摘要

浮萍分布全球,在植物修复和营养以及发展的基础研究中有着广泛的应用。现有的收集中与自然栖息地相关的环境数据很少。因此,在原生生境的背景下,缺乏对自然变异的理解。在这里,通过基因组测序和基因组学对来自英国115个地点的124种浮萍进行了鉴定。在普通富营养化条件下,浮萍的磷、钾、镁、钙均呈超积累状态。在普通富营养化条件下,浮萍的元素组成与原生水体剖面存在局域关联,但不存在大尺度关联。小蓝藻是英国最常见的物种,与之密切相关的杂交品种日本蓝藻经常在微量元素浓度较高的水域中发现。入侵L. minuta在南部和中部地区很常见,但在苏格兰受到限制。菜菜中重金属污染物通常与常量营养素一起积累,提示植物修复潜力,但作为食物存在一定局限性。此外,为了保护生物多样性,应持续监测本地、杂交和入侵种之间的生态相互作用。

An ecological, phenotypic, and genomic survey of duckweeds with their associated aquatic environments in the United Kingdom.

The duckweeds feature global distributions and diverse applications in phytoremediation and nutrition, as well as use in fundamental studies of development. Existing collections have minimal environmental data linked to natural habitats. Thus, there is a lack of understanding of natural variation in the context of native habitats. Here, a novel collection of 124 duckweed accessions from 115 sites across the United Kingdom was characterized by genome sequencing and ionomics. In common nutrient-replete experimental conditions, all accessions hyperaccumulated P, K, Mg and Ca. Local but not large-scale associations were revealed between elemental composition of duckweed in common, replete conditions and native water profiles. Lemna minor was the most prevalent species in the UK, with a closely related hybrid L. japonica frequently found in waters with higher micronutrient concentrations. Invasive L. minuta was common in the southern and midland regions, but restricted in Scotland. Lemna accessions accumulated heavy metal contaminants typically together with macronutrients, suggesting phytoremediation potential, but some limitations as food. Furthermore, monitoring the ecological interactions between native, hybrid and invasive Lemna species should be ongoing in the interest of biodiversity.
