  • Publication number: 20210010011
    Abstract: Methods and compositions for improved bacterial-mediated plant transformation are provided. The methods generally allow plant transformation with reduced vector backbone integration and a high frequency of low-copy transformation events. Vectors for achieving these results are described, as are methods for their use.
    Type: Application

  • Publication number: 20190345507
    Abstract: The invention provides methods and compositions for identifying transgenic seed that contain a transgene of interest, but lack a marker gene. Use of an identification sequence that results in a detectable phenotype increases the efficiency of screening for seed and plants in which transgene sequences not linked to a gene of interest have segregated from the sequence encoding a gene of interest.

  • Patent number: 5923609
    Abstract: A wordline driver for a semiconductor memory array having a circuit for selecting and deselecting the first end of an addressed wordline and a circuit for deselecting the second end of the addressed wordline. The first and second ends of the addressed wordline are deselected at substantially the same time. The first end of the wordline is selected and deselected responsive to a strobe waveform and the second end of the wordline is deselected responsive to an RL Strobe waveform. The RL Strobe waveform is derived from a delayed strobe waveform.

  • Patent number: 5838168
    Abstract: An input buffer capable of operating at a first power supply voltage level or a second power supply voltage level with the operating voltage level selectable during manufacture. At least one shortable transistor is disposed between the power supply voltage input and a buffer circuit which is connected between an input and an output of the buffer circuit. When the first voltage is the intended operating voltage the at least one shortable transistor is shorted. The first operating voltage level meets the requirements of a CMOS device and the second operating voltage level meets the requirements of a TTL device. The shortable transistor can be either a p-channel or an n-channel transistor and the short can be done by a metal layer short, a polysilicon short, a depletion implant, or with vias during manufacture.
