Porcine viral diarrhea is an acute and highly contagious enteric disease of pigs that causes huge economic losses worldwide. Porcine epidemic diarrhea virus (PEDV) and transmissible gastroenteritis virus (TGEV) are the main pathogens responsible for piglet viral diarrhea. However, currently there is no specific drug available for the effective treatment of viral diarrhea. Therefore, it is necessary to seek an effective method to diminish PEDV and TGEV infection rates. RNA interference has been applied successfully to inhibit the virus replication. It provides a potential strategy for breeding resistant pigs. In this study, four promoters and four short hairpin RNA (shRNA) vectors with LoxP sites at each end of the selectable marker genes were constructed to target PEDV and TGEV. These vectors were then transfected into porcine fetal fibroblasts, G418 resistant transfectants were confirmed by PCR and transgenic SCNT porcine blastocysts were obtained. These results have paved the way for future production of marker-free transgenic resistant to PEDV and TEGV pigs by SCNT.

With the changes of climate and cultivation systems, the head blight (FHB) epidemic area in China has extended since 2000 from the reaches of the Yangtze River to the north and west winter wheat region. Breeding for FHB resistance in wheat is an effective way to control the disease. Chinese wheat breeders commenced research on FHB in the 1950s. Sumai 3, Ning 7840, Yangmai 158, Ningmai 9 and other cultivars with improved FHB resistance were developed through standard breeding methods and widely applied in production or breeding programs. In addition to intervarietal crosses, alien germplasm was used to improve FHB resistance of wheat. Addition, substitution and translocation lines with alien chromosomes or chromosome fragments were created to enhance FHB resistance. Somaclonal variation was also used to develop a FHB resistant cv. Shengxuan 3 and other cultivars with moderate resistance to FHB were released by such methods. QTL (quantitative trait loci) for FHB resistance were characterized in cultivars originating from China. The major QTL, , was identified on chromosome 3BS in Sumai 3, Ning 894037, Wangshuibai and other Chinese resistant sources. Diagnostic molecular markers for 1 have been applied in wheat breeding and breeding lines with improved FHB resistance and desirable agronomic traits have been obtained. However, breeding for FHB resistance is a long-term task, new technologies are likely to increase the efficiency of this process and better FHB resistance of new cultivars is expected to be achieved within the next decade.

Races belonging to the Ug99 (TTKSK) lineage of the wheat stem rust fungus, carrying complex virulence combinations, and their migration to countries in Africa, Middle East and Asia continue to pose a significant threat to global wheat production. The rapid spread of additional races, e.g., TKTTF or the Digalu lineage, in several countries causing localized epidemics reminds us of the vulnerability of wheat germplasm to stem rust disease, a formidable foe referenced as early as biblical times. A global rust monitoring system reflecting increased surveillance efforts has identified 13 races within the Ug99 lineage in 13 countries and unrelated lineages are emerging, spreading and posing serious threats to wheat production. Race TKTTF has caused localized epidemics in Ethiopia and its variants have been recently implicated in stem rust outbreaks in Europe. Concerted research efforts have resulted in the identification of several new resistance (APR) genes and gene combinations for use in breeding. Combining multiple adult plant resistance genes in high-yielding backgrounds and discovery of new quantitative trait loci conferring stem rust resistance has progressed in the recent years, enhancing the durability of resistance. Effective gene stewardship and new generation breeding materials and cultivars that combine multiple race-specific or minor to intermediate effect APR genes, complemented by active surveillance and monitoring, have helped to limit major epidemics and increase grain yield potential in key target environments.

大豆胞囊线虫(SCN,Heterodera glycines)是危害全球大豆生产最严重的线虫。作物轮作和培育抗线虫品种是防治线虫的主要方法。随着越来越多能够克服常用抗源的毒性SCN 群体出现,有必要寻找更多新的抗源或拓宽抗性遗传背景。本文综述了大豆抗SCN 基因的研究进展,以及这些基因如何相互作用,从而使大豆能够抗SCN。本文还提供了最新分子作图和分子标记,可用于不同抗性品系和品种的大规模选择和鉴定,以加速常规育种计划。深入了解SCN 寄生蛋白和大豆对病原体的抗性是通过基因修饰、基因叠加、回交或基因工程引入新的抗源而使抗源多样化的关键。

Phosphorus is the second most important macronutrient after nitrogen and it has many vital functions in the life of plants. Most soils have a low available P content, which has become a key limiting factor for increasing crop production. Also, low P use efficiency (PUE) of crops in conjunction with excessive application of P fertilizers has resulted in serious environmental problems. Thus, dissecting the genetic architecture of crop PUE, mining related quantitative trait loci (QTL) and using molecular breeding methods to improve high PUE germplasm are of great significance and serve as an efficient approach for the development of sustainable agriculture. In this review, molecular and phenotypic characteristics of maize inbred lines with high PUE, related QTL and genes as well as low-P responses are summarized. Based on this, a breeding strategy applying genomic selection as the core, and integrating the existing genetic information and molecular breeding techniques is proposed for breeding high PUE maize inbred lines and hybrids.
