Chloride fluxes in lily pollen tubes: a critical reevaluation.
Microelectrodes, made from a Cl(-)-selective liquid ion exchanger previously used to measure putative Cl- fluxes in Lilium longiflorum pollen tubes, were characterized. The electrodes were poorly selective, possessing only about 10-fold selectivity for Cl- over other anions tested. They had only 2.4-fold selectivity for Cl- over the anionic form of the H+ buffer, MES, indicating that the electr...
متن کاملA unique caleosin in oil bodies of lily pollen.
In view of the recent isolation of stable oil bodies as well as a unique oleosin from lily pollen, this study examined whether other minor proteins were present in this lipid-storage organelle. Immunological cross-recognition using antibodies against three minor oil-body proteins from sesame suggested that a putative caleosin was specifically detected in the oil-body fraction of pollen extract....
متن کاملPhytic Acid Metabolism in Lily (Lilium longiflorum Thunb.) Pollen.
The accumulation of phytic acid during development of lily (Lilium longiflorum Thunb.) pollen and its degradation during germination have been studied. A substantial amount of phytic acid accumulates in lily pollen by 5 days before anthesis, and little change occurs during subsequent maturation. Mature lily pollen contains 7 to 8 micrograms phytic acid per milligram pollen. Considerable degrada...
متن کاملLost in traffic? The K+ channel of lily pollen, LilKT1, is detected at the endomembranes inside yeast cells, tobacco leaves, and lily pollen
Fertilization in plants relies on fast growth of pollen tubes through the style tissue toward the ovules. This polarized growth depends on influx of ions and water to increase the tube's volume. K(+) inward rectifying channels were detected in many pollen species, with one identified in Arabidopsis. Here, an Arabidopsis AKT1-like channel (LilKT1) was identified from Lilium longiflorum pollen. C...
متن کاملOral immunization of mice with lily pollen expressing HBsAg.
Lily pollen was developed to express HBsAg by Agrobacterium-mediated transformation. A double prime-boost strategy combining parenteral and oral HBsAg boosters was found to increase antibody titer levels 10-fold, as compared to a single process of priming and boosting. Lily pollen may prove a tool for oral vaccine development.
