Research Abstract

Petal senescence is a type of programmed cell death. We showed that expressions of autophagy-associated genes are induced in senescing petals of Japanese morning glory. The induction of autophagy during petal senescence was confirmed by visualizing autophagic structures with the green fluorescent protein (GFP). Our data also suggest that autophagy delays programmed cell death in petal senescence of Japanese morning glory.
