Incompatibility studies in Oenothera

The 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...

Investigation of interspecific genome-plastome incompatibility in Oenothera and Passiflora

Self-incompatibility system of Oenothera organensis for the detection of genetic effects at low radiation doses.

The self-incompatibility system of Oenothera organensis is used to analyze the frequency of S locus mutations induced by low doses (2.5-20 rad) of fast neutrons and x-rays. Th principles and methods of the screening system for detection of low dose effects have been presented. The results show that low doses induced significantly higher frequencies of seeds and seedlings than those produced spo...

The Incompatibility Mechanism of the Biennis Group I Races of Oenothera.

EARLY all of the North American euoenotheras east of the Rocky Mountains Nremain heterozygous generation after generation even though they have the self-pollinating habit. A specialized cytogenetic mechanism involving multiple reciprocal translocations and a balanced lethal system accounts for this paradox. These Oenotheras possess 14 chromosomes of which each set of seven, because of reciproca...

In a multidatabase system schematic con icts between two objects are usually of inter est only when the objects have some semantic a nity In this paper we try to reconcile the two perspectives We rst de ne the concept of semantic proximity and provide a semantic taxonomy We then enumerate and classify the schematic and data con icts We discuss possible semantic similarities between two objects ...
