Fig. 2.

cdkg1–1 mutants are conditionally defective in meiosis. (A) Resin sections of staged (5, 7) anthers from WT and cdkg1–1 mutant plants illustrating normal tetrads in WT stage 7 anthers and aborted tetrads in the mutant (arrowheads). (Scale bar, 25 μm.) (B) Chromatin configuration at different stages (as indicated to the Left) of meiosis in WT and mutant grown at 23 and 12 °C. Arrows indicate unsynapsed regions in a pachytene nucleus and univalents in metaphase I, and arrowheads indicate missegregated meiotic products. (Scale bar, 2 μm.)
