Genetic Evaluation and Breeding Utilization of Rice eui-Germplasm

Yang Rencui

Strategic Study of CAE 2005, Volume 7, Issue 8, Pages 26-30

Abstract:

The eui gene of rice and the diversity of tall recessive germplasm of rice were newly identified. Male sterile lines with elongated uppermost internode, and their corresponding hybrids (-hybrids) possessing eui gene were developed and released. The goals and the target of -hybrid rice research and development are： to cut short dosage of GA3 used in hybrid rice seed production by 50%～90% with increasing seed yield and improving seed quality; to increase hybrid rice yield with decreasing N-fertilizer applied to rice.

The EUI1， EUI2 were isolated, and the diversity showing nucleotide deletion of euil and eui2 were also identified This will provide the materials to enhance the studies on following area： plant growth and development, GA melabolism, growth hormones and heterosis, molecular mechanism of mutation, as well as gene engineering.

Plant genetic engineering and genetically modified crop breeding: history and current status

Xingchun WANG,Shujun CHANG,Jie LU,Rupert FRAY,Don GRIERSON,Yuanhuai HAN

Frontiers of Agricultural Science and Engineering 2017, Volume 4, Issue 1, Pages 5-27 doi: 10.15302/J-FASE-2017131

Abstract: This review charts the major developments in the genetic manipulation of plant cells that have taken place since the first gene transfer experiments using Ti plasmids in 1983. Tremendous progress has been made in both our scientific understanding and technological capabilities since the first genetically modified (GM) crops were developed with single gene resistances to herbicides, insects, viruses, and the silencing of unde-sirable genes. Despite opposition in some parts of the world, the area planted with first generation GM crops has grown from 1.7 Mhm in 1996 to 179.7 Mhm hectares in 2015. The toolkit available for genetic modification has expanded greatly since 1996 and recently Nobel Laureates have called on Greenpeace to end their blanket opposition, and plant scientists have urged that consideration be given to the benefits of GM crops based on actual evidence. It is now possible to use GM to breed new crop cultivars resistant to a much wider range of pests and diseases, and to produce crops better able to adapt to climate change. The advent of new CRISPR-based technologies makes it possible to contemplate a much wider range of improvements based on transfer of new metabolic pathways and traits to improve nutritional quality, with a much greater degree of precision. Use of GM, sometimes in conjunction with other approaches, offers great opportunities for improving food quality, safety, and security in a changing world.

Mutagenesis and selective breeding of a high producing

Tian WANG, Shiru JIA, Zhilei TAN, Yujie DAI, Shuai SONG, Guoliang WANG

Frontiers of Chemical Science and Engineering 2012, Volume 6, Issue 2, Pages 179-183 doi: 10.1007/s11705-012-1273-6

Abstract: -Poly- -lysine ( -PL) is an -lysine linear homopolymer, which is produced by bacteria belonging to the family and by ergot fungi. However, the production of -PL by the wild bacteria strain is very low, which limits its utilization. In most bacteria including the genus, -lysine is a precursor of -PL and is biosynthesized by the -aspartate pathway. Aspartokinase (Ask) is the first key enzyme in this pathway and is subject to complex regulation such as the feedback inhibition by the end product amino acids. In addition, phosphoenolpyruvate carboxykinase is feedback-regulated by -aspartate. To reduce these feedback inhibitions and to improve -PL productivity, resistant mutants were produced using sulfaguanidine (SG) + glycine+ -lysine+ -3-hydroxynorvaline (AHV) as selective markers. Using the interaction between -PL and the charged dye in the solid culture medium, hundreds of colonies were simultaneously screened in a quick and effective manner. Finally, one -PL-producing strain, L9, was selected. The productivity of this strain during flask fermentation was 0.77 g/L, which was 15% higher than that of the original strain. Moreover, its fermentation performance and genetic characteristics were very stable.
