selected for PCR validation, and as the success rate for amplification. In addition, 22 polymorphic SSR markers were used to analyze the genetic diversity of 40 stock varieties. Clustering analysis showed that all varieties could be divided into two clusters with a genetic distance of 0.68, which were highly consistent with their flower shape (potted or cut type). Moreover, we have verified that these SSR markers are effective and transferable within the Brassicaceae family. In this study, potential SSR molecular markers were successfully developed for 40 M. incana varieties using whole genome analysis, providing an important genetic tool for theoretical and applied research on M. incana.

Project description:Matthiola incana is an important floricultural plant that blooms from winter to spring, and had been desired to be established a transformation system. This study successfully obtained stable transgenic plants from M. incana. We used Agrobacterium tumefaciens harboring a binary vector containing the β-glucuronidase gene (GUS) under the control of cauliflower mosaic virus 35S promoter to evaluate the transformation frequency of M. incana. We observed that cocultivation with the A. tumefaciens strain GV3101 for 5 days effectively enhanced the infection frequency, assessed through a transient GUS expression area in the seedling. Furthermore, the addition of 100 µM acetosyringone was necessary for Agrobacterium infection. However, we could not obtain transgenic plants on a shoot formation medium supplemented with 1 mg l-1 6-benzyladenine (BA). For callus formation from the leaf sections, a medium supplemented with 1-50 µM fipexide (FPX), a novel callus induction chemical, was employed. Then, the callus formation was observed after 2 weeks, and an earlier response was detected than that in the BA medium (4-6 weeks). Results also showed that cultivation in a selection medium supplemented with 12.5 µM FPX obtained hygromycin-resistant calli. Thus, this protocol achieved a 0.7% transformation frequency. Similarly, progenies from one transgenic line were observed on the basis of GUS stains on their leaves, revealing that the transgenes were also inherited stably. Hence, FPX is considered a breakthrough for establishing the transformation protocol of M. incana, and its use is proposed in recalcitrant plants.

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.
