An operon-like transcript has been identified in plants

Operons were thought to be absent in plants. The group of Michael Hothorn now reports the identification of an operon-like transcript in plants that allows for the concerted expression of a previously unknown cell-cycle regulator and a metabolic enzyme. This highly unusual transcript is conserved across the entire plant kingdom and is required for plant embryo development and growth. This study was published on February 8, 2019 in Nature Plants.
