Light dependent morphological changes can tune light absorption in iridescent plant chloroplasts

摘要: Abstract Chloroplasts, the organelles responsible for photosynthesis in most plants and algae, exhibit a variety of morphological adaption strategies to changing light environments which can have important yet overlooked scattering effects. This be even more significant iridoplasts, specialized chloroplasts whose tissue is arranged as photonic multilayer producing characteristic strong blue reflectance associated wavelength selective absorption enhancement relevant photosynthesis. In this work, we study how properties iridoplasts are affected by induced dynamic changes using realistic data extracted from previous reports. Our results show red-shift green under increasing intensity. Consequently, nanostructure also redshifted. We that resilient biologically levels disorder structure. extended analysis another nanostructure-containing chloroplast, known bisonoplast, found similar results, pointing towards different plant species. finally all types tune depending on conditions. general, our opens door understanding morphologies affect absorption.
