Survey of genome sequences in a wild sweet potato, Ipomoea trifida (H. B. K.) G. Don.

ABSTRACT: Ipomoea trifida (H. B. K.) G. Don. is the most likely diploid ancestor of the hexaploid sweet potato, I. batatas (L.) Lam. To assist in analysis of the sweet potato genome, de novo whole-genome sequencing was performed with two lines of I. trifida, namely the selfed line Mx23Hm and the highly heterozygous line 0431-1, using the Illumina HiSeq platform. We classified the sequences thus obtained as either 'core candidates' (common to the two lines) or 'line specific'. The total lengths of the assembled sequences of Mx23Hm (ITR_r1.0) was 513 Mb, while that of 0431-1 (ITRk_r1.0) was 712 Mb. Of the assembled sequences, 240 Mb (Mx23Hm) and 353 Mb (0431-1) were classified into core candidate sequences. A total of 62,407 (62.4 Mb) and 109,449 (87.2 Mb) putative genes were identified, respectively,
