  1. 1. The roles of Lhcb1 och Lhcb2 in regulation of photosynthetic light harvesting

    Författare :Malgorzata Pietrzykowska; Stefan Jansson; Jean-David Rochaix; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis; Lhcb1; Lhcb2; LHCII; state transitions; phosphorylation; biology; biologi;

    Sammanfattning : Photosynthesis in higher plants relies upon collection of light by chlorophyll molecules associated with light harvesting chlorophyll a/b-binding (LHC) proteins. The two most abundant of these are Lhcb1 and Lhcb2, which make up light harvesting complex (LHC) II trimers. LÄS MER

  3. 2. Dissecting the photosystem II light-harvesting antenna

    Författare :Jenny Andersson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plant physiology; antisense; Arabidopsis thaliana; chlorophyll; carotenoid; feedback de-excitation; fitness; LHC; NPQ; photosynthesis; state transitions; xanthophyll; Växtfysiologi; Plant physiology; Växtfysiologi; Physiological Botany; fysiologisk botanik;

    Sammanfattning : In photosynthesis, sunlight is converted into chemical energy that is stored mainly as carbohydrates and supplies basically all life on Earth with energy.In order to efficiently absorb the light energy, plants have developed the outer light harvesting antenna, which is composed of ten different protein subunits (LHC) that bind chlorophyll a and b as well as different carotenoids.

  4. 3. Phosphorylation in State Transition : Less cause more effect

    Författare :Jakob Damkjaer; Jansson Stefan; Eva-Mari Aro; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Photosynthesis; Photoacclimation; State Transtion; LHCII Phosphorylation; Lhcb3; Lhcb6; Plant physiology; Växtfysiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : Study of the Arabidopsis thaliana knockout mutant lacking Lhcb3 (koLhcb3) have revealed a close similarity to the wild type plants. Growth rate, NPQ, qP, Φ(PSII), circular dichroism spectra, pigment composition and content of LCHII trimers have been found to be unaffected by this mutation. LÄS MER
