POLY SACCHARIDE BIOSYNTHESIS DURING CELL GROWTH AND DIFFERENTIATION OF PEA PISUM-SATIVUM CULTIVAR ALASKA ROOT TIPS

The present investigation is concerned with the pattern of incor­poration of radioactivity from D-U 14C glucose into the total sugars of the polysaccharides synthesized in different regions of pea root-tips. The results show an excellent example of meta­bolic and biochemical differentiation in which the biosynthetic pathways are continuously modulated at cellular level as growth and differentiation proceeds.
