Calcium signalling involves combining different calcium signatures with various calcium sensors that differ by their expression, subcellular localisation, sensitivity to calcium, and multiples target proteins. The complexity of calcium signalling is also illustrated by the interactions between Ca²⁺-dependent pathways and Ca²⁺-independent channels. These calcium sensor proteins can recognise calcium modulations and translate them into a biochemical response.

Salt-tolerant plants (halophytes) are precious bioresources in the context of the current global climate changes. Multidisciplinary approaches are necessary to understand their adaptive strategies and hence their ecosystem functioning. Combining studies at the protein and the ecophysiology levels provide reliable insights explaining the performance of these species.

High temperature stress in wheat (Triticum aestivum L.) causes significant yield reduction. Identification of traits and genotypes is necessary for wheat yield improvement under temperature stress. In the present study, a strong correlation was observed between higher pollen viability and higher grain yield under heat stress and contrast genotypes were identified for pollen viability. The identified trait and genotypes can be efficiently used for improving temperature stress tolerance in wheat breeding programme.

Plant adaptation to environmental stress requires the expression of specific stress-related genes and metabolites. These molecular networks are complex, and while much has been discovered in this field, some aspects remain unknown and must be explained. Expression analysis of photoreceptors genes in tomato under cold stress as function of blue light condition revealed difference in the transcript levels (up regulated), especially Cry2 and PhyB. Further research could determine the exact mechanism of cold stress tolerance in tomato (Solanum lycopersicum L.).
