人类对桑蚕相互作用的利用始于至少5000年前，并通过丝绸之路极大地影响了世界历史。作为家蚕基因组序列的补充，我们在这里描述了桑树物种Morus notabilis的基因组。在330-Mb的基因组序列中，我们鉴定出128 Mb的重复序列和29338个基因，其中60.8%得到转录组测序的支持。桑树基因序列的进化速度似乎比其他罗萨勒斯品种快3倍，这可能促进了该物种在世界范围内的传播。桑树是为数不多的菊科植物之一，但也有一些罗萨莱属植物在1亿多年的时间里没有保存基因组复制；然而，在桑树和其他几种树中发现的新多倍体系列表明，新的复制可能带来好处。在家蚕的血淋巴和丝腺中发现了五个预测的桑树mirna，这表明在植物-食草关系中存在分子水平的相互作用。对桑树在乳汁管中表达的与多样化选择、抗性和蛋白酶抑制剂有关的基因进行鉴定和分析，将加速桑树的改良。桑树是蚕的主要食物来源，养蚕是为了产丝。在本研究中，He等人展示了桑（Morus notabilis）的基因组序列草图，发现桑的进化速度明显快于其他Rosales目植物。
Human utilization of the mulberry–silkworm interaction started at least 5,000 years ago and greatly influenced world history through the Silk Road. Complementing the silkworm genome sequence, here we describe the genome of a mulberry species Morus notabilis. In the 330-Mb genome assembly, we identify 128 Mb of repetitive sequences and 29,338 genes, 60.8% of which are supported by transcriptome sequencing. Mulberry gene sequences appear to evolve ~3 times faster than other Rosales, perhaps facilitating the species’ spread worldwide. The mulberry tree is among a few eudicots but several Rosales that have not preserved genome duplications in more than 100 million years; however, a neopolyploid series found in the mulberry tree and several others suggest that new duplications may confer benefits. Five predicted mulberry miRNAs are found in the haemolymph and silk glands of the silkworm, suggesting interactions at molecular levels in the plant–herbivore relationship. The identification and analyses of mulberry genes involved in diversifying selection, resistance and protease inhibitor expressed in the laticifers will accelerate the improvement of mulberry plants. Mulberry trees are the primary food source for silkworms, which are reared for the production of silk. In this study, He et al. present the draft genome sequence of Morus notabilis and find that it evolved significantly faster than other plants in the Rosales order.
