  • Publication number: 20150114886
    Abstract: Seeds containing a genetic element of interest can be distinguished and sorted from a bulk sample of seeds. In certain embodiments, a marker is associated with at least some of the seeds containing a genetic element of interest, the seeds are excited using an photonic emitting device, and at least some of the seeds of the bulk sample are evaluated for the presence or absence of the marker and may be sorted based on the presence or absence of the marker. In certain embodiments, the marker is a red fluorescent protein marker. In certain embodiments, the red fluorescent protein marker is discernable when excited by a certain energy and the evaluating step comprises exciting the seeds containing a genetic element of interest with the certain energy and detecting an emission resulting at least in part from the exciting step.

  • Patent number: 7123750
    Abstract: The present invention relates to an apparatus, method, software algorithm and system for evaluating plants for conditions or characteristics. In one aspect, the method can include imaging at least a portion of the plant and evaluating the image for discriminating condition(s) or characteristic(s) of interest. In one example, soybean roots are imaged and the image is evaluated to discriminate between soybean cyst nematode (SCN) cysts and the plant roots to count the number of SCN cysts for the plant. In another embodiment, a plant is illuminated by a ultra-violet radiation selected to cause photo-induced fluorescence of a target, e.g. SCN cysts. The fluorescence emitted is collected and analyzed to discriminate between the target and the remainder of the plant.
