Figure 1From: Dynamic changes in transcripts during regeneration of the secondary vascular system in Populus tomentosa Carr. revealed by cDNA microarraysNumber of genes with differences in transcript levels between adjacent stages of SVS regeneration. The numbers of genes showing differences in transcript levels between adjacent stages (x-axis) during SVS regeneration as determined by cDNA microarray analysis are shown; 363 genes were shown to have dynamic transcript levels during SVS regeneration. Larger numbers of genes were up- or downregulated on days 10, 14, and 22 AG than at other points, indicating that the transcriptional profiles changed dramatically at these key switches between regeneration stages.Back to article page
