Profile of metabolic pathway annotations for the nrFLcDNAs according to LycoCyc. To obtain LycoCyc annotations for the nrFLcDNAs, similarity between nrFLcDNAs and SGN tomato unigenes was assessed using BLASTN. The top hit SGN tomato unigene to each nrFLcDNA was extracted at a threshold E-value of 1e-180 (gray bars). LycoCyc pathway annotations for the top hit unigenes were then regarded as annotations for nrFLcDNAs. Pathway annotations for all SGN tomato unigenes (black bars) was retrieved from documents of LycoCyc ver 220.127.116.11. Asterisks indicate that the difference in the frequency is statistically significant at 5% level.
