| Research Abstract |
This work studied plant vitalization effect of nitrogen dioxide(PVEON) in Arabidopsis thaliana. PVEON more than doubled leaf size, which appeared to be attributable to cell expansion, but not to cell division. Reverse genetic study of genes identified by the transcriptome analysis revealed that a novel gene Vita1is involved in the PVEON. Six genes controlling cell expansion differed significantly in temporal gene expression changes between presence and absence of nitrogen dioxide, and their coexpressed genes were analyzed using a gene database ATTED II.
