Increasing plant growth and yield by using a phenylalanine ammonia lyase sequence

Abstract

Compositions and methods for improving plant growth are provided herein. Polynucleotides encoding phenylalanine ammonia lyase (PAL) proteins, polypeptides encompassing PAL proteins, and expression constructs for expressing genes of interest whose expression may improve agronomic properties including but not limited to crop yield, biotic and abiotic stress tolerance, and early vigor, plants comprising the polynucleotides, polypeptides, and expression constructs, and methods of producing transgenic plants are also provided.

Description

field of invention [0001] The present invention relates to compositions and methods for increasing plant growth and yield by expressing a phenylalanine deaminase gene in a plant. Background technique [0002] The ever-increasing world population and dwindling supply of agriculturally arable land drive the development of plants with increased biomass and yield. Conventional crop and horticultural improvements employ selective breeding techniques to identify plants with desired traits. However, such selective breeding techniques have several drawbacks, namely, that these techniques are generally laborious and produce plants that often contain heterologous genetic elements, which may not always result in the desired trait being passed down from the parental plants. Advances in molecular biology have provided means to regulate plant germplasm. Genetic engineering of plants requires the isolation and manipulation of genetic material (typically in the form of DNA or RNA) and the...
