Small RNA and degradome deep sequencing of Chinese wild grapevine and cultivated grapevine

Chinese wild grapevine (Vitis amurensis) has remarkable cold stress tolerance, exceeding that of the common cultivated grapevine (Vitis vinifera L.).Here, we surveyed the expression dynamics of microRNAs (miRNAs) across Chinese wild grapevine (cv. Beibinghong) and cultivated grapevine (cv. Cabernet Sauvignon) under cold stress using high-throughput sequencing. Degradome deep sequencing were performed to detect and analyze cold-related miRNAs and their target genes in Chinese wild grapevine and Cabernet Sauvignon, a cold-sensitive grapevine cultivar (cv).
