植物次生代謝基因簇研究進(jìn)展
[Abstract]:Similar to the operons of prokaryotes, clusters of non-homologous genes are also found in eukaryotes (such as yeast, fungi, insects, etc.). These genes form a cluster of genes that can be involved in multiple secondary metabolic pathways. In recent years, more and more gene clusters involved in the synthesis of secondary metabolites have been found in plants, and they have become a hotspot in plant biology. In this paper, the identified secondary metabolic gene clusters in plants were summarized and analyzed. These gene clusters exist in maize (Zea mays L.), rice (Oryza sativa L.), Arabidopsis thaliana (Arabidopsis thaliana (L.) Heynh.), tomato (Solanum lycopersicum L.) They are involved in the synthesis of secondary metabolites, such as benzoVA azosinones, terpenoids and alkaloids, respectively. In this paper, the molecular mechanism of gene cluster formation and its regulatory mechanism are discussed by analyzing the composition and structural characteristics of these gene clusters, and summarizing their characteristics. The research direction and application prospect of plant secondary metabolic gene cluster in synthetic biology and metabolic engineering are prospected.
