Nei panni dell'altro. Studi sul travestimento "intersessuale" in Grecia antica.
Le pratiche di travestimento intersessuale nel mondo antico forniscono una chiave di lettura non secondaria di una particolare rappresentazione dellââaltroâin unâottica di genere. Agendo attraverso il simbolico, esse offrono un paradigma significativo delle caratteristiche distintive che le societĂ antiche attribuivano ai sessi e al genere in un dato contesto. Inteso come fatto rituale ed elemento di costume, il fenomeno Ăš stato analizzato con gli strumenti metodologici dellâantropologia storica, applicata allo studio di talune esemplificazioni scelte per ragioni dâinteresse e peculiaritĂ specifiche

La guerra dentro e fuori: giochi di genere tra Argo e Tegea
Telesilla e Marpessa. Argo e Tegea. Due leader, due poleis, salvate da gynaikes guerriere, la cui azione origina un rito âanomaloâ allâinterno della cittĂ . Nelle tradizioni analizzate, allâirruzione del femminile sulla scena maschile del conflitto, agito contro un nemico esterno alla cittĂ , corrisponde, allâinterno di questa, uno stravolgimento delle normali attribuzioni e funzioni di genere. Tali dinamiche di rovesciamento e ribaltamento allâinterno della polis vengono valorizzate e problematizzate da unâanalisi condotta seconda una prospettiva di genere
Cloning and expression analysis of kenaf (Hibiscus cannabinus L.) major lignin and cellulose biosynthesis gene sequences and polymer quantification during plant development
In order to apply state-of-the-art molecular breeding techniques in fibre crop it is necessary to have a good knowledge of major polymer biosynthesis gene sequences and their expression pattern. Polymerase chain reaction was employed to isolate sequences of the major genes for lignin and cellulose biosynthesis in a kenaf cultivar. CeSA, 4cl, c4h, cad, and ccr gene primers were designed according to their conservative regions; partial sequences of lignin and cellulose biosynthesis genes were obtained. One actin II gene sequence was also isolated from the kenaf genome as a housekeeping gene to be employed in qPCR analysis. Expression levels of genes c4h, cad and CeSA in bark and core from plants harvested at three different growth stages were evaluated. Using qPCR analyses it was found that the expression levels of the two biosynthesis lignin genes in bark tissues increased during plant growth, while a negative trend was recorded in core tissues. In both bark and core, the quantity of lignin was positively correlated to plant growth while cellulose content decreased
Colonization of Solanum melongena and Vitis vinifera Plants by Botrytis cinerea Is Strongly Reduced by the Exogenous Application of Tomato Systemin
Plant defense peptides are able to control immune barriers and represent a potential novel
resource for crop protection. One of the best-characterized plant peptides is tomato Systemin (Sys)
an octadecapeptide synthesized as part of a larger precursor protein. Upon pest attack, Sys interacts
with a leucine-rich repeat receptor kinase, systemin receptor SYR, activating a complex intracellular
signaling pathway that leads to the wound response. Here, we demonstrated, for the first time,
that the direct delivery of the peptide to Solanum melongena and Vitis vinifera plants protects from the
agent of Grey mould (Botrytis cinerea). The observed disease tolerance is associated with the increase
of total soluble phenolic content, the activation of antioxidant enzymes, and the up-regulation of
defense-related genes in plants treated with the peptide. Our results suggest that in treated plants,
the biotic defense system is triggered by the Sys signaling pathway as a consequence of Sys interaction
with a SYR-like receptor recently found in several plant species, including those under investigation.
We propose that this biotechnological use of Sys, promoting defense responses against invaders,
represents a useful tool to integrate into pest management programs for the development of novel
strategies of crop protection
Des femmes en action
Diriger un chĆur, faire du commerce, dĂ©cider, conseiller ou faire la guerre sont autant de pratiques qui ne sont pas rĂ©servĂ©es aux hommes : la reconnaissance des qualitĂ©s et des compĂ©tences qui permettent d'assumer de façon efficace une fonction suit des logiques propres aux diffĂ©rents contextes et dĂ©passe une simple opposition entre femmes et hommes grecs. Par la pratique d'une anthropologie du genre, l'ouvrage offre une lecture renouvelĂ©e de ces contextes sociaux, Ă©conomiques et politiques
NOT ONLY SYSTEMIN: PROSYSTEMIN HARBOURS OTHER ACTIVE REGIONS ABLE TO PROTECT TOMATO PLANTS
Prosystemin is a 200-amino acid precursor expressed in Solanaceae plants which releases at the C-terminal part a peptidic hormone called Systemin in response to wounding and herbivore attack. We recently showed that Prosystemin is not only a mere scaffold of Systemin but, even when deprived of Systemin, is biologically active. These results, combined with recent discoveries that Prosystemin is an intrinsically disordered protein containing disordered regions within its sequence, prompted us to investigate the N-terminal portions of the precursor, which contribute to the greatest disorder within the sequence. To this aim, PS1-70 and PS1-120 were designed, produced, and structurally and functionally characterized. Both the fragments, which maintained their intrinsic disorder, were able to induce defense-related genes and to protect tomato plants against Botrytis cinerea and Spodoptera littoralis larvae. Intriguingly, the biological activity of each of the two N-terminal fragments and of Systemin is similar but not quite the same and does not show any toxicity on experimental non-targets considered. These regions account for different anti-stress activities conferred to tomato plants by their overexpression. The two N-terminal fragments identified in this study may represent new promising tools for sustainable crop protection
