“…Climate is suggested as a limiting factor as different Botryosphaeriaceae species dominate the colonisation of grapevine in Mexico (Úrbez-Torres et al, 2008), Spain (Úrbez-Torres et al, 2006), South Australia and New South Wales (Pitt et al, 2010). Among the genera of Botryosphaeriaceae there does seem to be a general trend of Lasiodiplodia species being adapted to tropical to sub-tropical locations (Abdollahzadeh et al, 2010;Alves et al, 2008;Begoude et al, 2010;Burgess et al, 2006a;Pavlic et al, 2004) and Neofusicoccum species to Mediterranean and temperate locations Crous et al, 2007;Phillips et al, 2002;Slippers et al, 2004bSlippers et al, , 2004cTaylor et al, 2009;van Niekerk et al, 2004). Frequent anthropogenic movement could have had a major effect on speciation in this group.…”

“…On the mango fruit, (Ray et al 2010). Lasiodiplodia hormozganensis was recently described from M. indica and Olea sp in Iran (Abdollahzadeh et al 2010) and from non-native environments in Australia (originally identified as L. parva). Lasiodiplodia hormozganensis was isolated from A. digitata and a dying A. za in the NT and from a dying A. gregorii in Broome (Sakalidis et al 2011).…”

Pathogenic Botryosphaeriaceae associated with Mangifera indica in the Kimberley Region of Western Australia

Members of the Botryosphaeriaceae, in particular Lasiodiplodia theobromae, Neofusicoccum parvum, Neofusicoccum mangiferae and Botryosphaeria dothidea, commonly cause stem cankers, dieback and stem end rot of mangoes worldwide. In the current study, eight taxa of Botryosphaeriaceae were identified as canker-associated fungi, pathogens, potential pathogens or endophytes of mangoes in the Kimberley, Australia. These include Neoscytalidium novaehollandiae, Neoscytalidium dimidiatum, Pseudofusicoccum adansoniae, P. ardesiacum, P.kimberleyense, Lasiodiplodia sp. 1, Lasiodiplodia iraniensis and Lasiodiplodia pseudotheobromae. The pathogenicity of a selection of these species toward fruit and branches was tested. All were pathogenic to mango in comparison to the control, with Lasiodiplodia spp.being the most pathogenic. It appears that either geographic isolation or the unique growing conditions in the Kimberley may have provided an effective barrier to the acquisition or establishment of known botryosphaeriaceous pathogens. Wounds caused by mechanical pruning may provide an entry point for infection, whilst severe pruning may increase plant stress.

“…Many of the other fungi did not sporulate after extensive incubation under these conditions. To induce sporulation, isolates thought to belong to the family Botryosphaeriaceae were grown on pine needles, as described in the literature (Pavlic et al 2008;Abdollahzadeh et al 2010;Begoude et al 2010). A representative of each Botryosphaeriaceae morphospecies was subcultured on WA (water agar), then six segments of autoclaved pine needles were laid in parallel on a plate.…”

Mimosa pigra dieback in the Northern Territory, Australia: Investigation into possible causes

In this study, Mimosa pigra dieback is described as plants or population of plants which appeared to suffer from ill health, death of their growing points and the emergence of green reshoots coming from the base. Dieback is an important phenomenon, not only in many crops and natural forests worldwide, but also in many invasive trees and shrubs in Australia. The dieback phenomenon is thought to be caused by complex and interacting factors and causes are often difficult to disentangle. In some cases it is a result of an interaction between both biotic and abiotic factors. Since 1988, dieback has been widely observed in Mimosa pigra L.(Fabaceae), a woody shrub that is one of the most serious exotic invaders of floodplains and riparian areas in the Top End of the Northern Territory. However, there has been no conclusive evidence of links between M. pigra dieback and specific causal factors. In addition, the dieback phenomenon has not been previously quantified.This thesis aimed to describe M. pigra dieback phenomenon at plant and population levels and its effect on plant growth, survival and demography. Specifically, the aim of this thesis was to evaluate the role of biotic factors (insect borers and fungal pathogens), and abiotic factors (soil pH and salinity), in relation to the development of M. pigra dieback. In addition, the thesis examines the pathogenicity of the fungal endophytes/pathogens associated with diebackaffected and healthy M. pigra. M. pigra has been a focus of biological control programs for more than 30 years, but it still remains a serious threat in the wetlands and conservation areas in the Top End of the Northern Territory. While extensive studies have been conducted to evaluate the impact of biological control programs, little is actually known about dieback and its causal factors.To evaluate the causal factors of M. pigra dieback, repeated ground surveys, plant health assessment and specimen collection of stems and soils, were conducted in the period 2011 to 2013 in established M. pigra sites on Melaleuca Station, Mary River, Northern Territory. Insect borers were quantified and putative fungal pathogen abundance were surveyed. A combined morphological and phylogenetic approach was used for fungal pathogens/endophyte identification. Using a subset of isolates, trials were performed to examine differences in the pathogenicity of the recovered fungal pathogens/endophytes.Results of field research showed that dieback in M. pigra is highly dynamic and fluctuates in its severity. Different sites showed increases and/or decreases in plant health over time.iii Dieback affects plants in all age classes, from seedlings, juveniles to adult plants, resulting in partial mortality of plants in all age categories over the trial period. Contrary to expectations, none of the biotic and abiotic factors examined showed a direct relationship to the changing population dynamics of M. pigra dieback over time. Nevertheless, fungal isolations demonstrated that M. pigra is a host to a diverse range of endop...
