Overexpression of a specific P. vulgaris (PvGSTU2-2) isoenzyme improves dimethenamid tolerance of transgenic tobacco plants
Get PDFPlant glutathione transferases (GSTs) have a major role in plant herbicide detoxification system. PvGSTU2-2 has been isolated from leaves of Phaseolus vulgaris plants. The enzyme catalyses the conjugation of glutathione with chloroacetamide herbicides alachlor and metalachlor. In order to study in planta the ability of PvGSTU2-2 to detoxify chloroacetamide herbicides, we developed transgenic tobacco plants overexpressing PvGSTU2-2. The introgression of the transgene in the plant genome was confirmed by RT-PCR and the expression of PvGSTU2-2 with q-RTPCR analysis. In addition, it was verified that the transgenes codes functional proteins by measuring GST enzyme activity towards NBD-CI in transgenic lines. Three PvGSTU2-2 overexpressing lines were assayed for their tolerance towards the herbicide dimethenamid (chloroacetamide). Under in vivo conditions, T0 lines exhibited increased tolerance at 0,5 and 1 mg/L dimethenamid, with significantly increased shoot and root elongation compared to wild type plants. These results confirm that overexpression of PvGSTU2-2 in tobacco provides a way of conferring selectivity and enhancing crop safety and production

The sacred sound of kirtan: An ethno musicological – anthropological analysis of the Sikh community in Athens
Get PDFThis paper aims to explore the dynamic relationship between music and the sacred. In particular, it presents an ethno musicological – anthropological approach of the Sikh community in Tavros in Athens, Greece. Based on fieldwork research, I explore the ways in which the sacred music of kirtan is perceived and conceived by the members of the community. As fieldwork reveals, the migratory experience affects the musical performance of the sacred music. Despite these alterations, I argue that music in its ritual context empowers the sense of belonging of the community in the foreign place away from their motherland, India
On certain homological finiteness conditions
Get PDFIn this paper, we show that the injective dimension of all projective modules over a countable ring is bounded by the self-injective dimension of the ring. We also examine the extent to which the flat length of all injective modules is bounded by the flat length of an injective cogenerator. To that end, we study the relation between these finiteness conditions
on the ring and certain properties of the (strict) Mittag-Leffler modules. We also examine the relation between the self-injective dimension of the integral group ring of a group and Ikenaga’s generalized (co-)homological dimensio
