Plant growth-promoting (PGP) capacity of the 200 bacteria isolates from the grapevine rhizosphere to produce ammonia, indole acetic acid, ACC deaminase, and siderophore, to solubilize phosphate, and to fix atmospheric nitrogen. (A) Distribution of the PGP activities according to the genera previously identified using MALDI-TOF MS. When a PGP activity was detected, it was considered as an occurrence within the distribution graph (i.e., one isolate can have several PGP activities). (B) The eight most promising isolates identified using sequencing, and selected for in vitro growth promotion assays on Lepidium sativum and 1103P plantlets. (+++) indicates that the isolate was the most effective within the considered PGP function. (++) indicates that the isolate was among the top 50% most effective. (+) indicates that the isolate was among the 50% least effective. (-) indicates a non-effective isolate in the corresponding PGP function.
