2024年5月28日,南京农业大学万建民院士团队在Nature Communications在线发表了题为“OsSRF8 interacts with OsINP1 and OsDAF1 to regulate pollen aperture formation in rice”的研究论文,揭示了OsINP1-OsSRF8-OsDAF1分子模块调控水稻花粉萌发孔形成的分子机制。
A Cornell-developed technology provides beekeepers, consumers and farmers with an antidote for pesticides, some of which may kill wild bees and can contribute to beekeepers losing around a third of th...
One of the best sources of information on the evolution of terrestrial ecosystems and plant diversity over millions of years is fossil pollen. For palynologists -- the scientists who study ancient pol...
Reduced resilience of plant biomes in North America could be setting the stage for the kind of mass extinctions not seen since the retreat of glaciers and arrival of humans about 13,000 years ago, cau...
Springtime rains can be a surprising source of pollen, according to research supported by the National Science Foundation.University of Iowa researchers report that tree pollen fragments remain in the...
Like seeds, pollen loses most of its water during maturation, entering a state of suspended animation. This allows it to survive its journey from male to female organs of a flower, where it is rehydra...
Rac/Rop GTPases are molecular switches in plants that control the growth of polarized cells such as pollen tubes and root hairs, differentiation, development, actin dynamics, production of reactive ox...
Simulating pollen concentrations with numerical weather prediction (NWP) systems requires a parameterization for pollen emission.
Pollen tube growth, the process that transports the sperm cell to the ovule, is fundamental for plant sexual reproduction. The actin cytoskeleton is essential to the process of pollen tube elongation....
The prevalence of allergic disease is expected to increase with climate change. Grasses, which have highly allergenic pollen, are widely distributed across the globe. Changes in production and allerge...
We did a comparative analysis of pollen and spores from five kinds of natural pollen traps at Wenbi Reservoir, northwest Yunnan, China. The natural traps were the surface soil, ground inhabiting mosse...
The biomisation method is used to reconstruct Latin American vegetation at 6000±500 and 18 000±1000 radiocarbon years before present (14C yr BP) from pollen data. Tests using modern pollen data from 3...
Pollen-based climate reconstructions were performed on two high-resolution pollen marines cores from the Alboran and Aegean Seas in order to unravel the climatic variability in the coastal settings of...
High-temporal resolution pollen record from the Alboran Sea ODP Site 976, pollen-based quantitative climate reconstruction and biomisation show that changes of Mediterranean vegetation have been clear...
New detailed vegetation reconstructions are proposed in Atlantic Central Africa from a modern pollen data set derived from 199 sites (Cameroon, Gabon and Congo) including 131 new sites. In this study...
