Diospyros mespiliformis Diospyros mespiliformis Diospyros mespiliformis, the jackalberry (also known as African ebony and by its Afrikaans name jakkalsbessie), is a large dioecious evergreen tree found mostly in the savannas of Africa. Jackals are fond of the fruit, hence the common names. It is a member of the family Ebenaceae, and is related to the true ebony ("D. ebenum") and edible persimmon ("D. kaki"). Mature trees have dark gray fissured bark. An adult tree reaches an average of 4 to 6 metres in height, though occasionally trees reach 25 metres. The foliage is dense and dark green with elliptical leaves, which are
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
