  • Patent number: 11737462
    Abstract: Compounds and methods are described herein that are effective to modulate plant response (e.g., plant susceptibility) to environmentally-induced stress. The compounds and methods described herein advantageously may be used to modulate environmental stress resistance in a wide variety of plants. Environmental stresses include, for example, high light intensity (UV exposure), temperature (e.g., high heat), high soil salinity, and low soil moisture (e.g., drought). As used herein, environmental stresses include any conditions that result in increased generation of reactive oxygen species (ROS) and accumulation of ROS in the plant cells. The compounds described herein that are effective to modulate resistance to the stress prevent, directly or indirectly, or increase phosphorylation of Tyr248 of the RACK1A protein.

  • Patent number: 11373734
    Abstract: The present invention provides a method for populating and searching a drug informatics database that includes receiving unprocessed data associated with a chemical compound from one or more data sources. The unprocessed data is parsed into a plurality of data objects based on a categorization associated with each of the data objects. Additional information, such as explanatory notes, is identified and associated with at least one of the data objects. The data objects are stored in entries within a data structure, where the data structure is searchable based on one or more of the data objects. A query for data associated with a chemical compound is received at a drug informatics database. The drug informatics database is then searched for data associated with the chemical compound and the search results are provided to a user.
