Hygroscopic weight gain of pollen grains from Juniperus species.
Juniperus pollen is highly allergenic and is produced in large quantities across Texas, Oklahoma, and New Mexico. The pollen negatively affects human populations adjacent to the trees, and since it can be transported hundreds of kilometers by the wind, it also affects people who are far from the source. Predicting and tracking long-distance transport of pollen is difficult and complex. One para...
متن کاملPredicting and Quantifying Pollen Production in Juniperus Ashei Forests
Juniperus ashei pollen has been reported as a major airborne allergen in regions of Texas and Oklahoma. Pollen production across these populations was examined in order to support a pollen forecast system. Four locations in Texas and 2 locations in Oklahoma were chosen as study sites. Trees in each location were measured, cone production was evaluated based on a rating system, and percent tree ...
متن کاملPollen and Pollen Tube Proteomics
Germinated pollen grains form pollen tubes that accomplish rapid polarized growth within female gametophytic tissues in order to deliver the sperm cell to the ovule. This process is essential for successful plant fertilization in vivo. Pollen tubes are considered to be an ideal model system to study tip growth. A more comprehensive understanding of proteins involved in pollen development, germi...
متن کاملPollen sporoplasts: dissolution of pollen walls.
4-Methylmorpholine N-oxide monohydrate (MMNO.H(2)O), a potent solvent for polysaccharides, is an effective vehicle for release of membrane-enclosed male gametophytes (sporoplasts) from spore walls. This release occurs in minutes when pollen (Lilium longiflorum Thunb.) is suspended in a melt of MMNO.H(2)O at 75 degrees C. Continued heating at 75 degrees C leads to distintegration of the exine ;s...
متن کاملPollen
Does cohesion fatigue play a role in the ‘maternal age effect’? The frequency of aneuploid conceptions in humans increases strikingly with maternal age, approaching 35% for women in their 40s. Remarkably, if studies of mouse oocytes are applicable to humans, it appears that the actual cohesin molecules that bind chromatids together in the oocytes of women may be decades old. In mammals, S phase...
