It was demonstrated that gene expression analysis was useful and less time-consume to evaluate plant response of chrysanthemum and leafy lettuce to environmental factors compared with the conventional and long-term evaluation method that plant growth and response are measured a few times a week. A possible increase of stem growth rate of lettuce was indicated by control the gene expression level of Ls2ox2, and a new knowledge about the photo-environment control technology that used onset of gibberellin metabolism gene analysis of a certain lettuce was obtained.It is thought that measurement procedure of the plant growth applying gene expression analysis is feasible to improvement of the plant production efficiency and production cost reduction of the plant factory system.
