The bZIP intron plant is an unconventional bZIP intron in plants located in the mRNA of bZIP60 orthologs. The consensus RNA structure is very similar to the animal variant with short, usually 23 nt

intron An intron is any nucleotide sequence within a gene that is not expressed or operative in the final RNA product. The word ''intron'' is derived from the term ''intragenic region'', i.e., a region inside a gene."The notion of the cistron .e., gen ...
