“…Botryosphaeriaceae fungi have been reported as endophytes, latent, opportunistic and primary pathogens in numerous fruits, forestry and ornamental woody plants worldwide (Batista et al, 2021;Slippers et al, 2013;Slippers & Wingfield, 2007). On olive trees, these fungi have been isolated from stem cankers, die-back, fruit rot or leaf lesions in the Mediterranean regions such as Greece (Phillips et al, 2005), Italy (Carlucci et al, 2013;Lazzizera et al, 2008), Spain (Moral et al, 2010(Moral et al, , 2019Romero et al, 2007) and Tunisia (Chattaoui et al, 2011(Chattaoui et al, , 2012 and also from other non-traditional olive regions such as New Zealand (Taylor et al, 2001), Australia (Sergeeva et al, 2009), United States (Moral et al, 2010;Úrbez-Torres et al, 2013), Croatia (Kaliterna et al, 2012), Montenegro (Latinovic et al, 2013), Turkey (Korukmez et al, 2020) and South Africa (Spies et al, 2020). Also, numerous species of this family have been found associated with olive, especially those belonging to the genus Neofusiccocum, but also from the genera Botryosphaeria, Diplodia, Dothiorella and Lasiodiplodia (Carlucci et al, 2013;Lazzizera et al, 2008;Moral et al, 2010Moral et al, , 2019Úrbez-Torres et al, 2013).…”

Olive production has expanded strongly in the last twenty years in Uruguay. In this study, a collection of 37 Botryosphaeriaceae isolates obtained from stem canker and fruit rot symptoms in olive trees of six cultivars from 14 orchards throughout the country were characterized. Based on phylogenetic analysis of ITS and TEF-1α gene regions and phenotypical characteristics, eight species belonging to the genera Botryosphaeria (41%), Neofusicoccum (51%) and less frequently to Diplodia (8%) were identified. The recognized species were B. wangensis (n = 11), N. cryptoaustrale (n = 9), N. luteum (n = 7), B. dothidea (n = 4), N. occulatum (n = 2), D. seriata (n = 2), N. australe (n = 1) and D. mutila (n = 1). Isolates of all Botryosphaeriaceae species were able to cause typical necrotic lesions on inoculated olive stems of Arbequina cultivar under laboratory conditions, but those belonging to Neofusicoccum genus were significantly more aggressive. Five of the eight species found in this study were previously reported affecting other fruit and forestry trees in Uruguay; thus, further epidemiologic studies and management programmes should be developed considering all the Botryosphaeriaceae hosts, especially those cultivated in proximity. Also, we present B. wangensis, N. cryptoaustale, N. occulatum and D. mutila species as new records to olive worldwide.

Efficacy of Dimethyl Trisulfide on the Suppression of Ring Rot Disease Caused by Botryosphaeria dothidea and Induction of Defense-Related Genes on Apple Fruits

Apple ring rot caused by Botryosphaeria dothidea is prevalent in main apple-producing areas in China, bringing substantial economic losses to the growers. In the present study, we demonstrated the inhibitory effect of dimethyl trisulfide (DT), one of the main activity components identified in Chinese leek (Allium tuberosum) volatile, on the apple ring rot on postharvest fruits. In in vitro experiment, 250 μL/L DT completely suppressed the mycelia growth of B. dothidea. In in vivo experiment, 15.63 μL/L DT showed 97% inhibition against the apple ring rot on postharvest fruit. In addition, the soluble sugar content, vitamin C content, and the soluble sugar/titratable acidity ratio of the DT-treated fruit were significantly higher than those of the control fruit. On this basis, we further explored the preliminary underlying mechanism. Microscopic observation revealed that DT seriously disrupted the normal morphology of B. dothidea. qRT-PCR determination showed the defense-related genes in DT-treated fruit were higher than those in the control fruit by 4.13–296.50 times, which showed that DT inhibited apple ring rot on postharvest fruit by suppressing the growth of B. dothidea, and inducing the defense-related genes in apple fruit. The findings of this study provided an efficient, safe, and environment-friendly alternative to control the apple ring rot on apple fruit.

“…However, apple cultivation is threatened by apple ring rot caused by Botryosphaeria dothidea , bringing about fruit rot, stem and branch canker, and even tree death. Moreover, B. dothidea also infects many other fruit trees, including avocado (Qiu et al, 2020 ), mulberry (Huang et al, 2019 ), pomegranate (Gu et al, 2020 ), fig (Wang et al, 2020 ), sweet cherry (Zhang et al, 2019 ), kiwifruit (Wang et al, 2021a ), and olive (Korukmez et al, 2019 ). The disease has become one of the most destructive diseases in China (Dong and Guo, 2020 ).…”

Apple ring rot caused by Botryosphaeria dothidea is an essential and prevalent disease in the apple orchard in China. Our previous study demonstrated that dimethyl trisulfide (DT) from Chinese leek (Allium tuberosum) significantly suppressed the mycelial growth of B. dothidea and inhibited the incidence of apple ring rot postharvest. However, the mechanism underlying the inhibitory role of DT against B. dothidea is not fully understood. Comparing the control and the DT-treated B. dothidea mycelial transcriptomes revealed that heat shock protein 20 (Hsp20) strongly responded to DT treatment. This study identified four Hsp20 genes throughout the B. dothidea genome (BdHsp20_1-4). Each BdHsp20 gene had a conserved ACD with a variable N-terminal region and a short C-terminal extension. The segmental duplication event has contributed to the expansion of the BdHsp20 gene family. Compared to the wild-type strain, the CRISPR/Cas9 gene-edited BdHsp20 mutant (ΔBdHsp20) decreased the mycelial growth by 55.95% and reduced the disease symptom in postharvest apple fruit by 96.34%. However, the BdHsp20 complemented strain (ΔBdHsp20_C) significantly restored the growth and pathogenicity, which suggested that the BdHsp20 gene was closely involved in the growth and pathogenicity of B. dothidea. This study would accelerate the exploration of the molecular mechanism of the inhibitory effect of DT against B. dothidea and also provide new insights for the management of apple ring rot disease.
