INDUCED TETRAPLOIDS OF A SELF STERILE OENOTHERA

Induced Tetraploids of a Self Sterile Oenothera.

Oenothera Plastome Mutator-Induced Chloroplast Mutant1

Plastids were isolated from a plastome mutator-induced mutant (pm7) of Oenothera hookeri and were analyzed for various physiological and biochemical attributes. No photosynthetic electron transport activity was detected in the mutant plastids. This is consistent with previous ultrastructural analysis showing the absence of thylakoid membranes in the pm7 plastids and with the observation of aber...

Recovery of Ancestral Tetraploids

Methods to recover an ancestral pre-duplicated genome giving rise to a minimal number of genomic rearrangements. Rearrangement operations considered are reversals and translocations. We obtain exact algorithms running in polynomial time.

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...
