ISOLATED NUCLEIC ACID MOLECULES ENCODING PLANT TRANSCRIPTION FACTORS IN THE KNOX FAMILY

摘要

Polynucleotides, DNA constructs and methods are disclosed for the modification of size, architecture of aerial and/or non-aerial portions of a plant as well as modification of the structure and/or chemical composition of the xylem of a plant. Plants are transformed with a gene encoding an active transcription factor belonging to the KNOX family. The over-expression of this gene in the plant's vascular system leads to increased overall size and architecture both in the shoot and root systems of the transgenic plant.
