In this context, p...

Antigone’s tragic genome: transmission and mutations of the Theban myth

Long before gaining an unequivocal prominence in the production of all the great tragediographers of the Classical Period - who seem to have almost obsessively poured the ominous shadow of contemporary fratricidal struggles into their symbolic flow - the mythical saga of Thebes, based on the unfortunate line of succession of the royal family inaugurated by Cadmus, occurs in multiple narrative allusions, from th...

“Achilles: dismeasure figuration”

In the complex framework of the heroic figures of Greco-Latin mythology, Achilles appears as one of the most relevant references in antiquity. This exceptional popularity, which allowed the character to survive the erosion of oblivion and to exert on the imaginary incomparable influence, is due to the fact that Homer chose him as the protagonist of the Iliad, and guided the peculiar angle of view of the Trojan ...

“Aquiles, figuração da desmesura”

No enquadramento complexo das figuras heróicas da mitologia greco-latina, Aquiles surge como uma das referências mais relevantes da Antiguidade. Essa excepcional popularidade, que permitiu à personagem sobreviver à erosão do esquecimento e exercer incomparável influência sobre o imaginário, deve-se ao facto de Homero o ter escolhido como protagonista da Ilíada, e ter orientado pela intensidade passional da sua ...

Ritual e símbolo: a máscara na Grécia Antiga

Wheat Shoot Al, Fe, Mn and Zn Levels Are Influenced by Arbuscular Mycorrhiza Ex...

In the present study, the levels of Al, Fe, Mn and Zn in wheat shoots were quantified by inductively coupled plasma mass spectrometry (ICP-MS). Wheat was grown in an acidic soil with toxic levels of Mn and with intact or disrupted extraradical mycelium (ERM) as the arbuscular mycorrhizal fungi (AMF) inoculum source, resulting from the previous growth of O. compressus. In the presence of an intact ERM, toxic Mn ...

Arbuscular Mycorrhiza Extraradical Mycelium Promotes Si and Mn Subcellular Redi...

Abstract: Manganese (Mn) and aluminum (Al) toxicities are serious edaphic limitations to crop production in acidic soils. Excess Mn can be countered using a stress-adapted soil microbiota that establish symbiotic relationships with native plants. The arbuscular mycorrhizal fungi (AMF) associated with Lolium rigidum L. develop extraradical mycelia (ERM) that quickly colonize wheat and lead to greater shoot growt...
