comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اولLocalization 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 کاملGreen sperm. Identification of male gamete promoters in Arabidopsis.
Previously, in an effort to better understand the male contribution to fertilization, we completed a maize (Zea mays) sperm expressed sequence tag project. Here, we used this resource to identify promoters that would direct gene expression in sperm cells. We used reverse transcription-polymerase chain reaction to identify probable sperm-specific transcripts in maize and then identified their be...
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 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...
