| | Marin CNPS: Flower Parts: The Anther |
| | The anther is the terminal part of the stamen and produces the pollen which is responsible for fertilizing the female part of a flower. | | | The anther is connected to the rest of the flower by a stalk called a filament. | | | The stamen is the male reproductive structure of the flower. |

| | Jeffrey K. Conner - Detailed Research Description |
| | Since the insect pollinators remain in the open part of the corolla, flowers with anthers that are placed too high or two low may not be as successful at placing their pollen on insects as flowers with intermediate anther placement. | | | As we did for anther exsertion in 2001, the composite population formed from the selected and control lines was placed in the field in the summer of 2002 to measure selection with this increased variation in anther exsertion; results await completion of microsatellite paternity analysis. | | | Since anther position should mainly affect male fitness, that is, the ability to sire seeds on other plants, measurements of male success were necessary. |

| | Title of Invention: Isolated microspore and anther culture of corn |
| | The seed may be derived by well-established techniques of harvesting from mature plants or by replanting the harvested seed and obtaining seed from descendant plants. | | | Anther culture responsiveness in corn varies with the genotype of the source plant. | | | When anthers were cold shocked for 14 days prior to introducing them into culture (Genovesi and Collins 1982), one class of anthers, when removed from the cold, became puffed in appearance, light yellow, and easily dehisced their contents when touched with forceps. |

| | The results show that numerous large starch grains are present in the cells of the anther wall and filaments in space plants, while starch grains are rarely observed in those cells of the ground plants. | | | The results suggest that despite the storage of starch grains in the anther wall and the persistence of tapetum, the nutrients necessary for pollen development were supplied in microgravity. | | | Anthers from those flowers were processed and prepared for light and electron microscope observation. |

| | Title of Invention: Increasing the anther culturabi lity of maize |
| | Anther culture involves isolating immature anthers from plants and placing them onto a medium which induces the cells within the anther, which would normally be destined to become pollen grains, to begin dividing and form a cell culture from which plants can be regenerated. | | | Specifically in maize, anther culturable plants are very useful in the development of human food, livestock feed, and as a raw material in industry. | | | Tassels with anthers containing microspores at the late uninucleate-early binucleate state of development, as determined microscopically after treatment with acetocarmine, were removed from donor plants prior to emergence from the whorl. |

| | Aside from field evaluation, an accurate means to test the existence of gametic selection occurring during the androgenetic pathway is the comparative study of segregations of genetic markers among both sexual (F2 or backcrossed plants) and anther culture derivatives. | | | In cultivated rice (Oryza sativa L.), the isozyme loci appear to be suitable markers for this purpose because of their high level of polymorphism in distantly related varieties (Glaszmann 1987) and their wide expression in anther culture derivatives (Guiderdoni et al. | | | Comparative gametic selection in sexual and anther culture derivatives from five distant F1 hybrids of rice |
