The cell wall is the major limiting factor for plant growth. Wall extension is thought to result from the loosening of its structure. However, it is not known how this is coordinated with wall synthesis. We have identified two novel allelic cellulose-deficient dwarf mutants, kobito1-1 and kobito1-2 (kobi-1 and kobi-2). The cellulose deficiency was confirmed by the direct observation of microfibrils in most recent wall layers of elongating root cells. In contrast to th...

Cellulose Synthesis in Phytophthora infestans Pathogenesis
Plant Cell ; Plant pathogens breach the plant cell to reach the nutrients within and yet must also avoid detection by the plant defenses (reviewed in Huckelhoven, 2007). During infection, fungal and oomycete pathogens make new cell wall and at the same time break down the host cell wall. First, the pathogen
Impairment of Cellulose Synthases Required for Arabidopsis Secondary Cell Wall Formation Enhances Disease Resistance(W)
Plant Cell ; Cellulose Is synthesized by cellulose syntheses (CESAs) contained in plasma membrane-localized complexes. In Arabidopsis thaliana, three types of CESA subunits (CESA4/IRREGULAR XYLEMS [IRX5], CESA7/IRX3, and CESA8/IRX1) are required for secondary cell wall formation. We report that mutations in
An Arabidopsis Endo-1,4-[beta]-D-Glucanase Involved in Cellulose Synthesis Undergoes Regulated Intracellular Cycling[W]
Plant Cell ; The synthesis of cellulose microfibrils requires the presence of a membrane-bound endo-1,4946;-D-glucanase, KORRIGAN1 (KOR1). Although the exact biochemical role of KOR1 in cellulose synthesis is unknown, we used the protein as a marker to explore the potential involvement of subcellular transport
Three distinct rice cellulose synthase catalytic subunit genes required for cellulose synthesis in the secondary wall1
Plant Physiology ; Several brittle culm mutations of rice (Oryza sativa) causing fragility of plant tissues have been identified genetically but not characterized at a molecular level. We show here that the genes responsible for three distinct brittle mutations of rice, induced by the insertion of the endogenous
Cellulose Synthesis in Phytophthora infestans Is Required for Normal Appressorium Formation and Successful Infection of Potato(W)
Plant Cell ; Cellulose, the important structuralcompound of cell walls, provides strength and rigidity to cells of numerous organisms. Here, wefunctionally characterize four cellulose synthase genes (CesA) in the oomycete plant pathogen Phytophthora infestans, the causal agent of potato (Solanum tuberosum) late
