Ethylene: Management and breeding for postharvest quality in vegetable crops. A review.

Ethylene is a two-carbon gaseous plant growth regulator that involved in several important physiological events, including growth, development, ripening and senescence of fruits, vegetables, and ornamental crops. The hormone accelerates ripening of ethylene sensitive fruits, leafy greens and vegetables at micromolar concentrations, and its accumulation can led to fruit decay and waste during the postharvest stage. Several strategies of crops management and techniques of plant breeding have been attempted in the last decades to understand ethylene regulation pathways and ethylene-dependent biochemical and physiological processes, with the final aim to extend the produce shelf-life and improve the postharvest quality of fruits and vegetables.

Effect of slicing and storage temperatures on biochemical aspects of membrane integrity in two different genotypes of tomato.

Background: Fresh-cut vegetables are subjected to multiple stressing agents including: (i) slicing, which induces cellular decompartmentalization; (ii) low refrigeration temperatures, responsible for chilling injury in the most sensitive products (e.g. tomatoes), and (iii) storage time because tissue senescence and aging can occur and reduce the shelf-life.

The Role of Regulatory Agencies in Agenda-Setting Processes: Insights from the Italian Response to the COVID-19 Infodemic.

International organizations such as the WHO have worked to raise awareness of the massive infodemic that accompanied the COVID-19 outbreak and made it hard for people to find trustworthy sources of information and reliable guidance for their decisions. Our contribution focuses on the Italian case, where the Communications Regulatory Authority (AGCOM) was able to act as first mover in its field so as to strategically frame the problem of disinformation in the absence of a pre-existing policy intervention. An emerging body of research shows that the activity of formally independent regulators is not necessarily limited to the implementation of delegated regulatory competencies.
