Adaptive Root of Mangrove Plant Avicennia marina: Structure and Transcriptome Analyses

Abstract

红树林泛指生长在热带、亚热带地区河口或海岸潮间带的木本植物群落,是适应陆地与海洋过渡区域的一种特殊森林类型。白骨壤(Avicenniamarina)是红树林中常见的红树植物,是群落演替中的先锋物种。对于生长在滨海湿地相对低氧环境的白骨壤而言,其根系统对湿地环境有高度专业化的适应。根据白骨壤根结构生长位置和生长方向不同,将其分为四种根结构,分别为在地面下方水平生长且围绕树干延伸数米的水平根(Cableroot)、垂直于水平根向地下生长的锚定根(Anchorroot)、垂直于水平根向地上生长并且从泥土浮现在地上的呼吸根(Pneumatophore)及从在呼吸根基部水平方向长出来的直径较细的营养根(...Mangrove is a type of woody plant community that resides in tropical, subtropical estuaries and coastal intertidal zones. Mangrove is also a special forest type that adapts to the transitional area between land and ocean. Avicennia marina is a kind of common mangrove species, and the pioneer species in community succession. A. marina lives in relatively low oxygen environment in coastal wetlands a...学位:理学硕士院系专业:环境与生态学院_生态学学号:3312014115166
