Abstract
Pitchers are the unique structures of carnivorous plants used for the trapping of insects and other small invertebrates. The digestion of captured prey here is assisted by the bacteria, which have been associated with pitchers. These bacterial communities can therefore expect to have a variety of plant beneficial functions. In this study, the bacterial isolate NhPBG1 from the pitcher of Nepenthes hamblack was screened for activity against Pythium aphanidermatum, Rhizoctonia solani, Fusarium oxysporum, and Colletotrichum accutatum and was found to have the inhibitory activity towards all the tested phytopathogens. Interestingly, the isolate was found to have hyper-inhibitory effect against P. aphanidermatum. Further to this, the isolate was also shown to be positive for plant beneficial traits such as indole-3-acetic acid (IAA) and ammonia production, phosphate, potassium and zinc solubilization, nitrogen fixation, and 1-aminocyclopropane-1-carboxylate (ACC) deaminase activity. BLAST analysis of the 16S rDNA sequence of NhPBG1 has identified it as Paraburkholderia sp. Also, the Zingiber officinale rhizome pre-treated with NhPBG1 was found to get protected from P. aphanidermatum induced infection, whereas the control showed sympt...Continue Reading
