Abstract
Provided herein are plants having enhanced lignification of root exodermis and methods of generating such plants.
Claims12
A method of generating a plant having enhanced lignification of root exodermis, the method comprising (a) genetically modifying a gene encoding a SlEXO zinc finger transcription factor to reduce or knockout expression of the SlEXO transcription factor;
- and (b) genetically modifying a gene encoding a heat shock transcription factor B4 Scz transcription factor to reduce or knockout expression of the Scz transcription factor;
- wherein the plant has enhanced lignification of root exodermis compared to a counterpart control plant.
The method of any one of the preceding claims, wherein the polypeptide encoded by the gene encoding SlEXO has at least 75% identity to SEQ ID NO:1 and/or the polypeptide encoded by the Scz gene has at least 75% identity to SEQ ID NO:3.s
The method of any one of the preceding claims, wherein the plant is a solanaceous plant.
A plant having increased having increased drought and/or salt tolerance, compared to a counterpart control plant, wherein the plant (a) is mutated or engineered to reduce or knockout expression of a gene encoding a SlEXO zinc finger transcription factor and (b) mutated or engineered to reduce or knockout expression of a gene encoding a heat shock transcription factor B4 Scz transcription factor.
