The present disclosure provides novel endophyte strains or cultures thereof that have a symbiotic relationship with plants. The present disclosure further provides methods of improving seed vitality, biotic and abiotic stress resistance, plant health and yield under both stressed and unstressed environmental conditions, comprising inoculating a seed with the novel endophyte strains and cultivating a plant therefrom.

1. A plant seed manually or mechanically coated with at least one endophyte, wherein the plant is not wheat and the endophyte is selected from the group consisting of a Streptomyces sp. strain or culture thereof which is deposited under IDAC 081111-06 or which comprises the 16S rDNA sequence as show
1. A plant seed manually or mechanically coated with at least one endophyte, wherein the plant is not wheat and the endophyte is selected from the group consisting of a Streptomyces sp. strain or culture thereof which is deposited under IDAC 081111-06 or which comprises the 16S rDNA sequence as shown in SEQ ID NO:6; a Paraconiothyrium sp. strain or culture thereof which is deposited as IDAC 081111-03 or which comprises the ITS rDNA sequence as shown in SEQ ID NO:5; a Pseudeurotium sp. or culture thereof which is deposited under IDAC 081111-02 or which comprises the ITS rDNA sequence as shown in SEQ ID NO:4; a Penicillium sp. or culture thereof which is deposited under IDAC 081111-01 or which comprises the ITS rDNA sequence as shown in SEQ ID NO:3; a Cladosporium sp. or culture thereof which is deposited under IDAC 200312-06 or which comprises the ITS rDNA sequence as shown in SEQ ID NO:1; and a Cladosporium sp. or culture thereof which is deposited under IDAC 200312-05 or which comprises the ITS rDNA sequence as shown in SEQ ID NO:2. 2. The coated plant seed of claim 1, wherein the plant is a cereal, pulse, flax or canola plant. 3. A method of improving seed vitality, plant health and/or yield comprising cultivating the coated plant seed of claim 1 into a first generation plant. 4. The method of claim 3, wherein the improving seed vitality, plant health, and/or yield is for increasing seed germination, for decreasing time to reach the energy of germination, for reducing hydrothermal time required for germination, for increasing seed germination vigour, for increasing the fresh weight of seedlings, for enhancing Rhizobium nodulation traits, for increasing yield of seedlings, for reducing the effects of stress on the seed or cultivated plant, for reducing the effects of drought, heat and/or biotic stress on the seed or cultivated plant, for reducing a Fusarium infection on the seed or cultivated plant, for enhancing stratification, for breaking dormancy, for reducing the effects of stress by modulating gene expression of hormonal ent-kaurenoic (KAO), for repression of shoot growth (RSG), abscisic acid (ABA), gibberellic acid (GA), 14-3-3 genes and nitric oxide (NO) molecules, and/or for modulating gene expression of stress resistance superoxide dismutase (SOD), manganese SOD (MnSOD), proline (Pro) or MYB genes. 5. The method of claim 3, wherein the plant is a cereal, pulse, flax, or canola plant. 6. A method of improving plant health and/or yield comprising manually or mechanically coating a plant seed with at least one endophyte, wherein the plant is not wheat and the endophyte selected from the group consisting of a Streptomyces sp. strain or culture thereof which is deposited under IDAC 081111-06 or which comprises the 16S rDNA sequence as shown in SEQ ID NO:6; a Paraconiothyrium sp. strain or culture thereof which is deposited as IDAC 081111-03 or which comprises the ITS rDNA sequence as shown in SEQ ID NO:5; a Pseudeurotium sp. or culture thereof which is deposited under IDAC 081111-02 or which comprises the ITS rDNA sequence as shown in SEQ ID NO:4; a Penicillium sp. or culture thereof which is deposited under IDAC 081111-01 or which comprises the ITS rDNA sequence as shown in SEQ ID NO:3; a Cladosporium sp. or culture thereof which is deposited under IDAC 200312-06 or which comprises the ITS rDNA sequence as shown in SEQ ID NO:1; and a Cladosporium sp. or culture thereof which is deposited under IDAC 200312-05 or which comprises the ITS rDNA sequence as shown in SEQ ID NO:2; and cultivating the coated plant seed into a first generation plant. 7. The method of claim 6, wherein the improving plant health and/or yield is for reducing the effects of stress. 8. The method of claim 6, wherein the improving plant health and/or yield is for reducing the effects of stress wherein the stress is heat, drought or biotic stress. 9. A method of phytoremediation or phytoreclamation of a contaminated site comprising cultivating the coated plant seed of claim 1 on the site into a first generation plant; thereby remediating or reclaiming the site. 10. The method of claim 9, wherein the site is contaminated with an organic chemical, a salt or a metal. 11. The method of claim 9, wherein the site is contaminated with an organic chemical and the organic chemical is a hydrocarbon or a petroleum. 12. The method of claim 9, wherein the site is contaminated with metal and the metal is lead or cadmium and/or a radioisotope. 13. The plant seed manually or mechanically coated with at least one endophyte of claim 1, wherein the endophyte is the Streptomyces sp. strain or culture thereof which is deposited under IDAC 081111-06 or which comprises the 16S rDNA sequence as shown in SEQ ID NO:6. 14. The plant seed manually or mechanically coated with at least one endophyte of claim 1, wherein the endophyte is the Paraconiothyrium sp. strain or culture thereof which is deposited as IDAC 081111-03 which comprises the 16S rDNA sequence as shown in SEQ ID NO:5. 15. The plant seed manually or mechanically coated with at least one endophyte of claim 1, wherein the endophyte is the Pseudeurotium sp. or culture thereof which is deposited under IDAC 081111-02 which comprises the 16S rDNA sequence as shown in SEQ ID NO:4. 16. The plant seed manually or mechanically coated with at least one endophyte of claim 1, wherein the endophyte is the Penicillium sp. or culture thereof which is deposited under IDAC 081111-01 which comprises the 16S rDNA sequence as shown in SEQ ID NO:3. 17. The plant seed manually or mechanically coated with at least one endophyte of claim 1, wherein the endophyte is the Cladosporium sp. or culture thereof which is deposited under IDAC 200312-06 which comprises the 16S rDNA sequence as shown in SEQ ID NO:1. 18. The plant seed manually or mechanically coated with at least one endophyte of claim 1, wherein the endophyte is the Cladosporium sp. or culture thereof which is deposited under IDAC 200312-05 or which comprises the ITS rDNA sequence as shown in SEQ ID NO:2.
