Abstract
The 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.
