From: CrfP, a fratricide protein, contributes to natural transformation in Streptococcus suis
CrfP contributes to natural transformation in S. suis. A The deletion of crfP attenuated the transformation ability. B The qRT-PCR analysis showed that crfP does not play roles in competence-related processes. The transcription level did not change in the absence of the crfP gene. Unpaired two-tailed Student’s t test was used for the statistical analysis (*P < 0.05).
