Blossom end rot plummets in Purdue-developed transgenic tomato
Date:5/21/2012

WEST LAFAYETTE, Ind. - The brown tissue that signals blossom end rot in tomatoes is a major problem for large producers and home gardeners, but a Purdue University researcher has unknowingly had the answer to significantly lowering occurrences of the disease sitting on a shelf for 20 years.

In the early 1990s, horticulture professor Avtar Handa developed a transgenic tomato with a thicker juice that yields 10 percent more tomato paste than parental, non-engineered tomatoes. He said large commercial producers were interested but weren't ready to bring a transgenic tomato on the market, especially with the regulatory approval process that was required. So the research findings were published and the seeds stored away.

About two years ago, researchers at the University of California-Davis asked Handa for seeds from this tomato line. They were particularly interested in Handa's observations about how the tomatoes stored calcium, as several fruit diseases are thought to be caused by calcium deficiency. In particular, blossom end rot results in dark, softened spots on the end of tomatoes.

"Calcium is difficult to move from the soil into the plant," Handa said. "It is a major problem in tomatoes and many other fruit crops."

Handa shared his seeds with Elizabeth Mitcham, a post-harvest pomologist, and Sergio Tonetto de Freitas, formerly a doctoral student and now a postdoctoral researcher, both at UC Davis. They found that Handa's tomato plants essentially allow more calcium to be free and mobile in tomato cells, significantly reducing the occurrence of blossom end rot. According to the findings, published in the early online version of The Plant Journal, about 80 percent of wild-type tomatoes will suffer from blossom end rot in conditions conducive to the disease. Under similar conditions, only 30 percent of Handa's transgenic tomatoes develop blossom end rot.
