Novel microsatellite markers suitable for genetic studies in Polyporus umbellatus (Polyporales, Basidiomycota)

About Ganoderma boninense in oil palm plantations of Sumatra and peninsular Malaysia: Ancient population expansion, extensive gene flow and large scale dispersion ability

“…Our results show a rather high genetic diversity across peninsular Malaysia and Sumatra, with a global H e value of 0.651 and a mean allele number of 9.27. In comparison, the white rot fungus Armillaria mellea, (order Agaricales) has a genetic diversity ranging between 0.103 and 0.600, depending on the population considered (Prospero et al 2008;Travadon et al 2012 b) and the Polyporus umbellatus (order Polyporales) has a genetic diversity of 0.544 (Liu et al 2015). The high genetic diversity observed in G. boninense, along with the small number of duplicated genotypes found in our sample, indicate that sexual reproduction plays a key role in spreading the disease, as proposed by Miller (1995), Pilotti et al (2003), and Rees et al (2012), Despite the fact that some palms could be infected by multiple genotypes (Miller 1995;Ariffin et al 1996;Pilotti et al 2003;Rees et al 2012) and that we only collected one fruiting body at random from each palm, the small number of duplicate genotypes we found (less than 2 %) suggests that disease spreading by root-toroot infection is anecdotal.…”

Development of novel polymorphic microsatellite markers in the invasive plant shortawn foxtail (Alopecurus aequalis Sobol.)

“…Twelve primer pairs were all polymorphic; Na ranged from 2 to 5 alleles with a mean of 4.08, while PIC values ranged from 0.345 to 0.750 with an average value of 0.604 (Table 1). According to the previous report (Liu et al , 2015), the loci polymorphic level can be considered high, medium, or low if PIC > 0.5, 0.5 > PIC > 0.25 and PIC < 0.25. In this study, all loci in the 20 natural populations had a high PIC value (Mean = 0.604), indicating the utility of using these SSR markers for future genetic research.…”
