For the generation of transgenic plant in crop improvement, one important regulatory gene ‘X’ was overexpressed in a crop plant. Out of 30 transgenic rice plants generated, 22 showed high levels of gene ‘X’ expression. However, rest 8 lines displayed low level of expression. One explanation of such observation may be: 

Suppression effect of the transgene 

Knock down effect of gene X 

Gene silencing effect 

Co-suppression effect of transgene

Selenocysteine is generated enzymatically from serine carried on a special tRNA that is charged by serine-tRNA synthetase. The Sec residues of selenoproteins are thought to participate in redox reactions such as those catalyzed by mammalian glutathione peroxidase and thioredoxin reductase
