Transformation of chloroplasts to gerontoplasts

The term gerontoplast was first introduced in 1977 to define the unique features of the plastid formed during leaf senescence.

stomata are the last organelles to degrade during senescence, and give plants the green color.[1] The formation of gerontoplasts from chloroplasts during senescence involves extensive structural modifications of the thylakoid membrane with the concomitant formation of a large number of plastoglobuli with lipophilic materials. The envelope of the plastid, however, remains intact.[2]
