Extracellular compounds produced by fungi associated with Botryosphaeria dieback induce differential defence gene expression patterns and necrosis in Vitis vinifera cv. Chardonnay cells

Three major grapevine trunk diseases, esca, botryosphaeria dieback and eutypa dieback, pose important economic problems for vineyards worldwide, and currently, no efficient treatment is available to control these diseases. The different fungi associated with grapevine trunk diseases can be isolated in the necrotic wood, but not in the symptomatic leaves. Other factors seem to be responsible for the foliar symptoms and may represent the link between wood and foliar symptoms. One hypothesis is that the extracellular compounds produced by the fungi associated with grapevine trunk diseases are responsible for pathogenicity.In the present work, we used Vitis vinifera cv. Chardonnay cells to test the aggressiveness of total extracellular compounds produced by Diplodia seriata and Neofusicoccum parvum, two causal agents associated with botryosphaeria dieback. Additionally, the toxicity of purified mellein, a characteristic toxin present in the extracellular compounds of Botryosphaeriaceae, was assessed.Our results show that the total extracellular compounds produced by N. parvum induce more necrosis on Chardonnay calli and induce a different defence gene expression pattern than those of D. seriata. Mellein was produced by both fungi in amounts proportional to its aggressiveness. However, when purified mellein was added to the culture medium of calli, only a delayed necrosis and a lower-level expression of defence genes were observed. Extracellular compounds seem to be involved in the pathogenicity of the fungi associated with botryosphaeria dieback. However, the doses of mellein used in this study are 100 times higher than those found in the liquid fungal cultures: therefore, the possible function of this toxin is discussed.

Botryosphaeria dieback, esca and Eutypa dieback are three economic major grapevine trunk diseases that cause severe yield reduction in vineyards worldwide. The frequency of disease symptoms has increased considerably over the past decade, and no efficient treatment is currently available to control these diseases. The different fungi associated with grapevine trunk diseases mainly induce necrotic wood and characteristic foliar symptoms. In this context, fungi virulence factors and host invasion are not well understood. We hypothesise that extracellular proteins produced by Diplodia seriata and Neofusicoccum parvum, two causal agents associated with Botryosphaeria dieback, are virulence factors responsible for the pathogenicity. In our previous work, we demonstrated that the total extracellular compounds produced by N. parvum induced more necrosis on Chardonnay calli and triggered a different defence gene expression pattern than those produced by D. seriata. Furthermore, this aggressiveness was not clearly correlated with the production of mellein, a characteristic phytotoxin of Botryosphaeriaceae, in our in vitro calli model. To characterise other potential virulence factors and to understand the mechanisms of host invasion by the fungus, we evaluated the profile, quantity and the impact of extracellular proteins produced by these fungi on Vitis vinifera calli necrosis and defence gene expression. Our results reveal that, under the same conditions, N. parvum produces more extracellular proteins and in higher concentrations than D. seriata. With Vitis vinifera cv. Chardonnay cells, we showed that equivalent concentrations of proteins secreted by N. parvum were more aggressive than those of D. seriata in producing necrosis and that they clearly induced more grapevine defence genes.

“…The symptoms caused by Botryosphaeriaceae on grapevines are significantly different between countries and vary depending on the cultivars. The most serious symptom reported in Chinese grapevines are 'cluster and fruit dropping' which differs to the major symptoms described in other countries (Yan et al 2013).…”

“…Presently 25 Botryosphaeriaceae species are known from grapevine worldwide (Úrbez-Torres 2011; Linaldeddu et al 2014; Dissanayake et al, First report of Neofusicoccum mangiferae associated with grapevine dieback in China (unpublished)). Morphological and multi-gene phylogenetic analyses confirmed Botryosphaeria dothidea, Diplodia seriata, Lasiodiplodia theobromae and Neofusicoccum parvum were associated with different grapevine dieback symptoms in Chinese vineyards (Yan et al 2013). Lasiodiplodia pseudotheobromae is reported for the first time on grapevine in Brazil as a grapevine trunk pathogen (Correia et al 2013).…”

A botryosphaeriaceous taxon causing fruit peduncle and pedicel discolouration was found infecting grapevines in Hubei and Jiangsu Provinces in China. Morphological and phylogenetic analyses showed the taxon to be Lasiodiplodia pseudotheobromae. Pathogenicity testing and Koch's postulates proved that Lasiodiplodia pseudotheobromae caused fruit peduncle and pedicel discolouration on grape fruit clusters. This is the first report of this fungus causing grapevine fruit peduncle and pedicel discolouration worldwide.
