12.
He does not suggest that the seeds of male sterility will be released into the wind by pollen from spermicidal corn.

In 1933 another important breeding technique, cytoplasmic male sterility ( CMS ), developed in maize, was described by Marcus Morton Rhoades.
14.
Cytoplasmic male sterility ( CMS ) is caused by the extranuclear genome ( mitochondria or chloroplast ) and shows maternal inheritance.
15.
The second scenario, known as epidemic dynamics, involves the arrival and loss of new cytoplasmic male sterility genes in new populations.
16.
Manifestation of male sterility in CMS may be controlled either entirely by cytoplasmic factors or by interaction between cytoplasmic and nuclear factors.
17.
However, in some species of plants, the male sterility genes win the battle over the nuclear fertility restoring genes, and gynodioecy occurs.
18.
:: Male sterility is a known side effect of radiation treatment of cancer but this not a safe alternative to vasectomy for contraception.
19.
In rye he started a systematic search for cytoplasmic male sterility in backcross generations of crosses between European and " exotic " rye accessions.
20.
In most plants, there are nuclear fertility restoring genes that counteract the work of the male sterility genes, maintaining the hermaphroditic state of the plant.
