Genetic transformation of an elite white poplar genotype (Populus alba L., cv. ‘Villafranca’) was performed with MAT vectors carrying the ipt and rol genes from Agrobacterium spp. as morphological markers. The effects associated with the use of different gene promoters and distinct in vitro regeneration protocols were evaluated. Poplar plantlets showing(More)
The ω-3 fatty acid desaturases (FADs) are enzymes responsible for catalyzing the conversion of linoleic acid to α-linolenic acid localized in the plastid or in the endoplasmic reticulum. In this research we report the genotypic and phenotypic variation of Italian Olea europaea L. germoplasm for the fatty acid composition. The phenotypic oil characterization(More)
The development of an efficient and accurate method for extra-virgin olive oils cultivar and origin authentication is complicated by the broad range of variables (e.g., multiplicity of varieties, pedo-climatic aspects, production and storage conditions) influencing their properties. In this study, artificial neural networks (ANNs) were applied on several(More)
Organic farming prohibits the use of genetically modified organisms (GMOs) inasmuch as their genetic material has been altered in a way that does not occur naturally. In actual fact, there is a conventional identity between GMOs and transgenic organisms, so that genetic modification methods such as somatic hybridization and mutagenesis are equalized to(More)
The aim of this study was to investigate the culturable bacteria living in soil cultivated with Basta-tolerant transgenic white poplars (Populus alba L. 'Villafranca'). Plate Count Agar medium containing phosphinothricin, the active component of Basta, was used to isolate the herbicide-resistant bacteria (HRB). No significant changes in the size of the soil(More)
The advent of modern molecular biology and recombinant DNA technology has resulted in a dramatic increase in the number of insect-resistant (IR) and herbicide-tolerant (HT) plant varieties, with great economic benefits for farmers. Nevertheless, the high selection pressure generated by control strategies for weed and insect populations has led to the(More)
Olea europaea L. ssp. sativa is an evergreen fruit tree well adapted to the climate conditions of the Mediterranean basin. Its cultivation in northern regions may expose the plants to cold and frost damages during winter, although the maturation of olive fruit in cool environments may provide olive oil with peculiar qualitative characteristics.
