The present invention provides an inbred corn line designated GAQ2027, methods for producing a corn plant by crossing plants of the inbred line GAQ2027 with plants of another corn plant. The invention further encompasses all parts of inbred corn line GAQ2027, including culturable cells. Additionally provided herein are methods for introducing transgenes into inbred corn line GAQ2027, and plants produced according to these methods.

The generation of a chimeric protein containing a first domain encoding either a pro-thionon or thionin, a second domain encoding D4E1 or pro-D4E1, and a third domain encoding a peptide linker located between the first domain and second domain is described. Either the first domain or the second domain is located at the amino terminal of the chimeric protein and the other domain (second domain or first domain, respectively) is located at the carboxyl terminal. The chimeric protein has antibacterial activity. Genetically altered plants and their progeny expressing a polynucleotide encoding the chimeric protein resist diseases caused by bacteria.

The present invention is in the field of soybean variety AR1210501 breeding and development. The present invention particularly relates to the soybean variety AR1210501 and its seed, cells, germplasm, plant parts, and progeny, and methods of using AR1210501 in a breeding program.

The present disclosure provides methods for regulating stomata in plants, improving drought tolerance, and increasing resistance to bacterial pathogens through overexpression of genes NHR1 or GCN4. Also provided are transgenic plants with improved drought tolerance and increased resistance to bacterial pathogens produced by such methods.

Provided herein is a non-Nicotiana transgenic plant comprising an exogenous polynucleotide encoding Nicotiana benthamiana Roq1 or a variant thereof. These plants have enhanced resistance to at least one species of Xanthomonas, Pseudomonas, Ralstonia, and/or another pathogen containing a homolog of XopQ whose recognition is mediated by Roq1.

Methods are provided for enhancing the resistance of plants to bacterial pathogens. The methods involve transforming a plant with a polynucleotide molecule comprising a plant promoter operably linked to a nucleotide sequence that encodes a plant receptor that binds specifically with bacterial elongation factor-Tu. Further provided are expression cassettes, transformed plants, seeds, and plant cells that are produced by such methods.

Compositions, systems and methods are provided for conferring disease resistance to plant pathogens that use proteases to target plant substrate proteins inside plant cells. Briefly, the compositions, systems and methods are based upon plant substrate proteins that are targeted by pathogen-specific proteases and that activate nucleotide binding site-leucine rich repeat (NB-LRR) disease resistance proteins when cleaved by the protease. These substrate proteins are modified such that the endogenous protease recognition sequence is replaced by a protease recognition sequence specific to a different pathogen protease (i.e., a heterologous protease recognition sequence). The modified plant substrate protein therefore can be used in connection with its corresponding NB-LRR protein to activate resistance in response to cleavage by the heterologous pathogen-specific protease. When activated by the plant pathogen-specific protease, the pair initiates host defense responses thereto, including programmed cell death.

The present invention teaches methods and compositions useful for treating, preventing, or curing pathogen infections of living plants. In particular, the present invention teaches methods of enhancing plant response to pathogen-associated molecular patterns. The methods and compositions described herein are effective at treating biotrophic pathogens, including Liberibacters.

The invention relates to methods and compositions for modifying naturally non-mycorrhizal plants to produce modified plants that can be colonized by a mycorrhizal fungus having increased nitrogen and phosphorus uptake, increased drought tolerance/resistance, increased resistance to fungal and/or bacterial pathogens, and/or increased growth rate, yield and/or biomass production of a naturally non-mycorrhizal plant. The invention further relates to plants, plant parts, and/or plant cells produced by the methods of the invention as well as harvested and processed products from the plants, plant parts, and/or plant cells.

A nucleic acid expression vector comprising a nucleic acid sequence encoding a dominant negative T3SS protein is disclosed. The nucleic acid expression vector further comprising a cis acting regulatory element capable of driving transcription of the nucleic acid sequence in a plant cell. Moreover, the dominant negative T3SS protein mediates assembly of a dysfunctional needle complex.
