“…Zealand and South Africa (Heath et al 2011). More recently, the abundance of N. parvum in some areas has been linked to environmental disturbance and host composition linked to human activity (Pavlic-Zupanc et al 2015). This could provide an explanation for the dominance of this pathogen from the samples obtained in this study.…”

Some species of the Botryosphaeriaceae are capable of infecting a broad range of host plants. We studied the species diversity of Botryosphaeriaceae associated with marula (Sclerocarya birrea subsp. caffra, Anacardiaceae) trees in South Africa over two seasons, as well as species common to both S. birrea and adjacent mango (Mangifera indica, Anacardiaceae) trees in a subset of sites. Gene flow amongst populations of Botryosphaeriaceae shared on these tree species was tested using microsatellite markers.Twelve species were identified from S. birrea and eleven species were found on M. indica trees. From isolations done in 2006, the dominant species on S. birrea was Neofusicoccum vitifusiforme, while N. parvum was the dominant species isolated from M. indica. Neofusicoccum parvum was dominant in isolations from both hosts in 2012. Isolates of Botryosphaeria fabicerciana, Lasiodiplodia mahajangana, L.pseudotheobromae, L. theobromae, N. mediterraneum and N. umdonicola were also collected from both hosts. Population genetic analyses on isolates of N. parvum suggested that three populations were present, each comprising isolates from both hosts. There was significant gene flow between N. parvum populations on these hosts. This ability to infect multiple hosts and to migrate amongst them facilitates the establishment and spread of species and genotypes of the Botryosphaeriaceae, such as N. parvum, in new areas.

“…In contrast, high levels of genetic diversity were detected in populations of N. parvum from various hosts in New Zealand, China, Colombia, Hawaii, Australia and South Africa. In these studies, high genetic diversity of N. parvum was explained by introductions of multiple genotypes over time and movement of this pathogen between native and non‐native hosts (Mehl, Slippers, Roux, & Wingfield, ; Pavlic‐Zupanc, Wingfield, Boissin, & Slippers, ; Sakalidis et al, ).…”

In the past decade, trees and shrubs in the Western Balkans region have been damaged by canker and die‐back disease caused by Botryosphaeriaceae species. These pathogens include Neofusicoccum parvum and Diplodia sapinea. In this study, we determine genetic diversity and structure between populations of N. parvum and D. sapinea from Serbia and Montenegro (Western Balkans) using DNA sequence data of the internal transcribed spacer rDNA, translation elongation factor 1‐alpha, β‐tubulin‐2 and microsatellite markers. The relationship of both pathogens was compared for populations from the Continental (CR) and Mediterranean (MR) regions and for isolates of D. sapinea from Cedrus spp. and Pinus spp. Neofusicoccum parvum and D. sapinea were shown to have a low gene and genotypic diversity across the regions and hosts. All genotypes of D. sapinea found on Pinus spp. were also present on Cedrus spp. The CR and MR populations of both species were found to be only slightly separated from one another by a geographical barrier. Low genetic diversity and dominance of N. parvum and D. sapinea on non‐native trees suggests that these species have most likely been introduced into Western Balkans, possibly through the movement of infected plants.

“…On Eucalyptus, it is commonly reported as a cause of canker and die-back (Nakabonge 2002;Ahumada 2003;Gezahgne et al 2004;Barber et al 2005;Mohali et al 2006;Rodas et al 2009;Chen et al 2011;Iturritxa et al 2011;Pillay et al 2013). In South Africa, Neofusicoccum parvum is also known from native Myrtaceae, including Heteropyxis natalensis and Syzygium cordatum (Smith et al 2001;Slippers et al 2004;Pavlic et al 2007, Pillay et al 2013, Pavlic-Zupanc et al 2015. Pavlic et al (2015) demonstrated that N. parvum is dominant and most abundant on S. cordatum in habitats influenced by human activity.…”
