Incidence of Garlic common latent virus in Argentina, and phylogenetic and recombination analyses of isolates PAB
Torrico,Ada Karina; Celli,Marcos Giovani; Conci,Luis Rogelio; Conci,Vilma Cecilia.
The objective of this work was to estimate the incidence and prevalence of Garlic common latent virus (GarCLV) in the main production regions of garlic (Allium sativum) in Argentina, and to perform phylogenetic and recombination analyses in isolates from these regions. Leaf samples (3,050) were taken from four garlic commercial types, in 13 departments of the four main garlic-producing provinces of Argentina, in a 1,175-ha sampling area. Virus infection was evaluated with DAS-Elisa test using specific antiserum, and the phylogenetic and recombination analyses were done with capsid protein (CP) nucleotide sequence of seven GarCLV isolates from the provinces. The incidence of GarCLV in the evaluated provinces varied between 6.7 and 22% of the samples,...

Penicillium expansum versus antagonist yeasts and patulin degradation in vitro BABT
Coelho,Alexandre Rodrigo; Celli,Marcos Giovani; Ono,Elisabete Yurie Sataque; Wosiacki,Gilvan; Hoffmann,Fernando Leite; Pagnocca,Fernando Carlos; Hirooka,Elisa Yoko.
Taking into account the preliminary antagonistic/biodegradation property showed by Pichia membranifaciens and Sporobolomyces roseus, which decreased the initial patulin concentration of 588.4 to 290.0 µg/mL, ability of P. ohmeri 158 in biocontrol against Penicillium expansum and patulin decrease in vitro was performed. The culture supernatant of P. ohmeri 158 was effective against 66.17% micelial growth, indicating antibiosis related with the killer phenomenon. The initial patulin concentration of 223 µg in the presence of P. ohmeri 158 cells was decreased over 83% of the original concentration, when incubated at 25ºC/2 days and > 99% after 5 days incubation time, with undetectable patulin level after 15 days. The initial pH 4.0 decreased to pH 3.3...
