TL;DR: In this article, the application of the ANGPTL5 gene as a bovine backfat thickness molecular marker and a detection method was disclosed, which is applicable to molecular breeding of beef cattle; in initial stage of cattle breeding, the functional SNPs are used as markers for molecular breeding and assisted selection for modifying backfat-thinness traits of Chinese Simmental cattle; therefore, with the cost reduced, beef quality was further improved, breeding speed of fine varieties, and population quality was improved.
Abstract: The invention discloses application of ANGPTL5 gene as a bovine backfat thickness molecular marker and a detection method. After bovine genome-wide DNA is subjected to PCR (polymerase chain reaction) amplification, SNPs (single nucleotide polymorphisms) present in a PCR product sequence are detected through direct sequencing; it is discovered that four SNPs on an intron 1 and an intron 2 in the ANGPTL5 gene sequence are associated with bovine backfat thickness traits. A genetic marker in tight relation with bovine backfat thickness traits is screened and detected effectively, quickly and simply at DNA level; the genetic marker is applicable to molecular breeding of beef cattle; in initial stage of cattle breeding, the functional SNPs are used as markers for molecular breeding and assisted selection for modifying backfat thickness traits of Chinese Simmental cattle; bovine backfat thickness can be assessed and predicted quickly; therefore, with the cost reduced, beef quality is further improved, breeding speed of fine varieties is increased, and population quality is improved.

TL;DR: Progress on the genetic mapping and gene cloning of cyst nematode resistance in soybean and prospects are reviewed to discuss problems and prospects.
Abstract: Soybean cyst nematode (SCN), Heterodera glycines, is a serious and destructive pest in soybean production worldwide and causes great yield loss every year. Planting resistant soybean cultivars has been an economical and effective method to decrease or avoid its damage. Studying the molecular genetics of the resistance to SCN is the basis for molecular breeding. Here, we review progress on the genetic mapping and gene cloning of cyst nematode resistance in soybean and discuss problems and prospects.

TL;DR: In this article, the authors summarized recent advances in NGS technologies that have contributed toward the progress in crop bio-fortification, which is the process of crafting nutritionally dense crops containing vitamins, minerals, and crucial macro-micronutrients through conventional plant breeding methods, agronomic practices, genetic engineering, and next-generation sequencing (NGS) technologies.
Abstract: The modern-day agriculture is feeding the global population but not providing adequate essential nutrients which are known as “Hidden Hunger.” Deficiency of essential nutrients in daily diet is the cause of extensive health problems in developing countries, biofortification is the process intended to improve the nutrition level in all crops. The improvement of crop cultivars with increased level of nutrients in their edible parts is necessary to cope with nutrient deficiencies. Biofortification is the process of crafting nutritionally dense crops containing vitamins, minerals, and crucial macro-micronutrients through conventional plant-breeding methods, agronomic practices, genetic engineering, and next-generation sequencing (NGS) technologies. Rapid advancements in omics-NGS technologies have contributed immensely to the improvement of crop plants. Here, we summarized recent advances in NGS technologies that have contributed toward the progress in crop biofortification. As the cost of sequencing has declined, breeders started employing cutting-edge NGS technologies to sequence large plant populations to identify the genetic basis of agriculturally important traits and to predict the breeding value of individuals. Modern molecular breeding techniques like genome-wide association study (GWAS) and genomic selection (GS) are increasing the efficiency of breeding to enhance the rate of nutritionally rich cultivars of food crops in the most cost-efficient way. The biofortification of crops opens a new arena to address the malnutrition challenge that the world is facing.
