Microtubule-associated proteins (MAPs) play important roles in the regulation of microtubule function in cells. We describe Arabidopsis thaliana MAP18, which binds to microtubules and inhibits tubulin polymerization in vitro and colocalizes along cortical microtubules as patches of dot-like structures. MAP18 is expressed mostly in the expanding cells. Cells(More)
Many antimicrobial peptides from amphibian skin have been purified and structurally characterized and may be developed as therapeutic agents. Here we describe the antibacterial properties and membrane interaction of chensinin-1, a cationic arginine/histidine-rich antimicrobial peptide, from the skin secretions of Rana chensinensis. The amino acid(More)
