Genetics of gametophyte development
Published online by Cambridge University Press: 05 December 2011
Synopsis
Fern gametophytes provide unique opportunities for the investigation of various aspects of physiology, genetics and development. Past genetic studies of gametophytes have primarily involved investigations of variegation and radiation-induced plastid aberrations. Two studies have utilised the gametophyte generation to develop screens for specific types of mutations. The considerable natural variation that exists in gametophyte development has not been investigated genetically. Genetic studies can provide needed information regarding basic aspects of development. A selection system with broad applicability has been developed to isolate gametophyte mutations that confer resistance to growth regulators. An example of the use of the screen with abscisic acid is given and preliminary characterisations of some of the mutants are presented.
