Outline of Final Research Achievements

The long-term selection, domestication, modified wild ancestor plants development to modern crops. As the results, artificial selection reduced such as seed dispersal, life cycle, time to maturation, but also increased in seed or fruit size and number and so on. The burden of population growth and additional farming for use in biofuels require increase in food production. Moreover, better shelf-life ensure less losses during processes of food producing, transporting, retailing, and serving.
The role of ethylene in fruit ripening has been reviewed as fleshy fruits of climacteric (tomato, apples, and banana) show a burst of respiration at the one set of ripening along with a large rise in ethylene production .Tomato fruit has been used as a model to study ripening. My research was focusing on one of the most important transcription factor, which regulate ethylene biosynthesis through control expression of ACS and ACO genes at the transcriptional level.
