    The application of biotechnology and genetics to plant science and agronomy is at the basis of the new breeding techniques, including Genome Editing (GE). A choice experiment was undertaken to investigate Italian consumers’ preferences for bread made with gene-edited wheat. Respondents were randomly assigned one of the two versions of a questionnaire, including either a neutral or negatively biased definition of GE. Results demonstrate that the information effect is limited, which confirms that consumers are struggling to understand new breeding techniques. The scientific community should therefore develop better communication strategies for society to comprehensively understand biotechnologies and support policymakers in the definition of informed regulations.

    Three water-soluble glucans (PELPS-A1, PELPS-A2, and PELPS-A3) purified from the hot water extract of the basidiomata of an edible mushroom Pleurotus eryngii var. elaeoselini by chromatography on DEAE-cellulose 32 and Sephadex G-100 column were found to consist of only D-glucose as monosaccharide constituent. Structural investigation was carried out by acid hydrolysis, periodate oxidation, and NMR experiments (1H-NMR, 13C-NMR, DQF-COSY, TOCSY, ROESY, HMQC, and HMBC). On the basis of these experiments, the structures of the repeating unit of the three isolated polysaccharides were established as follows: (1) PELPS-A1: {[→3)-α-D-Glcp-(1→]3→4)-α-D-Glcp-(1→2)-α-D-Glcp-(1→6)-α-D-Glcp-(1[→6)-β-D-Glcp-(1→]2}n 6 ↑ 1 α-D-Glcp (2) PELPS-A2: [→6)-β-D-Glcp-(1→6)-β-D-Glcp-(1→6)-β-D-Glcp-(1→]n 3 ↑ 1 β-D-Glcp (3) PELPS-A3: [→6)-α-D-Glcp-(1→6)-α-D-Glcp-(1→6)-α-D-Glcp-(1→]n The dried basidiomata of P. eryngii var. elaoselini were tested for their antioxidant activity by DPPH and hydroxyl radical scavenging assays. The crude extract has shown a SC50 of 1.4 mg/mL for DPPH test while a SC50 of 5.7 mg/mL was observed for hydroxyl radical scavenging activity test. The antioxidant activity of PELPS-A1, PELPS-A2, and PELPS-A3, evaluated as hydroxyl radical scavenging activity, was similar and significant, suggesting their use as antioxidants.
