Abstract
Botryosphaeria dieback is a grapevine trunk disease that affects all viticulture regions of the world. Species of the genus Lasiodiplodia have been reported as pathogenic toward grapevine in several growing regions and have also been previously reported from Portuguese vineyards. Species in this genus, particularly Lasiodiplodia theobromae, have been reported in previous studies to be more aggressive than other Botryosphaeriaceae species most commonly associated with Botryosphaeria dieback. The aim of this study was to assess the response of some of the more representative cultivars planted throughout Portuguese vineyards, 'Touriga Nacional,' 'Touriga Franca,' 'Alvarinho,' 'Aragonez' (= 'Tempranillo'), and 'Cabernet Sauvignon,' by performing artificial inoculations with Lasiodiplodia spp. collected in different geographic locations worldwide. Two experiments, one that involved inoculating 2-year-old grapevines kept in greenhouse-controlled conditions with six isolates of L. theobromae and one isolate of L. mediterranea and one that involved inoculating 7-year-old field-grown grapevines with two isolates of L. theobromae, were conducted twice. We assessed the response of the cultivars by evaluating the length of lesions caused by the isolates 5 months after inoculation. The results showed that all isolates studied were able to infect the annual shoots because they were always reisolated and produced internal wood discoloration. Significant differences were found for all isolate-cultivar combinations. In both experiments, Touriga Nacional showed the largest lesions and while Aragonez recorded the smallest lesions of the cultivars inoculated with Lasiodiplodia spp. In general, Portuguese isolates were more aggressive than those from Peru, which were mildly aggressive. These results are a first insight into the response of selected Portuguese cultivars to Lasiodiplodia species, which are present in Portugal but not commonly associated with Botryosphaeria dieback. This research contributes to our knowledge of the impact that Botryosphaeria dieback causal agents have on crucial national cultivars, which may help winegrowers not only manage current cultural practices but also optimize decision making when planning new vineyards.

Abstract
Tree trunk cankers represent serious fungal diseases that pose significant threats to Chinese hickory trees (Carya cathayensis). To characterize the pathogen diversity associated with this disease, tissues were collected between 2016 and 2018 from the primary Chinese hickory plantation regions. A total of 97 cultures were isolated from trees in six towns (Longgang, Qingliangfeng, Changhua, Tuankou, Taiyang Town, and Lin'an urban area) within the Linan district, where 60% of Chinese hickory tree yields originate. The isolated cultures caused cankers on Chinese hickory tree branches, but infections did not occur on fruits or leaves under tested conditions. Combined morphological observations and phylogenetic analysis of multiple genes (ITS, β-tubulin, and EF) indicated that five Botryosphaeriaceae species were recovered, including 89 isolates of Botryosphaeria dothidea, 4 isolates of Botryosphaeriaceae fabicerciana, 1 isolate of Botryosphaeriaceae qingyuanensis, 1 isolate of Botryosphaeriaceae corticis, and two isolates of Lasiodiplodia theobromae. B. dothidea was the most prevalent, and this is the first report of B. corticis, B. qingyuanensis, and L. theobromae infections in Chinese hickory trees. We investigated the mycelial growth, spore germination, and pathogenicity of these species at different temperatures. L. theobromae grew the fastest and B. cortices grew the slowest on potato dextrose agar. The optimum temperature of spore germination for all species was 30°C. L. theobromae was the most virulent species, followed by B. dothidea and B. qingyuanensis, then B. fabicerciana, and finally B. cortices. These new insights into fungal pathogen diversity provide critical new information to understand and manage tree trunk cankers of Chinese hickory.

Abstract
The genus Lasiodiplodia has been reported from several grape growing regions and is considered as one of the fastest wood colonizers, causing Botryosphaeria dieback. The aim of this study was to (i) evaluate the efficacy of Esquive®, a biocontrol agent, on vineyard pruning wound protection, applied single or, in a combined protection strategy with a new site-targeted copper-based treatment (LC2017), and (ii) compare their efficacy with chemical protection provided by the commercially available product, Tessior®. For two seasons, protectants were applied onto pruning wounds, while LC2017 was applied throughout the season according to the manufacturer's instructions. Pruning wounds of two different cultivars were inoculated with three isolates of Lasiodiplodia spp. Efficacy of the wound protectants, varied between both years of the assay and according to the cultivar studied but were able to control the pathogen to some extent. The application of LC2017 did not show clear evidence of improving the control obtained by the sole application of the other products tested. Nevertheless, LC2017 showed a fungistatic effect against Lasiodiplodia spp., in vitro, and has previously shown an elicitor effect against grapevine trunk diseases. Therefore, this combination of two protection strategies may constitute a promising long-term approach to mitigate the impact of Botryosphaeria dieback.

Abstract
English walnut (Juglans regia L.) is considered an economically important fruit crop worldwide. In Spain, little attention has been given to walnut diseases owing to the minor economic importance of the walnut crop in the country until recently. In 2017, typical symptoms of branch dieback and shoot blight of English walnut were observed in southern Spain. From 2017 to 2018, 10 commercial walnut orchards showing disease symptoms were surveyed. Botryosphaeriaceae and Diaporthe fungi were consistently isolated from affected shoots. Cytospora isolates were also recovered with minor relevance. Representative isolates of each fungal group were characterized based on colony and conidial morphology, optimum growth temperature, and comparison of DNA sequence data from the internal transcribed spacer, elongation factor 1-α, and β-tubulin genomic areas. Pathogenicity tests were performed on detached and attached shoots and on detached fruit by inoculating them with mycelial plugs. Botryosphaeriaceae and Diaporthe isolates had higher optimum growth temperatures (≈25 to 27°C) than Cytospora sp. (19.5°C). The following species were identified: Botryosphaeriaceae: Botryosphaeria dothidea, Diplodia seriata, Dothiorella sarmentorum, Dothiorella sp., Neofusicoccum mediterraneum, and N. parvum; Diaporthe: Diaporthe neotheicola, Dia. rhusicola, Diaporthe sp., and Phomopsis amygdali; and Cytospora sp. Botryosphaeriaceae isolates were the most aggressive fungi to walnut in all tissues evaluated, followed by Diaporthe isolates and Cytospora sp. N. parvum was the most virulent among the remaining species tested in any of the tissues evaluated, followed by B. dothidea or N. mediterraneum. This work is the first report to identify the fungal species causing this complex disease of English walnut in Spain and Europe.

Abstract
Lasiodiplodia theobromae is one of the most aggressive agents of the grapevine trunk disease Botryosphaeria dieback. Through a dual RNA-sequencing approach, this study aimed to give a broader perspective on the infection strategy deployed by L. theobromae, while understanding grapevine response. Approximately 0.05% and 90% of the reads were mapped to the genomes of L. theobromae and Vitis vinifera, respectively. Over 2500 genes were significantly differentially expressed in infected plants after 10 dpi, many of which are involved in the inducible defense mechanisms of grapevines. Gene expression analysis showed changes in the fungal metabolism of phenolic compounds, carbohydrate metabolism, transmembrane transport, and toxin synthesis. These functions are related to the pathogenicity mechanisms involved in plant cell wall degradation and fungal defense against antimicrobial substances produced by the host. Genes encoding for the degradation of plant phenylpropanoid precursors were up-regulated, suggesting that the fungus could evade the host defense response using the phenylpropanoid pathway. The up-regulation of many distinct components of the phenylpropanoid pathway in plants supports this hypothesis. Moreover, genes related to phytoalexin biosynthesis, hormone metabolism, cell wall modification enzymes, and pathogenesis-related proteins seem to be involved in the host responses observed. This study provides additional insights into the molecular mechanisms of L. theobromae and V. vinifera interactions.

Abstract
Phytotoxic metabolites produced in liquid culture by six species of Lasiodiplodia isolated in Brazil and causing Botryosphaeria dieback of grapevine were chemically identified. As ascertained by LC/MS, L. brasiliense, L. crassispora, L. jatrophicola, and L. pseudotheobromae produced jasmonic acid, and L. brasiliense synthesized, besides jasmonic acid, also (3R,4S)-4-hydroxymellein. L. euphorbicola and L. hormozganensis produced some low molecular weight lipophilic toxins. Specifically, L. euphorbicola produced (-)-mellein, (3R,4R)-(-)- and (3R,4S)-(-)-4-hydroxymellein, and tyrosol, and L. hormozganensis synthesized tyrosol and p-hydroxybenzoic acid. This is the first report on the production of the above cited metabolites from L. euphorbicola and L. hormozganensis. The phytotoxic activity of the metabolites produced is also discussed and related to the symptoms these pathogens cause in the grapevine host plants.

Abstract
Fungal species in the family Botryosphaeriaceae have been recently recognized as the most common fungi isolated from grapevine (Vitis vinifera) cankers in California. However, the role of these fungi in causing grapevine dieback as well as their status as canker-causing agents was unknown. Therefore, pathogenicity studies were conducted to determine their importance as grapevine pathogens in California. A total of 72 isolates representing all nine Botryosphaeriaceae species isolated from grapevine cankers from California were used in five different pathogenicity studies. Overall, experiments showed all nine Botryosphaeriaceae species able to infect both young and mature tissues as well as green shoots of the new vegetative growth causing cankers, vascular discoloration, and/or otherwise dark streaking of the wood. However, virulence varied among species. Lasiodiplodia theobromae was the most virulent species followed by Neofusicoccum luteum, N. parvum, and N. australe, all categorized as highly virulent. Botryosphaeria dothidea was considered intermediately virulent and Diplodia mutila, D. seriata, Dothiorella iberica, and D. viticola were shown to be weakly virulent. This study shows species of Botryosphaeriaceae to be much more important pathogens on grapevines than originally thought, and some of them, in view of their virulence, should be considered high risk for causing severe and rapid canker and dieback diseases in the grapevine industry in California.
