Figure 7. Synaptic configuration of the rye chromosome pair in cells at mid zygotene (MZ), late zygotene (LZ) and pachytene (P) in different lines.

Figure 7

A, D, G, J) DAPI image of each nucleus. B, E, H, K) Arrangement of telomeres labeled with probe pAt74 (green) and of the rye bivalent hybridized with probes, pUCM600, pAWRC.1, pSc74 (red) present in each nucleus. C, F, I, L) Schematic representation of the two rye homologues that synapse in each bivalent. B, C) 1RL and 1RLinv show antiparallel arrangement and synapsis at both ends. E, F) Synapsis of the 1Rinv-1Rinv pair involves 1RS and the proximal region of 1RLinv including the proximal chromomere. H, I) Chromosomes 1R and 1Rinv show complete homologous synapsis. K, L) Chromosomes 1R and 1Rinv underwent homologous synapsis of the short arm and non-homologous synapsis of the long arm. Bar represents 10 µm.
