Identification, distribution and current taxonomy of Botryosphaeriaceae species associated with grapevine decline in New South Wales and South Australia

Use of the Genealogical Sorting Index (GSI) to delineate species boundaries in the Neofusicoccum parvum–Neofusicoccum ribis species complex

“…rainfall, humidity and host stress. 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).…”

Class III endophytes, clandestine movement amongst hosts and habitats and their potential for disease; a focus on Neofusicoccum australe

“…Other reports of N. australe in WA have been from Eucalyptus plantations and grapevines (Taylor et al 2005). N. australe has been collected sporadically from hosts in eastern Australia; most reports were linked to ornamental or horticultural settings in Victoria (Slippers et al 2004;Cunnington et al 2007), Canberra (Slippers et al 2004), New South Wales (Slippers et al 2004;Pitt et al 2010) and South Australia (Pitt et al 2010), whilst N. australe has been collected from native hosts in only four instances, all from Acacia spp. (Slippers et al 2004).…”

“…Collections were made from V. corymbosum in Australia (Cunnington et al 2007) and Chile (Inderbitzin et al 2010;Espinoza et al 2009). Whilst, V. vinifera was recorded as a host of N. australe in Australia (Taylor et al 2005;Cunnington et al 2007;Pitt et al 2010 ). There are also reports of N. australe occurring on grapevines in Mexico; however, sequence data are not currently publically available for this (Candolfi-Arballo et al 2010).…”

“…Within Australia, N. australe has been collected from 22 host species encompassing Haplotypes 1, 4, 5, 6 and 13; all these haplotypes except for H4 were found in Western Australia: Acacia cochlearis, Acacia mearnsii, Acacia rostellifera, Acacia sp., Agonis flexuosa, Allocasuarina fraseriana, B. coccinea, B. grandis, C. preissii, E. holopetalus, E. diversicolor, E. globulus, E. gomphocephala, E. marginata, E. phylacis, Phoenix canariensis, Salix sp., Santulum acuminatum, Sequoiadendron giganteum, Vaccinium corymbosum, Vitis vinifera, and W. nobilis (Shearer et al 1995;Slippers et al 2004Slippers et al , 2005Cunnington et al 2007;Taylor et al 2009;Pitt et al 2010). …”

“…Symptoms include stem cankers, dieback, wedge shaped lesions in grapevine stems and fruit rot. N. australe has been associated with symptomatic grapevine in Western Australia (Taylor et al 2005), southern and eastern Australia (Cunnington et al 2007;Pitt et al 2010), New Zealand (Amponsah et al 2009, South Africa (van Niekerk et al 2004) and USA (California) (Úrbez-Torres et al 2006;Úrbez-Torres and Gubler 2009). Other fruit crop declines have linked N. australe to olive "drupe rot" in Italy (Lazzizera et al 2008) and dieback symptoms of peach, plum and apricots in South Africa (Damm et al 2007;).…”
