Ginger is a perennial monocotyledonous herb, which can be used as both a vegetable and a medicinal plant. However, it is susceptible to various plant pathogens. Microbial diversity in soil is related closely to the health and productivity of plant crops including ginger. In the current study, we compared microbial diversity from soil samples under ginger cultivation (disease incidence of >50% [relatively unhealthy sample] versus disease incidence of <10% [relatively healthy sample]). The bacterial and fungal taxa were analyzed by Illumina-based sequencing, with 16S and ITS identification, respectively. Both bacterial and fungal OTUs were significantly more in the healthy soil sample than the unhealthy sample. Moreover, the dominant bacterial and fungal genera were detected to be different in each sample. and were the dominant bacterial genera in the healthy sample, while and were the dominant genera in the unhealthy sample. For fungal analysis, , , and were the dominant genera in the healthy sample, while , , and were the dominant genera in the unhealthy sample. Collectively, the basic information of microbial diversity in ginger soil is helpful for elucidating the ginger-microbe interactions and potentially selecting suitable plant growth-promoting rhizobacteria and biocontrol agents for ginger production.
生姜是一种多年生单子叶草本植物，既可以用作蔬菜，也可以作为药用植物。然而，它易受多种植物病原体的侵害。土壤中的微生物多样性与包括生姜在内的农作物的健康和生产力密切相关。在本研究中，我们比较了生姜种植土壤样本中的微生物多样性（发病率>50%[相对不健康样本]与发病率<10%[相对健康样本]）。通过基于Illumina的测序分别对细菌和真菌分类群进行分析，使用16S和ITS进行鉴定。健康土壤样本中的细菌和真菌OTU均显著多于不健康样本。此外，每个样本中检测到的优势细菌和真菌属不同。健康样本中的优势细菌属为 和 ，而不健康样本中的优势属为 和 。对于真菌分析，健康样本中的优势属为 、 和 ，而不健康样本中的优势属为 、 和 。总体而言，生姜土壤中微生物多样性的基本信息有助于阐明生姜与微生物的相互作用，并有可能为生姜生产选择合适的促进植物生长的根际细菌和生物防治剂。
