From: Transcriptomic analysis of Arabidopsis developing stems: a close-up on cell wall genes
Genes encoding secreted proteins having modulated level of expression during stem development. Three transitions were analyzed: from young to intermediate stage of development, from intermediate to mature, and from young to mature. Numbers of genes that are up-regulated and down-regulated during these transitions are represented by white and grey bars respectively. Data are shown in Additional file 3.
