“…Not only biocontrol strains are able to induce plant defence mechanisms against pathogenic attacks, but also PGPR (plant growth promoting rhizobacteria. In this regard, it was shown that strains of Bacillus subtilis and B. pumilus can enhance seed germination of Vigna unguiculata, offering protection against blackeye cowpea mosaic strain of Bean Common Mosaic Virus to the cowpea plants [29]. Similar results were described in tobacco plants treated with PGPR.…”

“…In the case of viruses residing inside the embryo (such as CMV and BCMV), seed treatments with chemicals are often not effective and, in addition, resistance genes are present only in some genotypes. Several studies dealing with seed treatment with Plant Growth-Promoting Bacteria (PGPR) evidenced the PGPR’s effectiveness in improving the health of young plants and, consequently, their resistance to the early viral infections in V. unguiculata [ 56 ].…”

During the last three years, more than 300 landraces belonging to different plant species have been the main focus of an Italian valorization research project (AgroBiodiversità Campana, ABC) aiming at analyzing, recovering, preserving, and collecting local biodiversity. In this context, phytosanitary investigation plays a key role in identifying potential threats to the preservation of healthy seeds in gene banks and the successful cultivation of landraces. The surveillance carried out in this study, in addition to highlighting the expected presence of common species-specific pathogens such as Ascochyta pisi in peas, Ascochyta fabae in broad beans, and Macrophomina phaseolina, Xanthomonas axonopodis pv. phaseoli, and Xanthomonas fuscans subsp. fuscans in beans, pointed to the presence of novel microorganisms never detected before in the seeds of some hosts (Apiospora arundinis in common beans or Sclerotinia sclerotiorum and Stemphylium vesicarium in broad beans). These novel seedborne pathogens were fully characterized by (i) studying their morphology, (ii) identifying them by molecular methods, and (iii) studying their impact on adult crop plants. For the first time, this study provides key information about three novel seedborne pathogens that can be used to correctly diagnose their presence in seed lots, helping prevent the outbreaks of new diseases in the field.

“…As for plant disease management, the induction of plant resistance by PGPR has become a trend in recent years. Although a large number of studies have focused on PGPR-induced resistance to various bacterial and fungal pathogens (Van Loon et al, 1998;Kloepper et al, 2004), only a few studies have investigated application of PGPR strains for plant viral disease control under greenhouse and/or field conditions (Raupach et al, 1996;DeMeyer et al, 1999;Udaya Shankar et al, 2009;Wang et al, 2009). These studies are mostly associated with bacteria from the genus Bacillus that are in contact with plants to control TMV or CMV via ISR and other mechanisms (Kloepper et al, 2004;Zhou et al, 2008).…”

Enterobacter asburiae BQ9, a plant-growth-promoting rhizobacterium, was shown to promote tomato plant growth and induce resistance to Tomato yellow leaf curl virus (TYLCV) under greenhouse conditions. Compared with mock-treated tomato plants, plants that were pretreated with BQ9 had increased fresh mass and significantly reduced disease severity and 52% biocontrol efficacy was achieved 30 days after inoculation. The expression of defense-related genes PR1a and PR1b and the H 2 O 2 burst were quickly induced in BQ9 pretreated plants. Antioxidase activity analysis showed that the activities of phenylalanine ammonia lyase, peroxidase, catalase, and superoxide dismutase increased significantly in BQ9 pretreated plants. Our results suggest that the plant-growth-promoting rhizobacterium BQ9 induced a priming of the plant defense responses to TYLCV by increasing the expression of defense response genes, and the induced resistance was mechanistically connected to the expression of antioxidant enzymes and the production of H 2 O 2 .

Rhizobacteria‐mediated resistance against the blackeye cowpea mosaic strain of bean common mosaic virus in cowpea (Vigna unguiculata)

Abstract: PGPR strains were effective in protecting cowpea plants against BCMV under both screen-house and field conditions by inducing resistance against the virus. Thus, it is proposed that PGPR strains, particularly GBO3, could be potential inducers against BCMV and growth enhancers in cowpea.
