Patent number: 11124800Abstract: Ascorbate protects tissues against damage caused by reactive oxygen species (ROS) produced through normal metabolism or generated from stress. The inositol route to AsA involves four enzymes: myo-inositol oxygenase, glucuronate reductase, gluconolactonase (GNL), and L-gulono-1,4-lactone oxidase (GulLO). Eighteen putative GNLs were identified in Arabidopsis, one of which, AtGNL, is interesting because it possesses a chloroplastic signal peptide. Knockouts on this gene had lower foliar AsA and stunted growth compared to controls. The functional gene restored the phenotype of the knockouts, and those plants had higher AsA content, enhanced photosynthetic capacity, and higher seed yield.Type: GrantFiled: December 1, 2017Date of Patent: September 21, 2021Assignee: Arkansas State University—JonesboroInventors: Argelia Lorence, Jessica Patricia Yactayo-Chang

Patent number: 10704052Abstract: The process and system led to the identification of prenyltransferase genes from elicitor-treated peanut hairy roots. One of the prenyltransferases, AhR4DT-1 catalyzes a key reaction involved in the biosynthesis of prenylated stilbenoids, in which resveratrol is prenylated at its C-4 position to form arachidin-2, while another, AhR3?DT-1, was able to add the prenyl group to C-3? of resveratrol. Each of these prenyltransferases has a high specificity for stilbenoid substrates, and their subcellular location in the plastid was confirmed by fluorescence microscopy. Structure analysis of the prenylated stilbenoids suggest that these two prenyltransferase activities represent the first committed steps in the biosynthesis of a large number of prenylated stilbenoids and their derivatives in peanut.Type: GrantFiled: June 16, 2017Date of Patent: July 7, 2020Assignees: Arkansas State University—Jonesboro, Indiana University Research and Technology CorporationInventors: Luis Fabricio Medina-Bolivar, Tianhong Yang, Keithanne Mockaitis

Patent number: 10318672Abstract: The system effectively manipulates the operation of a charged particle flow device by approximating the total force on each ion during a trajectory calculation. The system applies the method in massively parallel general-purpose computing with GPU (GPGPU) to test its performance in simulations with thousands to over a million ions. The method calculates the forces on an ion using ions within an active region near the ion of interest. To decrease computation time, the method approximates the forces by calculating the ion-ion interactions within a first zone and the ion-ion cloud interactions within a second zone. The system adjusts settings of the charged particle flow device to affect the flow and positioning of the charged particles. Such setting may include adjusting the positioning of the charged plates, adjusting the voltage of the plates, and adjusting the pressure within the charged particle flow device.Type: GrantFiled: February 2, 2017Date of Patent: June 11, 2019Assignee: Arkansas State University—JonesboroInventors: Hideya Koizumi, Kenichiro Saito

Patent number: 10279366Abstract: The nozzle clog detection device, system, and method detect if a liquid flows through a nozzle via conduction of electricity. The clog detector provides an open circuit at an opening between two conductors. The two conductors are placed in the flow path of a liquid flowing from a nozzle. The liquid from the nozzle conducts electricity. The liquid flowing through the opening between the conductors closes the circuit. An alert system notifies the user whether liquid is flowing through the nozzle. The system detects flow of liquid from multiple nozzles and identifies the nozzles from which liquid flows. A break in the circuit at the opening between the conductors indicates that the liquid is not flowing sufficiently enough to close the circuit.Type: GrantFiled: March 2, 2018Date of Patent: May 7, 2019Assignee: Arkansas State University—JonesboroInventors: Peter Ako Larbi, Chin Nee Vong
