US 2026/0150848 A1 · NITROGEN-FIXING PAENIBACILLUS MICROBES

Abstract

The disclosure relates to microorganisms of the genus Paenibacillus, for the improvement of phenotypes of plants, for example nitrogen availability for non-leguminous plants. Included are novel strains of the microorganisms, microbial consortia, and agricultural compositions comprising the same. Furthermore, the disclosure teaches methods of utilizing the described microorganisms, microbial consortia, and agricultural compositions comprising the same, in methods for imparting beneficial properties to target plant species. In particular aspects, the disclosure provides methods of increasing desirable plant traits in agronomically important species, for example nitrogen fixation, utilization, regulation, uptake, acquisition, tolerance, and/or processing in plants.

A method of modulating a trait of agronomic importance in a plant obtained or derived from a plant element, the method comprising:

(a) treating the plant element with a formulation comprising a microbe, exudate therefrom, or culture broth therefrom, or solution, or dry formulation, wherein the microbe comprises:
i. a glnR gene and at least one set of genes selected from the group consisting of:
1. vnf;
2. anf;
3. hesA, nifB, nifD, nifH, nifK, nifE, and nifN, and optionally orf1;
and
4. a P-II gene, and/or nifA, and/or nifF, and/or nifJ, and/or nifL, and/or nifS, and/or nifW;
ii. a polynucleotide sequence sharing at least 98% identity with at least 100 contiguous nucleotides of a sequence selected from the group consisting of:
SEQ ID NO:1-293;
wherein the microbe is capable of fixing nitrogen;
and
(b) placing the plant element in a growth medium under conditions suitable for growth;
wherein a plant obtained from the plant element of (b) displays a modulated trait of agronomic importance as compared to a plant obtained from a plant element not treated with the formulation of (a).
