“…Moreover, a previous study found similar low frequencies of shared AFLP genotypes between Yunnan (17%) and Gansu (32%) populations. Thus, some extent of isolation between these two populations was indicated (Liu et al 2011). However, high frequencies of shared genotypes were detected between Ningxia (46%) and Gansu populations (72%) (Liang et al 2013), demonstrating the existence of frequent genotypic exchange between the two provincial populations.…”

“…The results demonstrated the high possibility of recombination in Gansu population. Liu et al (2011) studied the population genetics of the pathogen among different populations in Yunnan (southwestern China) and Gansu Provinces using AFLP, and concluded that a recombination signature was detected in Gansu populations but not in Yunnan populations. Lu et al (2011) studied spatial genetic diversity and possible interregional dispersal of P. striiformis f. sp.…”

Wheat stripe rust, caused by Puccinia striiformis f. sp. tritici, is one of the most important fungal diseases of wheat in China. Xinjiang, Qinghai, and Gansu Provinces, located in the northwest of China, are the key regions for interregional epidemics of wheat stripe rust due to their geographic as well as crop-planting features, in relation to pathogen’s life cycle, reproduction, and population genetics. To study the population genetic structures of the pathogen in these areas, 217 isolates of P. striiformis f. sp. tritici were collected from different geographic locations at various elevations in the three provinces. The amplified fragment length polymorphism (AFLP) genotypes and virulence phenotypes were analyzed for Xinjiang, Qinghai, and Gansu populations. Frequent genotypic exchanges between Xinjiang and Qinghai and between Qinghai and Gansu populations were detected, demonstrating that the populations of Xinjiang and Gansu may not be completely isolated. Genotypic diversity in Gansu Province was much higher than that in Xinjiang or Qinghai Province. The Xinjiang population was genetically closer to the Qinghai population than to the Gansu population. The race dynamic patterns in Qinghai were consistent with those in Gansu but the similar component pattern of the race dynamics in Xinjiang appeared late, following those in Gansu and other interior epidemic regions of China. No significant correlation between the AFLP genetic distance and the virulence distance in the Xinjiang, Qinghai, and Gansu populations was determined. A possible recombination signature of the pathogen population was detected in Gansu population and some subpopulations in Qinghai but not in Xinjiang population.

“…AFLP markers have revealed a clonal population in Northwestern Europe , and no amplified fragment length polymorphisms were found among Australian and New Zealand isolates (Steele et al 2001). Liu et al (2011) found 41 AFLP genotypes among 140 isolates from Yunnan province, China, and 22 genotypes out of 40 isolates from Gansu province, China.…”

“…Amplified restriction fragment length polymorphism (AFLP) can reveal high levels of polymorphism and is considered a robust method to study genetic diversity of wheat yellow rust (Villar eal et al 2002;Becerra et al 2007;Liu et al 2011), to understand the evolution of pathotypes (Zheng et al 2001), and to trace back aerial dispersal of this pathogen to other geographical regions Enjalbert et al 2005). AFLP markers have revealed a clonal population in Northwestern Europe , and no amplified fragment length polymorphisms were found among Australian and New Zealand isolates (Steele et al 2001).…”
