Pollen and plant reproduction biology: blooming from East to West.
The idea of assembling a Special Issue on Pollen Tube and Reproduction in Molecular Plant was conceived during the organization of the 2012 Pollen Biology International Symposium and Workshop held at the Shanghai Institute of Plant Physiology and Ecology (SIPPE), Chinese Academy of Science (CAS), 27–31 October 2012. Wei-Hua Tang of the SIPPE led the organization, with the support of Hong-Wei Xu...
متن کاملThe remarkable biology of pollen.
To reproduce, higher plants utilize a unique multicellular microorganism: the male gametophyte, or pollen grain. The independent lifetime of flowering plant gametophytes is greatly abbreviated compared to that of gametophytes of more primitive plants, yet the angiosperm pollen grain must be able to survive at least briefly free from the sporophytic plant and perform a number of specialized func...
متن کاملPlant Fertilization: Bursting Pollen Tubes!
Higher plants don't have motile sperm; they rely on pollen tubes to deliver them. Recent research has identified key components involved in pollen tube tip bursting that allow sperm release and fertilization.
متن کاملLong-distance GM pollen movement of creeping bentgrass using modeled wind trajectory analysis.
The importance of understanding the role of atmospheric conditions in pollen dispersal has grown in recent years with increased field-testing of genetically modified (GM) crop plants. An atmospheric model was used to characterize wind trajectories at 10 m and 100 m above GM pollen source fields located within a 4452-ha "control" area north of Madras, Oregon, USA, designated by the Oregon Depart...
متن کاملPollen-mediated gene flow from transgenic perennial creeping bentgrass and hybridization at the landscape level
The planting of 162 ha of transgenic glyphosate-resistant creeping bentgrass (Agrostis stolonifera) near Madras, OR, USA, allowed a unique opportunity to study gene flow over time from a perennial outcrossing species at the landscape level. While conducting a four year in situ survey, we collected panicles and leaf tissue samples from creeping bentgrass and its sexually compatible species. Seed...
