Allergenic pollen and pollen allergy in Europe
Allergy, 2007 The allergenic content of the atmosphere varies according to climate, geography and vegetation. Data on the presence and prevalence of allergenic airborne pollens, obtained from both aerobiological studies and allergological investigations, make it possible to design pollen calendars with the approximate flowering period of the plants in the sampling ...

Nature Communications, 2022 Atmospheric conditions affect the release of anemophilous pollen, and the timing and magnitude will be altered by climate change. As simulated with a pollen emission model and future climate data, warmer end-of-century temperatures (4–6 K) shift the ...

Anthropogenic climate change is worsening North American pollen seasons
Proceedings of the National Academy of Sciences of the United States of America, 2021 Significance Human-caused climate change could impact respiratory health, including asthma and allergies, through temperature-driven increases in airborne pollen, but the long-term continental pollen trends and role of climate change in pollen patterns ...

Bee Pollen: Current Status and Therapeutic Potential
Nutrients, 2021 Bee pollen is a combination of plant pollen and honeybee secretions and nectar. The Bible and ancient Egyptian texts are documented proof of its use in public health.

Downy mildew resistance and genetic variability in a wild rocket germplasm collection
Agronomy Journal, Volume 114, Issue 6, Page 3083-3095, November/December 2022., 2022 Abstract One hundred accessions of a “core collection” of Diplotaxis tenuifolia (L.) DC. and Eruca spp. were screened at seedling stage for resistance to downy mildew. Accessions tested at the seedling stage were assigned to 0–6 interaction phenotypes.

Proceedings of the National Academy of Sciences of the United States of America, 2021 Significance Coexposure to airborne pollen enhances susceptibility to respiratory viral infections, regardless of the allergy status. We hypothesized this could be also true for SARS-CoV-2 infections.

Does agroecosystem management mitigate historic climate impacts on dryland winter wheat yields?
Agronomy Journal, Volume 114, Issue 6, Page 3515-3530, November/December 2022., 2022 Abstract Global studies that quantify climate effects on crop yields using top‐down spatial frameworks are invaluable for assessing generalized effects on world food supplies, yet do not contain the resolution necessary to identify local mediating effects of management. Our objectives were to identify (a) what climate factors have historically affected

Pollen and Pollen Enzymes [PDF]
American Journal of Botany, 1921 A review of the literature shows very few complete or satisfactory reports of experiments in regard to either the general chemistry or the enzymes of pollen. Our knowledge of the subject seems to be very fragmentary. It is conspicuous by its omission from the textbooks of botany.

Pollen limitation of native plant reproduction in an urban landscape
American Journal of Botany, Volume 109, Issue 12, Page 1969-1980, December 2022., 2022 Abstract Premise Evidence suggests that bees may benefit from moderate levels of human development. However, the effects of human development on pollination and reproduction of bee‐pollinated plants are less‐well understood. Studies have measured natural variation in pollination and plant reproduction as a function of urbanization, but few have ...

Pollen biology and hormesis: Pollen germination and pollen tube elongation
Science of The Total Environment, 2021 This paper evaluated the occurrence of hormetic dose responses in pollen reported over the past eight decades. Hormetic doses responses were induced by a wide range of chemical and physical agents in 34 plant species for pollen germination and pollen tube growth/elongation.
