Maize PR1 polynucleotides and methods of use

摘要

The present invention provides compositions and methods for enhancing the disease resistance of plants. The compositions are novel nucleic acid molecules isolated from maize, which encode pathogenesis-related (PR1) proteins, and the PR1 proteins encoded thereby. The methods comprise introducing into a plant cell at least one nucleotide construct comprising a PR1 nucleotide sequence of the invention operably linked to a promoter that drives expression in a plant cell. The methods additionally involve regenerating a stably transformed plant from the transformed plant cell. Transformed plants and seeds having enhanced disease resistance are also provided.
