To consider whether defective of LHCs controlled glutathione (GSH) levels that modulate light-induced plant growth, we assessed light related parameters using chlorinal-1 (ch1-1) mutant, a GSH deficient mutant due to defective of LHCs, and linked this with wild-type (WT) Arabidopsis plants. The ch1-1 mutants accumulated significantly lower levels of non-photochemical quenching (qn and NPQ), an efficient quantum yield of PSII {Y (II)} and regulated energy dissipation of PSII {Y (NPQ)} than WT plants. The growth of leaf and plant decreased in the ch1-1 mutant plants compared to the WT plants. These results suggest that defective of LHCs might control the growth of the ch1-1 mutant Arabidopsis plants through regulating the GSH levels and light energy in PSII. 27th Malaysian Society of Plant Physiology Conference Pulai Springs Resort, Johor, Malaysia |
