We have explored methods to achieve excellent results in study of the pollen grain wall by using only one electron microscope, the scanning electron microscope (SEM). While the secondary electron imaging mode , the most common in use, has great value in characterizing the exine surface it is possible to obtain a more comprehensive representation of pollen grain walls by expanding the capability...

The diversity of pollinating insects is used as conservation management. Pollen gametophyte from male which can give characteristics to its offspring. pollen carried by bees be an identification feed favored bees. This study aims identity derived the legs stingless based on color morphological pollen. methods include collected bees, extraction, acetolysis, and identification. with same species ...

The external pollen morphology of the family Sapotaceae in Thailand was examined using acetolysis method to determine its taxonomic significance. Pollen 39 specimens belonging 32 species investigated by means light and scanning electron microscopy. grains are found be monads, isopolar, colporate, lalongate, variable size, shape, aperture number, colpus length exine thickness. Exine ornamentatio...

Chlorella protothecoides has been put forth as a promising candidate for commercial biodiesel production. However, the cost of biodiesel remains much higher than diesel from fossil fuel sources, partially due to the high costs of oil extraction from algae. Here, we identified the presence of a sporopollenin layer outside the polysaccharide cell wall; this was evaluated using transmission electr...

The extent of protein N-glycosylation in Leishmania mexicana amazonensis has been proposed to be a factor in the virulence of the parasite. The N-linked oligosaccharides of gp63, the major surface glycoprotein of L. mexicana amazonensis, were characterized after their release by hydrazinolysis, re-N-acetylation, and reduction with NaB3H4. High voltage paper electrophoresis of the reduced oligos...
