Actin microfilaments (F-actin) serve as the track for directional movement of organelles in plant cells. In actively growing cells, F-actin often form robust bundles that trespass cellular dimension. To test how network was employed peroxisome movement, we wished to disturb actin organization by genetically compromising function villin (VLN) proteins primary bundling factor Arabidopsis thaliana do so, isolated T-DNA insertional mutants three VLN genes were most expressed vegetative tissues....
ABSTRACT Plant growth is dependent on oriented cell divisions that employ the microtubular preprophase band (PPB) to position plate. It has been intriguing how this transient cytoskeletal array imprints spatial information be read by cytokinetic phragmoplast at later stages of mitotic division. In Arabidopsis thaliana , we discovered PPB recruited Myosin XI motor MYA1 cortical division site where it joined microtubule-associated proteins and motors form a ring prominent assemblies which...
Abstract Microtubule (MT) motors in the Kinesin-14 subfamily proliferated photosynthetic organisms and they often incorporated sequences bearing novel structural features. To gain insights into functions of diversified from an evolutionary perspective, we performed phylogenetic analyses across different eukaryotic kingdoms. Compared to fungi that have a single class Kinesin-14, early divergent protist Giardia possesses two classes motile green alga Chlamydomonas produces four (Kinesin-14A...
In plant vegetative tissues, cell division employs a mitotic microtubule array called the preprophase band (PPB) that marks cortical site. This transient cytoskeletal imprints spatial information to be read by cytokinetic phragmoplast at later stages of division. Arabidopsis thaliana, we discovered PPB recruited Myosin XI motor MYA1 site where it joined microtubule-associated proteins and motors form ring prominent assemblies which received expanding phragmoplast. regulatory function in...
The acentrosomal spindle apparatus has kinetochore fibers organized and converged towards opposite poles, however mechanisms underlying the organization of these microtubule into an orchestrated bipolar array are largely unknown. Kinesin-14D is one four classes Kinesin-14 motors that conserved from green algae to flowering plants. In Arabidopsisthaliana, three members displayed cell cycle-dependent distinct localization patterns on mitotic spindles microtubules. Notably, Kinesin-14D1 was...
