摘要
植物根圈与细菌群落的结合为其适应沙漠生态系统的不利条件提供了巨大优势。在墨西哥索诺拉沙漠,由于高盐度、干旱和极端温度的严重影响,物种多样性很低。然而,Parkinsonia aculeata L. 是适应这些不利环境条件的特有物种。在此,我们旨在分离与生长在盐碱地(BL 地点)和干旱地(RT 地点)的 P. aculeata 根圈相关的细菌分离物,并对其进行分子鉴定。通过 16S rDNA 测序,共鉴定出 33 个来自 P. aculeata 根圈的细菌分离物,发现它们属于以下属:芽孢杆菌属、肠杆菌属、普里斯特菌属、 Sinomonas 菌属、微球菌属、球菌属、葡萄球菌属、链霉菌属、节杆菌属和 Peribacillus 属。在这两个地点,普里斯特菌属所占比例最大,其次是芽孢杆菌属和葡萄球菌属。此前曾有报告称,分离出的菌株表现出对植物有益的特性,能促进植物生长,保护土壤,为开发环境友好型农业替代品提供了机会,并可用作研究干旱/盐分缓解的实验模型。
Rhizobacteria associated with Parkinsonia aculeata L. under semi desertic drought and saline conditions
Plants rhizosphere and bacterial communities’ association offer great advantages for its adaptation to adverse conditions in desert ecosystems. In the Sonoran Desert, Mexico, there is low diversity of species due to the significant incidence of high salinity, drought and extreme temperatures. However, Parkinsonia aculeata L. is an endemic species adapted to these adverse environmental conditions. Here, we aimed to isolate and molecularly characterize bacterial isolates associated with P. aculeata rhizosphere grown in saline soils (BL site) and drought (RT site). A total of thirty-three bacteria isolates from the P. aculeata rhizosphere were identified by 16S rDNA sequencing finding members of the genera: Bacillus, Enterobacter, Priestia, Sinomonas, Micrococcus, Kocuria, Staphylococcus, Streptomyces, Arthrobacter and Peribacillus. Priestia followed by Bacillus and Staphylococcus genus showed the major abundance percentages in both sites. The isolated strains were previously reported to exhibit plant beneficial traits, promote plant growth preserve the soil, provide an opportunity for the development of environmentally friendly alternatives for agriculture and to be used as experimental models to study drought/salt mitigation.
