Genome-wide transcriptome analysis of gametophyte development in Physcomitrella patens.

ABSTRACT:

Background

Regulation of gene expression plays a pivotal role in controlling the development of multicellular plants. To explore the molecular mechanism of plant developmental-stage transition and cell-fate determination, a genome-wide analysis was undertaken of sequential developmental time-points and individual tissue types in the model moss Physcomitrella patens because of the short life cycle and relative structural simplicity of this plant.

Results

Gene expression was analyzed by digital gene expression tag profiling of samples taken from P. patens protonema at 3, 14 and 24 days, and from leafy shoot tissues at 30 days, after protoplast isolation, and from 14-day-old caulonemal and chloronemal tissues. In total, 4333 genes were identified as differentially displayed. Am
