Proteomics

10.0K
A proteome is the entire set of proteins that a cell type produces. We can study proteomes using the knowledge of genomes because genes code for mRNAs, and the mRNAs encode proteins. Although mRNA analysis is a step in the right direction, not all mRNAs are translated into proteins.
Proteomics is the study of proteomes' function. It involves the large-scale systematic study of the proteome to denote the protein complement expressed by a genome. Scientist Mark Wilkins coined the term...

Area of Science:

  • Plant biology and molecular genetics
  • Biochemistry and crop science

Background:

  • Abiotic stresses (salinity, drought, heat) significantly limit crop growth and productivity.
  • Plant responses to abiotic stress are complex, involving dynamic molecular and biochemical processes.
  • Protein phosphorylation, mediated by protein kinase cascades, is a common biochemical indicator across various abiotic stresses.

Purpose of the Study:

  • To review recent developments in understanding plant phosphoproteome changes induced by abiotic stresses.
  • To discuss advancements in phosphoproteomics tools and databases for abiotic stress research.
  • To critically assess the potential of targeting phosphoproteins for crop improvement and enhancing stress tolerance.

Main Methods:

  • Literature review of studies on abiotic stress-induced transcriptome, proteome, and phosphoproteome changes in plants.
  • Analysis of biochemical and computational tools used for identifying and characterizing phosphoproteins.
  • Examination of existing phosphoproteomics repositories and databases.

Main Results:

  • Numerous phosphoproteins involved in plant abiotic stress responses have been identified and characterized.
  • There is a growing number of phosphoproteomics databases and repositories available.
