Water deficit is a severe environmental stress and the major constraint on plant productivity with an evident effect on plant growth. The aim of this work was to study Triticum and Aegilops seedlings differing in their response to drought stress at the physiological and molecular levels. The identification of resistant and sensitive genotypes was firstly(More)
Artemisia annua L. is a herb traditionally used for treatment of fevers. The glandular trichomes of this plant accumulate, although at low levels, artemisinin, which is highly effective against malaria. Due to the great importance of this compound, many efforts have been made to improve knowledge on artemisinin production both in plants and in cell(More)
The ability to rapidly distinguish trichothecene chemotypes in a given species/population of the genus Fusarium is important due to significant differences in the toxicity of these secondary metabolites. A multiplex PCR assay, based on primer pairs derived from the Tri3, Tri5 and Tri7 genes of the trichothecene gene cluster was established for the(More)
Artemisinin is a sesquiterpene antimalarial compound produced, though at low levels (0.1–1% dry weight), in Artemisia annua in which it accumulates in the glandular trichomes of the plant. Due to its antimalarial properties and short supply, efforts are being made to improve our understanding of artemisinin biosynthesis and its production. Native(More)
BACKGROUND The molecular mechanisms altered by the traditional mutation and screening approach during the improvement of antibiotic-producing microorganisms are still poorly understood although this information is essential to design rational strategies for industrial strain improvement. In this study, we applied comparative genomics to identify all genetic(More)
Fusarium trichothecenes are a group of fungal toxic metabolites whose synthesis requires the action of gene products from three different genetic loci. We evaluated, both chemically and by PCR assays, 55 isolates of Fusarium culmorum from eight European countries and different host plants for their ability to produce trichothecenes. Specific sequences in(More)
Wheat bran is generally considered a byproduct of the flour milling industry, but it is a great source of fibers, minerals, and antioxidants that are important for human health. Phenolic acids are a specific class of wheat bran components that may act as antioxidants to prevent heart disease and to lower the incidence of colon cancer. Moreover, phenolic(More)
Betacyanin (betanin), total phenolics, vitamin C and antioxidant capacity (by Trolox-equivalent antioxidant capacity (TEAC) and oxygen radical absorbance capacity (ORAC) assays) were investigated in two differently colored cactus pear (Opuntia ficus-indica (L.) Mill.) genotypes, one with purple fruit and the other with orange fruit, from the Salento area,(More)
A pressing necessity of the Apulian wine industry is to be able to pilot and to control wine production to obtain wines with peculiar characteristics and with the typicality guaranteed by the denominations of origin. The employment of selected autochthonous yeast strains would be a potent instrument to improve the organoleptic and sensory characteristics of(More)
Suspension cell cultures of Helianthus annuus L. were previously established for the production of the most active component of vitamin E, alpha-tocopherol, by optimizing medium composition and culture conditions. In the present work, the possibility of enhancing alpha-tocopherol production by the addition of jasmonic acid to the culture medium was(More)
