(e.g., leaves change developmentally from tiny spheroidal shapes to large, thin, complex shapes). One of the goals of the new science of mechanobiology is to understand this two-way street: biology harnesses physics, and physics shapes biology (Robinson et al., 2013;Hamant and Saunders, ...
Under control conditions, the chloroplasts had plump elliptical shapes with a typical lamellar granum structure comprising regular and dense stromal thylakoid and thylakoid arrangements; under salt stress, the chloroplasts had a slim spindle shape with loosely arranged granum thylakoids. In another study,...
