Abstract:
The Arabidopsis genome has two similar dynamin-like proteins, ADL2a and ADL2b (76.7% identity). ADL2a is reported to be localized in chloroplasts [Kang et al. (1998) Plant Mol. Biol. 38: 437], while ADL2b functions in mitochondrial division [Arimura and Tsutsumi (2002) PROC: Natl. Acad. Sci. USA 99: 5727]. Using GFP fusion proteins, we observed both ADL2a and ADL2b in portions of mitochondria but not in chloroplasts. Furthermore, cells transformed with ADL2a and ADL2b with a defective GTPase domain had normal chloroplasts but elongated mitochondria. These results imply that both ADL2b and ADL2a are involved in the division of plant mitochondria.

The timing and cell division patterns of meiosis differ between males and females. In male meiosis, the centrosomes are part of the formation of the meiotic spindle. However, in oocytes, including that of humans, Drosophila,...
