Described herein are compounds, methods, and kits for long-term tracking of cell proliferation, differentiation, and/or function. The compounds of the present invention are novel cell-tracking reagents, efficiently excitable with a 405-nm violet laser, that provide bright fluorescence intensity, uniform cell staining, and good retention within cells as well as low toxicity toward cells.

This application relates to methods and materials for providing a benefit to a seed or seedling of an agricultural plant (e.g., an agricultural grass plant), or the agricultural plant derived from the seed or seedling. For example, this application provides purified bacterial populations that include novel seed-origin bacterial endophytes, and synthetic combinations of seeds and/or seedlings (e.g., cereal seeds and/or seedlings) with heterologous seed-derived bacterial endophytes.

The present invention provides a new species of tobamovirus and its use to identify plants comprising resistance against the virus.

The present disclosure provides compositions and methods for sensing a target substance of interest in the environment and inducing gene expression in response thereto, useful for detection of biological and chemical agents and environmental pollutants.

A method for disrupting a sample of biological material of human, animal, or plant origin for subsequent proteome analysis by a mass spectrometry method is provided. The method involves disrupting the sample by treatment with a certain volume of an organic acid until the sample completely dissolves, incubating the sample for a certain period, and then neutralizing the sample with a neutralizing solution until a pH value between 7 and 9 is reached.

This application relates to methods and materials for providing a benefit to a seed or seedling of an agricultural plant (e.g., an agricultural grass plant or a Glycine plant), or the agricultural plant derived from the seed or seedling. For example, this application provides purified bacterial populations that include novel seed bacterial endophytes, and synthetic combinations of seeds and/or seedlings (e.g., cereal or soy seeds and/or cereal or soy seedlings) with heterologous seed-derived bacterial endophytes.

Materials and methods for improving plant traits and for providing plant benefits are provided. In some embodiments, the materials, and methods employing the same, can comprise endophytes.

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.
