“…Up-regulation of these genes, which are involved in the synthesis of raffinose-family oligosaccharides is consistent with the accumulation of raffinose, galactinol, and related compounds observed during seed filling and desiccation phases. These compounds serve as osmoprotectants and antioxidants in leaves and developing seeds [45,46,47,48]. …”

Soybean (Glycine max) seeds are an important source of seed storage compounds, including protein, oil, and sugar used for food, feed, chemical, and biofuel production. We assessed detailed temporal transcriptional and metabolic changes in developing soybean embryos to gain a systems biology view of developmental and metabolic changes and to identify potential targets for metabolic engineering. Two major developmental and metabolic transitions were captured enabling identification of potential metabolic engineering targets specific to seed filling and to desiccation. The first transition involved a switch between different types of metabolism in dividing and elongating cells. The second transition involved the onset of maturation and desiccation tolerance during seed filling and a switch from photoheterotrophic to heterotrophic metabolism. Clustering analyses of metabolite and transcript data revealed clusters of functionally related metabolites and transcripts active in these different developmental and metabolic programs. The gene clusters provide a resource to generate predictions about the associations and interactions of unknown regulators with their targets based on “guilt-by-association” relationships. The inferred regulators also represent potential targets for future metabolic engineering of relevant pathways and steps in central carbon and nitrogen metabolism in soybean embryos and drought and desiccation tolerance in plants.

“…Myo-inositol metabolic regulation appears to be a convergence point for abiotic and biotic stress responses. Myo-inositol is accumulating under most abiotic stress conditions and is positively contributing to tolerance as a compatible solute (Tan et al, 2013). A negative relationship between myo-inositol accumulation and pathogen resistance and PCD initiation was found in Arabidopsis , with a positive correlation between myo-inositol depletion and increased SA production and cell death (Chaouch and Noctor, 2010).…”

Plants growing in their natural habitats are often challenged simultaneously by multiple stress factors, both abiotic and biotic. Research has so far been limited to responses to individual stresses, and understanding of adaptation to combinatorial stress is limited, but indicative of non-additive interactions. Omics data analysis and functional characterization of individual genes has revealed a convergence of signaling pathways for abiotic and biotic stress adaptation. Taking into account that most data originate from imposition of individual stress factors, this review summarizes these findings in a physiological context, following the pathogenesis timeline and highlighting potential differential interactions occurring between abiotic and biotic stress signaling across the different cellular compartments and at the whole plant level. Potential effects of abiotic stress on resistance components such as extracellular receptor proteins, R-genes and systemic acquired resistance will be elaborated, as well as crosstalk at the levels of hormone, reactive oxygen species, and redox signaling. Breeding targets and strategies are proposed focusing on either manipulation and deployment of individual common regulators such as transcription factors or pyramiding of non- (negatively) interacting components such as R-genes with abiotic stress resistance genes. We propose that dissection of broad spectrum stress tolerance conferred by priming chemicals may provide an insight on stress cross regulation and additional candidate genes for improving crop performance under combined stress. Validation of the proposed strategies in lab and field experiments is a first step toward the goal of achieving tolerance to combinatorial stress in crops.

“…A second line of evidence links cold-evoked NO to the regulation of genes involved in the metabolism of compatible compounds, i.e. Pro and myo-inositol (Table 8.2) (Zhao et al 2009;Tan et al 2013). As mentioned earlier, Pro accumulates in acclimated plants via a NO-dependent mechanism.…”

“…(Zhang et al 2008), which suggests that the regulation of P5CS1 might constitute a pleiotropic mechanism controlled by NO signalling under stress conditions. A recent report on myo-inositol synthesis provides another example of a link between the synthesis of compatible solutes triggered by cold and the regulation of cold-responsive gene expression by NO (Tan et al 2013). Finally, it should be noted that genes related to NO metabolism are themselves up-regulated in response to low temperature.…”

Nitric Oxide Action in Abiotic Stress Responses in Plants

Low temperature constitutes a major constraint for plant development and spreading and imprints plant biodiversity. Plant tolerance towards cold is a complex matter that relies on deep metabolic reprogramming principally governed by transcriptomic changes themselves controlled through multiple signalling pathways. A set of recent reports points out nitric oxide (NO) as a key element of signalling networks underlying plant response to low temperature. Based on the identification of several cold-regulated NO-dependent genes, that play key functions during plant response to temperature lowering, NO might sustain major functions during cold stress. This chapter summarizes our current knowledge on NO availability and bioactivity during low-temperature response, with a special emphasis on its implication in the regulation of gene expression.
