All organisms have much information to make and maintain their body. The transgenerationally inherited information is called genetic information. Based on the information, biologically functional proteins are produced with gene expressions. Genetic information is not always expressed; rather the information is switched on and off by suitable timing through life span. A mechanism of gene regulation contains an important issue when understanding how our body is made and how it works. Genetic information is transcribed to a messenger RNA and translated to an amino acid. Recent studies showed that gene expression is regulated by epigenetic modifications that include DNA methylation and histone modifications and also controlled by RNA molecules. We study the mechanism of gene regulations by using genetics and molecular approaches in plants.
\nAlso, is has been appeared that gene expressions and transposon activations are affected by environmental stress. In nature, high copy numbers of transposons are conserved in many species. This may imply that transposons have been activated by environmental stress and changed the genome structure of a host genome. A transposition may cause mutation of a host gene. Sometimes the mutation promotes genome evolution and gene diversity that can adapt a new environment. We study the effect of environmental stress in plants. We focus on the regulation mechanism of stress-activated transposons and analyze the relationships between the transposons and the host genome.<\/p>\n
