“…Through the SA pathway, the increase in the expression of PR1 and β-1,3-glucanase genes was determined to be effective against B. cinerea in the leaves of strawberry and tomato plants. This defensive response against B. cinerea is a consequence of the root inoculation of B. amyloliquefaciens and B. thuringiensis, respectively, which activates a priming before the attack of the pathogen [62,68]. Similarly, the inoculation of B. velezensis in pepper roots is capable of causing hydrogen peroxide accumulation and superoxide dismutase (SOD), catalase (CAT), and peroxidase (POD) activity in leaves [69].…”

Botrytis cinerea is a polyphagous necrotrophic fungus and is the causal agent of grey mold diseases in more than 1400 different hosts. This fungus causes serious economic losses in both preharvest and post-harvest—mainly in grape, strawberry, and tomato crops—and is the second most important pathogen worldwide, to our knowledge. Beneficial bacteria and fungi are efficient biocontrol agents against B. cinerea through direct mechanisms, such as parasitism, antibiosis, and competition, but also indirectly through the activation of systemic plant resistance. The interaction between plants and these microorganisms can lead to the development of defensive responses in distant plant organs, which are highly effective against foliar, flower, and fruit pathogens, such as B. cinerea. This review aimed to explore the systemic plant defense responses against B. cinerea by compiling all cases reported (to the best of our knowledge) on the use of beneficial bacteria and fungi for agriculture, a subject not yet specifically addressed.

“…Many Bacillus species have been demonstrated to be effective against a broad range of plant pathogens via producing various antimicrobial compounds (lipopeptides, antibiotics, and enzymes), competing for growth factors, such as space and nutrients, inducing systemic resistance in host plants and promoting plant growth . Several Bacillus species have been documented to be capable of increasing the control capacity against gray mold disease by inhibiting the growth of B. cinerea directly or inducing plant resistance against the pathogen. − However, there is a growing demand for additional biological control agents for gray mold caused by B. cinerea , and the underlying biocontrol mechanisms remain to be elucidated.…”

Botrytis cinerea is an important fungal pathogen that causes gray mold disease in plants. Previously, Bacillus velezensis TCS001 live culture presented broad-spectrum antifungal activity against various plant pathogenic fungi and oomycetes, particularly B. cinerea. Here, the bioactivity of lipopeptides produced by TCS001 against B. cinerea was investigated. The IC 50 values of the crude lipopeptide extract (CLE) from TCS001 to suppress mycelial growth and conidial germination were 14.20 and 49.39 mg/L, respectively. SEM and TEM imaging revealed that CLE caused morphological deformities and ultrastructural changes in the mycelium. Transcriptomic analyses combined with ΔBcpsd mutant construction demonstrated that the CLE could confer antifungal activity via suppressing Bcpsd expression in the pathogen. In addition, the CLE activated the plant immune system by increasing the content of defense-related enzymes and the expression of marker genes in immunity signaling pathways in cucumber plants. Therefore, TCS001 CLE could be potentially developed into biopesticides for the biocontrol of gray mold disease.
