Salinity acclimation ameliorates salt stress in tomato (Solanum lycopersicum L.) seedlings by triggering a cascade of physiological processes in the leaves

AbstractThe signalling molecules serve as a fundamental requirement in plants and respond to various internal and external cues. Among several signalling molecules, the significance of gasotransmitters has been realized in several plant developmental and environmental constraints. The hydrogen sulfide (H2S) is a novel signalling molecule in higher plants and is involved in several physiological processes right from seed germination to flowering and fruit ripening. Moreover, H2S also assist plants in managing biotic and abiotic stresses, therefore serves as one of the imperative choice of chemical priming. Yet, the metabolism of H2S is not much explored and only appraisal study is made till date from Arabidopsis thaliana. Therefore, the present investigation explored the elucidation of H2S metabolism in crop plant Solanum lycopersicum L. Through in silico investigations the study demonstrated the participation of 29 proteins involved in H2S metabolism, which are mainly localized in cytosol, chloroplast, and mitochondria. Additionally, the relevant protein-protein interactomes were also inferred for sub-cellular compartments and expression data were explored under development and biotic stresses namely PAMPs treatment and bacterial infection. The information generated here will be of high relevance to better target the H2S metabolism to enhance the tomato prospects and also serve a preliminary investigation to be adopted in other agronomic important crops.

Zone Temperature

In order to study the impact of salt stress (0, 1.5, 3 and 6) ds.m-1 in nutrient’s solution on tomato plant (Solanum lycopersicum L. cv. memory) at different root zone temperature [low (20°C), medium (25°C) and high (30°C)], an experiment was carried at Department of Horticultural, Ferdowsi University of Mashhad, Islamic Republic of Iran. The result showed that low and high root zone heating decreased leaf area, total sugar and phenol content compared to root zone temperature 25°C (optimum), while main branches number, pH, E.C. and anthocyanin of fruit ,increased at high root zone temperature compared to low root zone temperature. Flavonoid increased under the root zone temperature of 20°C in comparison with temperatures 25 and 30°C, and stem diameter was not affected by root zone heating. Furthermore, salt stress at the level of 3 ds.m-1 increased stem diameter, total sugar, pH and EC of fruit, leaf area and phenol content, whereas salt stress at a high level (6 ds.m-1) increased flavonoid content. Besides, anthocyanin content decreased in control and salt stress at 6 ds.m-1 when compared to salt stress at 3 ds.m-1.
