在两种双子叶植物拟南芥和烟草中表达了来自单子叶玉米的花青素途径特异性转录激活因子兰德C1。R的表达引起增强花青素色素沉着的植物物种和增强毛状体（头发）的生产在拟南芥。单独使用C1没有效果。表达C1和R的杂交转基因拟南芥在根、花瓣和雄蕊组织中产生了通常不表达花青素的花青素。当R在拟南芥的透明种皮无毛（没有花青素和毛状体）突变体中表达时，花青素和毛状体的缺陷得到了补充。
Anthocyanin pathway-specific transcriptional activators Rand C1 from the monocot maize were expressed in two dicots, Arabidopsis thaliana and Nicotiana tabacum. Expression of R caused augmented anthocyanin pigmentation in both plant species and augmented trichome (hair) production in Arabidopsis. Alone, C1 had no effect. Hybrid transgenic Arabidopsis expressing both C1 and R produced anthocyanins in root, petal, and stamen tissues that normally never express anthocyanins. When R was expressed in the transparent testa glabrous (without anthocyanins and trichomes) mutant of Arabidopsis, the deficiency was complemented and both anthocyanins and trichomes were restored.
