Botryosphaeriaceae species associated with wood diseases of stone and pome fruits trees: symptoms and virulence across different hosts in Uruguay

Diversity of fungal latent pathogens and true endophytes associated with fruit trees in Uruguay

“…The reduced number of species and isolates of this family, much lower than obtained from forest trees (Pérez, Wingfield, Slippers, Altier, & Blanchette, ), could reflect that the highly intervened orchard ecosystem is not favourable for the occurrence of endophytic colonization by members of this family. Additionally, the fact that B. dothidea was absent as a latent pathogen from apple twigs but prominent in apple symptomatic shoots and branches (Sessa, Abreo, Bettucci, & Lupo, ) might indicate that its entrance into shoots is not passive through natural openings like lenticels but dependant on wounds like those caused by wind or pruning as previously reported (Rolshausen et al., ; Rooney‐Latham, Escalen, & Gubler, ; Úrbez‐Torres, Bruez, Hurtado, & Gubler, ; Úrbez‐Torres & Gubler, ).…”

“…While N. parvum and N. australe showed extensive necrosis and therefore should be considered as latent pathogens in apple and pear, respectively, both species had been isolated before from symptomatic branches of apple and pear trees, and they had also shown extensive cankers when inoculated in twigs of both hosts under field conditions in Uruguay (Sessa et al., ). Taken all together, these results point at these two species of Botryosphaeriaceae as low‐frequency latent pathogens of the highest virulence.…”

Chemical characterization and antioxidant capacity of ‘Cambui’ (Myrciaria tenella) products

“…The 'Cambui' tree (Myrciaria tenella) belongs to the Myrtaceae family, originating from South America (Sessa et al, 2016), South (Belem et al 2016;Tonetti & Biondi, 2016;Cordero et al 2016) and Southeast states of Brazil, it can also be found in the Northeast of the country (Silva et al, 2012), as in areas of the 'Chapada Diamantina', Bahia State. It is mainly used as an ornamental plant and its wood is used for fence posts, tools and firewood (Lorenzi 2000).…”

Pseudofusicoccum sp. causing shoot canker in peach in Uruguay

“…micromorphological characteristics, molecular sequence data from the internal transcribed spacer region (ITS) and part of the translation elongation factor 1-alpha gene (EF1-α) and pathogenicity assays. The isolation method was as reported by Sessa et al (2016). Isolate Fi2364 was obtained from Early Grande peach shoots showing cankers with gummosis and it was recovered together with isolates later identified as Neofusicoccum parvum.…”

“…On the other hand, species of this genus are frequently reported as endophytes (Sharma et al 2013;Mehl et al 2011) or as low virulence pathogens co-occurring with other Botryosphaeriaceae species causing disease symptoms. Co-occurrence with high virulence pathogens include species such as Neofusicoccum mangroviorum (Jami et al 2018), Lasiodiplodia theobromae (Silveira et al 2017), Botryosphaeria dothidea and N. parvum (Marques et al 2013;Rolim et al 2020;Sessa et al 2016). This could mean that in most cases Pseudofusicoccum cannot be signaled as solely responsible for the symptoms observed in the damaged tissues.…”
