Expression profiling for genes involved in Vitamin B6 (VitB6) biosynthesis was undertaken to delineate the involvement of  de novo  and salvage pathway induced by  Bacillus subtilis  CBR05 against,  Xanthomonas campestris  pv.  vesicatoria  in tomato. Pyridoxine biosynthesis (PDX) genes such as  PDX1.2  and  PDX1.3 , were found to be overexpressed significantly at 72 hpi in  B. subtilis  and pyridoxine inoculated plants. Most significant upregulation was observed in the transcript profile of  PDX1.3 , which showed more than 12- fold increase in expression. Unfortunately, salt sensitive overlay4 ( SOS4 ) profiling showed irregular expression which corroborates that  SOS4  role in VitB6 biosynthesis needs further studies for deciphering a clear notion about their role in tomato. Antioxidant enzymes i.e., superoxide dismutase, catalase, polyphenol oxidase, and peroxidase activities clearly demonstrate escalation till 48 hpi and gets reduced in 72 hpi. Pot trials also confirm that  B. subtilis  compared to pyridoxine supplementation alone show plant disease resistance and elongated roots. The present study confirms that  B. subtilis , as a versatile agent in eliciting induced systemic resistance regulated by  de novo  pathway as a model for plant defense against  X. campestris  pv.  vesicatoria  substantiated by VitB6 biosynthesis. Nevertheless, the study is preliminary and needs further evidence for affirming this phenomenon.
