Última Acetolactate synthase activity in Euphorbia heterophylla resistant to ALS- and protox- inhibiting herbicides Planta Daninha Xavier,E.; Oliveira,M.C.; Trezzi,M.M.; Vidal,R.A.; Diesel,F.; Pagnoncelli,F.D.; Scalcon,E.. The objective of this study was to determine the activity of the enzyme acetolactate synthase in biotypes of wild poinsettia (Euphorbia heterophylla) with multiple resistance to ALS- and Protox- inhibitors in the presence and absence of imazapyr, imazethapyr and nicosulfuron. We conducted in vitro assay of ALS enzyme extracted from plants of Vitorino, Bom Sucesso do Sul and Medianeira biotypes (with multiple resistance) and a susceptible population in the absence and presence of imazapyr, imazethapyr and nicosulfuron. In the absence of herbicides, biotypes with multiple resistance showed higher affinity for the substrate of the enzyme compared with the susceptible population. The herbicides imazapyr, imazethapyr and nicosulfuron had little effect on the... Tipo: Info:eu-repo/semantics/article Palavras-chave: Cross resistance; Wild poinsettia; Mechanism of resistance.

Antilisterial efficiency of three bacteriocins, viz, Nisin, Pediocin 34 and Enterocin FH99 was tested individually and in combination against Listeria mononcytogenes ATCC 53135. A greater antibacterial effect was observed when the bacteriocins were combined in pairs, indicating that the use of more than one LAB bacteriocin in combination have a higher antibacterial action than when used individually. Variants of Listeria monocytogenes ATCC 53135 resistant to Nisin, Pediocin 34 and Enterocin FH99 were developed. Bacteriocin cross-resistance of wild type and their corresponding resistant variants were assessed and results showed that resistance to a bacteriocin may extend to other bacteriocins within the same class. Resistance to Pediocin 34 conferred cross... Tipo: Info:eu-repo/semantics/article Palavras-chave: Listeria monocytogenes; Nisin; Pedioin 34; Enterocin FH99; Cross resistance.
