Evaluation of Microbial Diversity in Ginger-Cultivated Soil

Yehia Mashad, Megdi Yacaub, Ibrahim Abeuleish

A perennial herb known as ginger is a monocotyledon that has both culinary and medicinal uses. It is vulnerable to a number of plant diseases, though. The health and production of plant crops, including ginger, are directly correlated with the diversity of microbes in the soil. In the current study, we evaluated the microbial diversity in soil samples from ginger cultivation with disease incidences of >50% (from the relatively sick sample) and 10% (from the relatively healthy sample). Illumine-based sequencing was used to identify the 16S and ITS genes in the bacterial and fungal species,respectively. The healthy soil sample included considerably more bacterial and fungal OTUs than the unhealthy sample. Additionally, distinct bacterial and fungal species were found to predominate in each sample. The prevalent bacterial genera in the healthy sample were Rhodanobacter and Kaistobacter, whereas the dominating genera in the ill sample were Rhodoplanes and Brady rhizobium. In terms of fungi, the dominating genera in the healthy sample were Cladosporium, Cryptococcus, and Tetracladium, whereas the dominant genera in the unhealthy sample were Lecanicillium, Pochonia, and Rhodotorula. The fundamental knowledge of the microbial diversity in ginger soil can be used to clarify the relationships between ginger and microbes and perhaps choose appropriate rhizobacteria and bio control agents for ginger production.
