| Popis: | The study aims at discussing abiotic stress-related genes and metabolites in the crosstalking signal transduction pathways with emphasis to those in leaves of wild barley Hordeum spontaneum. Selected pathways involve tryptophan and target of rapamycin (or TOR) complex as core metabolites. In H. spontaneum, route towards tryptophan production seems to be mediated via anthranilate synthase acting as a master switch. Downstream auxin-related factors and proteins can secure plant’s ability to maintain proper growth rates and stress tolerance. Detected TOR in H. spontaneum participates in several signal transduction related pathways with a central role in nutrient starvation, ribosome biogenesis and protein synthesis and in standing oxidative and other abiotic stresses. TOR also participates as a master regulator of lifespan, aging and autophagy in H. spontaneum to regulate growth and maintain plant yield and its attributes under stress conditions. In conclusion, the present study emphasizes some mechanisms by which wild plant species, e.g., H. spontaneum, utilize to cope with abiotic stresses. |
