Persimmon Persimmon The persimmon (sometimes spelled persimon) is the edible fruit of a number of species of trees in the genus "Diospyros". The most widely cultivated of these is the Asian or Japanese persimmon, "Diospyros kaki". "Diospyros" is in the family Ebenaceae, and a number of non-persimmon species of the genus are grown for ebony timber. The word "Diospyros" comes from the ancient Greek words "dios" ("δῐος") and "pyron" ("πῡρον"). A popular etymology construed this as "divine fruit", or as meaning "wheat of Zeus" or "God's pear" and "Jove's fire". The dio-, as shown by the short vowel 'i' has nothing
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.
