Microbial communities of desert plants Targeted loci environmental. Microbial communities of desert plants

Deserts in Saudi Arabia are one of the most hostile places for plant growth. However, desert plants can still grow under these extreme conditions and might reveal interesting survival strategies. In this study, we examined the soil, rhizosphere and endosphere microbiome of four native desert plants, Tribulus terrestris, Zygophyllum simplex, Panicum turgidum and Euphorbia granulate, at two sites, Midwest (Al Wahbah) and Southwest (Jizan) of Saudi Arabia, with different soil physicochemical properties.

沙特阿拉伯境内的沙漠是植物生长最为严苛的生境之一。即便身处这类极端环境，沙漠植物仍可存活，并可能展现出颇具研究价值的生存策略。本研究以沙特阿拉伯中西部（阿尔瓦赫巴，Al Wahbah）与西南部（吉赞，Jizan）两个土壤理化性质存在差异的区域为采样点，对蒺藜（Tribulus terrestris）、单叶霸王（Zygophyllum simplex）、壮稷（Panicum turgidum）及颗粒大戟（Euphorbia granulate）四种本土沙漠植物的土壤、根际（rhizosphere）及内生境（endosphere）微生物组（microbiome）进行了分析。
