Special Issue Information

Dear Colleagues,

Plants produce a terrific panoply of metabolites involved in many biological mechanisms, which can be exploited for the wellbeing of humans and environment. This array of compounds includes valuable molecules with a broad spectrum of application. As green factories, plants may provide bioactive molecules, proteins, carbohydrates and biopolymers for a sustainable, large-scale production of commodities such as pharmaceuticals, antioxidants, food, feed, chemicals, materials and biofuels for multiple industrial processes. Insights on biosynthesis, catabolism and regulation of these bioactive molecules can be pursued through advanced molecular tools coupled with metabolomics, which in turn allow an accurate identification of the main biosynthetic genes and molecular mechanisms involved in the accumulation of these compounds. Moreover, synergy between disciplines also apparently distant such as plant physiology, pharmacology, ‘omic sciences, bioinformatics and nanotechnology, paves the path to the emergence of novel applications of plants as metabolic factories of bioactive compounds for wide-ranging purposes.

The Forthcoming Special Issue intends to deepen knowledge on plant-based compounds biosynthesis and its orchestration and on innovative approaches of plant biotechnology highly relevant for the development of sustainable improvements in food quality, nutrition, public health and bioenergy.

The generation of chrysanthemum (Chrysanthemum × morifolium) flower color is mainly attributed to the accumulation of anthocyanins. In the anthocyanin biosynthetic pathway in chrysanthemum, although all of the structural genes have been cloned, the regulatory function of R2R3-MYB transcription factor (TF) genes, which play a crucial role in determining anthocyanin accumulation in many ornamental crops, still remains unclear. In our previous study, four light-induced R2R3-MYB TF genes in chrysanthemum were identified using transcriptomic sequencing. In the present study, we further investigated the regulatory functions of these genes via phylogenetic and alignment analyses of amino acid sequences, which were subsequently verified by phenotypic, pigmental, and structural gene expression analyses in transgenic tobacco lines. As revealed by phylogenetic and alignment analyses, CmMYB4 and CmMYB5 were phenylpropanoid and flavonoid repressor R2R3-MYB genes, respectively, while CmMYB6 was an activator of anthocyanin biosynthesis, and CmMYB7 was involved in regulating flavonol biosynthesis. Compared with wild-type plants, the relative anthocyanin contents in the 35S:CmMYB4 and 35S:CmMYB5 tobacco lines significantly decreased (p < 0.05), while for 35S:CmMYB6 and 35S:CmMYB7, the opposite result was obtained. Both in the 35S:CmMYB4 and 35S:CmMYB5 lines, the relative expression of several anthocyanin biosynthetic genes in tobacco was significantly downregulated (p < 0.05); on the contrary, several genes were upregulated in the 35S:CmMYB6 and 35S:CmMYB7 lines. These results indicate that CmMYB4 and CmMYB5 negatively regulate anthocyanin biosynthesis in chrysanthemum, while CmMYB6 and CmMYB7 play a positive role, which will aid in understanding the complex mechanism regulating floral pigmentation in chrysanthemum and the functional divergence of the R2R3-MYB gene family in higher plants.
