Special Issue Information

Dear Colleagues,

Metabolism, both inorganic and organic, is the foundation of plant growth and development. The various metabolic processes of plants form a three-dimensional network, which includes regulatory modes existing in metabolic pathways, such as the formation of metabolic pathways, as well as multi-gene and multi-level regulatory networks at the transcriptome and even epigenetic levels. In addition, in multicellular individuals of higher plants, the metabolism and regulatory networks of different cell types, tissues, and organs at different developmental stages form the overall network, which is regulated by and responds to the external environment. The construction of plant metabolic regulatory networks involves multiple factors, including gene expression, metabolite distribution, and external environmental factors. In the metabolic regulatory network, signal transduction is very important. Plants regulate metabolic processes through exogenous and endogenous signals to meet the needs of environmental adaptation and growth and development. By utilizing modern molecular biology and various omics technologies, analyzing and understanding the plant metabolic network and molecular mechanism will help us gain a deeper understanding of the life processes of plants and their adaptability to the environment. It will also facilitate the targeted modification of plant metabolic pathways through genetic engineering methods to obtain the desired target compounds.

This Special Issue includes, but is not limited to, the following topics:

  1. Exploring new genetic resources;
  2. Metabolic pathway analysis;
  3. Biosynthesis;
  4. Transcriptional regulation.

Endogenous inhibitors can inhibit seed germination, and GA3 can promote seed germination. Whether GA3 can affect the changes in endogenous inhibitors has not been clarified. In order to study the effect of GA3 on the endogenous inhibitors in sainfoin (Onobrychis viciifolia) seeds, the systematic separation method and gas chromatography–mass pectrometry (GC-MS) method were used to determine the endogenous inhibitors using cabbage (Brassica rapa var. glabra Regel) as a bioassay model to validate the inhibitory activity in sainfoin seeds, and then the optimal concentration of GA3 was determined to promote seed germination. The results showed that endogenous inhibitors existed in the pod coat, seed coat, and seed embryo of sainfoin seeds, with the methanol and ethyl acetate phases showing the highest degree of inhibition. The organic compounds were mainly organic acids, phenols, lipids, and alkanes. The levels of changes in germination indicators, storage substances, and antioxidant enzymes determined that 600 mg/L GA3 was the optimum concentration to promote germination of sainfoin seed. It was also found that 600 mg/L GA3 reduced the relative content of endogenous inhibitors and changed the content of endogenous hormones. In summary, the presence of endogenous inhibitors may be one of the reasons for the low germination rate of sainfoin seeds, with 3-methoxycatechol and 4-nitrosodiphenylamine playing a major role. GA3 can reduce the relative content and types of endogenous inhibitors to promote the germination of sainfoin seeds. Our experimental results provide the basis for subsequent exploration of the mechanism of specific endogenous inhibitors and the identification of deeper molecular mechanisms. Full article
