Pre-invasion history and demography shape the genetic variation in the insecticide resistance-related acetylcholinesterase 2 gene in the invasive Col…

2012

Abstract Background Invasive pest species offers a unique opportunity to study the effects of genetic architecture, demography and selection on patterns of genetic variability. Invasive Colorado potato beetle (Leptinotarsa decemlineata) populations have experienced a rapid range expansion and intense selection by insecticides. By comparing native and invasive beetle populations, we studied the origins of organophosphate (OP) resistance-associated mutations in the acetylcholinesterase 2 (AChE2) gene, and the role of selection and demography on its genetic variability. Results Analysis of three Mexican, two US and five European populations yielded a total of 49 haplotypes. Contrary to the exp…

trans -Lycopene from tomato juice attenuates inflammatory biomarkers in human plasma samples: An intervention trial

2017

cope : To evaluate the effects of carotenoids from tomato juice (TJ) on inflammatory biomarkers, by performing a 4-week dose-response nutritional trial in a population at high cardiovascular risk. Methods and results : An open, prospective, randomized, cross-over, and controlledclinical trial was carried out with 28 volunteers (mean age 69.7 ± 3.1 years; mean BMI 31.5 ± 3.6 kg/m2) at high cardiovascular risk, which were assigned to consume daily for 4 weeks in random order: 200 mL (LD) or 400 mL (HD) of TJ, or water as a control (C), with a 21-day wash-out period between each intervention. Blood samples were collected at baseline (B) and after each intervention. Endpoints included significa…

Grafting Eggplant Onto Underutilized Solanum Species and Biostimulatory Action of Azospirillum brasilense Modulate Growth, Yield, NUE and Nutritional…

2022

The grafting of vegetable crops is considered a valuable mean for ensuring the yield and quality under different cultivation conditions. Simultaneously, there are increasing research efforts in exploiting underutilised plants as potential rootstocks for vegetables to increase the sustainability of horticultural systems. In accordance with the European Green Deal, the application of biostimulants is a fashionable and ecological agronomic practice to enhance the production and quality of vegetables. Thus, the current research appraised the synergistic effect of grafting eggplant onto various allied potential rootstocks (Solanum torvum, S. aethiopicum and S. macrocarpon) and of applying a plan…

The sequencing of the complete genome of a Tomato black ring virus (TBRV) and of the RNA2 of three Grapevine chrome mosaic virus (GCMV) isolates from…

2014

The complete genome of a Tomato black ring virus isolate (TBRV-Mirs) (RNA1, 7,366 nt and RNA2, 4,640 nt) and the RNA2 sequences (4,437; 4,445; and 4,442 nts) of three Grapevine chrome mosaic virus isolates (GCMV-H6, -H15, and -H27) were determined. All RNAs contained a single open reading frame encoding polyproteins of 254 kDa (p1) and 149 kDa (p2) for TBRV-Mirs RNA1 and RNA2, respectively, and 146 kDa for GCMV RNA2. p1 of TBRV-Mirs showed the highest identity with TBRV-MJ (94 %), Beet ringspot virus (BRSV, 82 %), and Grapevine Anatolian ringspot virus (GARSV, 66 %), while p2 showed the highest identity with TBRV isolates MJ (89 %) and ED (85 %), followed by BRSV (65 %), GCMV (58 %), and GA…

The behavioral responses of the egg parasitoid Ooencyrtus telenomicida to semiochemicals from first and second trophic level

2009

In this study the responses of females of the egg parasitoid Ooencyrtus telenomicida (Vassiliev) (Hymenoptera: Encyrtidae) to volatile and contact chemicals from its host Nezara viridula (L.) (Heteroptera: Pentatomidae) and from host plant Solanum lycopersicum L. were investigated in a Y-tube olfactometer and in open arena. Our results in the Y-tube olfactometer tests showed that: (1) female wasps were attracted to volatiles from adult host virgin male and to volatiles from a host mated female, showing a clear preference for the volatiles emitted from the former; volatiles from host virgin females did not attract O. telenomicida females; (2) only volatiles produced by host-damaged plant com…

NECREMNUS ARTYNES (WALKER) PARASSITOIDE DI TUTA ABSOLUTA (MEYRICK) SU POMODORO, MELANZANA E SOLANUM NIGRUM L. IN SERRA A CONDUZIONE BIOLOGICA

2011

Nel 2010, in serre del palermitano gestite secondo i canoni dell'agricoltura biologica, è stato condotto uno studio volto all'individuazione degli antagonisti naturali indigeni del lepidottero gelechide Tuta absoluta, fitofago esotico dannoso alle solanacee recentemente introdotto in Italia. Le piante campionate sono state il pomodoro, da gennaio a giugno, la melanzana, da fine marzo a giugno, e Solanum nigrum che cresceva spontaneamente all'interno delle serre in piccoli spazi liberi dalle solanacee coltivate. Per tenere sotto controllo il gelechide, il serricoltore ha effettuato tre trattamenti con Bacillus thuringiensis da metà marzo a fine aprile. Oltre al predatore Nesidiocoris tenuis,…

Grafting suitability of Sicilian eggplant ecotypes onto Solanum torvum: Fruit composition, production and phenology

2013

The eggplant (Solanum melongena L.) is one of the most widely cultivated crops in tropical and temperate regions around the world and is suitable for propagation through grafting. In many parts of the world, grafting is a routine technique used in continuous cropping systems, because in the horticulture field is a sustainable technique that allows cultivators to overcome abiotic or biotic stress. The objective of this research was to evaluate the suitability at the grafting of four Sicilian eggplant ecotypes grown in open field in Sicily, Italy. Vegetables in general are a great source of minerals in the human diet and the eggplant (Solanum melongena L.) provides significant quantities of v…

Involvement of nitrate reductase and pyoverdine in competitiveness of Pseudomonas fluorescens strain C7R12 in soil

2001

ABSTRACT Involvement of nitrate reductase and pyoverdine in the competitiveness of the biocontrol strain Pseudomonas fluorescens C7R12 was determined, under gnotobiotic conditions, in two soil compartments (bulk and rhizosphere soil), with the soil being kept at two different values of matric potential (−1 and −10 kPa). Three mutants affected in the synthesis of either the nitrate reductase (Nar − ), the pyoverdine (Pvd − ), or both (Nar − Pvd − ) were used. The Nar − and Nar − Pvd − mutants were obtained by site-directed mutagenesis of the wild-type strain and of the Pvd − mutant, respectively. The selective advantage given by nitrate reductase and pyoverdine to the wild-type strain was as…
