Proteomics is important in the systems biology approach because proteins perform biological functions. Resolution and identification of proteins are possi­ble by 2D-PAGE (Polyacrylamide Gel Electrophoresis) and Mass Spectrometry; compa­rative 2-D gel approach or protein chip approach helps to identify the proteins in up or down regulated system. Proteomics complements genomics and is useful when scientists want to test their hypotheses that were based on genes. Sciences, Culinary Arts and Personal The research in proteomics has made it possible to get the know­ledge of all the proteins produced in an organism which may or may not be directly responsible for any phenotypic trait, but this may be helpful to know the functions of all the genes in that organism. However, the efficiency of heavy nitrogen application before drought (NBD) and heavy nitrogen application after drought (NAD) to regulate rice response to drought stress remains controversial.
