Australian sites that are claimed to preserve evidence of fossil spores and pollen for Late Neogene (Late Miocene, Pliocene) climates, mostly lack one or b... Macphail,K M. - 《Australian Journal of Botany》 被引量: 138发表: 1997年 Present market situation and prospects of meagre (Argyrosom...
The lower rate of the pod formation in transgenic lines, as compared to the wild-type, can be due to a down regulation of DGAT1 genes, which is reported to be important for the grain pollen formation11, but levels of DGAT1 in pollen were not measured in this study. The results of ...
Type I hypersensitivity, known as allergy or atopy, is mediated by IgE antibody specific for antigens that are normally non-pathogenic (allergens), such as plant pollens. In an atopic individual exposed to allergen, B cells produce allergen-specific IgE, which binds to FcεRs of mast cells...
Pollen fertility was inferred from stainability of pollen grain contents (Alexander, 1969). Counts were made under a light microscope (approximately 350 grains per count). Staining was in fact unnecessary because empty grains are much smaller than normal ones (18 versus 29 m) with hardly any ...

Another barrier is the cell wall of the pollen grain, which can be divided into three layers: an outer extine, an inner intine, and a lipid- and protein-rich pollen coat in the crevices of the extine. The extine is a multi-layered structure, primarily consisting of sporopollenin [36...

Cu deficiency reduces growth rates, seed set and yield due to impaired photosynthesis and pollen fertility. Cu also plays important roles in human health as an enzymatic cofactor involved in cellular respiration, free radical detoxification, pigmentation, neuron development, connective tissue formation ...
