Tissue distribution and deposition pattern of a cellulosic parenchyma-specific protein from cassava roots

RESUMO

A protein with a molecular mass of 22 kDa was purified from the cellulosic parenchyma of cassava roots. The amino acid composition of the protein was determined and antibodies generated against the purified protein were used to show that the concentration of the protein remains unchanged during root "tuber" formation. By using a tissue printing technique, as well as weatern blot, it was shown that the cellulosic parenchyma was the only root tissue in which the protein was deposited
