A new paper on cytokinesis in Chlamydomonas has been published in PNAS.
https://doi.org/10.1073/pnas.1920337117
In this paper, we demonstrated that F-actin is enriched in the cleavege-furrow region of dividing Chlamydomonas cells by using Lifeact marker. Interestingly, however, there is no myosin co-localizing with F-actin in the furrow, suggesting that no “actomyosin” structure is directly involved in furrowing. Moreover, complete removal of F-actin by a combination of an actin toxin latrunculin B and a mutation in NAP1 (which encodes a latrunculin-resistant, unconventional actin – see our previous publications 1,2) did not completely block furrow ingression. Because microtubules are still associated with the furrows formed in the absence of F-actin, we believe that this cytoskeleton plays a major role in cytokinesis, which may have been inherited from very early ancestors of eukaryotes, or even earlier ancestors shared with archaea and bacteria.

We will investigate the fundamental core mechanisms of cytokinesis and their evolution from the common ancestors, using Chlamydomonas in our lab, and with collaborators who use other systems. Join us for this exciting expedition!!
