The effect of seed tuber tare soil on the potato rhizosphere microbiome

Understanding the factors influencing microbiome composition in the rhizosphere is an important step towards managing the microbiomes of globally important crops like potato. We tested whether potato tare soil (i.e. soil adhering to the tuber surface) on seed tubers influences microbial community composition of the developing rhizosphere using a surface sterilization treatment to remove tare soil from seed tubers compared to a control group. We used ITS and 16S metabarcoding to characterize the fungal and bacterial rhizosphere communities of 300 potato plants grown from the experimental seed tubers.

探究影响根际微生物群组成的因素是管理如马铃薯等全球重要作物微生物群的关键步骤。本研究旨在验证马铃薯块茎土壤（即附着在块茎表面的土壤）是否会影响发育中的根际微生物群落组成，通过对比表面灭菌处理去除种子块茎上的土壤与对照组的处理，进行实验研究。我们采用ITS和16S metabarcoding技术对来自实验种子块茎的300株马铃薯的根际真菌和细菌群落进行特征化分析。
