    ABSTRACT: Chromium (Cr) is very toxic to both human beings and plants. This investigation aimed at understanding the physiological and molecular responses of rice seedlings to Cr stress. Cr toxicity did not significantly affect the morphological features and Cr accumulation in roots and shoots in Pokkali but not in BRRI 51 though reduction of chlorophyll concentration was noticed in leaves of both genotypes. These imply that Pokkali genotype does have mechanisms to cope with the Cr supplementation. Keeping this in mind, we performed quantitative real-time PCR analysis on the expression pattern of two chelators, OsPCS1 and OsMT1, which showed no significant changes in expression in roots and shoots of both Pokkali and BRRI 51 due to Cr stress. It suggests that the well-known strategy of metal sequestration under heavy metal stress is not active in roots of these particular genotypes. Moreover, expression of two heavy metal transporters, OsHMA3 and OsNRAMP1 was also not induced due to Cr stress in roots and shoots, suggesting that these transporters genes are not induced by Cr stress or may not be involved with Cr uptake in rice. We also performed a targeted study on the effect of Cr on Fe uptake mechanisms. Our studies showed consistent reduction in Fe uptake, Fe reductase activity and expression of Fe related genes (OsFRO1 and OsIRT1) under Cr stress in both roots and leaves of Pokkali. In contrast, these parameters and genes were significantly increased in Cr-sensitive BRRI 51 under Cr stress. These results confirm that limiting Fe uptake through the downregulation of Fe reductase and Fe transporter genes is the main strategy that Cr-tolerant Pokkali follow to cope with the Cr stress. Finally, increased CAT, POD and GR activity along with elevated glutathione and proline synthesis may provide strong antioxidant defense under Cr stress in Pokkali. Taken together, our findings reveal that Cr stress tolerance in rice (Pokkali) is not involved with metal sequestration but associated with reduced Fe transport and increased antioxidant defense.

    ABSTRACT: The germination ecology of Sideritis serrata was investigated in order to improve ex-situ propagation techniques and management of their habitat. Specifically, we analysed: (i) influence of temperature, light conditions and seed age on germination patterns; (ii) phenology of germination; (iii) germinative response of buried seeds to seasonal temperature changes; (iv) temperature requirements for induction and breaking of secondary dormancy; (v) ability to form persistent soil seed banks; and (vi) seed bank dynamics. Freshly matured seeds showed conditional physiological dormancy, germinating at low and cool temperatures but not at high ones (28/14 and 32/18 °C). Germination ability increased with time of dry storage, suggesting the existence of non-deep physiological dormancy. Under unheated shade-house conditions, germination was concentrated in the first autumn. S. serrata seeds buried and exposed to natural seasonal temperature variations in the shade-house, exhibited an annual conditional dormancy/non-dormancy cycle, coming out of conditional dormancy in summer and re-entering it in winter. Non-dormant seeds were clearly induced into dormancy when stratified at 5 or 15/4 °C for 8 weeks. Dormant seeds, stratified at 28/14 or 32/18 °C for 16 weeks, became non-dormant if they were subsequently incubated over a temperature range from 15/4 to 32/18 °C. S. serrata is able to form small persistent soil seed banks. The maximum seed life span in the soil was 4 years, decreasing with burial depth. This is the second report of an annual conditional dormancy/non-dormancy cycle in seeds of shrub species. This article is protected by copyright. All rights reserved.

    ABSTRACT: Trehalose and the trehalose biosynthetic pathway are important contributors and regulators of stress responses in plants. Among recent findings for trehalose and its metabolism, the role of signalling in the regulation of growth and development and its potential for use as a storage energy source can be listed. The xerophytic plant Capparis ovata (caper) is well adapted to drought and high temperature stress in arid and semi-arid regions of the Mediterranean. The contribution of trehalose and the trehalose biosynthetic pathway to drought stress responses and tolerance in C. ovata are not known. We investigated the effects of PEG-mediated drought stress in caper plants and analysed physiological parameters and trehalose biosynthetic pathway components, trehalose-6-phosphate synthase (TPS), trehalose-6-phosphate phosphatase (TPP), trehalase activity, trehalose and proline content in drought stress-treated and untreated plants. Our results indicated that trehalose and the trehalose biosynthetic pathway contributed to drought stress tolerance of C. ovata. Overall growth and leaf water status were not dramatically affected by drought, as both high relative growth rate and relative water content were recorded even after 14 days of drought stress. Trehalose accumulation increased in parallel to induced TPS and TPP activities and decreased trehalase activity in caper plants on day 14. Constitutive trehalose levels were 28.75 to 74.75 μg·g·FW−1, and drought stress significantly induced trehalose accumulation (385.25 μg·g·FW−1 on day 14) in leaves of caper. On day 14 of drought, proline levels were lower than on day 7. Under drought stress the discrepancy between trehalose and proline accumulation trends might result from the mode of action of these osmoprotectant molecules in C. ovata.

    ABSTRACT: Measuring biomarkers from plant tissue samples is challenging and expensive when the desire is to integrate transcriptomics, fluxomics, metabolomics, lipidomics, proteomics, physiomics and phenomics. We present a computational biology method where only the transcriptome needs to be measured and is used to derive a set of parameters for deterministic kinetic models of metabolic pathways. The technology is called Transcriptome-To-Metabolome™ (TTM™ ) biosimulations, currently under commercial development, but available for non-commercial use by researchers. The simulated results on metabolites of 30 primary and secondary metabolic pathways in rice (Oryza sativa) were used as the biomarkers to predict whether the transcriptome was from a plant that had been under drought conditions. The rice transcriptomes were accessed from public archives and each individual plant was simulated. This unique quality of the TTM™ technology allows standard analyses on biomarker assessments, i.e. sensitivity, specificity, positive and negative predictive values, accuracy, receiver operator characteristics (ROC) curve and area under the ROC curve (AUC). Two validation methods were also used, the holdout and 10-fold cross validations. Initially 17 metabolites were identified as candidate biomarkers based on either statistical significance on binary phenotype when compared with control samples or recognition from the literature. The top three biomarkers based on AUC were gibberellic acid 12 (0.89), trehalose (0.80) and sn1-palmitate-sn2-oleic-phosphatidylglycerol (0.70). Neither heat map analyses of transcriptomes nor all 300 metabolites clustered the stressed and control groups effectively. The TTM™ technology allows the emergent properties of the integrated system to generate unique and useful 'Omics' information.
