“…However, several negative points have emerged regarding these chemicals, including environmental impact, the emergence of resistant bacteria, and harmful effects on human and animal health. Consequently, numerous studies have searched for more efficient and sustainable alternatives to copper, and some products have been cited, such as Acibenzolar-S-methyl (ASM) [ 44 ], bacteriophages [ 45 ], antibiotic streptomycin produced by Bacillus amyloliquefaciens strain FZB24 [ 42 ], and inducers of systemic acquired resistance (SAR) [ 46 ].…”

As agricultural practices become more sustainable, adopting more sustainable practices will become even more relevant. Searching for alternatives to chemical compounds has been the focus of numerous studies, and bacteriocins are tools with intrinsic biotechnological potential for controlling plant diseases. We continued to explore the biotechnological activity of the bacteriocin Gluconacin from Gluconacetobacter diazotrophicus, PAL5 strain, by investigating this protein’s antagonism against important tomato phytopathogens and demonstrating its effectiveness in reducing bacterial spots caused by Xanthomonas perforans. In addition to this pathogen, the bacteriocin Gluconacin demonstrated bactericidal activity in vitro against Ralstonia solanacearum and Pseudomonas syringae pv. tomato, agents that cause bacterial wilt and bacterial spots, respectively. Bacterial spot control tests showed that Gluconacin reduced disease severity by more than 66%, highlighting the biotechnological value of this peptide in ecologically correct formulations.

“…In plants, heat stress leads to the denaturation of proteins by promoting the degradation of cellular proteins. It also affects the membrane’s permeability as plants’ cell walls disintegrate under high heat stress conditions [ 115 ]. Many findings indicated that heat or cold stress impacted the expression level of most flavonoid-related transcripts.…”

Cytochrome P450s (CYPs) are the most prominent family of enzymes involved in NADPH- and O2-dependent hydroxylation processes throughout all spheres of life. CYPs are crucial for the detoxification of xenobiotics in plants, insects, and other organisms. In addition to performing this function, CYPs serve as flexible catalysts and are essential for producing secondary metabolites, antioxidants, and phytohormones in higher plants. Numerous biotic and abiotic stresses frequently affect the growth and development of plants. They cause a dramatic decrease in crop yield and a deterioration in crop quality. Plants protect themselves against these stresses through different mechanisms, which are accomplished by the active participation of CYPs in several biosynthetic and detoxifying pathways. There are immense potentialities for using CYPs as a candidate for developing agricultural crop species resistant to biotic and abiotic stressors. This review provides an overview of the plant CYP families and their functions to plant secondary metabolite production and defense against different biotic and abiotic stresses.

“…Several studies demonstrated that copper applications fail to offer significant protection to yield losses caused by BST [19,[29][30][31][32]; however, this type of treatment is still widely used by farmers to deal with the disease. It is unclear if applying these treatments specifically for the management of bacterial spot is economically profitable for the farmer.…”

Managing Bacterial Spot of Tomato: Do Chemical Controls Pay Off?

et al. 2023

Bacterial spot of tomato (BST) is a disease that severely afflicts tomato crops, especially in geographic areas such as the Southeastern U.S., where the environmental conditions favor rapid disease development. Farmers usually use chemical treatments such as copper–mancozeb mixtures and acibenzolar-S-methyl, among other methods, to manage BST. However, these chemical treatments generally fail to improve marketable yields, thus raising the question of whether the BST treatments are economical. We evaluated the efficacy and profitability of bactericide treatments consisting of copper-mancozeb, acibenzolar-S-methyl, and streptomycin, as well as three inoculation levels of Xanthomonas euvesicatoria pv. perforans, on the management of BST in Florida. Across three separate field trials, BST severity was inversely correlated with marketable tomato yields; however, bactericide treatments provided no statistical improvement in marketable yields. By accounting for yield and the BST treatment costs, our profitability analysis showed that the BST treatments did not pay off economically; the net returns of these treatments were statistically equivalent to the untreated controls.
