Gene expression patterns based on EST counts. (A) Venn diagram of unigenes detected in the "Early" (15–25 DAF) and "Late" (30–40 DAF) guar cDNA libraries. (B) Distribution of unigenes from the "secure" assignment category in classes of putative function. The classes of putative gene functions are presented in alphabetical order based on the description of the best match from BLASTX similarity searches to the non-redundant GenBank protein databases. (C) Comparison of EST numbers in the "early" and "late" development stage cDNA libraries, distributed into classes of putative function.
