Figure 4From: De novo assembly and characterization of root transcriptome using Illumina paired-end sequencing and development of cSSR markers in sweetpotato (Ipomoea batatas)Comparison of unigene length between hit and no-hit unigenes. Longer contigs were more likely to have BLAST matches in protein databases. In this study, 79% of unigenes over 500 bp in length had BLAST matches, whereas only 30% of unigenes shorter than 300 bp did.Back to article page
