The pigment-binding light-harvesting complex (LHC) proteins of plants and eukaryotic algae are the building blocks of the photosynthetic antenna system. They are responsible for light absorption, energy distribution between the photosystems, and photoprotection. 14 LHC protein types with various properties are known in angiosperms; they belong to three functional groups and are encoded by a family of nuclear genes. In Arabidopsis thaliana, this gene family comprises 21 genes – 17 are abundantly and four are rarely expressed. This review summarizes the structure and function of LHC proteins and focuses on the light regulation of their genes by phytochromes and plastid signals in the contexts of greening and acclimation. Furthermore, the duplication history of the gene family in A. thaliana and expression differences between family members are discussed.
