Relevance of Proteomic Investigations in Plant Abiotic Stress Physiology

Abstract: Plant growth and productivity are influenced by various abiotic stresses. Stressful conditions may lead to delays in seed germination, reduced seedling growth, and decreased crop yields. Plants respond to environmental stresses via differential expression of a subset of genes, which results in changes in omic compositions, such as transcriptome, proteome, and metabolome. Since the development of modern biotechnology, various research projects have been carried out to understand the approaches that plants have … Show more

“…Moreover, mRNA availability can be affected by post-transcriptional processes at the stage of RNA maturation, splicing, transportation or translation initiation as well as degradation (40). Therefore, the mRNA levels in a particular biological sample cannot always be used to predict changes in protein expression (30,41). In addition, protein expression is also regulated at the posttranslational level via glycosylation, phosphorylation, phosphorylation, sumoylation or ubiquitination (42,43).…”

“…A number of abiotic stresses like drought, temperature, and salinity, usually reduce crop yield [1]. It has been approximated that crops reachonly 25% of their likely yield, because of the damaging effects of environmental stresses [2].…”

“…2D-PAGE gels also offer information on various biochemical and biophysical parameters including isoelectric point, molecular weight, and posttranslational modifi cations (PTMs) (Gorg et al 2004 ;WittmannLiebold et al 2006 ). 2D-PAGE is a reproducible, sensitive, and steadfast technique for studying comparative alterations in proteome of an organism (Somiari et al 2003 ;Hakeem et al 2012 ).…”
