Progression through male meiosis in wild-type plants and homozygous x-ray induced 1-1 mutants. The pollen mother cells are stained with DAPI.

(a–f) Wild-type (WT) meiosis is shown in the stages of early leptotene/leptotene (a, b), pachytene (c), metaphase I (d), metaphase II (e) and a tetrad of meiotic products (f) after the completion of meiosis.

(g–l) Homozygous xri1-1 pollen mother cells at early leptotene/leptotene (g, h), later asynaptic prophase (i), anaphase I (j), anaphase II (k) and polyad (l). Cells in (j), (k) and (l) show extensive chromosome fragmentation. Scale bar = 10 μm.
