The mechanism of floral organ specification is principally conserved in angiosperms, as demonstrated by the ABC model. By contrast, mechanisms that regulate the development of organs or structures specific to a group of species remain unclear. Grasses have unique inflorescence units, comprising spikelets and florets. In the genus Oryza (rice), the single spikelet consists of a fertile floret su...

The sterile insect technique may be implemented to control populations of the oriental fruit fly, Bactrocera dorsalis (Hendel) (Diptera: Tephritidae), when environmental concerns preclude widespread use of chemical attractants or toxicants. The goal of the present study was to evaluate whether the mating competitiveness of sterile B. dorsalis males could be increased via pre-release feeding on ...

A new type of hybrid sterility was investigated in D. melanogaster . Matings between strain 27 males from Para Wirra, South Australia, and Canton-S females produce 70-80% fully sterile male and female progeny. Strain 27 males produce sterile progeny when crossed to females of other geographic origins, but produce fertile progeny when crossed to a second sympatric strain. The sterility is avoide...

Leslie, J. F. 1983. Some genetic techniques for Gibberella zeae. Phytopathology 73:1005-1008. Gibberella zeae, an important plant pathogen, is exploited commercially dependent, glutamate dehydrogenase-deficient mutant. Protoplasts were in the production of zearalenone, a fungal sex hormone. Genetically, G. liberated by hyphal digestion with commercially available f-glucuronidase zeae is relativ...
