Chlamydomonas surrenders

Article Abstract:

The molecular biology and genetics of the unicellular alga Chlamydomonas were the subjects of an international conference held in Pacific Grove, CA, May 26-31, 1992. Participants heard reports on the progress toward deriving a whole-organism model system from Chlamydomonas comparable to the systems that yeast and the fly Drosophila have yielded. Topics addressed included the use of transformation as a type of mutagenesis capable of disrupting and targeting specific genes and the effort to find rare cases of homologous integration.

Inner-arm dynein c of Chlamydomonas flagella is a single-headed processive motor

Article Abstract:

Axonemal dyneins occur in many isoforms producing movement of eukaryotic cilia and flagella. Inner-arm dyneins may mainly produce bending moments in flagella. Studies of microtubules over a surface coated with subspecies-c at low densities, show that a single molecule is enough to move a microtubule more than 1 mu m at 0.7 mu m. Beads having a single subspecies-c motor were shown to move processively along the microtubules in 8-nm steps, falling backwards under high loads.

miRNAs control gene expression in the single-cell alga Chlamydomonas reinhardtii

Article Abstract:

The study of miRNAs that guide post-transcriptional regulation, found only in multicellular organisms revealed its presences in Chlamydomonas reinhardtii a single cell alga.
