Achieving high levels of transgene expression is often crucial for the effective production of high value pharmaceutical proteins and bioactive compounds. Here, we show a 79-nucleotide sequence of the 5 UTR of the Arabidopsis thaliana cysteine-rich transmembrane module 1 (CYSTM1) significantly increases transient and stable transgene expression at the post-transcriptional level in multicellular plants, A. thaliana and Nicotiana benthamiana, in monocotyledon wheat germ extracts, and in the unicellular bacterium Escherichia coli by up to 7-fold. We also show the 79 nt CYSTM sequence has 50 % higher transgene expression than the broadly used Tobacco Mosaic Virus omega ({Omega}) sequence in both A. thaliana and N. benthamiana. Taken together, this study provides a short transgene expression enhancer for multicellular and unicellular organisms.
