Plant translation initiation factors: it is not easy to be green

Plants have significant differences in some of the 'parts' of the translational machinery. There are two forms of eukaryotic initiation factor (elF) 41F, elF3 has two novel subunits, elF4B is poorly conserved, and elF2 kinases and elF4E binding proteins (4E-BP) are yet to be discovered. These differences suggest that plants may regulate their translation in unique ways.
