Scientists first published tomato genome

Business Club June 1 news tomato also known as tomato, persimmon, wolf peach, plums, kumquat This kind of vegetable, which was initially regarded as toxic, has been very common in our daily table, but scientists do not know much about the genetic mechanism of this plant Researchers from Cornell University, University of Nottingham, National Center for genetic research of Chinese Academy of Sciences and other places recently published the article "the tomato genome sequence provides insights into fleshy fruit evolution", which first published the genome of tomato (Solanum lycopersicum) The tomato variety sequenced was Heinz 1706 The results were published in nature This achievement has expanded the efforts of tomato genome association (TGC) over the years This International Association includes more than 300 scientists from 14 countries, including Argentina, Belgium, China, France, Germany, India, Israel, Italy, the United States and so on James Giovanni from Cornell University's Boyce Thompson Institute of Botany and the U.S Department of agriculture led the U.S tomato sequencing team, which consists of several research institutions, including the genome sequence of wild-type tomato (Solanum pimpinellifolium), which was completed by Cold Spring Harbor Laboratory According to the study, tomatoes have about 35000 genes and 12 chromosomes "We have captured almost all genes in essence about various characteristics of tomatoes, including taste, natural insect resistance, and nutrients." Said Giovanni Nature describes in detail the sequence of these genes and their distribution on chromosomes "Tomato genome sequence analysis is helpful for the evolution of succulent fruits." this information will also be used to cultivate people's favorite improved taste and more abundant nutrition, such as lycopene In addition, it can reduce costs, fight against pathogens, drought and plague On the other hand, genome sequences also provide important information And with the release of this tomato genome information, it will be easier and cheaper for seed companies and plant reformers to sequence the genome needed for other types of research and development, Giovanni said The cost of sequencing the first tomato genome has reached millions of dollars, and the subsequent sequencing may be reduced to less than 100000 dollars In order to facilitate researchers' access to gene sequences of tomatoes and related species, Lukas Mueller of Boyce Thompson Research Institute and his team created an interactive website: www.solgenomics.net In addition, Zhang Fei of Boyce Thompson Research Institute and Joyce van Eck also published their analysis data In addition, the UK part is responsible for chromosome 4 The team consists of scientists from the University of Nottingham and Imperial College London, as well as the center for genome analysis, James Hutton Institute, the University of East Anglia (UEA) and the Museum of natural history They have completed high-quality chromosome sequences that are considered standard worldwide This sequence analysis reveals the relative association of tomato genes, which will help to reveal the relationship between tomato genes and their displayed characteristics Tomato is one of the members of Solanaceae family, and its new sequence will also provide reference for identifying the relatives of Solanaceae family, such as potato, pepper, eggplant and Petunia In terms of economic value and yield, Solanaceae family is the most important family of vegetable crops in the world China and Dutch scientists have jointly launched the "100 tomato genome research program" Last May, BGI and ttigg jointly announced the launch of this program They hope to complete the sequencing and assembly of 100 tomato genomes in one year, and carry out information analysis and in-depth mining based on a large number of data obtained from sequencing to analyze the tomato genome sequence The results lay a solid foundation for the cultivation of new varieties with high yield, high quality, disease and insect resistance Chinese research institutions involved in this study include Beijing Academy of agricultural and Forestry Sciences, national genetic research center of Chinese Academy of Sciences, Shenzhen BGI, China Agricultural University, vegetable and Flower Research Institute of Chinese Academy of Agricultural Sciences, etc.
