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 کاملCytoplasmic changes accompanying the female meiosis in Lilium longiflorum Thunb.
The events that accompany female meiosis in Lilium parallel almost exactly those characteristic of male cells. The megaspore mother-cell is first cut off from investing tissue by a callosic wall, and this isolated cytoplasm undergoes a phase of comprehensive dedifferentiation. Not only does the major part of the ribosome population appear to be removed from both the cytoplasm and plastids, but ...
متن کاملVariability in flower development of Easter lily (Lilium longiflorum Thunb.): model and decision-support system
A model to predict the distribution of harvest dates in an Easter lily crop was validated using data from several locations. Plants were individually harvested (i.e. removed from the greenhouse for shipping) when flowers on a plant reached a minimum flower bud length. A computer decision-support system called LilyDate was developed to allow the model to be used to optimize greenhouse temperatur...
متن کاملEctopic expression of LLAG1, an AGAMOUS homologue from lily (Lilium longiflorum Thunb.) causes floral homeotic modifications in Arabidopsis.
The ABC model for floral development was proposed more than 10 years ago and since then many studies have been performed on model species, such as Arabidopsis thaliana, Antirrhinum majus, and many other species in order to confirm this hypothesis. This led to additional information on flower development and to more complex molecular models. AGAMOUS (AG) is the only C type gene in Arabidopsis an...
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...
