Rabbit to the Rescue?

It has been reported that a modified 'rabbit gene' has been inserted by GM technology into Devil's ivy, a house plant (https://www.theguardian.com/environment/2018/dec/19/houseplant-rabbit-dna-reduce-air-pollution-study-devils-ivy). The gene enables the plant filter out harmful pollutants such as chloroform and benzene. As I keep telling my students, the gene is not necessarily the exclusive property of the rabbit (many genes are shared by organisms e.g. humans share circa 20% of the genes a yeast has). So the rabbit was, presumably, a convenient source.
