The Fungal and Bacterial Rhizosphere Microbiome of Solanaceae plants inhabiting the Atacama Desert

Understanding the mechanisms by which the rhizosphere microbiome contribute to the adaptation and tolerance of plants growing under extreme conditions can lead to the development of novel agricultural technologies. The Atacama Desert (AD) is among the most extreme environments on Earth, where inhabiting plants face the lack of rainfall, high salinity and extreme temperature oscillations. Nevertheless, several members of the family Solanaceae are capable of thriving under these adverse conditions. Using high-throughput amplicon sequencing, we explored the composition and diversity of fungal and bacterial communities of the rhizosphere of five Solanaceae species growing in the AD.

解析根际微生物组（rhizosphere microbiome）介导极端环境下植物适应与耐受的机制，可为新型农业技术的研发提供理论支撑。阿塔卡马沙漠（Atacama Desert, AD）是地球极端环境之一，该区域内的本土植物面临降雨匮乏、高盐胁迫与剧烈温度波动等多重逆境。然而，茄科（Solanaceae）的多个物种可在这类恶劣生境中茁壮成长。本研究采用高通量扩增子测序（high-throughput amplicon sequencing）技术，对生长于阿塔卡马沙漠的5种茄科植物的根际真菌与细菌群落组成及多样性展开了系统探究。
