ABSTRACT Of the three types of cytoskeleton known in animals—actin, microtubules, and intermediate filaments—only actin and microtubules exist in plants. Both play important roles in cellular shaping, organelle movement, organization of the endomembrane system, and cell signaling.

Making Two out of One: Kinesin Motors Driving Plant Cell Division
ABSTRACT The Kinesin superfamily of microtubule dependent motors is present in all eukaryotes. Not all of the subfamilies are represented in all kingdoms, and the ones that are do not always show conserved functions. Tight control of the cytoskeleton is essential for proper progression and completion of mitosis and cytokinesis, and key functions are ...

LZTS2 Negatively Regulates Centrosomal CEP135 Levels and Microtubule Nucleation
ABSTRACT The microtubule cytoskeleton is a fundamental functional component of the cell. In vertebrate proliferating cells, centrosomes are the primary microtubule organizing center (MTOC), and their dysregulation has been linked to genomic instability and cancer.

ABSTRACT Pollen is a male gametophyte of angiosperms. Following meiosis, the microspore undergoes an asymmetric division called pollen mitosis I (PMI), which produces two cells of different sizes: a large vegetative cell and a small generative cell. Polarized nuclear migration and positioning during PMI are important for successful pollen development ...

Discovery of an Atypical Arp2/3 Complex in Malaria Parasites Sheds New Light on Nuclear Actin
ABSTRACT The Arp2/3 complex is a key actin nucleator essential for cytoskeletal dynamics in eukaryotes. Previously believed absent in apicomplexan parasites, we recently identified an atypical Arp2/3 complex in malaria parasites consisting of five divergent subunits and a putative kinetochore‐associated factor.

ABSTRACT Elastic tethers connect telomeres of separating chromosomes in anaphase of animal cells. Immunofluorescence staining of titin in crane‐fly spermatocytes, using 4 different antibodies, shows that the giant elastic protein titin seems to be a component of mitotic tethers: titin “strands” extend between separating chromosomes, connecting their ...
