Figure 1. Genome-wide screening for genes involved in hydrogen sulfide production under MR condition. (a) Schematic screening strategy and hydrogen sulfide levels of total screening genes under regular and MR condition at 15 h after inoculation. The red diamond in the box plot indicates the value of the wild-type strain. The Venn diagram shows the number of mutants selected by 2 different statistical strategies. (b) Genetic network of the 168 selected genes from 2 analyses. The significantly enriched biological processes and involved genes are indicated.
