A large number of functional lncRNAs have been discovered with the increasing development of deep sequencing techniques and bioinformatics tools.This paper conducted a search on the NCBI PubMed and NCKI database to pick out from the research literature of the last 5 years the functional genes that regulate muscles,fat,reproduction and immunity.The paper provides a comprehensive review of the latest research progress on the regulatory effects of lncRNAs in transcriptomes of muscle,fat,reproduction and disease resistance,which are the key traits for enhancing the economic performance of the dairy and beef cattle industries.This review seeks to provide scientific findings and evidence for the molecular breeding of dairy and beef cattle with a view to improving the economic performance of the dairy and beef cattle industries.
ObjectiveTo improve the fertility purity of beet monogerm cytoplasmic male sterile lines and maintainers.MethodForty pairs of molecular markers from a collection of 620 monogerm cytoplasmic male sterile and maintainer sugar beet germplasms were identified.All genetically mixed markers in the sterile and maintainer plants were given specific codes and recorded.Subsequently, a morphological observation was carried out in the field to exclude genetically impure plants.Result The verification of heredity purity by molecular markers revealed 92 DNA including 73 in the maintainers mixed with that of the sterile plant and 19 in the sterile lines contaminated with that belonged to the maintainer.The field examination on pollens and grains identified 122 plants (as compared to 92 isolated by the molecular marker verification) with 73 maintainers and 49 sterile lines to be promiscuous.In addition, polygerm plants were unexpectedly found in the lot that could have grown from the accidentally included seeds.Conclusion By excluding adulterated plants in the field, the purity on heredity of sterile and maintainer lines could be assured.The procedure would provide the prerequisite essential for accurate genetic diversity determination and successful preparation of binary sterile sugar beet lines.
