Flavodiiron proteins enhance the rate of CO2 assimilation in Arabidopsis under fluctuating light intensity (Plant Physiol)

Plants must adjust to varying levels of light in order to optimize photosynthetic rates; too little electron transport and plants will incur an energetic penalty, while excessive excitation of photosystem I leads to photodamage. During high light conditions, the increase in DpH acts as a brake on electron…

Keeping an “i-on” chloroplast gene expression

DeTar et al. examined whether disruption of ion homeostasis affects plastid gene expression and chloroplast development. Rachael Ann DeTar and Hans-Henning Kunz both at School of Biological Sciences at Washington State University & Plant Biochemistry at LMU Munich Background: Proteins that…
