There is limited knowledge about the relationships of epiphytic microbiomes associated with phyllosphere different Vitis vinifera cultivars in same vineyard and terroir. To address this research gap, we investigated microbiome compositionof 36 grapevine genotypes grown plant sections during growing season. Using high-throughput NGS-based metagenomic analysis targeting ITS2 V4 regions 16S riboso...

ABSTRACT Reduced-pathogenicity mutants of the avocado fruit pathogen Colletotrichum gloeosporioides isolate Cg-14 (teleomorph: Glomerella cingulata) were generated by insertional mutagenesis by restriction enzyme-mediated integration (REMI) transformation. Following seven transformations, 3,500 hygromycin-resistant isolates were subjected to a virulence assay by inoculation on mesocarp and peri...

ABSTRACT Isolates of Colletotrichum spp. from diseased strawberry fruit and crowns were evaluated to determine their genetic diversity and the etiology of the diseases. Isolates were identified to species using polymerase chain reaction primers for a ribosomal internal transcribed spacer region and their pathogenicity was evaluated in bioassays. Isolates were scored for variation at 40 putative...

Endophytic fungi are inhabitants of plants, living most part of their lifecycle asymptomatically which mainly confer protection and ecological advantages to the host plant. In this present study, 48 endophytic fungi were isolated from the leaves of three medicinal plants and characterized based on ITS2 sequence - secondary structure analysis. ITS2 secondary structures were elucidated with minim...

A total of 39 endophytic fungi have been isolated from Viguiera arenaria and Tithonia diversifolia, both collected in São Paulo State, Brazil. The isolates were identified based on their ribosomal DNA sequences. The ethyl acetate (EtOAc) extracts of all endophytic fungi were evaluated for their antimicrobial, antiparasitic and antitumoral activity. Antimicrobial screening was conducted using an...

This study evaluated the effect of growing site environmental conditions on apple fruit quality. Experimental orchards with ‘Gala’ and ‘Fuji’ strains were established in subtropical humid climate Southern Brazil, between 26° 28°S, sites São Joaquim, Caçador Vacaria, located 1415, 960, 971 m, respectively, above sea level. Fruit quality was assessed at harvest after storage from 5th through 8th ...
