The transcriptional regulation of the cell cycle in plants has features in common with other higher eukaryotes, as well as potential plant-specific pathways. In the Early Edition of the
They applied a cDNA-amplified fragment length polymorphism (AFLP) technology to overcome the limitations imposed by the lack of extensive genomic and microarray resources for tobacco. Analysis of about 10,000 transcript tags revealed that 10% of transcripts were periodically expressed. Hierarchical clustering identified clusters associated with the phases of the cell cycle. About one third of the tags are homologous to genes of known function. Breyne et al identified genes encoding cyclins, kinases and phosphatases previously associated with cell-cycle progression, as...
