Abstract

The present invention relates to a plasmid pUPI126 encoding indole-3 acetic acid (IAA) production, Acinetobacter strains having plasmid pUPI126, a bioinoculum for promoting growth of wheat plant, and a method of promoting wheat plant growth, the method comprising treating wheat seeds with the bioinoculum.

Claims

1. The plasmid pUPI126.

2. A Acinetobacter strain comprising the plasmid pUPI126.

3. The Acinetobacter strain of claim 2, wherein the strain is Acinetobacter haemolyticus strain MTCC 5218.

4. A bioinoculum for wheat plant, said bioinoculum comprising one or more Acinetobacter strains according to claim 2;

and a carrier.

5. A bioinoculum as claimed in claim 4 wherein the carrier is lignite.

6. A method of promoting wheat plant growth, said method comprising treating wheat seeds with the bioinoculum according to claim 4.

7. The method as claimed in claim 6, wherein the bioinoculum comprises the Acinetobacter haemolyticus strain MTCC 5218.

8. The method as claimed in claim 4 wherein the carrier in the bioinoculum is lignite.

9. The method as claimed in claim 4 wherein the Acinetobacter strain colonizes the wheat seeds during treatment.

10. The method as claimed in claim 4 wherein the color of the leaf of the wheat plant becomes darker green.

11. The method as claimed in claim 4 wherein the inflorescence and fruiting stages of the wheat plant is reached in a time duration lessened by 10 days.
