Research Abstract |
Focusing Arabidopsis kamchatica that is distributed over 30 - 3000 m altitude; we (1) clarified adaptive evolution had already occurred in the field transplant experiment, (2) clarified altitudinal cline in flowering and germination timing in the laboratory growth experiment, (3) quantified phenotypic plasticity in flowering timing in the laboratory growth experiment, (4) indicated the change in flowering timing depending on environment that maternal individuals experienced, (5) identified three "altitude adaptation genes" whose allele frequencies were drastically differentiated along altitude, and (6) sampled DNA and initiated epigenetics analytical system utilizing bisulphate treatment and next-generation sequencing, for investigating epigenetic variation across different environmente.
