A xyloglucan endotransglucosylase/hydrolase gene, IbXTH16, increases cold tolerance in transgenic sweetpotato
The <i>IbXTH16</i> gene was cloned from the cold-tolerant variety LHS21. Its 879 bp coding sequence encoded a 292 aa protein with a molecular weight of 32.983 kDa and a pI of 8.47. The 2039 bp genomic sequence of <i>IbXTH16</i> contained two exons and one intron. The IbXTH16 protein was localized in the cell membrane. <i>IbXTH16</i> was strongly induced by 4°C and brassinosteroid. <i>IbXTH16</i> positively regulates cold tolerance of sweetpotato by activating the BR and proline pathways.
