Cytochemical detection of ATPase activity in the pollen grain (PG) and pollen tube (PT) of Agapanthus umbelatus showed that the enzymes concerned presented specific patterns of membrane distribution according to their ionic dependencies and to the timecourse of germination and tube growth. In the pollen tubes Ca2+-ATPases were mainly localized in mitochondria and ER membranes, while Mg2+-ATPases were found especially in the tonoplast and in the membrane of the P-particles. K+-ATPases showed a… CONTINUE READING
