Dr. Esther van der Knapp, Professor in the Department of Horticulture and the Center for Applied Genetic Technologies, Institute of Plant Breeding, Genetics & Genomics and her team of scientists from UGA and The Ohio State University have recent had their work on Cell size regulation published in PLOS genetics, a very prestigious genomic science journal. According to the research summary: “Starting about 10,000 years ago, during the Neolithic period, human societies began the transformation from a hunting and gathering-dependent lifestyle to an agrarian lifestyle. This transformation was accompanied by plant and animal domestication. Tomato shows a huge increase in fruit weight that has arisen as a consequence of its domestication. We identified a gene that encodes a poorly characterized protein that controls fruit weight in tomato. The mutation that led to the increase in fruit weight arose early during the cultivation of tomato and is now incorporated in all large tomato varieties. The gene regulates cell size in the fruit and is called Cell Size Regulator. The increases in cell size are proposed to relate to cellular maturation that accompanies fruit growth.”
