WebOct 1, 2000 · It is possible that linkage specificity is determined by subtle features in the active site of the proteins ( Stasinopoulos et al., 1999) and that members of the Arabidopsis cellulose synthase superfamily make polysaccharides with both β- and α-linkages. Table I. Identity/similarity matrix for selected members of the CesA superfamily. Identity. WebFeb 25, 2012 · Cellulose synthase catalytic subunits (CesAs) are the catalytic sites within a multisubunit complex for cellulose biosynthesis in plants. CesAs have been extensively studied in diploid plants, but are not well characterized in polyploid plants. Gossypium hirsutum is an allotetraploid cotton species producing over 90% of the world's cotton fibers.
Cloning and characterization of homeologous cellulose synthase ...
WebCESA1 (Cellulose synthase A catalytic subunit 1) is required during embryogenesis for cell elongation, orientation of cell expansion and complex cell wall formations, such as interdigitated pattern of epidermal pavement cells, stomatal guard cells and trichomes. CESA1 plays a role in lateral roots formation, but seems not necessary for the ... WebApr 10, 2024 · In bacteria, the cellulose synthase complex, called Bcs, takes the shape of a linear protein complex built around BcsA, whereas in plants it is arranged in a rosette made of six trimers of CesA proteins ( Figures 1 and 2 C). However, many different CesA complex organizations are observed in algae, including rosettes, linear single rows, linear ... toole and powers portland maine
