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 cold and drought tolerance in transgenic "Arabidopsis thaliana" plants, was inserted into the tomato. This resulted in increased drought tolerance, but did not appear to have any effect on cold tolerance. Overexpressing a vacuolar Na/H antiport ("AtNHX1") from "A. thaliana" lead to salt accumulating in the leaves of the plants, but not in the fruit and allowed them to grow more in salt solutions than wildtype plants. They were the first salt-tolerant, edible plants ever created. Tobacco osmotic genes overexpressed in tomatoes produced plants that held a higher water content than wildtype plants increasing tolerance to drought and salt stress.
