科学家揭示根系分泌物在植物-土壤反馈中的作用(图)
科学家 根系分泌物 植物土壤反馈
2019/5/10
植物可以通过向根际分泌生物活性分子来改变土壤微生物群,从而影响其后代的表现。根系分泌物除了为微生物生长提供碳和氮底物外,还作为信号分子、引诱剂、刺激剂、抑制剂和排斥剂来影响根际微生物。植物-土壤反馈是决定植物演替、植物种群、群落结构和植物多样性的重要因素。植物土壤反馈通常与土壤生物群的变化有关。特别是土壤微生物群落的组成被认为是这方面的一个重要因素。虽然有研究团队研究了几种微生物对植物生长性能的影...

2018年1月19日出版发行的最新一期《科学》(Science)期刊登载了由欧盟研究理事会(ERC)资助的、西班牙胡安·卡洛斯大学费尔南德?麦斯特雷等人合作完成的报告《全球优势土壤细菌地图》(A global atlas of the dominant bacteria found in soil)。土壤细菌在调节陆地碳动态、养分循环和植物生长方面起着关键作用,但是土壤细菌群的巨大多样性阻碍了人类...
森林火灾残留木炭可能促进二氧化碳排放
森林 火灾残留 木炭 二氧化碳
2018/1/3
在储存地球温室气体二氧化碳方面,森林发挥着重要作用。然而森林火灾会大大削弱这种作用。一项国际最新研究发现,森林火灾后留下的木炭会促进土壤中树木细根的分解,而这会促使蓄积在细根中的二氧化碳释放。
