The present invention relates to an agronomic composition comprising zinc, manganese and microorganism(s) capable of promoting nutrient uptake by a plant from the soil. Furthermore, the present invention provides a seed coated by an agronomic composition according to the invention and a method for improving the yield of a plant, in particular for increasing nutrient uptake and/or cold tolerance in early stages of development by applying the agronomic composition according to the invention to a seed or to soil, in which a seed is planted. Finally, the present invention also relates to the use of an agronomic composition of the present invention to improve the yield of a plant. In particular, the composition of the present invention is used to improve recovery of a plant and/or to prevent tissue damage when the plant is exposed to low temperatures at the seed or seedling stage.

Methods for improving the ability of a population of biological agents to compete and survive in a field setting are provided. By improving the population of biological agents, the modified population of agents is able to grow, compete with other microbial strains and fungi, and provide protection for plants from pathogens. In particular, modified biological agents and modified populations of such agents that are herbicide tolerant or resistant are selected or engineered. In this manner, the protection from disease-causing agents is enhanced. Such modified populations of biological agents can be added to soils to prevent fungal pathogens and the diseases they cause promoting plant growth. Therefore, the present invention is useful for enhancing the competitiveness of modified biological agents particularly over other microbial agents which are not herbicide resistant. Compositions of the invention include selected or engineered herbicide resistant biological agents and modified populations of biocontrol agents. These modified biological agents can be used as an inoculant or as a seed coating for plants and seeds.

The inventive technology generally relates to novel plant endophytic bacterial strains that may colonize discrete plant tissues, and in particular the roots of a plant and may further be engineered to express and deliver interfering RNA molecules throughout the plant.

Compositions and methods are provided for use in controlling souring and corrosion causing prokaryotes, such as SRP, by treating oil and gas field environments or treatment fluids with a newly identified bacterial strain ATCC Accession No. PTA-124262 as a self-propagating whole cell that produces an anti-SRP bacteriocin in situ. In another aspect, the methods use one or more toxic peptides or proteins isolated therefrom in methods to control unwanted prokaryotic growth in these environments.
