Abstract: The present invention is directed to promoters that have particular utility in driving root-specific expression of heterologous genes that impart increased agronomic, horticultural and/or pesticidal characteristics to a given transgenic plant. The present invention is also drawn to DNA molecules comprising the promoters of the invention and transformed plant tissues containing DNA molecules comprising a promoter of the invention operably linked to a heterologous gene or genes, and seeds thereof.

Abstract: The GmLMM1 gene, which is involved in the regulation of PTI immune responses, Phytophthora resistance, bacterial blight of soybean disease, soybean halo disease, etc., is cloned in soybeans. The PTI immune response and pathogen resistance of plants can be negatively regulated via the GmLMM1 gene. By reducing the expression of GmLMM1, the PTI immune response of plants can be effectively enhanced, and the pathogen resistance of plants can be increased. Cloning and functional discovery of the GmLMM1 gene provide important foundations and theoretical support for research on the related mechanisms of soybean disease resistance and provide valuable genetic resources for advancing the research and application of plant defense systems. Additionally, cloning and functional delivery of the GmLMM1 gene allows for breeding new soybean varieties with high disease resistance.

Abstract: The disclosure relates to polynucleotides comprising an endocarp-specific promoter sequence from the peach peroxidase (POX) gene operably linked to a heterologous nucleotide sequence encoding a product of interest. The polynucleotides can be used to specifically alter endosperm gene expression in fruit. In a transgenic cell, the polynucleotides may block formation of phenylpropanoid pathway lignin-pathway precursors, formation of lignin monomers, and/or polymerization of lignin monomers.
