Primary wall cellulose synthase regulates shoot apical meristem mechanics and growth

Abstract

How organisms attain their specific shapes and modify their growth patterns in response to environmental and chemical signals has been thesubject ofmany investigations. Plant cells are at high turgor pressure and are surrounded by a rigid yet flexible cell wall, which is the primary determinant of plant growth and morphogenesis. Cellulose microfibrils, synthesized by plasma membrane-localized cellulose synthase complexes, are major tension-bearing components of the cell wall thatmediate directional growth. Despite advances in understanding the genetic and biophysical regulation of morphogenesis, direct studies of cellulose biosynthesis and its impact onmorphogenesis of different cell and tis..
