Specific Labeling Of Rosette

According to preliminary western blot analysis, the antibody to the recombinant cellulose synthase recognized an antigen of 130kd from three vascular plants - cotton, Arabidopsis and Vigna radiata. These results suggest that the catalytic subunit is conserved among a number of vascular plants. The antibody also recognized proteins obtained from cotton fibers during primary and secondary wall development. The specific labeling of rosette TCs on the P-fracture face of plasma membrane by the CesA...

The Properties Of Wood

Xylogenesis Wood Fiber Cells

Trees are nature's largest and longest living organisms and, like all plants, cannot escape any environmental challenges. They have therefore evolved a survival strategy based on metabolic flexibility, sturdy cells and efficient transportation of metabolites between roots and leaves, which can be over 100 meters apart. The canopy of a tree carries the leaves, which are its carbohydrate factory, while the long trunk serves to hold the leaves above other plants to win the competition for light...

Substrate Supply For Cotton Fiber Cellulose Biogenesis

Cotton Fiber Synthesis

Substantial evidence implicates UDP-Glc as the immediate substrate for cellulose polymerization in vascular plants including cotton fiber Franz 1969 Carpita and Delmer 1981 . UDP-Glc was the most abundant nucleotide in the fiber and its concentration increased in parallel with stage-specific increases in the cellulose synthesis rate 0.2, 1.2, and 2.1 imol boll at 13, 17, and 21 DPA, respectively. The UDP-Glc for cellulose synthesis could be supplied by 1 sucrose synthase SuSy E.C. 2.4.1.13 Suc...
