Pre mature leaf senescence in rice is one example, but there can be others too. the one on rice leaves is available on 'Plant Physiology' journal's website
thank you very much for your reply, I can use this example in my manuscript, however I'm working on arabidopsis and nicotiana benthamiana. Responses of these two hosts to ABA, in terms of Defense to viruses, are totally opposite to that found in rice.. ABA in rice ABA induces susceptibility to some viruses while it induces tolerance or defenses in benthamiana or arabidopsis
