Molecular marker systems for Oenothera genetics.
The genus Oenothera has an outstanding scientific tradition. It has been a model for studying aspects of chromosome evolution and speciation, including the impact of plastid nuclear co-evolution. A large collection of strains analyzed during a century of experimental work and unique genetic possibilities allow the exchange of genetically definable plastids, individual or multiple chromosomes, a...
متن کاملThe Genetics of Self-Incompatibility in Oenothera Organensis.
ENOTHERA organensis is endemic to the Organ Mountains of 0 southern New Mexico where the entire population apparently consists of considerably less than one thousand individuak2 The morphology of the seeds indicates a relationship to members of the subgenus Oenothera (sometimes called Onagra), but the growth habit and ovule placentation resemble types belonging to the subgenus Raimannia (the Eu...
متن کاملGrowing evening primroses (Oenothera)
The model plant Oenothera has contributed significantly to the biological sciences and it dominated the early development of plant genetics, cytogenetics, and evolutionary biology. The great advantage of using Oenothera as a model system is a large body of genetic, cytological, morphological, and ecological information collected over more than a century. The Oenothera system offers a well-studi...
متن کاملPneumoviruses: Molecular Genetics and Reverse Genetics
Pneumoviruses are responsible for significant respiratory disease in their hosts and represent a major problemfor human and animal health. Pneumoviruses are members of the family Paramyxoviridae, subfamilyPneumovirinae and the virus particles consist of a negative-sense, nonsegmented RNA genome within a helical nucleocapsid structure enveloped in a lipid membrane derived from the ho...
متن کاملTwin Hybrids of Oenothera Hookeri
The researches of MORGAN on lethal factors, of BARTLETT on mass mutation, and of RENNER on empty seeds, have led me of late to the conception that lethal factors and hybrid mutants play a large part in the splitting phenomena which accompany the normal mutations of so many species of Oenothera. The question, which part of those phenomena may be explained by this view, has to be faced. The cross...
