  • a Numbers of EST clones corresponding to CAZyme-encoding genes and expansins (top half) or the number of genes with at least one corresponding EST (bottom half) in the collection of similar-sized cDNA libraries representing different tissues/developmental stages.

  • b Libraries constructed from amplified cDNA, not directly comparable to other libraries but comparable to each other and internally.
