Fungal endophytic communities associated to the phyllosphere of grapevine cultivars under different types of management

et al. 2016

a b s t r a c tFungal endophytes present in different asymptomatic grapevine plants (Vitis vinifera L.) located in different vineyards within Alentejo, a highly important viticulture region in Portugal, were identified in this study. Sampled grapevine plants included the three most representative cultivars in the region, Syrah, Cabernet Sauvignon, and Aragonez, growing under two different modes of management, conventional and biological. Sixteen fungal taxa were identified through sequencing of the internal transcribed spacer region. Total number of endophytic fungi isolated showed significant differences both in management mode and in cultivars, with higher numbers in grapevines under conventional mode and from Syrah cultivar. The composition of fungal endophytic communities did not show significant differences among cultivars, but differences were observed between fungal communities isolated from grapevines under biological or conventional modes. The most fungal taxa isolated from grapevines cultivated under biological mode were Alternaria alternata, Cladosporium sp., and Nigrospora oryzae, and under conventional mode Botrytis cinerea, Epicoccum nigrum, and Epicoccum sp. These differences suggest that the different products used in grapevine production have impacts in fungal endophytic composition. Further investigation of the identified fungi with respect to their antagonistic characteristics and potential use in plant protection to ensure food safety is now in course.

“…Fungal contamination is suspected due to quite high moisture content (> 8%) and the slow sun drying process of the commodities. Several species of Penicillium are known to contaminate foods such as P. verrucosum on dried foods and cereals, P. nordicum on fermentation of meat and cheese which potential in OTA production (Larsen et al, 2001;Castella et al, 2002;Cabanes et al, 2010).…”

“…Species of Aspergillus, which produce OTA in cocoa are mainly Aspergillus carbonarius and A. niger (Mounjouenpou et al, 2008;Cabanes et al, 2010). Other important species regarding potential ochratoxin A production in coffee, rice, beverages and other foodstuffs are A. ochraceus, A. westerdijkiae, and A. steynii .…”

“…Other important species regarding potential ochratoxin A production in coffee, rice, beverages and other foodstuffs are A. ochraceus, A. westerdijkiae, and A. steynii . While from genus Penicillium, at the moment only two species accepted as OTA producing, i.e., P. verrucosum and P. nordicum (Larsen et al, 2001;Castella et al, 2002;Cabanes et al, 2010). While according to Vega et al, (2006) among 11 Penicillium species endophytic in coffee plants, four isolates produced OTA A, i.e., P. brevicompactum, P. crustosum, P. olsonii and P. oxalicum.…”

The presence of Penicillium in cocoa and coffee beans, and dried cassava are detrimental due to its ability in ochratoxin A (OTA) production which carcinogenic and mutagenic to human. Objectives of this study were to isolate and identify Penicillium from cocoa, coffee beans and dried cassava in Yogyakarta by morphological and molecular characteristics, as well as to observe the ability of these isolates in OTA production on Yeast Extract Sucrose Agar (YES) medium. In this study, morphological characteristics were mainly based on the growth of isolates on identification media, while molecular characteristics were based on the similarity of PCR products using ITS4 and ITS5 as primers. OTA was detected by ELISA and UPLC methods. The result showed that 15 of 16 representative isolates obtained during this study were identified as Penicillium citrinum, one of the representative isolate from cocoa beans was identified as Penicillium paneum. Surprisingly, 13 among 15 of the obtained P. citrinum isolates from cocoa and coffee beans were positive in the production of OTA in YES medium, at the concentration of 4.64 to 25.26 µg/g media, while OTA was not detected in YES grown media by P. paneum and two isolates of P. citrinum from dried cassava. Conclusion of this study, the most found species Penicillium in cocoa and coffee beans were belong to P. citrinum which likely have a capability in the production of OTA.

“…In turn this puts consumers of fungal infected crops at risk of poor nutrition, which can further render them vulnerable to diseases. Important mycotoxins that may be found in maize include T-2 toxins and fumonisns, mainly produced by Fusarium species (Akande et al 2006: 400), aflatoxins, produced by Aspergillus species (Akande et al 2006: 399) and ochratoxins, mainly produced by Penicillium and some Aspergillus species such as Aspergillus niger (Cabañes et al 2010(Cabañes et al : 1112.…”

‘There is death in the pot!’Exploring the agency of faith communities and the bible as an asset in addressing mycotoxin contamination of food and animal feed

This paper is an exploration of the contribution that faith communities can make towards stopping the vulnerability of poor communities to illnesses caused by the consumption of mycotoxin contaminated foods. Mycotoxins are associated with illnesses such as the dysfunction of organs and cancer. The article draws upon available literature, specifically from the author's study on home stored maize in Rungwe district, Tanzania in 2009, which revealed exceedingly high levels of mycotoxins in maize from subsistence farm households. Using the African Religious Health Assets Programme's (ARHAP) approach as a theoretical framework, the author argues for the engagement of faith communities and the Bible in stopping the consumption of mycotoxin contaminated foods.
