Profile of GO annotations for nrFLcDNAs. To obtain GO annotations for nrFLcDNAs, similarity between the amino acid sequences predicted from nrFLcDNAs and Arabidopsis proteins was assessed using BLASTP. Arabidopsis genes corresponding to the top hit Arabidopsis protein to each nrFLcDNA was chosen at threshold E-values of 1e-50 (gray bars). GO annotations for nrFLcDNAs were then retrieved by subjecting the list of Arabidopsis genes to a TAIR GO annotation search http://www.arabidopsis.org/tools/bulk/go/index.jsp. GO annotations for all Arabidopsis genes (black bars) were retrieved from the TAIR GO annotation search. No statistically significant difference in the frequency was observed in all categories.
