Genomic data of <i>Hippophae salicifolia</i> (one female and two male haplotypes)

<i>Hippophae salicifolia</i> (willow-leaved sea buckthorn) is restricted to the Himalayas, to the south of the common sea buckthorn, growing at high altitudes in dry valleys; it differs from <i>H. rhamnoides</i> in having broader and greener (less silvery) leaves, and yellow berries. A wild variant occurs in the same area, but at even higher altitudes in the alpine zone. It is a low shrub not growing taller than 1 m with small leaves 13 cm long. [source Wikipedia]<br> In-depth analysis of the genome of one female and two haplotypes of male <i>Hippophae salicifolia</i>. The genome size of the female was 788.28 Mb. The sizes of the two haplotype genomes were 1,139.98 Mb and 1,097.34 Mb. The sex-determining regions (SDR) of <i>H. salicifolia</i> was 29.71 Mb and contained 249 genes. A comparative analysis of the haplotypes of Chr02 of <i>H. salicifolia</i> revealed that the Y chromosome was shorter than the X chromosome.

背景概述

该数据集提供了柳叶沙棘（Hippophae salicifolia）一个雌性个体和两个雄性单倍型的基因组和转录组数据。雌性基因组大小为788.28 Mb，雄性单倍型基因组大小分别约为1.14 Gb和1.10 Gb，并鉴定出长度为29.71 Mb、包含249个基因的性决定区域（SDR）。分析发现Y染色体较X染色体短，为研究沙棘性别分化提供了重要的基因组资源。
