Potato(Solanum tuberosum L.)is the most important tuber crop globally.The increasing fre-quency of extreme global climates and the expansion of potato cultivation areas make potatoes vulner-able to extreme weather disasters.Frost damage is a common climate disaster in potato production as cultivated potatoes are not frost-resistant.Once severe frost damage occurs,it significantly affects po-tato production.Through transcriptome sequencing of two different potato materials with cold sensi-tivity and cold tolerance,and found that there were 7 522 differential genes among 22 717 detected genes.KEGG analysis revealed that cold treatment showed specific enrichment of lipid metabolism at the transcriptional level.After further analysis five candidate genes of the lipid metabolism pathway,PKT3,SMT2,SMT3,PECT1 and SMT3,were up-regulated after low-temperature treatment and highly correlated with cold resistance.
