    Description: Organic agriculture sparks a lively debate on its potential health and environmental benefits. Comparative studies often investigate the response of crops to organic farming through targeted approaches and within a limited experimental work. To clarify this issue, the transcriptomic profile of a cultivar of the potato grown for two years under organic and conventional farming was compared with the profile of an experimental clone grown in the same location of Southern Italy for one year. Transcriptomic raw data were obtained through Potato Oligo Chip Initiative (POCI) microarrays and were processed using unsupervised coupling multivariate statistical analysis and bioinformatics (MapMan software). One-hundred-forty-four genes showed the same expression in both years, and 113 showed the same expression in both genotypes. Their functional characterization revealed the strong involvement of the farming system in metabolism associated with the nutritional aspects of organic tubers (e.g., phenylpropanoid, flavonoid, glycoalcaloid, asparagine, ascorbic acid). Moreover, further investigation showed that eight of 42,034 features exhibited the same trend of expression irrespective of the year and genotype, making them possible candidates as markers of traceability. This paper raises the issue regarding the choice of genotype in organic management and the relevance of assessing seasonal conditions effects when studying the effects of organic cultivation on tuber metabolism.

    Description: The volume, dedicated to the 44th International Conference of the Italian Union for Drawing, investigates the theme of ‘Transitions’, which particularly effectively represents our time and the current condition of the discipline of Drawing. The term, beyond its generic meaning of an intermediate stage in a process in which a condition changes from one state to another, has always been used in various fields, from music to geophysics. In fact, the disciplines of drawing have always been confronted with themes and issues relating to transitions from one condition to another. The history of representation tells us of transformations, even epochal ones, relating to ‘drawing’, with all that such transitions entail: suffice it to think of the evolution of forms of representation, of instrumental apparatuses, of the mutability of supports, of the analogical-digital transition underway, of the new modes of communication on platforms, of the hypertrophic offer of images also on the net that confirms Guy Debord’s intuitions relating to the new spectacularisation of society. Similarly, representation triggers transitions in the prefiguration and communication of design, the anticipation and foreshadowing of future events.The challenges posed by the digital pose open questions whose scope can only be glimpsed, such as the relationship between drawing and the act of modelling, and the construction of new paradigms of visual language and communication. ‘Transitions’, almost implicitly, points to possible futures, the evolution of technique and the search for new modes of expression; at the same time, however, it can suggest silences and reflections in a process of connection between history, theory, criticism and construction.
