Publication number: 20200196609Abstract: Methods and compositions are provided which employ a silencing element that, when ingested by a pest, such as a Coleopteran plant pest or a Diabarotica plant pest, decrease the expression of a target sequence in the pest. In specific embodiments, the decrease in expression of the target sequence controls the pest and thereby the methods and compositions are capable of limiting damage to a plant. The present invention provides various target polynucleotides set forth in any one of SEQ ID NOS: 1-236 or active variants and fragments thereof, wherein a decrease in expression of one or more the sequences in the target pest controls the pest (i.e., has insecticidal activity). Further provided are silencing elements which when ingested by the pest decrease the level of the target polypeptide and thereby control the pest. In specific embodiment, the pest is D. virgifera virgifera, D. barberi, D. speciosa, or D. undecimpunctata howardi.Type: ApplicationFiled: March 2, 2020Publication date: June 25, 2020Applicant: E. I.

Patent number: 10668711Abstract: The invention pertains to a photosensitive element, particularly a photopolymerizable printing form precursor; a method of preparing the photosensitive element to form a printing form for use in relief printing; and, a process of making the photosensitive element. The printing form precursor includes a layer of a photosensitive composition, a digital layer that is adjacent to a side of the photosensitive layer, and a cell pattern layer that is disposed between the photosensitive layer and the digital layer. The cell pattern layer includes a plurality of features, and is composed of an ink that is opaque to actinic radiation and transparent to infrared radiation. Since the cell pattern layer is integral with the printing form precursor, digital imaging can occur rapidly with relatively low resolution optics to form a mask without needing to also form a microcell pattern of the digital layer.Type: GrantFiled: May 26, 2016Date of Patent: June 2, 2020Assignee: E I DU PONT DE NEMOURS AND COMPANYInventors: Robert M Blomquist, Bradley K Taylor, John Stephen Locke, Mark A Hackler
