Subject: Understanding the regulation of plastid morphology in the tropical plant genus Peperomia

Abstract: There is wide variation in the size and number (morphology) of plastids across different plant species and cell types, yet the mechanism by which the cell senses and controls plastid size is unknown. Severe alterations to plastid size can be detrimental, demonstrated in chloroplast division mutants in Arabidopsis thaliana, some of which have dramatically large chloroplasts, which in turn experience high rates of photodamage. We are taking advantage of the extreme natural variation in chloroplast size found within the tropical plant genus Peperomia to identify genes potentially involved in the regulation of chloroplast morphology.
