Narciclasine (NCS) is a plant growth inhibitor isolated from the secreted mucilage of Narcissus tazetta bulbs. It is a commonly used anticancer agent in animal systems. In this study, we provide evidence to show that NCS also acts as an agent in inducing programmed cell death (PCD) in tobacco Bright
