  • Patent number: 11363768
    Abstract: The present disclosure provides a method for selecting a plant comprising a functional restorer gene for maize S-type cytoplasmic male sterility comprising the steps of (a) screening a population of plants for at least one marker nucleic acid, wherein the marker nucleic acid comprises an allele linked to the functional restorer gene for maize S-type cytoplasmic male sterility; (b) detecting the marker nucleic acid; (c) identifying a plant comprising the marker nucleic acid; and (d) selecting the plant comprising the marker nucleic acid, wherein the plant comprising the marker nucleic acid further comprises the functional restorer gene for maize S-type cytoplasmic male sterility. The present disclosure also provides methods for restoring fertility in a progeny of an S-type cytoplasmic male sterile plant and methods for transferring an Rf3 gene into a progeny plant.

  • Publication number: 20220146414
    Abstract: Provided are methods and/or systems having advantages of cost effective, time saving, and informative user-friendly characteristics to accomplish trait introgression. The methods provided comprise determining presence of omega-3 fatty acids (for example docosahexanoic acid or DHA; docosapentaenoic acid or DPA; Alpha linolenic acid or ALA; and eicosapentaenoic acid or EPA) using Fourier Transformed Infra Red (FTIR) spectrum. The use of FTIR enables analysis of the oil contained in the seeds using a multivariate-based Mid-FTIR model. The methods and/or systems provided advantages of non-destructive analysis to provide information to facilitate trait introgression and other breeding applications.
