Abstract: The present invention provides a dual method for producing male-sterile plants. Two genetically transformed plants, parents 1 and 2 are crossed to obtain male-sterile offspring. Parent 1 is transformed with an expression cassette comprising a nucleotide sequence encoding an anther-specific promoter which is operably linked to a nucleotide sequence encoding a transactivator. Parent 2 is transformed with an expression cassette comprising a target nucleotide sequence, which is capable of being activated by the transactivator, operably linked to a nucleotide sequence which encodes RNA or a polypeptide which will disrupt the formation of viable pollen. Therefore, crossing parent 1 with parent 2 results in male-sterile offspring. The male-sterile plants are useful for producing hybrid seed.The invention also provides compositions and methods for high level expression of a coding region of interest in a plant.

Abstract: Gene activating sequences which activate the expression of other bacterial genes, which are latent or expressed at low levels, are provided. The gene activating sequences confer the ability to produce several metabolites and may be transferred to bacterial strains. The transformed biocontrol agents are active to inhibit the growth of the fungal pathogens.

Abstract: A scanning radio receiver intended for use on the frequencies assigned to the Public Safety Radio Services and which is also operable for reception in the aircraft band from 118 MHz to 136 MHz. A ROM contains data establishing frequency limits and other information such that frequencies assigned to a number of service categories can be automatically searched in response to operation of service keys of a keyboard with the information storage requirements being minimized. For a service band having single frequencies or groups of frequencies which are not separated by fixed frequency increments, the data identifies the number of such frequencies or groups, the number of frequencies in each and a limit frequency of each. A processor outputs a frequency code to a frequency synthesizer while also processing input and stored data to develop the next code to be output.
