Abstract: A device is provided for supplying a fluid to a cut plant. The device includes a container comprising a base and a surrounding wall extending from the base to define an enclosed space or cavity for holding the fluid. The device also includes a connector coupled to the container. The device further includes a flexible tube coupled to the connector at a first end and having a jagged open end, wherein the connector enables a fluid communication between the container and the flexible tube. A system is provided that includes such a device, a holder for the cut plant, and a fastener to secure the flexible tube to the holder. The flexible tube extends into the holder to allow the fluid to flow from the container to the holder, such that a fluid level in the container is the same as a fluid level in the holder.

Abstract: Methods of determining the presence or amount of a target polynucleotide in a sample are provided. A sample that contains a target polynucleotide, a polynucleotide that may include nucleic acid analogs and that is complementary to a target nucleic acid sequence of the target polynucleotide, and a dye for which the rate of change in an optical property is different in the presence and absence of a target polynucleotide/polynucleotide hybrid are combined to produce a reaction mixture. The rate of change in an optical property of the dye in the reaction mixture is compared to a reference value characteristic of the rate of change in the optical property of the dye in a similar reaction mixture containing a known amount of a polynucleotide/polynucleotide hybrid to determine a relative rate of change in the optical property. The relative rate of change in the optical property of dye in the reaction mixture is correlated with the presence or amount of the specified target polynucleotide in the sample.

Abstract: The present invention relates to the methods for assaying an analyte comprising a nucleic acid analog binding substrate in a sample, comprising reacting a catalytic complex comprising a nucleic acid analog, a nucleic acid analog specific binding substrate and a light reactive dye with a light stimulus, and detecting the presence or absence or amount of a reaction product of the catalytic complex and light stimulus. The present invention also relates to a method of assaying a nucleic acid analyte in a sample using an analyte-specific reporter complex. The present invention also relates to a method of assaying an analyte in a sample using a reporter molecule.

Abstract: The present invention relates to methods for detecting the presence or amount of a target polynucleotide. A polynucleotide, target nucleic acid analog, and dye are combined to form a mixture. The optical property of the dye is observed after the mixture is exposed to a stimulating means. Optionally, after the stimulating means is employed, the mixture is compared to a reference value characteristic of the rate of change in the optical property of the dye in a similar mixture containing a known amount of a target polynucleotide/nucleic acid analog hybrid to determine a relative rate of change in the optical property. The change in a property of the mixture after exposure thereof to a stimulating means or the relative rate of change in the optical property of dye in the mixture is correlated with the presence or amount of the specified target polynucleotide in the sample.

Abstract: A method for identifying non-host nucleic acid sequence using sequence data. The method of identifying non-host nucleic acid can include sequencing a sample into sequences and associating the sequences with a host genome and then exclude any sequences that are associated with the host genome. The method can then associate the sequences with any known genomes and exclude any sequences that are associated with any known genome. The remaining sequences can be used as seed sequences to assemble a non-host nucleic acid.
