construction of a mgd1-1 knockdown mutant, targeting of chloroplast proteins is not affected in mgd1-1 mutants, but in dark-grown mgd1-1 plants the photoactive to photoinactive protochlorophyllide ratio is increased, and photoprotective responses are induced. Mutant mgd1-1 cannot withstand high light intensities, apparently due to impairment of another photoprotective mechanism, steady-state capacity of the xanthophyll cycle is reduced in mgd1-1 mutants mediated by increased conductivity of the thylakoid membrane leading to a higher pH in the thylakoid interior, which impairs the pH-dependent activation of violaxanthin de-epoxidase and PsbS, phenotype, overview. Knockdown mgd1-1 mutant accumulates about 40% less galactolipid monogalactosyldiacylglycerol than wild type |

identification of a naturally occuring Arabidopsis MGD1 mutant showing a complete defect in MGDG synthase 1, the mutant seedlings show a lack in galactolipids and disrupted photosynthetic membranes, leading to the complete impairment of photosynthetic ability and photoautotrophic growth, Dwarf and Albino phenotypes, overview |
