Are plant genes different?

Abstract
The mRNAs from animal systems are now known to have some conserved sequences in common, and a characteristic codon usage. Very few plant genes or cDNAs have been sequenced so far and it has not been possible to say therefore whether they share these characteristics as well. This paper presents sequence data from cDNAs coding for the major storage proteins of pea and compares these plant data with the concensus features of animal genes. The codon usage of plants is different from that of animals and more variability occurs in the conserved sequences in the 3′ untranslated region.
