Genetic Diversity in Monilinia laxa Populations in Peach Orchards in Spain

Abstract: One-hundred and forty-four random amplified polymorphic DNA markers, of which 59 were polymorphic and 85 monomorphic, were used to assess the genetic diversity and to study the structure of Monilinia laxa populations in Spain. Twenty-one isolates collected from several orchards (subpopulations), in various years and in various hosts, were used. The analysis of population structure revealed that genetic diversity within orchards (H S ) accounted for 97% of the total genetic diversity (H T ), while genetic diver… Show more

“…It is worth observing the possible host specialisation during the genetic mapping and it is also worth studying of the genetic evolution of the populations. In the study, similarly to the one conducted by Gell et al (2007), no relationship was found in clustering among isolates according to the year of isolation or original host plant. According to this fact and the considerable variability within the populations revealed with MP-PCR, it might be concluded that there was no host specialisation in the investigated Monilinia population in Hungary.…”

“…Förster and Adaskaveg (2000) reported low degree of genetic diversity within M. laxa populations in Californian orchards. Gell et al (2007) conducted first European study to determine degree of genetic diversity in M. laxa within and among the orchards in Spain. It was concluded that the genetic diversity within subpopulations (orchards) was H S = 0.567, while genetic diversity between subpopulations was D ST = 0.018.…”

“…Most previous studies of the population structure of Monilinia spp. in stone fruit orchards (6,10,11,20,26,27) have utilized marker systems with low resolution (e.g., vegetative compatibility groups) or low reproducibility (e.g., RAPDs), hence there is a need to develop a new set of genetic markers for M. fructicola that are robust, have high resolution, and are codominant to potentially resolve heterokaryiotic isolates. Based on these considerations, a second objective of this study was to develop microsatellite markers for population genetics analysis in M. fructicola.…”
