Phytic 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 کاملCharacteristics of the Tetraploid Plant Derived as a Somaclonal Variation in Lilium longiflorum
Somaclonal variation that possibly occurs during the process of plant tissue culture is considered to provide a source of new germplasm. Polyploidy is one of the most frequent incidents among the somaclonal variations. In the present study, we performed cytological and morphological characterization of tetraploid plants that were obtained from long-term subcultured callus culture of Lilium long...
متن کاملpH gradients are not associated with tip growth in pollen tubes of Lilium longiflorum.
The cytoplasmic pH of growing pollen tubes of Lilium longiflorum Thunb. was measured using the pH-sensitive fluorescent dye 2',7'-bis-(carboxyethyl)-5(6')-carboxyfl uorescein and confocal fluorescence ratio imaging. The average cytoplasmic pH in the clear zone of the pollen tube tip was pH 7.11, and no consistent pH gradients were detected in the clear zone, averaging around -1.00 milli pH unit...
متن کاملLocalization of Phosphorus and Cation Reserves in Lilium longiflorum Pollen.
Transmission electron microscopy of pollen from Lilium longiflorum Thunb. reveals electron-dense inclusions in storage body organelles ubiquitous in the cytosol. In ungerminated pollen, these inclusions are rounded in appearance and appressed to the inner surface of the smooth membrane of the storage body. During pollen germination, these inclusions become less rounded, smaller, and enclosed in...
متن کاملA Calcium-Activated Phytase from Pollen of Lilium longiflorum.
A phytase was isolated and partially purified from the pollen of Lilium longiflorum Thumb. Optimum activity was at pH 8.0. The phytase was activated by Ca(2+) and Sr(2+) but not by the other divalent cations tested. Activity was inhibited by ethylenediaminetetraacetate. The phytase had a temperature optimum of 55 to 60 degrees C and an activation energy of about 12,700 calories/mole. Extraction...
