Soil Bacterial Community May Offer Solutions for Ginger Cultivation

Abstract

Pythium myriotylum and Ralstonia solanacearum cause soft rot disease and bacterial wilt, respectively. In this study, we used the bacterial 16S V3–V4 hypervariable region of the 16S rRNA region to investigate microbe compositions in healthy and diseased ginger soil and find out the influence of the well-known biocontrol agent B. velezensis and the fungicide Etridiazole on soil microbes and ginger productivity.

Comparative Analyses of Soil Bacterial Colonies of Two Types of Chinese Ginger after a Major Flood Disaster

“…Huaijiang (HJ) ginger, Zhangliang ginger, Panghai (PH) ginger, and Shannong ginger are some of the well-known Chinese ginger varieties. Ginger in Chinese medicines has been used to dispel cold, dispel sweat, promote hair growth, and strengthen the stomach ( 3 , 4 ). In addition, ginger is an important flavor seasoning for Chinese cuisine, with the role of removing fishy fragrance, showing its great economic and medicinal value ( 3 , 4 ).…”

The growth and development of the ginger plant require several nutrients (including nitrogen, phosphorus, and potassium), which are circulated by microorganisms as decomposers ( 3 , 5 ).…”

However, along with beneficial microorganisms, soil also comprises some pathogenic microorganisms, which inhibit crop growth ( 3 , 6 ). Thus, it is important to characterize the community structure of ginger soil microorganisms ( 2 , 5 ).…”

“…In soil microbial sequencing, a bacterial genome’s 16S rRNA gene fragment is first amplified and sequenced, followed by studying the colony type and microorganism structure through bioinformatic analyses ( 3 , 5 , 7 , 8 ). Recently, with the development of research and technology, second-generation high-throughput sequencing (NGS) technology has emerged, which is a modification of the traditional Sanger sequencing ( 9 – 11 ).…”
