AbstractGravity resistance is a response that enables plants to develop against the gravitational force. Hypergravity conditions produced by centrifugation have been used to analyze the mechanisms of gravity resistance responses. Under hypergravity conditions, plants increase the cell wall rigidity for resisting the gravitational force. However, the molecular mechanism inducing gravity resistance responses is not known. To identify genes involved in gravity resistance responses, changes in gene expression by hypergravity stimuli were analyzed by the differential display method and microarray analysis. Here possible roles of genes up-regulated under hypergravity conditions in gravity resistance responses is discussed.
