Diospyros ebenum Diospyros ebenum Diospyros ebenum, or Ceylon ebony, is a species of tree in the genus Diospyros and the family Ebenaceae. The tree produces valuable black wood. This middle-high evergreen tree grows very slowly up to tall. The leaves are entire-like and have a prolonged oval form, about long and wide. The fruit is not very big, approximately in diameter. It resembles small persimmon fruit. Sap wood is light yellowish gray. The wood core is glossy-black seldom with occasional light fibers. This wood with metallic gloss also has fine and smooth texture. The wood grains can be straight, a bit chaotically
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
