[Identification of SPS family genes and regulation of photosynthetic pigment stability by PthSPS1/2/3 in Populus cv.741].
Physiological and biochemical analyses showed that the content of SPP, chlorophyll a, chlorophyll b, chlorophyll b, and carotenoids were significantly lower in the albino mutants (pthsps1/2/3) than in the wild type, indicating that PthSPS1/2/3 regulated the stability of photosynthetic pigments.
