Abstract
Studies have shown that some plant-specific NAC (NAM, ATAF1/2, CUC2) transcription factors may increase plants resistance to stress. We screened the genes differentially expressed in transgenic SlNAC1 Arabidopsis compared to the wild type by cDNA microarry, to provide scientific basis for studying the genes related to abiotic stress responses in transgenic Arabidopsis. There were 3 046 genes differentially expressed more than twice in the total 43 604 genes of transgenic SlNAC1 Arabidopsis. Gene ontology analysis was used on genes differentially expressed more than five-fold. Genes relevant to cellular components occupied 33.05%, genes correlated with molecular function accounted for 33.95% and genes pertinent to biological process constituted a 33.00% portion. The genes differentially expressed more than twice were processed through kyoto encyclopedia of genes and genomes pathways enrichment (KEGG) analysis. The total 2 431 genes were involved in 88 different signaling pathways. The screened genes related to abiotic stress responses provide direction and theoretical support for the following research on the downstream genes regulated by NAC and construction of the regulatory networks.
