Deposition of lignin in secondary cell walls has been considered to be essential for the evolution of land plants. In the present study, we examined the effects of hypergravity conditions on lignin deposition in secondary cell walls of Arabidopsis inflorescence stems. Plants were grown for 3 days after exposure to basipetal hypergravity at 300 x g for 24 h. A secondary cell wall fraction was prepared by enzyme digestion of inflorescence stem segments to remove primary cell wall components. The content of lignin in a secondary cell wall fraction was significantly increased by hypergravity stimulus. Microarray analysis (22K) was used to identify genes that are modulated in expression in response to hypergravity conditions. The data showed that many genes putatively involved in lignin biosynthesis were expressed more than 2-fold by hypergravity treatment. Our data confirm that hypergravity-induced increase in the content of the constituents of secondary cell walls is due to the increased expression of genes responsible for the formation of secondary cell walls under hypergravity conditions., 共催: 日本学術会議, Meeting sponsors: The Science Council of Japan, The Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (ISAS)(JAXA), 資料番号: AA0064113100},
