The present disclosure provides a method for selecting a plant comprising a functional restorer gene for maize S-type cytoplasmic male sterility comprising the steps of (a) screening a population of plants for at least one marker nucleic acid, wherein the marker nucleic acid comprises an allele linked to the functional restorer gene for maize S-type cytoplasmic male sterility; (b) detecting the marker nucleic acid; (c) identifying a plant comprising the marker nucleic acid; and (d) selecting the plant comprising the marker nucleic acid, wherein the plant comprising the marker nucleic acid further comprises the functional restorer gene for maize S-type cytoplasmic male sterility. The present disclosure also provides methods for restoring fertility in a progeny of an S-type cytoplasmic male sterile plant and methods for transferring an Rf3 gene into a progeny plant.

The present disclosure relates to the field of plant breeding and, more specifically, to the development of white rust (Albugo occidentalis) resistant and downy mildew (Peronospora farinosa f. sp. spinaceae) resistant spinach plants having elite agronomic traits. The resistance to white rust is conferred by one or more alleles that co-segregate with at least one molecular marker selected from the group of SEQ ID No. 1-10. The resistance to downy mildew is conferred by an allele that co-segregates with at least one molecular marker selected from the group of SEQ ID No. 11-13. The disclosure relates further to the use of the molecular markers.

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.

A method of altering or transferring the cytotype of a plant line. In particular, transferring the cytotype of a transformation-recalcitrant plant line, e.g., a transformation-recalcitrant maize line, from a transformation-recalcitrant cytotype to a transformable cytotype so that the line becomes transformable while preserving its nuclear genome. The newly-transformable line may be produced using methods including backcrossing and/or haploid induction.

A method of enhancing grain yield of a Gramineae plant is provided. The method comprises: (a) crossing a recipient plant with a donor plant comprising a sequence variation in a TPR allele, said sequence variation imparting enhanced grain yield; and (b) selecting a progeny plant of said crossing comprising said sequence variation by identifying said variation, said progeny plant being characterized by an improved grain yield relative to said recipient plant. Also provided are plants and processed products resultant of the method.

The present disclosure is in the field of plant breeding. The disclosure provides methods for breeding corn plants having a brachytic trait using marker-assisted selection. The disclosure further provides brachytic germplasm, markers associated with a brachytic trait for introgressing the trait into elite germplasm in a breeding program. This disclosure also provides brachytic or dwarf elite corn varieties having yield equal to or higher than conventional non-brachytic corn varieties.

The present disclosure provides Brassica oleracea plants having curds or heads exhibiting increased resistance to downy mildew. Such plants may comprise novel introgressed genomic regions associated with disease resistance from Brassica oleracea MYCOCLP. In certain aspects, compositions, including novel polymorphic markers and methods for producing, breeding, identifying, and selecting plants or germplasm with a disease resistance phenotype are provided.

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 Fusarium stalk rot (FSR) infection for introgression into elite germplasm in a breeding program, thus producing novel FSR resistant germplasm.

The present invention relates to plants from the genus Alstroemeria L. with a new flower type. Specifically, the invention thus relates to an Alstroemeria L. plant, which may comprise a single flower per stem, which flower may comprise more than 6 tepals. This new trait is called herein “double-type flower”.

Disclosed are rice environmental conditional-lethal mutant gene osesl1, an encoding protein and use thereof The gene osesl1 has a nucleotide sequence shown as SEQ ID NO: 1 in the Sequence Listing. The encoding protein thereof has an amino acid sequence shown as SEQ ID NO: 2. After heading of osesl1 mutant rice, seed embryo lethal phenotype appears at 12 days after pollination, exhibiting darkening at the junction between embryo and endosperm. When an average temperature is below 22° C., a seed embryo is normal; when the average temperature is above 28° C., the seed embryo is lethal; when the temperature is between 22° C. and 28° C., the seed embryo is lethal under long daylight conditions (>13 h) and normal under short daylight conditions (<13 h). Use of the gene osesl1 in controlling seed embryo development of rice is further provided.
