Resumo

3-oxy-3-methylglutaryl-CoA reductase (HMG1) catalyzes the formation of mevalonic acid, the key intermediate of the cytosolic isoprenoid synthesis pathway. The parameters of stem and leaf growth were studied in the transgenic tobacco plants that express the HMG1 gene in both sense and antisense directions with respect to the constitutive promoter. The transgenic plant height did not significantly differ from that of the control plants, though the plants carrying the sense copy of the HMG1 gene were considerably taller than plants that carried the antisense gene copy. Plants carrying an extra copy of the HMG1 gene were also characterized by increased leaf area. The number of mesophyll cells calculated per square unit of transgenic plants leaves was smaller than in the control plant leaves, though their volume was not considerably changed in any of the variants, suggesting changes in the cell folding density in leaves. Keywords: transgenic tobacco plants, HMG1 gene, sprout height, leaf area, mesophyll
