Soybeans with Increased Resistance to Sclerotinia Stem Rot and Drought Tolerance

UW–Madison researchers have demonstrated that knocking down expression of a specific soybean respiratory burst oxidase homolog protein (GmRBOH-VI) leads to enhanced resistance to S. sclerotiorum and confers drought tolerance.

Using protein sequence similarity searches, the researchers identified seventeen GmRBOHs and studied their contribution to Sclerotinia disease development, drought tolerance and nodulation. Transcript analysis of all seventeen GmRBOHs revealed that out of the six identified groups, group VI (GmRBOH-VI) was specifically and drastically induced following S. sclerotiorum challenge. Virus-induced gene silencing of GMRBOH-VI resulted in enhanced resistance to the fungus and, coincidently, drought stress.

Based on these discoveries, the researchers have developed modified soybeans and production methods available for licensing.

Genetic Testing for Acquired Peripheral Neuropathy in Dogs

UW–Madison researchers have identified a single nucleotide polymorphism (SNP) that is predictive of APN syndrome in dogs, based on a genome-wide association study. Using a population of Labrador retrievers (56 cases and 26 controls), the researchers have shown that a SNP on CFA1 tags the causal variant for APN in the Labrador retriever breed.

Noninvasive Assay for Bovine Embryo Quality

UW–Madison researchers have identified 11 microRNAs (miRNAs) and 18 mRNAs as indicators of healthy IVF embryo development. They discovered that the miRNAs are differentially expressed between bovine blastocyst-stage embryos and those that fail to develop (‘degenerates’). This is the first report that miRNA levels in the culture medium differ among embryos of different developmental fate and can be used as indicators of embryo viability.

Cranberry Variety Named “Ruby Star” with Consistent High Yield

A UW–Madison researcher has developed a new variety of cranberry known as “Ruby Star.” Ruby Star resulted from a cross between the “HyRed” cranberry (“Stevens” x “Ben Lear #8”) and the “Bergman” cranberry (“Early Black” x “Searles”).

Growers interested in this cranberry variety should license the variety from WARF and obtain vines from one of the approved propagators listed below. The license between WARF and the grower must be in place before vines can be obtained.

New Software Algorithm Advances Measurement Technology in Agribusiness

UW–Madison researchers have developed a new scanning algorithm for use in assessing yield and quality of crop production.

To determine characteristics such as kernel loading on an ear of corn and ear size, researchers scan up to three ears at a time using a common flatbed scanner. To measure 100 kernel weight, another common yield measurement, researchers weigh a handful of individual kernels and scatter them on the scanner. The resulting images are then analyzed using the algorithm to quickly provide yield data.

The algorithm uses a thresholding technique to separate the ears from the background and a Fourier transform to more accurately estimate kernel length. It also corrects for individual kernels clustering together.

Kit Predicts Twinning in Cattle

A UW–Madison researcher has developed a genetic test to determine the likelihood a cow or a bull’s female progeny will produce twin offspring. The test is based on the presence or absence of the ‘trio’ haplotype, which is a set of three genetic markers on bovine chromosome 10 (BTA10). In combination, these markers suggest a cow or bull has a higher propensity for twinning.

Optimizing Nitrogen Use Efficiency in Dairy Cattle

A UW–Madison researcher has developed a simple algorithm to optimize nitrogen use efficiency based on values already measured in most dairy herds: milk urea-nitrogen yield (MUNY) and protein yield (PY) in milk. Once an ideal MUNY/PY ratio is identified through careful measurement, the value can be constantly monitored to determine if feed practices need to be adjusted. This kind of feedback can be provided within a day, unlike any other method.
