[[File:Gene Regulatory Network for Initiation of Sporulation in Bacillus subtilis.png|thumb|Fig2. Gene Regulatory Network for Initiation of Sporulation in Bacillus subtilis]]
In the table below, the term ''''Activators'''' refers to genes/proteins that ultimately result in initiation of sporulation and ''''Repressors'''' refers to the ones that inhibit this initiation of sporulation.
{| class="wikitable sortable"
|-
! Activators !! Regulation !! Repressors !! Regulation
|-
| KinA || Transfers phosphate to the Spo0F || Sda || Blocks autophosphorylation of KinA
|-
| KinB || Transfers phosphate to the Spo0F || KipI || Blocks autophosphorylation of KinA
|-
| Spo0A || Activates several key sporulation-specific genes || Spo0A || Negatively controls transcription of abrB
|-
| Spo0H (σH) || Activates phrE gene || ComA || Activates competence
|-
| Spo0B || Phosphotransferase initiation || SinR || Negative regulation of kinB
|-
| Spo0F || Phosphotransferase initiation || RapA, RapB, RapE, and RapH || Dephosphorylation of Spo0F~P
|-
| ComA || Activates phrA || Spo0E, YisI, and YnzD || Dephosphorylation of Spo0A~P
|-
| SinI || Antagonist of SinR || GTP-bound CodY || Inhibits rapA-phrA
|-
| KipA || Inhibits kipI gene || AbrB || Encodes a repressor of spo0H
|-
| PhrA || Suppresses dephosphorylation activity of RapA || Hpr || Overexpression inhibits sporulation
|-
| PhrE || Inhibits RapE || DnaA || Over expression of Sda
|-
| PhrH || Inhibits RapH || ||
