The Physiological Role of Arabidopsis Thylakoid Phosphate Transporter PHT4;1 Chapter

abstract

• Zhejiang University Press, Hangzhou and Springer-Verlag Berlin Heidelberg 2013. The aim of this study was to investigate the physiological role of the thylakoid phosphate transporter PHT4;1 in Arabidopsis thaliana through the analysis of a pht4;1 loss-of-function mutant. Growth of the mutant was reduced in terms of rosette area and biomass to 80% of wild type (WT) values. Analysis of kinetics for slow induction of of chlorophyll fluorescence revealed a transiently higher non-photochemical quenching in the mutant leaves as compared to the WT. On the other hand, relative electron transport rates were as much as 25% lower in the mutant than in WT leaves. These results underscore the fundamental importance of thylakoid phosphate homeostasis for plant growth and modulation of stress responses.
