2020年6月25日 · Our results reveal that an increased MGDG : DGDG ratio is the primary cause of JA overproduction. The ratio is also important for determining chloroplast shapes, whereas reduced Chl and photosynthesis are most likely a direct consequence of insufficient DGDG.

2014年4月1日 · In this review, we have shown that MGDG, DGDG, PG and SQDG have been conserved from cyanobacteria to primary plastids. The relative proportions of each lipid result from highly regulated and compartmentalized metabolic pathways. The MGDG/DGDG ratio appears critical for the appropriate structure of thylakoid membranes.

Monogalactosyldiacylglycerol (MGDG) 和 digalactosyldiacylglycerol (DGDG) 一起构成了叶绿体脂质的大约 80%。 除了促进类囊体膜中的光合作用光反应外，这两种脂质对于维持叶绿体形态和植物在非生物胁迫（如磷酸盐饥饿和冷冻）下的生存也很重要。

陈晓龙研究发现，在低温胁迫下增加dgdg/mgdg的比值，可以维持质膜的流动性，降低低温对植物的伤害 。 王玉萍等研究发现，通过低温处理后的芸豆 Phaseolus vulgaris 子叶脂质组成中双半乳糖脂甘油二酯(DGDG) 的含量显著增加，使黄瓜幼苗的低温抗性提高 [ 49 ] 。

Acylated monogalactosylmonoacylglycerol (acMGDG) is formed mainly by transfer of a glycerol-linked fatty acid of DGDG to the galactose of MGDG, producing digalactosylmonoacylglycerol (DGMG) as a by-product, although some acMGDG can be produced by transfer of an acyl group from one MGDG to the galactose of another with formation of ...

Thylakoid membrane synthesis involves complex processes for assembling photosynthetic proteins and pigments within membrane lipids, which mainly comprise the galactolipids monogalactosyldiacylglycerol (MGDG) and digalactosyldiacylglycerol (DGDG). In chloroplasts, MGDG and DGDG account for approximately 50 and 25 mol% of thylakoid membrane ...

Our results reveal that an increased MGDG : DGDG ratio is the primary cause of JA overproduction. The ratio is also important for determining chloroplast shapes, whereas reduced Chl and photosynthesis are most likely a direct consequence of insufficient DGDG.

Monogalactosyldiacylglycerol (MGDG), the most abundant lipid in thylakoid membranes, is involved in photosynthesis and chloroplast development. MGDG lipase has an important role in lipid remodeling in Chlamydomonas reinhardtii. However, the process related to turnover of the lysogalactolipid that results from MGDG degradation ...

2019年7月1日 · MGDG is a major component of thylakoid membranes, and accounts for 50 mol% of the total glycerolipid content in chloroplasts. In the leaves of Arabidopsis, MGDG acyl groups are composed of 60 mol% of 18:3 and 30 mol% of 16:3. MGDG is essential for thylakoid biogenesis in plant leaves [95,96,127].

mgdg 标准品，通过解析其ms/ms 断裂规律，总结碎片离子； 然后摸索其CE, DP, CXP 等质谱参数；根据断裂规律和质谱参数， 建立测定SQDG, DGDG和MGDG 脂族的MRM 方法。
