Abstract
The size and shape of organelles can influence the rate of biochemical reactions in cells. Previous studies have suggested that organelle morphology changes due to intra‐ and extracellular environmental responses, affecting the metabolic efficiency of and signal transduction emanating from neighboring organelles. In this study, we tested the possibility that intracellularly distributed organelles exhibit a heterogeneous response to intra‐ and extracellular environments. We detected a high correlation between peroxisome morphology and distance to the nucleus in light‐exposed cells. Moreover, the proximity area between chloroplasts and peroxisomes varied with distance to the nucleus. These results indicate that peroxisome morphology varies with proximity to the nucleus, suggesting the presence of a nucleus–peroxisome signal transduction cascade mediated by chloroplasts.
