Gene For Seedlessness Could Lead To Seedless Varieties Of The Tasty Cherimoya Fruit

March 14, 2011: 12:00 AM EST
Plant scientists in the U.S. and Spain have discovered a gene that could lead to creation of  seedless varieties of the tasty cherimoya, also known as the custard apple, a South American fruit that has many large seeds. The advance could make the fruit as popular as bananas, the researchers suggest. Spanish researchers studying the seedless variety of sugar apple consulted with an American scientist studying a mutant variety of the plant Arabidopsis that does not make seeds or fruit. Working together they found that the same gene was responsible for uncoated ovules in both the Arabidopsis and sugar apple mutants. This gene for seedlessness could lead to development of seedless varieties of sugar apple, cherimoya and perhaps other fruits.
