Localization of ATPase in sink tissues of Ricinus
1986
Didehvar, F. | Baker, D.A.
Histochemical localization of ATPase was carried out on phloem tissues from vegetative and reproductive sinks of Ricinus communis, using lead precipitation procedures. Reaction products were localized mainly at the plasma membrane of the sieve elements, companion cells and phloem parenchyma cells. Activity was also present in plasmodesmata, the tonoplast of companion cells and dispersed P-protein within the sieve element lumen. The results are discussed in relation to the possible involvement of a plasma membrane ATPase in apoplastic and symplastic unloading from the phloem conducting tissues.
