Abstract
The present disclosure provides methods to genetically engineer plants by manipulating the expression of the PtrXB38 polypeptide to increase root development. Also provided are genetically engineer plants that can be obtained by the methods according to the present disclosure.
Claims35
A genetically modified plant, plant cell or plant tissue, comprising an exogenous nucleic acid which comprises a nucleotide sequence encoding a PtrXB38 polypeptide,
- wherein (i) the nucleotide sequence has at least 98% sequence identity to the nucleotide sequence shown in SEQ ID NO:
- 1, or (ii) the PtrXB38 polypeptide has at least 98% sequence identity to the amino acid sequence shown in SEQ ID NO:
- 2, and
- wherein the genetically modified plant, plant cell or plant tissue displays an enhanced expression of the PtrXB38 polypeptide and an increase in root development compared to a wild-type plant, plant cell, or plant tissue.
A method of increasing root development in a plant, plant cell or plant tissue, comprising introducing into the plant, plant cell or plant tissue, an exogenous nucleic acid sequence encoding a PtrXB38 polypeptide, thereby obtaining a genetically modified plant, plant cell or plant tissue,
- wherein (i) the nucleotide sequence has at least 98% sequence identity to the nucleotide sequence shown in SEQ ID NO:
- 1, or (ii) the PtrXB38 polypeptide has at least 98% sequence identity to the amino acid sequence shown in SEQ ID NO:
- 2, and
- wherein the genetically modified plant, plant cell or plant tissue displays an enhanced expression of the PtrXB38 polypeptide and an increase in root development compared to a wild-type plant, plant cell, or plant tissue.
A method of increasing flooding tolerance in a plant or plant tissue comprising enhancing expression of a PtrXB38 polypeptide in the plant, or plant tissue, wherein the PtrXB38 polypeptide has at least 98% sequence identity to the amino acid sequence shown in SEQ ID NO:
- 2, thereby increasing flooding tolerance in the plant or plant tissue.
