An expanded genetic linkage map of an intervarietal Agaricus bisporus var. bisporus×A. bisporus var. burnettii hybrid based on AFLP, SSR and CAPS markers sheds light on the recombination behaviour of the species

Constructing a new integrated genetic linkage map and mapping quantitative trait loci for vegetative mycelium growth rate in Lentinula edodes

“…This is similar to a value (20.7 %) reported previously (Terashima et al 2002). Several hypotheses have been proposed to explain distorted segregation, such as biased selection of SSIs, expression of lethal factors and unbalancing selection of mating-types (Larraya et al 2000;Foulongne-Oriol et al 2010). The mapped skewed loci appeared to locate together as segregation distortion regions in the genetic map, as previously reported in L. edodes (Terashima et al 2002), P. pulmonarius (Okuda et al 2009) and P. eryngii (Okuda et al 2012).…”

“…Genetic maps of several other edible mushrooms, including Agaricus bisporus (Kerrigan et al 1993;Callac et al 1997;Moquet et al 1999;Foulongne-Oriol et al 2010, Pleurotus ostreatus (Larraya et al 2000;Park et al 2006;Sivolapova et al 2012), Pleurotus pulmonarius (Okuda et al 2009) and Pleurotus eryngii (Okuda et al 2012), have been reported previously. For L. edodes, several molecular genetic maps are currently available.…”

“…Compared to previous studies (Table 5), the current study involved the largest mapping population (146 SSIs), which could ensure the accuracy of genetic mapping (Foulongne-Oriol et al 2010). Additionally, the present genetic map contained 13 LGs with 524 markers, and spanned 1006.1 cM, with an average marker distance of 2.0 cM.…”

“…where m is the total number of markers and G i is the length of LGi after adding 2s (Remington et al 1999;Foulongne-Oriol et al 2010). The marker distribution within each LG was tested by whether the observed genetic positions of the markers are under a uniform distribution or not, using the KolmogoroveSmirnov test (Foulongne-Oriol et al 2010).…”
