The invasive character of (water hyacinth) is a major threat to global biodiversity and ecosystems. To investigate the genomic basis of invasiveness, we performed the genome and transcriptome sequencing of and reported the genome of 1.11 Gbp size with 63,299 coding genes and N50 of 1.98 Mb. We confirmed a recent whole genome duplication event in that resulted in high intraspecific collinearity and significant expansion in gene families. Further, the orthologs gene clustering analysis and comparative evolutionary analysis with 14 other aquatic invasive and non-invasive angiosperm species revealed adaptive evolution in genes associated with plant-pathogen interaction, hormone signaling, abiotic stress tolerance, heavy metals sequestration, photosynthesis, and cell wall biosynthesis with highly expanded gene families, which contributes toward invasive characteristics of the water hyacinth. However, these characteristics also make water hyacinth an excellent candidate for biofuel production, phytoremediation, and other translational applications.
凤眼蓝的入侵特性对全球生物多样性和生态系统构成了重大威胁。为了探究其入侵性的基因组基础,我们对凤眼蓝进行了基因组和转录组测序,并报道了其大小为1.11 Gbp的基因组,其中有63,299个编码基因,N50为1.98 Mb。我们证实了凤眼蓝近期发生的一次全基因组复制事件,该事件导致了高度的种内共线性和基因家族的显著扩张。此外,通过直系同源基因聚类分析以及与其他14种水生入侵和非入侵被子植物物种的比较进化分析,揭示了与植物 - 病原体相互作用、激素信号传导、非生物胁迫耐受性、重金属螯合、光合作用和细胞壁生物合成相关的基因中存在适应性进化,且基因家族高度扩张,这有助于凤眼蓝的入侵特性。然而,这些特性也使凤眼蓝成为生物燃料生产、植物修复及其他转化应用的理想候选物种。
