W8405-1R: A Red Skin White Flesh Potato for the Fresh Market

UW–Madison researchers have developed W8405-1R, a red potato variety with very smooth and uniform tubers, round-oval shape, shallow eyes and attractive coloring that maintains well in storage.

The new variety is available through the Wisconsin Crop Improvement Association.

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.

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.
  • Cranberry Creek Cranberries Inc.
  • Dempze Cranberry Co.

Natural Antimicrobial Agent Derived from Biomass

UW–Madison researchers have identified an antimicrobial agent produced as a byproduct of biomass processing. The agent is a diferulate compound called poacic acid (and sometimes also called ‘8-5-DC’). It has been shown to target and destroy the cell walls of several species of fungus and yeast.

Gene Controls Flowering Time in Corn

The researchers now have found a gene in maize that affects flowering time. By modulating this gene, GRMZM2G171650, the onset of flowering in maize may be delayed or accelerated. Standard vector and transgenic methods can be employed to overexpress or suppress the gene, or introduce it into new crop lines.

The gene was identified by studying more than 500 different maize lines. The researchers mapped single nucleotide polymorphisms (SNPs) correlating to early or late flowering traits. A large concentration of such SNPs was located in GRMZM2G171650, a transcription factor on chromosome 3. The gene was of previously unknown function in corn.

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.
