Using transcriptome data to deve lop SSR marker is an economical and effective method of DNA molecular marker for the moment. In order to develop more SSR markers suitable for sweetpotato, we searched the FASTA sequences that were equal or longer than 1 000 bp from 105 959 Unigenes obtained based on sequencing the transcription de novo of somatic hybrid KT1 and 24 samples treated with 4 drought stresses in two parents of sweetpotato previously, and 12 105 SSR loci were found. Two hundred pairs of SSR primer...
