Introns may more freely accumulate point substitutions and other changes due to no selection pressure.  Introns evolve or accumulate mutations/changes much more rapidly than exons

Constitutive defenses are costly to the plant. The production of secondary metabolites requires a significant energy investment derived from primary metabolism, which is then unavailable for use in growth and reproduction.

The cytosolic isozymes has two distinct function, It catalyzes the conversion of citrate to isocitrate, providing the substrate for a cytosolic isocitrate dehydrogenase that generates NADPH as reducing power for fatty acid synthesis and other anabolic processes in the cytosol. It also has a role in cellular iron homeostasis

Edible vaccines are produced from transgenic plants in which an orally active antigen of the target pathogen is expressed and accumulated, and which is fed to animals/humans for immunization against the pathogen.
