  • the poor interaction of [protein|DC3449D5F195E5C2E9E14FEC95396C8F1FDF73B4|SigH] with the [SW|RNA polymerase] is responsible for the poor [SW|sporulation] at high salinity, this phenotype can be partially suppressed by specific mutations in [protein|DC3449D5F195E5C2E9E14FEC95396C8F1FDF73B4|SigH] [Pubmed|26712348]
