Shielding of Photosynthetic Apparatus by Consortia of Bacterial Endophytes in Tomato Plants Suffering From Fusarium Wilt

Fusarium oxysporum is one of the most damaging plant pathogens causing wilt in many plants leading to serious economic loss. The fungus colonizes xylem, which leads resistance water flow thereby affecting rate photosynthesis. present study focuses on selection bacterial endophytes isolated from tomato and evaluating their potential antagonize vivo . results obtained indicated that two endophytic isolates, namely Pseudomonas fluorescens BUMD5 Bacillus velezensis BUMD9, could act as efficient biocontrol agents (BCAs) they inhibited growth pathogen by 67.2 69.1%, respectively, vitro Both isolates were found produce hydrolytic enzymes chitinase protease. They also produced siderophore hydrogen cyanide (HCN). consortia both significantly reduced infection percentage about 67% a 3-fold decrease disease severity was observed compared control. treatment infected with these potent beneficial improving overall photosynthetic performance index (PI). Thus, treated exhibited better despite being pathogen.
