Cellulose is a major component of plant cell walls and is necessary for plant morphogenesis and biomass. COBL (COBRA-Like) proteins have been shown to be key regulators in the orientation of cell expansion and cellulose crystallinity status. To clarify the role of a cotton COBL gene, GhCOBL9A, we
The orientation of cell expansion is a process at the heart of plant morphogenesis. Cellulose microfibrils are the primary anisotropic material in the cell wall and thus are likely to be the main determinant of the orientation of cell expansion. COBRA (COB) has been identified previously as a
The crystal structure of the protein product of the gene locus At1g05000, a hypothetical protein from A. thaliana, was determined by the multiple-wavelength anomalous diffraction method and was refined to an R factor of 20.4% (R(free) = 24.9%) at 3.3 A. The protein adopts the alpha/beta fold found
ATM is a gene mutated in the human disease ataxia telangiectasia with reported homologues in yeast, Drosophila, Xenopus and mouse. Whenever mutants are available they all indicate a role of this gene family in the cellular response to DNA damage. Here, we present the identification and molecular
The Arabidopsisthaliana pathogenesis-related 1 (PR1) is an important defense protein, so far it has only been detected in extracellular space and its subcellular sorting and transport remain unexplained. Using a green fluorescent protein (GFP) tagged full length, as well as a C-terminus truncated
