Abstract
A bacteria which stimulates root production, or an extract in which the bacteria had been growing, is contacted to a portion of a plant other than a root. The root stimulating bacteria (RSB) or the extract induces the formation of roots in the plant. The RSB is well suited for inducing rooting in difficult to root species such as conifers of the Pinus genus. The RSB, the extract, the medium in which the RSB grows, the method for use of the RSB or the extract to induce rooting, and the plants treated with the RSB or the extract comprise the current invention.
Claims34
An isolated bacteria which has its 16S rRNA transcribed from a nucleotide sequence which comprises the DNA sequence shown in Sequence ID No. 6, and which is capable of inducing adventitious root formation in plants without pathogenicity to the plants.
A method for inducing adventitious root formation in a plant selected from the group consisting of evergreens and deciduous trees, without pathogenicity to the plant which comprises contacting a part of the plant, other than a root, to a bacteria which is capable of inducing adventitious root formation in the plant without pathogenicity to the plant, which bacteria has its 16S rRNA transcribed from the DNA sequence shown in Sequence ID No. 6, or to a growth medium in which the bacteria was grown, and planting the plant in a suitable growth medium for the plant.
A method for inducing adventitious root formation in a plant, without pathogenicity to the plant which comprises contacting a part of the plant other than a root to a bacteria which is capable of inducing adventitious root formation in the plant without pathogenicity to the plant, which bacteria has its 16S rRNA transcribed from the DNA sequence shown in Sequence ID No. 6, or to a growth medium in which the bacteria was grown, and planting the plant in a suitable growth medium for the plant.
A root stimulating bacteria which is obtained by a method which comprises:
- growing a pine seedling explant in in vitro agar culture,
- identifying a contaminant colony around the base of a rooted explant on the agar surface, and
- isolating a bacteria colony from the contaminant,
- wherein the bacteria has its 16S rRNA transcribed from the DNA sequence shown in Sequence ID No. 6.
