The Root of the Problem

A professor, a graduate student and a team of farmers and researchers are doing some digging to learn about root rot.“It’s all about survival,” said Amit Dhingra, an associate professor in the Department of Horticulture. Read more at the Daily Evergreen.

Fruit Ripening Compounds Discovered

Scientists at Washington State University have discovered ripening compounds that show promise for making pears ripen more ­predictably.

Pears are mature, but unripe and hard when they are harvested, and some varieties, such as d’Anjou, require a period of chilling in storage before they will ripen.Read more of the article by Geraldine Warner at Good Fruit Grower.

Of 130+ applicants, 25 undergraduates receive awards to pursue research

PULLMAN, Wash. – Twenty-five students from a record pool of applicants for Washington State University awards in undergraduate research, scholarship and creative activities will each receive $1,000 to support their work.

Zachary Reeves, a freshman in electrical engineering mentored by Amit Dhingra is among the award recipients. He will research custom algorithms to execute programs and analyze data in the genomics and biotechnology lab.

Pear Industry Ripe for Change

When Dr. Amit Dhingra joined Washington State University seven years ago as a plant genomicist, one thing immediately struck him about the tree fruit industry.

Apples were a 2-billion-dollar high-tech industry, and the cherry industry was also advancing quickly, propelled by new varieties and ­rootstocks.

“These industries are on the move,” he noticed. “But in pears, we had not seen much advance in the last 100 years. It’s an industry which requires more application of knowledge so we can bring in change and transition.” Read the rest of the article by Geraldine Warner at Good Fruit Grower.

WSU scientists make genomes available for research

PULLMAN, Wash. – Anyone who has bought a hard pear at the supermarket can probably attest to the fruit’s unpredictable ripening process. But that unpredictability, one of the many traits stored in the plant’s genetic code, could be a thing of the past now that Washington State University scientists have sequenced four new Rosaceae crop family genomes, including the Comice pear.

The Pear Revival Journey

Soon after arriving at WSU in 2006, I embarked on a journey with a passionate set of individuals to revive an industry that has remained in suspended animation since the early 1900s. An email from a pear farmer in Yakima urged me to apply for funding to do pear research. That was my first introduction to a segment of the Pacific Northwest fruit industry that, while long an underdog relative to apples, has long sought to reinvent itself for the 21st century marketplace. » More …

Encouraging the Next Generation of Scientists

Eighteen-year-old Sequoia Leuba was already a seasoned researcher when she came to work this summer in the lab of WSU horticultural genomicist Amit Dhingra. In ninth grade, while her peers were just starting to classify the unseen world of microbes, Leuba was conducting research at a University of Pittsburgh microbiology lab.
