“…However, our work highlighted a few instances of close host associations. Prior to this study, C. punicae had been reported causing wood canker on pomegranate trees in California, Cyprus, and Iran (Peduto Hand et al 2014, Samouel & Kanetis 2016, Mahdikhani & Davoodi 2017), pomegranate collar rot in Greece (Palavouzis et al 2015), and pomegranate fruit rot in South Africa (Venter et al 2017). Cytospora punicae was only recovered from pomegranate trees in this study, supporting this species as host specific despite a wide geographical distribution.…”

Cytospora species are destructive canker and dieback pathogens of woody hosts in natural and agroecosystems around the world. In this genus, molecular identification has been limited due to the paucity of multi-locus sequence typing studies and the lack of sequence data from type specimens in public repositories, stalling robust phylogenetic reconstructions. In most cases a morphological species concept could not be applied due to the plasticity of characters and significant overlap of morphological features such as spore dimensions and fruiting body characters. In this study, we employed a molecular phylogenetic framework with the inclusion of four nuclear loci (ITS, translation elongation factor 1-alpha, actin, and beta-tubulin) to unveil the biodiversity and taxonomy of this understudied important genus of plant pathogens. Phylogenetic inferences based on 150 Californian isolates revealed 15 Cytospora species associated with branch and twig cankers and dieback of almond, apricot, cherry, cottonwood, olive, peach, pistachio, plum, pomegranate, and walnut trees in California. Of the 15 species recovered in this study, 10 are newly described and typified, in addition to one new combination. The pathogenic status of the newly described Cytospora species requires further investigation as most species were associated with severe dieback and decline of diverse and economically important fruit and nut crops in California.

“…Although in Spain has been reported C. annulata [32], the most widespread species is C. punicae. This latter has been reported in various pomegranate cultivation areas such as United States, South Africa, Greece, Cyprus, and Italy [6,[66][67][68][69]. Postharvest fruit decay is identifiable by circular soft lesions of the rind, creamy-brownish colored, and centrally darker; related subcutaneous area shows a yellowish and corky appearance.…”

Due to well-known nutraceutical properties, pomegranate (Punica granatum L.) cultivation is recently increasing in various areas of the world including Italy. Fungal diseases are the major causes of postharvest yield and economic losses. Most of the fungi infect pomegranates in the field during the blooming stage remaining latent until fruit ripening, others infect fruit during harvest and postharvest handling through rind injuries. Main postharvest fungal diseases of pomegranates are gray and blue molds caused by Botrytis spp. and Penicillium spp., respectively, black heart and black spot due to Alternaria spp., anthracnose related to species ascribable to Colletotrichum genus, and Coniella rot, due to Coniella granati. Few fungicides are allowed for pre- and postharvest treatments, making it extremely difficult to control fungal infections. In this scenario, especially in organic fruit production, alternative control means may be a desirable solution to reduce pomegranate losses during the production chain. This chapter focuses on the most important postharvest diseases of pomegranates and possible strategies and means to reduce spoilage.

“…On fruits, among Cytospora species, C. annulata was isolated from harvested pomegranates, but it did not exhibit pathogenicity, as Koch’s postulates were not fulfilled [ 16 ]. In contrast, C. punicae was recently cited as a causal agent of postharvest fruit rot [ 30 , 92 ].…”

Pomegranate (Punica granatum L.) is an emerging crop in Italy and particularly in southern regions, such as Apulia, Basilicata, and Sicily, due to favorable climatic conditions. The crop is affected by several pathogenic fungi, primarily in the field, but also during postharvest phases. The most important postharvest fungal diseases in pomegranate are gray and blue molds, black heart and black spot, anthracnose, dry rot, and various soft rots. The limited number of fungicides allowed for treatment in the field and the lack of postharvest fungicides make it difficult to control latent, quiescent, and incipient fungal infections. Symptomatic pomegranates from southern Italy were sampled and isolated fungi were morphologically and molecularly characterized. The data obtained revealed that various species of Penicillium sensu lato (including Talaromyces genus), Alternaria spp., Coniella granati, and Botrytis cinerea were the principal etiological agents of postharvest pomegranate fruit diseases; other relevant pathogens, although less represented, were ascribable to Aspergillus sect. nigri, Colletotrichum acutatum sensu stricto, and Cytospora punicae. About two thirds of the isolated pathogens were responsible for latent infections. The results obtained may be useful in planning phytosanitary control strategies from the field to storage, so as to reduce yield losses.
