Fig. 1: FANCM promotes formation of obligate chiasma.

a TtFANCM coding region for the A and B homoelogs with conserved domains shown (DEAD-like helicases superfamily (DEXDc) and helicase superfamily c-terminal (HELICc)), and TILLING mutations (red) indicated. b TaFANCM coding region for the A, B and D homoelogs with conserved domains shown (DEXDc and HELICc), and TILLING mutations (red) and VIGS target sites (black) indicated. c Box plot of chiasmata frequency per male meiocyte. Box extends from the 25th to 75th percentile, the centre line is the median value and the whiskers denote min and max values. The number of meiocytes sampled for each line is shown in brackets. n.s. = p > 0.05. *** = p < 0.001 (Pairwise Wilcoxon Rank Sum Test with Bonferroni correction). d Proportion of rings, rods and univalents per male meiocyte. The number of meiocytes sampled for each line is shown in brackets. Source data are provided as a Source Data file.
