a b s t r a c tGrafting can enhance the tolerance of vegetable crops to soilborne diseases. The aim of this study was to investigate whether different tomato scionerootstock combinations may affect the plant susceptibility to Fusarium oxysporum f. sp. radicis-lycopersici (FORL), the causal agent of crown and root rot. A proteomic approach was used to investigate whenever the protein repertoire of the rootstock can be modified by FORL infection, in relation to cultivar susceptibility/tolerance to the disease. To this purpose, plants of tomato hybrids with different vigor, "Costoluto Genovese" (less vigorous) and "Kadima" (more vigorous), were grafted onto "Cuore di Bue" and "Natalia" hybrids, sensitive and tolerant versus FORL infections, respectively. Disease symptoms, plant biomasses, and protein expression patterns were evaluated 45 days after FORL inoculation. The extent of vascular discoloration caused by FORL in tomato plants grafted on "Natalia" rootstock (0.12e0.37 cm) was significantly lower than that of plants grafted on sensitive "Cuore di Bue" (1.75e6.50 cm). FORL symptoms significantly differed between "Costoluto Genovese" and "Kadima" scions only when grafted on sensitive rootstock. Shoot FW of non-inoculated "Kadima"/"Cuore di Bue" combination was 35% lower than "Kadima"/"Natalia", whereas no difference was manifested in inoculated plants. Shoot FW of inoculated "Costoluto Genovese"/"Cuore di Bue" combination was decreased of 39%, whereas that of "Costoluto Genovese"/"Natalia" of 11%, compared to control plants. Proteomic results showed a higher representation of proteins associated with pathogen infection in the tolerant rootstock, compared to the sensitive one, meaning a direct involvement of plant defence mechanisms in the tomato response to the pathogen challenge.

climate change is that most agricultural regions will experience additional extreme environmental fluctuations [2]. Direct injuries due to high temperatures include protein denaturation and aggregation and increased fluidity of membrane lipids. Indirect or slower heat injuries include inactivation of enzymes in chloroplast and mitochondria, inhibition of protein synthesis, protein degradation and loss of membrane integrity [3]. Heat stress also affects the organization of microtubules by splitting and/or elongation of spindles, formation of microtubule asters in mitotic cells and elongation of phragmoplast microtubules [4].The unfavourable effects of heat stress can be mitigated by developing crop plants with improved thermotolerance using an assortment of genetic approaches. For this reason, a thorough understanding of physiological responses of plants to high temperature, mechanisms of heat tolerance and possible strategies for improving crop thermotolerance is crucial. Acquiring thermotolerance is a lively progression by which considerable amounts of plant resources are diverted to structural and functional maintenance to escape damages caused by heat stress. Although biochemical and molecular aspects of thermotolerance in plants are relatively well understood, additional studies focused on phenotypic flexibility and assimilate partitioning under heat stress and factors modulating crop heat tolerance are imperative. High temperature during seed germination may slow down or totally inhibit germination, depending on plant species and the intensity of the stress [5]. At later stages, high IntroductionFuture global climate change, with predicted 1.5-5.8 °C increases in temperatures by 2100 has to cause heat stress to create threats to agricultural production [1]. An increase in global temperature ranging from 1.1 to 6.4 °C depending on global emissions scenarios, will accompany the rises in atmospheric CO 2 . Though high temperature and other abiotic stresses are clearly limiting factors for crops cultivated on marginal lands, crop productivity far and wide is often at the mercy of random environmental fluctuations. Existing assumption about global Heat Stress Responses and Thermotolerance AbstractThe rising ambient temperature by plant cells is crucial for the timely activation of various molecular defences before the appearance of heat damage. The heat-threshold level varies considerably at different developmental stages. With a view to survive under heat stress, mechanisms of regulation at the molecular level enable plants to prosper. Traditional breeding contributed for improving heat tolerance meagrely. The genetic transformation approach needs to be accelerated that can mitigate harmful effects by developing improved thermotolerance of crop plants. In this background, a thorough understanding of physiological responses of plants to high temperature, mechanisms of heat tolerance and possible strategies is vital. Temperature changes are sensed through cellular responses due to signal transduction into the c...

“…The aim of the molecular analyses is to facilitate selection of plants with higher adaptation to the conditions of water stress or to introduce new cultivars by using genetic engineering or traditional breeding techniques (Yokoi et al 2002;Tamura et al 2003;Rao et al 2006). The plants' acclimation is related to the changes in gene expression and composition of the proteome and metabolome (Kosová et al 2011;Swigonska and Weidner 2013). Proteome studies allow the examination of the actual products of gene expression and post-translational modifications of proteins in plants tissues (Jiang et al 2007).…”

Changes in the root proteome of Triticosecale grains germinating under osmotic stress

Osmotic stress causes many adverse symptoms in plants, which include, for example, growth limitation and decrease or even absence of yield. Proteomic analyses of plant responses to stressors could lead to the introduction of crops with high resistance to osmotic stress. Such plants would be characterized by high yield even under unfavorable environmental conditions. In this article we describe changes in the protein profiles occurring in response to mild and moderate osmotic stress in triticale roots. Analysis of the protein profiles of these roots showed an increased abundance of 14 and a decreased abundance of 11 proteins under mild osmotic stress conditions while a moderate osmotic stress caused an increased abundance of 18 and a decreased abundance of 33 proteins. Twenty-five proteins, whose quantity altered under stress were identified using MALDI-TOF mass spectrometry. The identified proteins were classified into the categories of proteins associated with: defense mechanisms, metabolism, transcription, cell structure, protein synthesis, transport and signal transduction. The functions of identified proteins were discussed in relation to osmotic stress. Some of the identified proteins may be responsible for the adaptation of plants to adverse conditions.
