Disruption of Thylakoid-associated Kinase 1 Leads to Alteration of Light Harvesting in Arabidopsis (original) (raw)

Disruption of Thylakoid-associated Kinase 1 (TAK1) in Arabidopsis leads to significant alterations in light harvesting processes by affecting the phosphorylation of light harvesting complex proteins (LHCP). The study uncovers the role of TAKs in state transitions, highlighting their essential function in balancing the absorption of light energy between photosystem I (PSI) and photosystem II (PSII). Mutant analyses indicate that loss of TAK1 results in diminished LHCP phosphorylation and impaired state transitions, underscoring the critical nature of these kinases in the photosynthetic response to varying light conditions.
