Abstract
In plants, lipids function in a variety of ways. Lipids are a major component of biological membranes and are used as a compact energy source for seed germination. Fatty acids, the major lipids in plants, are synthesized in plastid and assembled by glycerolipids or triacylglycerols in endoplasmic reticulum. The metabolism of fatty acids and triacylglycerols is well studied in most Arabidopsis model plants by forward and reverse genetics methods. However, research on the diverse functions of lipids in plants, including various crops, has yet to be completed. The papers of this Special Issue cover the core of the field of plant lipid research on the role of galactolipids in the chloroplast biogenesis from etioplasts and the role of acyltransferases and transcription factors involved in fatty acid and triacylglycerol synthesis. This information will contribute to the expansion of plant lipid research.
摘要
在植物中，脂质发挥着多种作用。脂质是生物膜的主要成分，并用作种子萌发的紧凑能量来源。脂肪酸是植物中的主要脂质，在质体中合成，并在内质网中由甘油脂或三酰甘油组装而成。通过正向和反向遗传学方法，在大多数拟南芥模式植物中对脂肪酸和三酰甘油的代谢进行了深入研究。然而，关于脂质在包括各种作物在内的植物中的多种功能的研究尚未完成。本期特刊的论文涵盖了植物脂质研究领域的核心内容，涉及半乳糖脂在黄化质体向叶绿体生物发生中的作用以及参与脂肪酸和三酰甘油合成的酰基转移酶和转录因子的作用。这些信息将有助于拓展植物脂质研究。
