Abstract:

Soybean plays an essential role in China’s economy. China is currently the largest soybean consumer and importer in the world,and the number of imported soybeans is increasing year by year. Soybean cyst nematode disease is a significant disease threatening major soybean producing areas globally,causing more than one billion US dollars in economic losses worldwide every year. The control of this pathogen is challenging. The use of resistant varieties is the most economical and effective measures to control soybean cyst nematode disease. At present,with the excessive use of a single resistant variety,the races of soybean cyst nematode continue to evolve,leading to reduced resistance and threatening the safety of the soybean industry. With the development of modern biotechnology,many researchers have elucidated the resistances to soybean cyst nematode by means of genetics,transcriptomics,and protein function studies. This review,summarizes the resistance mechanism of known major resistant sites Rhg1and Rhg4 in soybean,as well as the relationship between vlicular transport,phytohormone pathway and the resistance to soybean cyst nematode,discusses the significance of related functional proteins for soybean resistance and possible issues in the future research direction,and prospects the further reaches in this field. This is conducive to fully exploring the potential resistance genes of soybeans,laying a theoretical foundation for the creation of new soybean germplasms resistant to soybean cyst nematode,and serving the safe development of China’s soybean industry.
