Plastoglobuli increase during senescence of leaves, and as abiotic stress in general accelerate leaf senescence, these' globuli' increase in chloroplasts.

Thank you very much, I know that but what about the role of lipoprotein within plastoglouli.

Derek Richard du Preez

This paper provides some interesting discussion on the role of plastoglobules: Bréhélin C, Kessler F, Van Wijk KJ (2007) Plastoglobules: versatile lipoprotein particles in plastids. Trends in Plant Science 12: 260–266

Thank you very much for your great attentions

I know well that plastoglobuli accelerate senescenece of leaves, but what its mode of action.

Massimo Nepi

Plastoglobules contain also b-carotene that protect against oxidative stress. Senescence is frequently associated with increasing level of ROS and these may be a reason why they increased in senescent leaves. See American Journal of Botany 94(1): 12–24. 2007.
