Cellular growth of the etiolated Arabidopsis hypocotyl. University of Antwerp
The Arabidopsis hypocotyl has two growth phases. During the first phase, all cells grow slowly and synchronous and they are 'prepared' to start the second phase. During the fast asynchronous growth, cells elongate dramatically. Based on micro-array results specific differentially expressed genes that allow cells to start and proceed through the second growth phase are studied.
