Pyruvate orthophosphate dikinase (PPDK) as a putative key regulator of diurnal deacidification in CAM leaves across varying light intensities and photoperiods
Abstract. Crassulacean acid metabolism (CAM) plants primarily fix atmospheric CO2 at night and store it as malic acid in their vacuoles. During daytime, va
