Morphological and molecular characterisation of Campylocarpon and Cylindrocarpon spp. associated with black foot disease of grapevines in Uruguay
Six phylogenetic groups were found that matched six previously known taxa and were supported by morphological characteristics, the first step towards a better understanding and management of black foot disease in local conditions.
Simultaneous and successive inoculations of yeasts and lactic acid bacteria on the fermentation of an unsulfited Tannat grape must
One Oenococcus oeni strain Lalvin VP41™ was inoculated with two Saccharomyces cerevisiae strains either simultaneously, three days after the yeast inoculation, or when alcoholic fermentation was close to finish, and early bacterial inoculations with each yeast strain allowed for the growth of the bacterial populations, and the length of malolactic fermentation was reduced to six days.
Diversity of fungal latent pathogens and true endophytes associated with fruit trees in Uruguay
It is demonstrated that apple, pear, blueberry and peach healthy shoots can host many known endophytic fungi along with potential wood disease‐causing fungi that should be regarded as latent pathogens.
Pangenome of Serratia marcescens strains from nosocomial and environmental origins reveals different populations and the links between them
A pangenome-based approach is used to apply whole genome multilocus sequence type schemes to assess whether there is an association between source and genotype, aiming at differentiating between isolates from nosocomial sources and the environment, and between strains reported as PGPR from other environmental strains.
Characterization of Botryosphaeriaceae species associated with grapevines in Uruguay
Isolates obtained from adult grapevines showing symptoms of die-back and esca in vineyards from all grape-growing regions of Uruguay and also from canes of asymptomatic mother plants in a commercial nursery confirmed the presence of Lasiodiplodia theobromae and Neofusicoccum australe and N. kwambonambiense.
Botryosphaeriaceae species associated with wood diseases of stone and pome fruits trees: symptoms and virulence across different hosts in Uruguay
The fact that fungal isolates obtained from one host could cause disease symptoms also in some of the alternative hosts suggests that cross infections are possible between apple, pear and peach trees.
Diversity and virulence of Diaporthe species associated with wood disease symptoms in deciduous fruit trees in Uruguay
Several Diaporthe species are recognized as causal agents of many plant disease symptoms, including twig and branch cankers, dieback, shoot blight, and root and fruit rots. In Uruguay, the proximity
Phaeomoniella chlamydospora and Phaeoacremonium spp. in grapevines from Uruguay.
Molecular diagnosis is potentially a useful method to assess the health of mother grapevines and some of other fungi frequently isolated from diseased vine tissues frequently tested positive for one of the fungi.
Phomopsis cotoneastri as a Pathogen Associated with Trunk Cankers and Death of Young Apple Trees cv. Cripps Pink
This is the first report of Phomopsis cotoneastri as a pathogen isolated from sunken cankers in trunks of young apple trees cv. Cripps Pink that had died in the first year after planting. Phomopsis
Dual selection of Beauveria bassiana strains and complex substrate media for the massive production of submerged propagules with activity against the eucalyptus bronze bug Thaumastocoris peregrinus
The proposed dual selection of strain and a complex substrate, and the procedures leading to the production of a dry preparation, allowed for high viability and virulence of the fungal spores of three strains.
