Although the absence of seed set after intrapopulation crossings could be explained by general sterility, the ability to set seed successfully was demonstrated by our interpopulation crossing experiments in the greenhouse.
We performed quality control of STGG and gentamicin blood agar to ensure sterility and the ability to support pneumococcal growth.
Whilst these data have highlighted the potential usefulness of Raman spectroscopy in stem cell phenotyping, to date repeated measurements of the same cell population in long term culture have been precluded due to the need to maintain sterility, yet the ability to deliver this would be greatly advantageous when developing cell-based regenerative therapies.
Irradiation did not affect female fecundity but resulted in the production of sterile eggs, nor did it affect male insemination ability while ensuring sterility of sperm.
Hybrid behavioural sterility, characterized by a reduced ability of hybrids to perform necessary courtship behaviours, occurs in hybrids between two species of Nasonia.
In conclusion, while these hybrids may suffer from slightly reduced locomotor abilities, no behavioural sterility was observed.
Hybrid cultivars make use of male sterility to enhance the combining abilities of the parental lines, resulting in heterosis and significant increases in phenotypic traits such as yield, plant height and days to flowering (Reddy et al., 2006).
To generate the BC3 generation, we used 11 different Ma pollen donors that may differ in their ability to restore male sterility of Sp cytoplasm, which gave us an opportunity to examine possible variation of Rf in the Ma population.
Despite its ability to rescue female sterility, AOX expression produced no improvement in the developmental delay of sesB flies, consistent with the notion that this phenotype is, most probably, attributable to the limitation on ATP production that is imposed by sesB.
To explore the basis of the sterility phenotype, we examined the egg laying ability of M601 females.
