   2.4.1.46 | malfunction |
an enzyme.deficient mutant has dwarf and albino phenotypes and the development of its thylakoid membranes is almost completely perturbed |
733407 |
| 2.4.1.46 | malfunction |
enzyme knockout causes albino seedlings. Strong enzyme suppression causes substantial decreases in galactolipid content in cotyledons, leading to severe defects in the formation of thylakoid membranes and impaired photosynthetic electron transport |

the enzyme catalyzes the final step of monogalactosyldiacylglycerol synthesis in plants, regulation of MGDG synthesis during chloroplast development, overview |

| 2.4.1.46 | metabolism |
the galactolipid monogalactosyldiacylglycerol is the major lipid in plastids, and is mainly synthesized in inner plastid envelopes, where monogalactosyldiacylglycerol synthase 1, MGD1, catalyses the last step of its production |

| 2.4.1.46 | physiological function |
compared to wild-type, transgenic Nicotiana tabacum plants overexpressing rice monogalactosyldiacylglycerol synthase (MGD) gene and wild-type tobacco plants exposed to AlCl3 exhibit rapid regrowth of roots after removal of Al and less damage to membrane integrity and lipid peroxidation under Al stress, while the Al accumulation shows no difference between wild-type and transgenic plants. Al treatment dramatically decreases the content of monogalactosyldiacylglycerol and the ratio of monogalactosyldiacylglycerol to digalactosyldiacylglycerol in wild-type plants, while it is unchanged in transgenic plants. The stable monogalactosyldiacylglycerol level and the ratio of monogalactosyldiacylglycerol/digalactosyldiacylglycerol contribute to maintain the membrane stability and permeability. Al causes a significant increase in phospholipids in wild-type plants, resulting in a high proportion of phospholipids and low proportion of galactolipids, but these proportions are unaffected in transgenic plants |

| 2.4.1.46 | physiological function |
complete loss causes kernel lethality owing to failure in both endosperm and embryo development |

| 2.4.1.46 | physiological function |
enzyme overexpression improves salt tolerance in tobacco |

| 2.4.1.46 | physiological function |
essential gene, growth impaired in knockdown mutant, role in chlorosome biogenesis |
720684 |
| 2.4.1.46 | physiological function |
isoform MGD1 function may link galactolipid synthesis with the coordinated transcriptional regulation of chloroplasts and other organelles during cotyledon greening |
737027 |
| 2.4.1.46 | physiological function |
isoform MGD3 plays a role in plant growth under sucrose-replete conditions. Isoform MGD3 plays an important role in supplying 1,2-diacyl-3-O-(beta-D-galactosyl)-sn-glycerol as a component of extraplastidial membranes to support enhanced plant growth under conditions of carbon excess |
