Tomato is a high value crop and the primary model for fleshy fruit development ripening. Breeding priorities include increased quality, shelf life tolerance to stresses. To contribute towards this goal, we re-sequenced genomes of Corbarino (COR) Lucariello (LUC) landraces, which both possess traits plant adaptation water deficit, prolonged shelf-life good quality. Through newly developed pipeline Reconstructor, generated genome sequences COR LUC using datasets 65.8 M 56.4 30-150 bp...
Despite intense research towards the understanding of abiotic stress adaptation in tomato, physiological adjustments and transcriptome modulation induced by combined salt low nitrate (low N) conditions remain largely unknown. Here, three traditional tomato genotypes were grown under long-term single stresses throughout a complete growth cycle. Physiological, molecular, measurements showed extensive morphophysiological modifications compared to control, conditions, resulting highest penalty...
Osmotin gene expression and protein synthesis were up‐regulated in young tomato ( Lycopersicon esculentum cv. Rheinlands Ruhm) plants after a short exposure (24 h) to 150 m M NaCl or 100 μ abscisic acid (ABA) dehydration 80% of original plant fresh weight. Osmotically induced accumulation osmotin mRNA was accompanied by large increase endogenous ABA levels. Increasing also observed during longer (7 days) salt. Upon treatment with NaCl. levels increased both root leaf tissues. an additional...
Improving crop adaptation to reduced agricultural inputs is a fundamental goal of current and future cropping systems, which must cope with resource scarcity feed an increasing world population. Landraces wild species showing tolerance traits are important source underexploited genetic that may contribute pursue this goal. In work, we exposed tomato lines different origin nitrogen water deficiency identify stress traits. Out 10 accessions, identified two genotypes, T292 T150, remarkable...
Plant productivity is severely affected by unfavourable environmental conditions (biotic and abiotic stresses). Among others, water deficit the plant stress condition which mostly limits quality quantity of products. Tolerance to a polygenic trait strictly dependent on coordinated expression large set genes coding for proteins directly involved in stress-induced protection/repair mechanisms (dehydrins, chaperonins, enzymes synthesis osmoprotectants detoxifying compounds, others) as well...

Corbarino (COR) and Lucariello (LUC) belong to the family of Mediterranean long shelf-life tomato landraces, producing high quality fruits under low water input cultivation regime in their traditional area. Understanding morpho-physiological molecular details peculiar drought stress tolerance these two genotypes may be key valorization as breeding material. Here, we show that open field, contrast with Red Setter variety (RED), yield COR LUC was similar irrigated or rainfed conditions a...
Pollution by Heavy Metals (HMs) represents one of the most important threatens for crops. Among HMS, Nickel (Ni++) represent a dangerous element, strictly linked to anthropic activity, which is easily accumulated in plants. In this study, effects Ni++ stress were investigated barley (Hordeum vulgare L. cv. Nure) grown hydroponically and exposed 1 mM up seven days. Ni++accumulated mainly roots, where 70-fold increase IRT1 transporter, involved Ni uptake was observed together with 17-fold...
Abstract Most of the crops are extremely susceptible to environmental stresses, because they have been selected for a high yield performance under optimal growth conditions. Not tolerant plants (glycophytes) respond changes in environment with complex mechanisms, involving network genes, which either up- or down-regulated. Some genes induced common between glycophytes and typically plants, e.g. xerophytes halophytes, supporting contention that stress tolerance mechanisms ubiquitous. In this...
