A new ancestral karyotype (AK) system for translational research in Brassicaceae. a Synteny between Camelineae (A. thaliana as extant representative) and Calepineae (B. rapa as extant representative) based on 24 ABC blocks (referred to as blocks A–X; adapted from Schranz et al. [6]) and 16 AK blocks (AK1–16 from the current analysis). The order, orientation and color-coding of the ABC and AK blocks are based on their position in ABK as illustrated in Fig. 1. b Microsynteny at the FLC locus between A. thaliana, C. rubella, A. lyrata, T. parvula and B. rapa based on the ancestral block AK12
