摘要:
摘要伴随日趋严重的重金属环境污染问题,植物修复的可能机制及重金属胁迫下植物的损伤与抗性机理成为研究热点.采用透射电子显微镜和X射线微区分析技术,研究了中度(50 mg/L)和严重(200 mg/L) Pb2+胁迫下豌豆幼苗根叶细胞的超微结构损伤和铅在植物器官和细胞器水平的区域化分布情况.结果显示,重金属对植物的毒害表现为对细胞的膜结构和各种细胞器的整体性伤害,且各细胞器的受损程度不同;豌豆对铅的相对耐性机理可能包括重金属胁迫下不同细胞器的差异反应、根系富集、细胞壁结合和液泡的区隔化作用等.图6参24
Abstract:
Abstract A growing concern over the issues of phytoremediation and its possible mechanisms towards increasingly serious heavy metal pollution makes this study to deal with some important questions focused on the mechanisms of Pb tolerance and hyperaccumulation in Pisum sativum L. Transmission electron microscopy (TEM) and TEM Xray microanalysis were tandem used to analyze ultrastructural toxic effects and distribution pattern of Pb in organs and organelles of peas at concentrations of 50 mg/L and 200 mg/L Pb2+ as modest and serious stress, respectively. The results indicated that Pb might injure the membranous structures and all the organelles at different extents. The mechanisms of heavy metal resistance to some extent of Pisum sativum might involve the endurance of organelles, accumulation of roots, binding to cell walls, distribution in vacuoles and other possible behaviors at different levels.
