ABSTRACT

Proteomics is one of the most advanced molecular techniques for investi

gating protein profiles in stressed plants. Plants respond to stress by modi

fying their protein, either by up or downregulating their existing protein pool

or by synthesizing new proteins. The majority of the proteins were associ

ated with the antioxidative defense mechanism of the plants. In recent years,

proteomics has provided scientists with the tremendous ability to examine

protein profiles in stressed plants as it correlates the probable link between

protein abundance and plant stress tolerance. To get a better knowledge of

abiotic stress sensing and intracellular stress signal transduction pathways in

subcellular organelles could provide much more detailed information about

the fundamental mechanism of stress responses. In this chapter, we reviewed

all major contributions related to improved protein extraction protocols,

abiotic stress inducers, and their sequels on organelle proteomes to under

stand the protein level involvement of abiotic stress tolerance mechanism in

plants.
