A method of altering fatty acid and/or triacylglycerol production in plants and/or algae is provided. The method includes altering activity levels of alpha-carboxyltransferase (α-CT), a catalytic subunit of acetyl-CoA carboxylase (ACCase) by modulating an expression of at least one carboxyltransferase interaction (CTI) gene encoding at least one CTI protein.

The invention provides an isolated nucleic acid having a sequence encoding a spermidine/spermine acetyltransferase (SSAT), wherein translation of an mRNA comprising the encoded SSAT has increased basal translation and increased stimulated translation, compared to a wild-type mRNA encoding SSAT. Methods of use for the nucleic acid are also provided. Methods and compositions are also provided for reducing ischemia-reperfusion injury in organs or tissue for transplantation.

A method of altering fatty acid and/or triacylglycerol production in plants and/or algae is provided. The method includes altering activity levels of alpha-carboxyltransferase (-CT), a catalytic subunit of acetyl-CoA carboxylase (ACCase) by modulating an expression of at least one carboxyltransferase interaction (CTI) gene encoding at least one CTI protein.
