Alteration in the electron transport activity in thylakoids prepared from control (DMSO) and artemisinin-treated (Artemisinin) rice leaves under basal and uncoupled conditions.

<p>Thylakoids isolated from leaves of control and treated plants were assayed for alteration in basal and uncoupled (NH₄Cl or GS) electron transport activities with FeCN as terminal electron acceptor. Measuring cuvette contained 20 µg Chl. equivalent thylakoids suspension in 1 ml of the reaction medium. The number in parenthesis denotes the electron transport rates in µmol O₂ evolved mg Chl⁻¹ h⁻¹. Arrow up, light on; arrow down, light off. The error bars indicate ±SD of electron transport (n=3).
