Integrative analysis of transcriptome, microRNA-seq and metabolome reveals an essential role of exogenous melatonin in enhancing salt stress tolerance during seed germination in maize [miRNA-seq]

ABSTRACT: To investigate the role of melatonin in salt tolerance of maize, we determine the seed germinated rate of maize under CK, NaCl and NaCl+melatonin. We then performed miRNA profiling analysis using data obtained from miRNA-seq of the seeds of three different treatments.

Exogenous melatonin promotes rice seed germination under salinity through regulating reactive oxygen species and phytohormones

Project description:Melatonin plays a potential role in multiple plant developmental processes and stress response. However, there are no reports regarding exogenous melatonin promoting rice seed germination under salinity and nor about the underlying molecular mechanisms at genome-wide. Here, we revealed that exogenous application of melatonin conferred roles in promoting rice seed germination under salinity. The putative molecular mechanisms of exogenous melatonin in promoting rice seed germination under high salinity were further investigated through metabolomic and transcriptomic analyses. The results state clearly that the phytohormone contents were reprogrammed, the activities of SOD, CAT, POD were enhanced, and the total antioxidant capacity was activated under salinity by exogenous melatonin. Additionally, melatonin-pre-treated seeds exhibited higher concentrations of glycosides than non-treated seeds under salinity. Furthermore, exogenous melatonin alleviated the accumulation of fatty acids induced by salinity. Genome-wide transcriptomic profiling identified 7160 transcripts that were differentially expressed in NaCl, MT100 and control. Pathway and GO term enrichment analysis revealed that genes involved in the response to oxidative stress, hormone metabolism, heme building, mitochondrion, tricarboxylic acid transformation were altered after melatonin pre-treatment under salinity. This study provides the first evidence of the protective roles of exogenous melatonin in increasing rice seed germination under salt stress, mainly via activation of antioxidants and modulation of metabolic homeostasis.

Melatonin enhances plant growth and abiotic stress tolerance in soybean plants

Project description:Melatonin is a well-known agent that plays multiple roles in animals. Its possible function in plants is less clear. In the present study, we tested the effect of melatonin (N-acetyl-5-methoxytryptamine) on soybean growth and development. Both spraying of leaves and seed-coating with melatonin significantly promoted soybean growth as judged from leaf size and plant height. This enhancement was also observed in soybean production and their fatty acid content. Melatonin increased pod number, seed number and seed weight. However, the 100-seed weight was not influenced by melatonin application. Melatonin also improved soybean tolerance to salt and drought stresses. Transcriptome analysis revealed that melatonin up-regulated the expression of many genes and alleviated the inhibitory effects of salt stress on gene expressions. Further detailed analysis of the affected pathways documents that melatonin likely achieved its promotional roles in soybean through enhancement of genes involved in cell division, photosynthesis, carbohydrate metabolism, fatty acid biosynthesis and ascorbate metabolism. Our results demonstrate that melatonin has significant potential for improving of soybean growth and seed production. Further study should uncover more about the molecular mechanisms of melatoninM-bM-^@M-^Ys function in soybeans and other crops. Four different treatments were chosen, water, salt, 100M-BM-5M melatonin and salt plus 100M-BM-5M melatonin. The comparison of salt/melatonin-treated sample versus water-treated sample reveals salt or melatonin induced transcriptome changes. The comparison of melatonin plus salt treated sample versus salt-treated sample reveals melatonin induced changes when salt exists.

Melatonin affects endothelial cells-derived exosomal miRNA expression

Project description:The proper response to shear stress involves multiple cell components of the vascular wall including endothelial cells (ECs), smooth muscle cells (SMCs), and the intercellular communications between them. Mounting evidence indicates that retinoid acid receptor-related orphan receptor-α (RORα) mediates many biological activities of melatonin including transactivation of transcriptional factors, and anti-inflammation. In this study we investigated the effect of melatonin on endothelial cells-derived exosomal miRNA expression. We used microarrays to detail the global program of gene expression underlying melatonin treatment and identified distinct classes of dys-regulated genes during this process.

Expression profile of Maize (Zea mays L.) Embryonic Axes During Germination: Regulation of Ribosomal Protein mRNAs.

Project description:Seed germination is a critical developmental process in plant propagation. Knowledge of the gene expression patterns in this critical process is important in order to understand the main biochemical reactions involved in successful germination, specially for economically relevant plants such as Maize. The purpose of this study is the gene expression analysis of quiescent and germinated maize embryonic axes to determine the regulatory mechanism for (r)-protein expression during the maize development process.

Arabidopsis germination and two week growth on ionic vs osmotic stress

Project description:Arabidopsis Col-0 seeds were germinated and grown for two weeks on Arabidopsis thaliana salt media (ATS, control) or ATS media supplemented 50, 75, 100 or 125 mM NaCl that imposes both an ionic and osmotic stress; or ATS media supplemented with iso-osmolar concentrations of sorbitol (100, 150, 200 or 250 mM) that imposes only an osmotic stress. The aim of the study was to identify genes involved in plant growth and adaptation to ionic stress compared to genes involved in growth and adaptation to osmotic stress conditions. To do this we identified lists of genes that are differentially expressed in plants grown in NaCl (A) and lists of genes differentially expressed in plants grown in sorbitol (B). We then compared these lists to find ionic/salt-specific genes that are only expressed in plants grown in NaCl and not in plants grown in sorbitol; and osmotic genes that are expressed both in plants grown in NaCl and in plants grown in sorbitol.
