  1. Orthologues of the potato PTB1/6 proteins in storage root crops. Among the PTB orthologues in each storage root crop, proteins with the best coverage and identity (highlighted in bold) were used in the multiple sequence alignment (Fig. 1) and phylogenetic analysis (Fig. 2). Sequence of StPTB1 was used for the query in this analysis. The same results were obtained using StPTB6 as a query because StPTB1 and StPTB6 amino-acid sequences have a close similarity. PTB orthologues with potential four RRMs are considered as PTB1/6-types, whereas those with three RRMs as PTB7 types
