Fig. 1: Cold-response patterns of StRAP2.3 during storage periods and sequence analysis of StRAP2.3.

a Expression patterns of StRAP2.3 and StInvInh2 in potato tubers during 20 °C and 4 °C storage periods, assessed via qRT-PCR. Potato CIS-sensitive genotypes: E3 and ED25; potato CIS-resistant genotypes: AC030-06 and AC142-01. b Correlations of fold-changes of StRAP2.3 and StInvInh2 in stored tubers. c Phylogenetic tree of ERF-VIIs from potato, Arabidopsis, and tomato. The tree is based on the alignment of the amino acid sequences using the neighbor-joining method with 1000 bootstraps in Mega X. The expression level of potato ef1α (AB061236) was set as 100 and used for normalization. Each data point represents the mean value of three readings
