Study on the effect of elevated CO2 concentration on leaf structure of Brassica juncea L. cv. Bio-141 (95) under moisture stress revealed, that CO2 elevated to 600 μmol mol-1 increased the length of epidermal cel and length of palisade parenchyma cells, and induced larger chloroplasts and more oval shaped starch granules in comparison with plants grown at ambient CO2 concentration. This increase in structural sink size helped in check feedback inhibition by excessive photoassimilate which was subsequently used to compensate the adverse moisture stress effect in B. juncea leaves.

Keywords: chloroplasts; epidermal cells; open top chamber; palisade parenchyma cells; starch granules
Subjects: Brassica juncea; chloroplast, water stress, CO2 concentration; epidermis, water stress, elevated CO2 concentration; open-top chamber, elevated CO2 concentration; palisade parenchyma, elevated CO2 concentration; starch gradules, water stress, elevated CO2 concentration; water stress, elevated CO2 concentration
