Saponins, a group of glycosidic compounds present in several plant species, have aglycone moieties that are formed using triterpenoid or steroidal skeletons. In spite their importance as antimicrobial and possible benefits for human health, knowledge the genetic control saponin biosynthesis is still poorly understood. Medicago genus, hemolytic activity saponins related to nature moieties. We identified cytochrome P450 gene (CYP716A12) involved synthesis truncatula combined biochemical...
Olive (Olea europaea L.) fruits contain numerous secondary metabolites, primarily phenolics, terpenes and sterols, some of which are particularly interesting for their nutraceutical properties. This study will attempt to provide further insight into the profile olive phenolic compounds during fruit development identify major genetic determinants metabolism.The concentration compounds, such as oleuropein, demethyloleuropein, 3-4 DHPEA-EDA, ligstroside, tyrosol, hydroxytyrosol, verbascoside...
Background and Aims Postveraison limitation of canopy photosynthesis delays grape berry ripening reduces sugar accumulation, thus lowering the alcohol content subsequent wines. This study was designed to evaluate whether similar results could be obtained by defoliation apical bunch zone using a leaf-plucking machine when approximately 16–17°Brix. Methods Results In 2011 2012, treatments were applied postveraison cv. Sangiovese vines (D) on either side each row mechanical leaf...
The secoiridoids are the main class of specialized metabolites present in olive (Olea europaea L.) fruit. In particular, secoiridoid oleuropein strongly influences oil quality because its bitterness, which is a desirable trait. addition, possesses wide range pharmacological properties, including antioxidant, anti-inflammatory, and anti-cancer activities. accordance, obtaining high varieties goal molecular breeding programs. Here we use transcriptomic approach to identify candidate genes...
The effectiveness of a postveraison application the film-forming antitranspirant Vapor Gard (VG, a.i. di-1-<i>p</i>-menthene) was investigated as technique to delay grape ripening and reduce sugar accumulation in berry. study carried out over 2010–2011 seasons nonirrigated vineyard cv. Sangiovese central Italy. applied at 2% concentration upper two-thirds canopy (most functional leaves) it significantly lowered leaf assimilation transpiration rates increased intrinsic water use efficiency....
Medicago truncatula is a model species for legumes. Its functional genomics have been considerably boosted in recent years due to initiatives based both Europe and US. Collections of mutants are becoming increasingly available this will help unravel the genetic control important traits many Our report on production three complementary mutant collections produced Italy frame national genomic initiative. Well established strategies were used: Tnt1 mutagenesis, TILLING activation tagging. Both...
Aiding optimal plant–environment interaction would favor plant resilience against environmental constrains including salt stress. We test the hypothesis that 6-Benzylaminopurine (BAP) primes grapevine's tolerance in vines (Vitis vinifera) received water (NaCl 100 mM) through modulation of gene expression BAP (AHK4, AHP1) and salt-stress (CAT, APX) inducible genes morpho-physiological traits. A subgroup had previously (48 h) been primed with (80 mg/L) before The expressions were 30% (CAT) 56%...
Taraxacum kok-saghyz R. (Tks) is a promising alternative species to Hevea brasiliensis for production of high quality natural rubber (NR). A comparative transcriptome analysis plants with differential NR will contribute elucidate which genes are involved in the synthesis, regulation and accumulation this polymer could help develop Tks into crop.We measured content latex 90 individual from 9 accessions, observing degree variability. We carried out de novo root sequencing, assembly, annotation...
In the last years greenhouse effect has been significantly intensified due to human activities, generating large additional amounts of Greenhouse gases (GHG). The fossil fuels are main causes that. Consequently, attention on composition national fuel mix grown, and renewables becoming a more significant component. this context, biomass is one most important sources renewable energy with great potential for production energy. study evaluated, through an LCA (Life Cycle Assessment) study,...
Taraxacum kok-saghyz (Tks), also known as the Russian dandelion, is a recognized alternative source of natural rubber quite comparable, for quality and use, to one obtained from so-called tree, Hevea brasiliensis. In addition that, Tks roots produce several other compounds, including inulin, whose use in pharmaceutical dietary products extensive. Histone-modifying genes (HMGs) catalyze series post-translational modifications that affect chromatin organization conformation, which, turn,...
Histone methylation and acetylation are key processes in the epigenetic regulation of plant growth, development, responses to environmental stimuli. The genes encoding for enzymes that responsible these chromatin post-translational modifications, referred as histone modification (HMGs), have been poorly investigated Leguminosae species, despite their importance establishment activity nitrogen-fixing nodules. In silico analysis Medicago truncatula HMGs identified 81 methyltransferases, 46...
Flavonoids are essential compounds widespread in plants and exert many functions such as defence, definition of organ colour protection against stresses. In Medicago truncatula, flavonoid biosynthesis accumulation is finely regulated terms tissue specificity induction by external factors, cold other Among flavonoids, anthocyanin precursors synthesised the cytoplasm, transported to tonoplast, then imported into vacuole for further modifications storage. present work, we functionally...
Three clones containing satellite DNA sequences were selected from a randomly sheared genomic library of Picea abies (clones PAF1, PAG004P22F (2F), and PAG004E03C (3C)). PAF1 contained 7 repeats that 37–55 bp in length had 68.9%–91.9% nucleotide sequence similarity. Two 2F 305–306 83% 3C 193–226 similarity 78.6%. The copy number per 1C 2F, was 2.7 × 10 6 , 2.9 5 4 respectively. In situ hybridization showed centromeric localization these two chromosome pairs with all but one three 3C....
We have established mutant collections of the model species Medicago truncatula according to current protocols. In particular, we used a transposon ( Tnt1 ) tagging method and an ethyl methanesulfonate (EMS) mutagenesis approach (TILLING). The were subjected both forward reverse genetics screenings, several mutants isolated that affect plant traits (e.g. shoot, root developments, flower morphology, etc.) also biosynthetic pathways secondary compounds (saponins tannins). Genes responsible for...
Double ‘free-hybrids’ (DH) in alfalfa were obtained by crossing a diallelic scheme, six multiplied simple hybrids (SH) derived from four partly inbred (S 2 ) lines. Analysis of the specific combining ability demonstrated that main source variation was for dry matter yield (DMY) DHs and supported heterosis values versus best parent an average +45% (ranging +5 to +76%). Investigation at molecular level carried out analysis sequence repeat markers on parental SHs 15 DH progenies comparison gene...
SummaryDuring an ongoing effort to recover and preserve local germplasm, 14 accessions of indigenous minor grapevine (Vitis vinifera L.) cultivars from the Umbria Region, Central Italy, were chosen because they had been neglected threatened with extinction. Their phenotypic genetic characteristics evaluated through ampelographic study their shoots, mature leaves, bunches, berries by genomic analysis using international set nine microsatellite (simple sequence repeat; SSR) markers (VVS2,...
