| Research Abstract |
Since little is known about molecular mechanisms of asymmetric cell division in plants, we undertook to identify genes that are involved in the processes. The moss, Physcomitrella patens provides a good system for the study of asymmetric cell division. We identified more than 60 genes that impaired asymmetric cell division when overexpressed. We explored dynamics of the candidate's proteins during asymmetric cell division by introducing a yellow fluorescent protein as a tag into the c-terminus. We found proteins with unknown function, plant-specific transcription factors, chromatin remodeling factors, small G proteins related to asymmetric cell division. Moreover, putative cell wall proteins are responsible for a suppression of the asymmetric cell division.
