概括

Pteris vittata通过其根从土壤中吸收微塑料 (MP),并将其运送到叶子上. 这种树显示出植物管理策略的潜力,以减轻陆地生态系统中的MP污染.

科学领域:

环境科学环境科学
植物生物学植物生物学
生态毒理学生态毒理学

背景情况:

微塑料 (MP) 污染在陆地生态系统中越来越令人担忧,污水污泥应用是主要来源.
议员的规模较小,持久性和广泛分布使得他们的移除具有挑战性.
植物补救,使用植物进行现场补救,是一种可持续的方法,但对MP的应用研究不足.

研究的目的:

调查Pteris vittata在从土壤中去除微塑料 (MP) 的潜力.
为了确定P. vittata是否可以从污水污泥改变的土壤中吸收和转移MP.
评估MPs对P. vittata生理学和基因表达的影响.

主要方法:

Pteris vittata是在用含有各种微塑料聚合物的污水污泥修改的土壤上种植的.
分析了MP的吸收和转移到根和树叶的位置.
测量了植物生物识别指数,氧化应激和水素素基因的表达.

主要成果:

皮特里斯·维塔塔通过其根源证明了多种MP类型 (PE,PP,PA,PU,PET,PVA,PS,EVA,PMMA,ABS) 的吸收.
观察到几种MP类型 (PE,PA,PP,PU,PET,PVA,EVA,PVC) 的转移到叶片上.
污水污泥度增加导致植物中的MP含量增加,但减少了植物生长,并抑制了根部的特定基因表达.

结论:

虫可以吸收和转移微塑料 (MPs) 从土壤到它的地面组织.
类植物在陆地环境中具有植物稳定或MP植物管理的潜力.
MPs在P. vittata根部诱导局部生理应激,影响基因表达.

Epiphytes, Parasites, and Carnivores

Plants often form mutualistic relationships with soil-dwelling fungi or bacteria to enhance their roots’ nutrient uptake ability. Root-colonizing fungi (e.g., mycorrhizae) increase a plant’s root surface area, which promotes nutrient absorption. While root-colonizing, nitrogen-fixing bacteria (e.g., rhizobia) convert atmospheric nitrogen (N2) into ammonia (NH3), making nitrogen available to plants for various biological functions. For example, nitrogen is essential for the...

Rhizaria are a diverse group of unicellular protists characterized by their threadlike cytoplasmic extensions known as pseudopodia. These structures aid in both locomotion and feeding, giving Rhizaria an amoeboid appearance. Their amoeboid morphology once led to taxonomic confusion, but molecular phylogenetics has clarified their evolutionary placement and emphasized their shared use of pseudopodia despite divergent lineages.This clade comprises diverse lineages such as Chlorarachniophyta,...
