Persimmon in color. The calyx generally remains attached to the fruit after harvesting, but becomes easy to remove once the fruit is ripe. The ripe fruit has a high glucose content and is sweet in taste. Like the tomato, persimmons are not commonly considered to be berries, but morphologically the fruit is in fact a berry. While many species of "Diospyros" bear fruit inedible to humans or only occasionally gathered, the following are grown for their edible fruit: Asian or Japanese persimmon ("Diospyros kaki") is the commercially most important persimmon, and is native to Japan, China, Korea, Myanmar and Nepal.

Genetically modified tomato function of genes naturally present in tomatoes. Wild tomatoes are small, green and largely unappetizing, but after centuries of breeding there are now thousands of varieties grown worldwide. Agrobacterium-mediated genetic engineering techniques were developed in the late 1980s that could successfully transfer genetic material into the nuclear genome of tomatoes. Genetic material can also be inserted into a tomato cell's chloroplast and chromoplast plastomes using biolistics. Tomatoes were the first food crop with an edible fruit where this was possible. Tomatoes have been used as a model organism to study the fruit ripening of climacteric fruit. To understand the mechanisms
