The present scenario sounds an alarm over the increasing global mean temperature that is coupled with reduced water availability. review highlights osmotic changes occur on account of deficit under drought and salinity. Reduced potential ameliorates tension in xylem tissue, thus ultimately leading to cavitation embolism. sustained leads production increased reactive oxygen species (ROS) not comprehended by usual antioxidative defense system. upregulation system, variation root architecture, presence trichomes, stomatal regulation alleviate overall use efficiency (WUE) saline conditions. These mitigation strategies are expression dehydrins salt overly sensitive genes (SOS) salinity, respectively, at molecular level provide resistance against same.

In-depth multi-omics approaches have evolved to integrate cellular processes at various levels into a systems biology knowledge base. Metabolomics plays crucial role molecular networking bridge gaps between genotypes and phenotypes. However, greater complexity of metabolites diverse chemical physical properties has limited advances plant metabolomics. For several years, applications liquid/gas chromatography (LC/GC)-mass spectrometry (MS) nuclear magnetic resonance (NMR) been constantly developed. Recently, ion mobility (IMS)-MS shown utility resolving isomeric isobaric metabolites. Both MS NMR combined metabolomics significantly increased identification quantification an untargeted targeted manner.
