  • Publication number: 20210230563
    Abstract: The present invention relates to a mutant p-hydroxyphenylpyruvate dioxygenase (HPPD) protein or a bioactive fragment thereof and an isolated polynucleotide comprising a nucleic acid sequence encoding the protein or fragment thereof, wherein the mutant p-hydroxyphenylpyruvate dioxygenase (HPPD) protein or a bioactive fragment thereof retains or enhances the property of catalyzing the conversion of p-hydroxyphenylpyruvate (HPP) to homogentisate and is significantly less sensitive to HPPD-inhibiting herbicides than a wild-type HPPD. The present invention also relates to a nucleic acid construct, an expression vector and a host cell comprising the polynucleotide, as well as to a method for producing a plant that has the property of catalyzing the conversion of p-hydroxyphenylpyruvate (HPP) to homogentisate and significantly reduced sensitivity to HPPD-inhibiting herbicides.

  • Publication number: 20210141358
    Abstract: A detection system based on a zero-point real-time refreshing calculation for real-time rotation measurement, includes an analog quantity sensor and a programmable logic controller (PLC). The detection system based on the zero-point real-time refreshing calculation for real-time rotation measurement further includes a storage unit and a display. The storage unit includes three common storage units. An output port of the analog quantity sensor is connected to an input port of the PLC by a data cable, and an output port of the PLC is connected to an input port of the display by a data cable. At a zero point of each sampling segment, a signal at a previous moment is acquired and then subjected to an operation to thereby obtain a real-time rotation speed and a quantity of rotations at a current moment.

  • Publication number: 20190203224
    Abstract: The subject invention relates in part to Cry34Ab/35Ab in combination with Cry3Aa. The subject invention relates in part to the surprising discovery that combinations of Cry34Ab/Cry35Ab and Cry3Aa are useful for preventing development of resistance (to either insecticidal protein system alone) by a corn rootworm (Diabrotica spp.) population. As one skilled in the art will recognize with the benefit of this disclosure, corn plants producing these insecticidal Cry proteins will be useful to mitigate concern that a corn rootworm population could develop that would be resistant to either of these insecticidal protein systems alone. Plants (and acreage planted with such plants) that produce these two insecticidal protein systems are included within the scope of the subject invention.
