Maize proteinase inhibitor-like polynucleotides and defense-activated promoter, transformed plants, and methods of use

摘要

Methods and compositions for modulating development and defense response are provided. Nucleotide sequences encoding a maize proteinase inhibitor-like protein is provided. Nucleotide sequences comprising the proteinase inhibitor-like promoter are also provided. Methods of using the promoter to express nucleic acid sequences of interest are provided. The sequences can be used in expression cassettes for modulating development, developmental pathways, and the plant defense response. Plants, plant cells, tissues, and seed transformed with the proteinase inhibitor-like gene or its promoter are also provided.
