Title [sv]
LHC proteinernas struktur och funktion
Title [en]
Structure and function of the proteins of the LHC family
Abstract [sv]
This research project adress how green plants harvest light for use in photosynthesis. We will study the function of the light-harvesting antenna using a combination of molecular genetics, biochemistry, biophysics, physiology and ecophysiology. We will, in particular, study the roles of the Lhcb1 and Lhcb2 proteins using our recently developed Arabidopsis lines lacking these proteins by means of amiRNA. For the first time the functions of these proteins ? which may be the most abundant membrane proteins on earth ? can be dissected, and we will focus on their role in regulatory processes like ?state transitions? and ?non-photochemical quencing?. The important regulatory phosphorylation of the proteins can also be studied using our develop antibodies against the phosphorylated forms. We will also study the structure and function of Lhcb7, an LHC protein which is much less abundant, but also a group of related proteins, the so-called Lil (Light-harvesting like) proteins which seems to function as pigment carriers or insertion factors. Other photosynthetic regulatory processes will also, albeit to a less extent, be studied, in particular in field experiments with transgenic plants.
