Arabidopsis CLE41 regulates vascular organisation, cell division and xylem differentiation. 35S::CLE41 lines are characterised by an increase in the number of undifferentiated cells in vascular bundles and by radial patterning defects. To identify further genetic components involved in controlling vascular development, we compared the transcriptomes of one 35S::CLE41 line with that of wild type counterparts using microarray analysis. Inflorescence stem tissue was compared in 5 weeks old plants 1 cm above the rosette leaves where vascular bundles of 35S::CLE41 plants contained an average of 100.7 ± 9.1 undifferentiated cells compared to 59.5 ± 5.5 in wild type counterparts. Genes with a putative role in vascular development demonstrate changes in gene expression between the two genotypes tested. Overall design: 6 samples; 3x wild type replicates, 3x 35S::CLE41 replicates Less...
