The present invention is in the field of plant breeding and disease resistance. More specifically, the invention includes a method for breeding corn plants containing one or more markers that are associated with resistance to fungi. The invention further includes germplasm and the use of germplasm containing at least one marker associated with resistance to southern rust (SR) infection for introgression into elite germplasm in a breeding program, thus producing novel SR resistant germplasm.

The present disclosure is in the field of plant breeding and disease resistance. The disclosure provides methods for breeding corn plants having downy mildew (DM) resistance using marker-assisted selection. The disclosure further provides corn germplasm resistant to DM. The disclosure also provides markers associated with DM resistance loci for introgressing these loci into elite germplasm in a breeding program, thus producing novel DM resistant germplasm.

The invention relates to methods and compositions for identifying and selecting maize plants with enhanced resistance to northern leaf blight. Maize plants generated by the methods of the invention are also a feature of the invention.

Molecular markers useful for identifying, selecting, and/or providing soybean plants displaying tolerance, improved tolerance, or susceptibility to iron deficiency, methods of their use, and compositions having one or more marker loci are provided. Methods comprise detecting at least one marker locus, detecting a haplotype, and/or detecting a marker profile. Methods may further comprise crossing a selected soybean plant with a second soybean plant. Isolated polynucleotides, primers, probes, kits, systems, as well as soybean plants, seeds, and parts thereof are also provided.

The present invention “A Molecular marker Nicotine Associated SNP 1 for identifying high or nicotine content of tobacco and its kit as well as use thereof” belongs to field of molecular biology technology. The molecular marker Nicotine Associated SNP 1 is a SNP Nitab4.5_0002539:95304 A/G at base No. 95304 of Genomic segment No. 0002539 in tobacco genome version of Nitab v4.5 Genome Scaffolds Edwards2017. The present invention can accurately identify and screen tobacco germplasm resources with high or low nicotine content, and the screened tobacco can be directly used for breeding new tobacco varieties without transgenic methods. At the same time, gene sequence where the SNP site is located can also significantly activate promoters of key enzyme genes in nicotine synthesis pathway.

The disclosure relates to a series of independent human-induced non-transgenic mutations found at one or more of the Lip1 genes of a plant; plants having these mutations in one or more of their Lip1 genes; and a method of creating and finding similar and/or additional mutations of Lip1 by screening pooled and/or individual plants. The plants disclosed herein exhibit decreased lipase activity without having the inclusion of foreign nucleic acids in their genomes. Additionally, products produced from the plants disclosed herein exhibit increased hydrolytic and oxidative stability and increased shelf life without having the inclusion of foreign nucleic acids in their genomes.

The present invention is in the field of plant breeding and aphid resistance. More specifically, the invention includes a method for breeding soybean plants containing quantitative trait loci that are associated with resistance to aphids, Aphis glycines. The invention further includes method for monitoring the introgression quantitative trait loci (QTL) conferring aphid resistance into elite germplasm in a breeding program.

The present invention relates to a method for identifying and selecting plants resistant to a fungal disease comprising the steps of; (a) extraction of nucleic acid from a plant; (b) analysis of extracted nucleic acid for the presence of markers associated with increased fungal resistance within a single chromosome interval; and (c) selection of the plants that have these markers.

Furthermore, the invention also relates to a method for introgression into plants of fungal disease resistance alleles comprising the steps of; (a) crossing parents of plants identified by the first embodiment method with other parents that do not have this resistance; (b) select progenies possessing markers associated with increased resistance to fungal disease using the method as defined in the first achievement; and (c) backcross in one or more cycles the selected progenies with the recurrent genitor to develop new progenies.

Some embodiments described herein are methods, systems, and kits using tetra-primer ARMS-PCR for identifying processed material and detecting adulterant in the material under a unified condition with high specificity and sensitivity. In some embodiments, the tetra-primer ARMS-PCR includes a pair of inner primers and a pair of outer primers, wherein one or both inner primers have a 5′ end random nucleic acid modification and/or a 3′ end phosphorothioate bond modification.
