Diospyros dichrophylla Diospyros dichrophylla Diospyros dichrophylla (Gand.) De Winter aka poison star-apple is a Southern African tree belonging to the ebony family of Ebenaceae and closely related to the Persimmon ("Diospyros kaki"). Some authors describe it as being poisonous, which is puzzling as generally ripe fruits from this genus are quite tasty and edible, though green fruits are rich in tannins. The genus of "Diospyros" includes some 700 species, many of which are ornamental and many which bear edible and often cultivated fruit. This species grows into a medium-sized tree of up to 15 m tall. It is multi-stemmed and forms a
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
