The invention pertains to a method for synthesizing a product of interest by culturing a microalgal cell producing the product of interest in the dark in a culture medium comprising an organic acid as a fixed carbon source, wherein the microalgal cell is a facultative heterotroph. The product of interest can be a microalgal biomass, a pigment, terpene, recombinant molecule, biogas, or a precursor thereof. In an embodiment, the culture medium comprises urea as a primary source of nitrogen. In one embodiment, the microalgal cell belongs to the order Chlamydomonadales. A method of identifying and isolating a microalgal cell having a preferred characteristic that is suitable for synthesis of a product of interest is also provided, the method comprising identifying and isolating a non-mutagenized or recombinant microalgal cell from a microalgal culture using a fluorescence activated cell sorting technique and/or a phototaxic response.

The invention generally relates to methods of screening a sample for cannabinoids.

The present disclosure provides a method for screening, isolating and purifying analytes.

The present invention provides high-throughput methods capable of screening compounds for herbicidal activity or plant growth regulating activity and further allows for the prediction of the mode of action of herbicidal compounds or plant growth regulators. The methods provided herein also facilitate the identification of mutation/s responsible for resistance to herbicides in plants and the identification of the herbicide target. The methods further provide for the identification of mutation/s responsible for plant growth regulation and the identification of the plant growth regulator target.

The present invention refers to a method for controlling undesired vegetation at a plant cultivation site, the method comprising the steps of providing, at said site, a plant that comprises at least one nucleic acid comprising a nucleotide sequence encoding a wild-type or a mutated protoporphyrinogen oxidase (PPO) which is resistant or tolerant to a benzoxazinone-derivative herbicide by applying to said site an effective amount of said herbicide. The invention further refers to plants comprising wild-type or mutated PPO enzymes, and methods of obtaining such plants.

Disclosed are isothiocyanate (ITC)-detecting biosensors that utilize recombinant host cells containing an ITC responsive genetic element such as a saxA promoter, operably linked with a reporter element, such as a luxCDABE operon or ilux operon. Such biosensors can detect the presence of diverse ITCs in samples such as plant extracts, biofumigated soils and seed meal amended soils.

The invention relates to a novel method for diagnosing the sulfur nutrition state of a plant by measuring the content of certain mineral nutrients in the leaves.

Provided herein are compositions and methods useful for the analysis and authentication of polysaccharide-rich herbs, such as Dendrobium officinale, Radix Astragali, Radix Angelica Sinensis, and related herbal products.

The present invention provides an organelle transformant screening method. More specifically, the present invention provides an organelle transformant screening method utilizing inhibition of a lipid synthetic pathway.

The present disclosure relates to luterion, which is a mitochondrial-like micro-material, and separating and culturing methods for same and, more particularly, to a method for separating luterion by means of a filter having a pore of a particular size, luterion which is separated by means of the method thereof and has unique properties, and a culturing method for proliferation of the luterion.
