Localization 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 کاملExpression and localization of two anther-specific genes in the tapetum and microspore of Lilium longiflorum
Two stage-specific genes have been isolated from a subtractive cDNA library constructed from developing anthers of Lilium longiflorum. Tandem 5ˊand 3ˊ-rapid amplifications of cDNA ends with polymerase chain reaction (5ˊand 3ˊ-RACE-PCR) were used to obtain the full length cDNA sequences. The LLA89 cDNA contained an open reading frame of 303 bp encoding an acidic polypeptide of 100 amino acids wi...
متن کاملThe Role of Boron, Silicon and Nucleic Bases on Pollen Tube Growth of Lilium longiflorum (L.)
It is possible to obtain pollen germination and pollen tube growth in vitro if boric acid is present. In this work the effect was studied using as a semiquantitative parameter the mean length (J) o f Lilium longißorum pollen tubes. Pollen tube growth was examinated in depend ence on boric acid, ortho-silicic acid, nucleic bases, Ca2+ and Zn2+ in 10% sucrose solution. The maximum o f 7is obtain...
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 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 ...
