Diospyros kaki in China, Japan and Korea. In East Asia the main harvest time for "kaki" is in the months of October and November. The trees lose their leaves by harvest time. Occasionally, the brightly colored fruit is left unharvested on the tree as a decorative effect. In China, "kaki" has been cultivated since time immemorial. It is considered to have four virtues: Cultivation of this species at first spread through East Asia. Since the 19th century, "kaki" partially replaced date-plum ("Diospyros lotus", also known as Caucasian persimmon) in some countries in South Europe and West Asia, because "kaki" have bigger fruits
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.
