  • Patent number: 12297439
    Abstract: Systems and methods for producing a plurality of unique edits in a plant's T1 seed. In one example, a method comprises transforming at least one expression cassette into a plant cell or a plant tissue. The at least one expression cassette may comprise a nucleic acid that encodes a DNA modification enzyme; optionally, a nucleic acid that encodes at least one guide RNA (gRNA); and a floral mosaic (FMOS) regulatory sequence, wherein the FMOS regulatory sequence (i) mediates expression of the DNA modification enzyme in at least one of a floral primordia cell and a floral reproductive organ, and (ii) mediates a plurality of edits in the at least one of the floral primordia and the floral reproductive organ. The method may also include regenerating the plant cell or plant tissue into a T0 plant having a plurality of T1 seed, wherein the T1 seed contain a plurality of unique edits.

  • Patent number: 7863493
    Abstract: A process for preparing an organic hydroperoxide, which process comprises: (a) oxidizing an organic compound to obtain an organic reaction product containing organic hydroperoxide; (b) mixing at least part of the organic reaction product of step (a) with a basic aqueous solution to obtain a mixture of basic aqueous solution and the organic reaction product; (c) separating the mixture of step (b) to obtain a separated organic phase containing organic hydroperoxide, and a separated aqueous phase; (d) mixing at least part of the separated organic phase of step (c) with water to obtain a mixture of an aqueous phase and the organic phase; and (e) separating the mixture of step (d) to obtain a separated organic phase containing organic hydroperoxide, and a separated aqueous phase; in which process the separation to a separated organic phase and a separated aqueous phase in step (e) is carried out with the help of a coalescer containing glass fibers.

  • Publication number: 20040210069
    Abstract: The invention relates to a process for preparing organic hydroperoxides, which process involves (a) oxidizing an organic compound to obtain a reaction product containing organic hydroperoxide, (b) treating at least part of the organic hydroperoxide containing reaction product with a basic aqueous solution and separating hydrocarbonaceous phase containing organic hydroperoxide from basic aqueous phase, (c) washing with water at least part of the separated hydrocarbonaceous phase containing organic hydroperoxide and separating hydrocarbonaceous phase containing organic hydroperoxide from aqueous phase, and (d) optionally repeating step (c) one or more times, in which process solid particles are removed from the reaction product containing organic hydroperoxide and/or basic aqueous solution before use in step (b), preferably by filtering. The invention also relates to a process for preparing oxirane compounds in which such organic hydroperoxide is used.
