Coexpression of * and Genes Contributes to High Glyphosate Tolerance and Low Glyphosate Residues in Transgenic Rice.

Weeds are one of the main factors that affect the yield and quality of rice. The combination of glyphosate-resistant transgenic crops and glyphosate is regarded as an important strategy for weed management in modern agriculture. In this study, a codon-optimized glyphosate oxidase gene from a variant BceGO-B3S1 and a glyphosate-tolerant gene from the bacterium were transformed into an .

Development and analysis of a longitudinal and torsional type ultrasonic motor with two stators.

In this paper, a new longitudinal and torsional type ultrasonic motor with two stators is presented and investigated. Normally, such a motor consists of one rotor and one stator, and two types of transducers that are longitudinal PZT and torsional PZT are used to generate the desired elliptical locus on the stator surface. The operating frequency is at the resonance frequency of torsional transducer.
