| Abstract/Contents: | "Nitrogen is applied frequently due to the lack of nitrogen often happening during the process of crop growth. CO2 is substrate for plant photosynthesis. Our previous study found that carbon and nitrogen interactions mainly affected cell division and cell elongation of leaf that caused leaf elongation. Therefore, we speculated that the above changes were related with cytokinins and auxin. However, it is still unclear about the regulatory mechanisms of carbon and nitrogen interactions affecting cytokinins and auxin in regulating leaf growth. The project will analyze various growth and physiological traits as well as endogenous hormone content related to carbon and nitrogen metabolism to understand the physiological mechanism of carbon and nitrogen interactions controlling leaf growth. Further, the project will spray promotor and inhibitor of cytokinins and auxin in leaves of tall fescue and generate transgenic plants (FaIPT, FaCKX, FaYUCCA, RNAi-FaYUCCA) controlling cytokinins and auxin synthesis and degradation in tall fescue in order to analyze phenotype as well as cytokinins and auxin level to determine that carbon and nitrogen interactions controlling leaf growth was associated with cytokinins and auxin. Then, transcriptomics and metabolomics will be performed on transgenic lines to identify key metabolites and genes related with cytokinins and auxin in response to carbon and nitrogen interactions. Understanding mechanisms about carbon and nitrogen interactions affecting cytokinins and auxin in regulating leaf growth in tall fescue have important theoretical significance for efficient management and breed improvement of turfgrasses under the scenario of climate change with increasing elevated atmospheric CO2 concentration and decreasing nitrogen utilization in soil." |
