“…Their use increased and by 2014 the world consumption of fungicides was of circa 14.7 billion US dollars (Maienfisch and Stevenson, 2015). However, the pressure on the discontinuation of fungicides is growing mainly due to: 1) considerable resistance to fungicides (Possiede et al, 2009); 2) fungicides and pesticides are generally considered concerning contaminants of water and soil causing environmental and health issues (Kaonga et al, 2017). These facts resulted on the decrease of the number of fungicides used in some countries (Zhang, 2018).…”

In order to address the ever-increasing problem of the world's population food needs, the optimization of farming crops yield, the combat of iron deficiency in plants (chlorosis) and the elimination/reduction of crop pathogens are of key challenges to solve. Traditional ways of solving these problems are either unpractical on a large scale (e.g. use of manure) or are not environmental friendly (e.g. application of iron-synthetic fertilizers or indiscriminate use of pesticides). Therefore, the search for greener substitutes, such as the application of siderophores of bacterial source or the use of plant-growth promoting bacteria (PGPB), is presented as a very promising alternative to enhance yield of crops and performance. However, the use of microorganisms is not a risk-free solution and the potential biohazards associated with the utilization of bacteria in agriculture should be considered. The present work gives a current overview of the main mechanisms associated with the use of bacteria in the promotion of plant growth. The potentiality of several bacterial genera (Azotobacter, Azospirillum, Bacillus, Pantoea, Pseudomonas and Rhizobium) regarding to siderophore production capacity and other plant growth-promoting properties are presented. In addition, the field performance of these bacteria genera as well as the biosafety aspects related with their use for agricultural proposes are reviewed and discussed.

“…These facts resulted on the decrease of the number of fungicides used in some countries (Zhang, 2018). For example, in Japan, recently, the trend of fungicide use has been declining (Kaonga et al, 2017). However, new developing economies may lead to a new surge in fungicide usage (Zhang, 2018).…”

“…Botrytis cinerea is difficult to control because it can infect using different strategies and use different hosts as its inoculum source because it can survive as mycelia, conidia, and/or sclerotia for long periods of time in crop residues and in the soil. Chemical fungicides are intensively used for its control; however, there is scientific evidence that highlights their detrimental effects on human health, the environment, and the economy [4,5]. Moreover, their effectiveness has been affected by the appearance of resistant strains [6].…”

Antifungal Activity of Beauveria bassiana Endophyte against Botrytis cinerea in Two Solanaceae Crops

Botrytis cinerea causes substantial losses in tomato and chili pepper crops worldwide. Endophytes have shown the potential for the biological control of diseases. The colonization ability of native endophyte strains of Beauveria bassiana and their antifungal effect against B. cinerea were evaluated in Solanaceae crops. Root drenching with B. bassiana was applied, and endophytic colonization capacity in roots, stems, and leaves was determined. The antagonistic activity was evaluated using in vitro dual culture and also plants by drenching the endophyte on the root and by pathogen inoculation in the leaves. Ten native strains were endophytes of tomato, and eight were endophytes of chili pepper. All strains showed significant in vitro antagonism against B. cinerea (30–36%). A high antifungal effect was observed, and strains RGM547 and RGM644 showed the lowest percentage of the surface affected by the pathogen. Native strains of B. bassiana colonized tomato and chili pepper tissues and provided important levels of antagonism against B. cinerea.

“…Some of the world's greatest famines and the resulting human suffering can be blamed on plant pathogenic fungi and fungi-like organisms (FLOs). Fungicides are primarily used on fruit and vegetable crops and approximately 97% of potato crops are treated with fungicides (Kaonga et al, 2018). The fungicides including Maneb, Mancozeb, cymoxanil, dimethomorph hexaconazole, iprodione, isoprothiolane and thia bendazole are sprayed on vegetables (Bentley et al, 2006;Stadlinger et al, 2018).…”

Globally, fungi and fungi-like organisms, with over 8,000 species, cause more plant diseases than any other group of plant pests. Chitinases possess an anti-fungal role in disease resistance. They represent the pathogen-related protein group that cleaves β-1,4-glycoside bond of chitin present in the cell wall of filamentous fungi by catalysing the hydrolytic cleavage. In this study, we have amplified 672 base pair (bp) coding regions of the plant chitinase gene of Hordeum vulgare, over-expressed in Eschercia coli (E. coli) host BL21 DE3 strain by 0.5mM Isopropyl β-D-1-thiogalactopyranoside (IPTG) induction. In western blotting, the recombinant chitinase protein transferred on nitrocellulose membrane was detected at 26 kDa with histidine-tagged antibody reactions. By applying the nickel charged sepharose column affinity chromatography method, a single purified band of recombinant chitinase protein was found at 26 kDa in SDS-PAGE. The purified recombinant chitinase protein during the agar well diffusion method inhibited the growth of three phytopathogenic fungi in a significant way; Alternaria alternate, Rhizoctonia solani and Fusarium oxysporum in qualitative in-vitro antifungal assays. The purified recombinant chitinase protein showed up to 82.6% reduction in A. alternate hyphal growth; 77% reduction of hyphal growth in Rhizoctonia solani and 78% reduction of Fusarium's hyphal growth in invitro quantitative antifungal assays, thus depicting a strong antifungal potential. Conclusively, plant derived chitinase genes are superior in protecting the crops from phytopathogenic fungi if cloned in a suitable plant vector and expressed.
