Meiotic configurations in the oospore of Phytophthora capsici

, : Meiotic configurations in the oospore of Phytophthora capsici. Canadian Journal of Botany 52(10): 2141-2143

Photomicrographs of chromosomal configurations in nuclei of squashed whole mounts of mature oospores (cultures 32 days old) of P. capsici stained with iron haematoxylin were interpreted to indicate that meiosis occurred in the oospore. Chromosomes in dividing oospore nuclei were observed in synapsis, diakinesis, and metaphase I and II. Comparison of polar metaphase I and II plates revealed a reduction in chromosome size and number, and nuclear size.
