Pathology & Biotechi
Disruption phenotypei
Displays no resistance to potyvirus. Possesses reduced amounts of chlorophyll a and b. I4g1 and i4g2 double mutants show reduced germination rates, slow growth rates, moderate chlorosis, late flowering, impaired fertility and reduced long term seed viability. They also exhibit altered responses to dehydration, salinity, and heat stress. The i4g1 and i4g2 double mutant has reduced amounts of chlorophyll a and b.2 Publications

Interactioni
Subunit structurei
EIF4F is a multi-subunit complex, the composition of which varies with external and internal environmental conditions. It is composed of at least EIF4A, EIF4E and EIF4G. In higher plants two isoforms of EIF4F have been identified, named isoform EIF4F and isoform EIF(iso)4F. Isoform EIF4F has subunits p220 and p26, whereas isoform EIF(iso)4F has subunits p82 and p28.
