Scientists have deciphered the code of the water lily genome, a key step in the mystery of "flowering plants quickly occupying the Earth."

Recently, the study, "The Water lily genome and the evolution of early flowering plants", conducted by Zhang Liangsheng, a professor at Fujian University of Agriculture and Forestry, was published online in the journal Nature.
the study yielded a high-quality genome of blue-star water lilies.
due to the unique evolutionary position of water lilies, the results of the genome and transcription group show the evolutionary characteristics and characteristics of early flowering plants, which is of great significance for revealing the origin and evolution of flowering plants.
also analyzed the water lily's flower organ development and flower color regulation gene, which is of great reference value to the application of horticultural plant molecular breeding, and a key step is a key step in solving the mystery of how flowering plants can quickly occupy the earth in 200 million years.
flowering plants, also known as quilt plants, are mainly divided into real twin leaves, single leaves, magnolias and early flowering plantgroups.
early flowering plants have no oil camphor, water lily and magnolia vines. As an early quilt plant group, the genome and biology of
water lily are key links in understanding the origin and rapid radiation of quilt plants, which have important evolutionary status and basic research value.
at the same time, water lily is a famous aquatic ornamental flower, has important economic and cultural value.
in the past 20 years, a large number of water lily varieties have been cultivated around the world through hybridization.
it is understood that in this study, researchers obtained a high-quality genome of blue star water lilies, which, through systematic development al-sized analysis, showed that they belonged to an early quilt plant group, thus determining the evolutionary location of the water lily.
they also found a genome doubling event in the ancestors of the water lily, which occurred about 100 million years ago and was a double of an ancient genome, through genomic and transcription allottination.
studies show that the multipleization of the water lily genome contributes to the origin and widespread distribution of water lilies.
water lilies have flowers and flowers, the team also studied the development of their flower organs through the genome ABCE model and the synthetic way of flower fragrance, revealing some of the evolutionary characteristics of early quilt plants.
researchers compared the transcription group of naturally mutated white petals with blue petals to find that two important genes are the key enzymes that encode the synthetic pathways of blue petals. Experts
said the results of the water lily genome have deepened people's understanding of multi-fold and is an important landmark work in the study of the evolution of sub-plants.
the new breakthrough made in this study, it plays an important role in promoting the basic research of species origin evolution in the field of ornamental horticulture in China, and also provides a reference for the analysis of complex genomes of other horticultural crops.
the first intelligent genome breeding platform in China settled in Chengyang Street on December 10, the first intelligent genome breeding platform in China was inaugurated in Qingdao International Agricultural Life Wisdom Valley successfully held.
Qingdao Agricultural University Party Committee member, Vice President Liu Chunxia, Qingdao Agricultural and Rural Bureau, City Agricultural Technology Center Director Cheng Xingmu, City Yang District Standing Committee, Organization Minister Liu Xu and other attended the ceremony, the event was presided over by Pan Mengzhao, Director of the Bureau of Agriculture and Rural Affairs of Chengyang District.
China's first intelligent genome breeding platform by Qingdao Double Green Source Ino Technology Co., Ltd. founder - Chief Scientist Dr. Zhou Fasong led the establishment.
the use of modern life science and technology, cultivate green seeds, build corn, soybeans, wheat, tomatoes and other precision genome breeding system, for domestic and foreign universities, research institutes to provide genetic identification screening, variety upgrading and improvement services, from the source of cultivation to control pesticides, fertilizer pollution, to achieve "the safety of the tip of the tongue."
ceremony was first introduced by the head of Qingdao Double Green Source Ino Technology Co., Ltd.
introduced the industry pain points in the agricultural industry, as well as the core products and advantages of research and development for pain points.
ceremony, as a plant breeding research and development workers, Dr. Zhou Fasong made a solemn commitment to protect the public's healthy food source.
also said that for the breeding industry, for the brand of agricultural services, is the double green source has always wanted to do things, and now in the Valley of Wisdom has been achieved.
will make unremitting efforts in the future to contribute wisdom and strength to the revitalization of Shandong's rural areas and the development of modern agriculture. Liu Xu, a member of the Standing Committee of the
City Yang District Committee and Minister of Organization, pointed out in his speech that in recent years, the government of the Chengyang District Committee attaches great importance to the work of talents, fully implements the development strategy of talent priority, and introduces a series of supporting policies such as "Golden 20".
set up overseas talent-inducing workstations in the United States, Japan, London and other places, bringing together global talents in the city.
actively respond to the call of Qingdao "village revitalization offensive", solidly promote the "double-trick double-lead" work, attract ingons of high-level agricultural talents at home and abroad.
the introduction of "intelligent genome breeding platform" led by Dr. Zhou Fasong is an important measure of the "double-trick double-lead" work in Chengyang District, which injects new impetus into the construction of high-quality development of intelligent agriculture. Cheng Xingmu, director of qingdao agricultural and rural bureau and municipal agricultural technology center,
, expressed full recognition of the construction of the intelligent genome breeding platform and placed high expectations.
also pointed out that the provincial and municipal governments are making great efforts to cultivate new technologies, new industries, new industries and new models of intelligent agriculture, and the introduction of intelligent genome breeding platform is an important measure to enhance the level of agricultural intelligence, but also a new breakthrough in the rural revitalization offensive.
later, Qingdao Agricultural University Party Committee member, Vice President Liu Chunxia, Qingdao Agricultural and Rural Bureau, City Agricultural Technology Center Director Cheng Xingmu, City Yang District Standing Committee, Organization Minister Liu Xu jointly for the "first intelligent genome breeding platform" unveiled.
immediately followed, Qingdao Shuanggreen Source Ino Technology Co., Ltd. and Shandong Denghai Seed Industry Co., Ltd. in corn gene testing, genome editing technology reached a cooperation intention, and signed a strategic cooperation agreement on the spot. At the end of the
event, the leaders and guests visited Qingdao Double Green Source Ino Technology Co., Ltd. "Breeding Platform" under the guidance of the staff, and expressed their appreciation for its construction achievements.
the "intelligent genome breeding platform" landed in Qingdao International Agricultural Life Wisdom Valley, will give full play to the platform effect, drive the optimization of agricultural industrial structure, promote the transformation of new and old kinetic energy, promote the high-quality development of intelligent agriculture in Chengyang District, and open a new era of "smart agriculture, gene breeding".
about genomes: genomes, Genome, generally defined as a single chromosome in a haploid cell for a single genome, or a whole base in a haploid cell.
but genome sequencing found that gene coding sequences make up only a small part of the entire genome sequence.
therefore, the genome should refer to all DNA molecules in haploid cells, including encoded and uncoded sequences.
more accurately, the nuclear genome is all the DNA molecules in the nucleus of a monoploid; the mitochondrial genome is all the DNA molecules contained in a mitochondria; and the chloroplast genome is all the DNA molecules contained in a chloroplast.
human genome is the common wealth of all mankind.
experts at home and abroad generally believe that for the first time in the molecular level, the genome sequence diagram provides a life "description" for mankind, which not only lays the foundation of human self-awareness, promotes the revolutionary progress of life and medical science, but also brings the gospel to the health of all mankind.
