Diospyros mabacea Diospyros mabacea Diospyros mabacea, the red-fruited ebony is a rare rainforest tree in the ebony or persimmon family growing in north eastern New South Wales. Listed as endangered by extinction. Found at only thirteen sites in sub tropical rainforest near Murwillumbah and Mullumbimby (28° S), growing at low altutide. The original habitat is mostly destroyed by land clearing and housing. The current populations are threatened by invasive plants, particularly vines. Cattle trample over seedlings in private property. Not recorded in the nearby Gold Coast, however, it is possible that it once grew there before the extensive urban development in the
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
