In plant organs and tissues, the neutral storage lipids are confined to discrete spherical organelles called oil bodies. Oil bodies from plant seeds contain 0.6-3% proteins, including oleosins, steroleosins, and caleosins. In this study, a caleosin isoform of approximately 30 kDa was identified in the olive pollen grain. The protein was mainly located at the boundaries of the oil bodies in the ...

A radiocarbon chronology has been developed using shell, bulk peat, and paired charcoal and pollen preparations from a peat and clay sequence in southwestern Australia. The results indicate the sequence is of Holocene age, and the mid-Holocene was a period of rapid sediment deposition. The earliest record is based on Bothriembyron sp. snail shell and there is a strong indication that the deposi...

The use of pollen from the Masson Pine (Pinus massoniana) in the traditional Chinese medicine has a long history and its medical application was already mentioned in the earliest Chinese pharmacopeias written during the Tang and Ming dynasty (LI, 1978; SU, 1957). Up to now, one of the main application fields of the artificially sampled pollen is the cure of chronic constipation, especially in o...

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....

abstract: mostly honey bee consumes pollen as fermented and fermentation improves foods biological value in some cases.  in this study we evaluate the nutritional effects of fermented diets on honey bee body protein and brood rearing in colonies. this experiment conducted on honey bee colonies with different diets in a completely randomized design with 6 treatments and 7 replicates for 50 days....

A study was conducted to investigate the effect of different storage periods and temperatures on pollen viability in vitro vivo plum genotypes ‘Valerija’, ‘?a?anska Lepotica’ ‘Valjevka’. In tested at day 0 (fresh dry pollen) after 3, 6, 9 12 months four (4, ?20, ?80 ?196 °C), distinct temperatures. germination fluorescein diacetate (FDA) staining methods were used test viability, while aniline ...
