香榧种仁油脂合成遗传结构和分子机制解析
Transcriptome-referenced association study provides insights into the regulation of oil and fatty acid biosynthesis in Torreya grandis kernel
[目的]香榧(Torreya grandis cv.Merrillii。)属于裸子植物门红豆杉科榧属植物。香榧是我国特产的经济树种,其种仁可食用,并且富含不饱和脂肪酸。然而,在不同地方品种的香榧种仁中,脂肪酸和油含量存在差异。作为裸子植物,香榧是否具有特殊的油脂代谢机制?本研究旨在解析脂肪酸和油脂含量的遗传结构及其潜在分子调控机制。[方法]我们构建了一个高质量的香榧参考基因组,并对 170 个不同香榧地方品种的种仁的 10 个脂肪酸和油脂性状进行…查看全部>>
[Objective]Torreya grandis is a gymnosperm belonging to Taxodiaceae.As an economically important tree,its kernels are edible and rich in oil with high unsaturated fatty acids,such as sciadonic acid.However,the kernels from different T.grandis landraces exhibit fatty acid and oil content variations.As a gymnosperm,does T.grandis have special regulation mechanisms for oil biosynthesis?The aim of this study was to dissect the genetic architecture of fatty acid …查看全部>>
