Diospyros pentamera Diospyros pentamera Diospyros pentamera is a common rainforest tree in the Ebony or Persimmon family (Ebenaceae) growing from near Batemans Bay (36° S) in New South Wales to the Atherton Tableland (17° S) in tropical Queensland, Australia. It is commonly known as the myrtle ebony, black myrtle, grey plum or grey persimmon. "Diospyros pentamera" is a small to large rainforest tree, from 6 to 40 metres in height at maturity, and 60 centimetres in width at the base. It grows in various types of rainforests, but grows best in volcanic soils in fire free areas with high rainfall. The leaves
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.
