Figure 7. Class I COs tend to cluster in axr1.

(A) Examples of adjacent HEI10 or MLH1 foci in wild-type (Wt, Col-0) and in axr1 (N877898 allele) acetic acid spread meiotic chromosomes. (B) Proportion of pachytene and diplotene cells where adjacent foci were observed on the same chromosome axis pair (Wt, wild type; axr1, N877898 allele) (0, no evidence of adjacent foci; 2, two adjacent foci, etc.). Some of these situations are indicated by arrows in panel A. Bar  =  5 µM.
