The application discloses tobacco
isopropyl malate dehydrase NtIPDS, a coding
gene, an RNAi interference carrier and application. The application successfully clones a coding
gene of
isopropyl malate dehydrase in tobacco, and the
nucleotide sequence is as follows: (1) the
nucleotide sequence shown in SEQ ID NO. 1; (2) the
nucleotide sequence shown in SEQ ID NO. 1 is substituted and / or deleted and / or added with one or more nucleotides and the nucleotide sequence of the same
functional protein. Based on the existing tobacco
genetic engineering progress and related
plant phenotype observation and identification, the NtIPDS
gene is deeply researched, and it is found that the NtIPDS gene is related to tobacco
chloroplast development and acyl
sugar metabolism. After the gene is silenced, the
chlorosis plant growth is slow, the
chloroplast development is found to be abnormal
through transmission electron microscope observation, and meanwhile, it is found that the acyl
sugar content of the silenced
plant is significantly increased through metabolic detection analysis.
