Disclosed herein is a UV mutagenesis produced new Streptomyces spororaveus strain SC263 that exhibits an increased thermostability of the antibiotic produced, which shows antibiotic activity against bacteria and fungi. Also provided are the antibiotic produced by SC263 and a composition thereof for treatment of bacterial and fungal infections. The antibiotic has a very high molecular weight, which is suitable for topical administration.

The present invention is directed to methods and compositions for increasing a growth characteristic of a plant, increasing nutrient use efficiency of a plant, or improving a plant's ability to overcome biotic or abiotic stress comprising applying a composition comprising a fungal mycelia extract comprising piperidine and/or an analogue thereof (e.g., 6-oxopiperidine-2-carboxylic acid) and/or a salt thereof (e.g., 6-oxopiperidine-2-carboxylate), or any combination thereof to a plant, plant part, or to a propagation material of the plant.

The invention provides materials and method for attracting and controlling plant-pathogenic nematodes. In specific embodiments, compositions are provided comprising Valerian root, which draws the nematodes away from plants, and/or a microbe-based composition comprising nematicidal microorganisms and/or their growth by-products, which control the nematodes upon contact. The compositions can be applied to a plants environment, including soil, to attract and control nematodes, and to reduce and/or prevent plant damage caused by nematodes.
