METHOD FOR INDUCING MULTIPLE LAYERS OF CASPARIAN STRIPS IN PLANT ROOT

摘要

A method for inducing multiple layers of Casparian strips in a plant root. The method induces a Casparian strip in a plant root using a plant transcription factor SHORT-ROOT (SHR) or MYB36 in combination with plant-derived small peptides CIF1 and CIF2. The constitutive (using a 35S promoter) or inductive (using an estrogen-inducible expression system) expression of SHR or MYB36 enables a plurality of genes involved in Casparian strip synthesis to be induced in cortical cells and other essential tissue cells in plant roots.
