People often complain about grocery store tomatoes, saying they’re too hard and don’t have the flavor we remember from the days of old. And we thought we knew why - because the millions of tons of tomatoes harvested in the United States and beyond have to be picked before they’re fully ripe and juicy in order to survive being shipped long distances. What’s more, many shoppers store their tomatoes in the fridge, which destroys both their flavor and texture.
But guess what? It’s not just how tomatoes are grown, harvested and stored that affect their flavor. A research team led by Ann Powell, a biochemist in the UC Davis Department of Plant Sciences, has discovered a gene mutation that diminishes a...
You know how it works: You stand in the grocery aisle, surreptitiously sniffing the cantaloupes, hoping your nose will lead you to a nice, ripe selection. But when you slice it open in your kitchen, it’s just not as ripe as you had hoped. Lucky for you (and me), UC Davis Department of Plant Sciences Assistant Professor Florence Negre-Zakharov and her team may have found a way to make imperfectly ripe fruit a thing of the past.
"We are involved in a project geared towards developing rapid methods to evaluate ripeness and flavor of fruits," explained Negre-Zakharov, who authored a paper on the method published in the
While working in Tanzania on community development projects several years ago, Iago Lowe came to a life-changing conclusion:
Food security is central to projects that make a lasting difference in people's well-being. It ensures that communities have the seeds, soil, water and environment to produce enough to eat.
However, his bachelor's degree in physics and religion from Dartmouth College did not adequately prepare him to spearhead those kinds of projects.
To address that gap in his ability to "make some small difference in the world," Lowe started doctoral studies at UC Davis in 2007 in plant breeding and genetics.
"There are so many needs in developing nations — for schools, roads, water, other...
Here we are, a month into summer, and one of my favorite fruits is starting to emerge: Luscious tomatoes, fresh off the vine.
I know, most of us treat tomatoes like a vegetable in the kitchen, slicing and dicing them into dishes that are savory rather than sweet. Botanically speaking, tomato is a fruit because it’s developed from the ovary in the base of the flowers and contains the seeds of the plant (though cultivated forms may be seedless.)
No matter, the tomato is a nutritional powerhouse any way you cut it, loaded with vitamin C, vitamin A, potassium and lycopene, an antioxidant credited with preventing both cancer and heart disease.

I don’t know if plant scientists make better chefs, but knowledge of plant science can certainly improve our cooking. Take, for example, understanding how to handle oxidation, the interaction between oxygen molecules and all the many substances they may contact. Oxidation is what makes your fender rust and your copper penny turn green. As it relates to plants, oxidation is what causes fresh-cut produce to turn brown and wine to lose its flavor when left too long in an open bottle.
Perhaps you know how to thwart oxidation when preparing potatoes and serving sliced apples (and if not, we’ll get to that in a minute) but here is a less-common food that often falls victim to oxidation: pesto. Has this happened to you? You gather an...
