“…Cyanobacterial polysaccharides (POL) show higher disease resistance against B. cinerea when they are applied on the intact fruit (preharvest conditions when fruit is attached to the plant) rather than the fruit detached (postharvest conditions) from the plant (Zheng et al 2011;Feliziani et al 2015;Yao and Tian 2005). Polysaccharides are involved in elicitation as elicitors for development of local and systemic disease resistance and expression of defense enzyme synthesis, for example, chitinases and glucanases that are involved directly in antifungal responses (Paulert et al 2009;Reymond and Farmer 1998;Sharma et al 2014 (Roberti et al 2015(Roberti et al , 2016. In the recent past, fungi inhibitory ability of algal members has been reported by several workers (Righini et al 2018;Corato et al 2017;Khallil et al 2015;Ibraheem et al 2017).…”

Natural Bioactive Products in Sustainable Agriculture

Seeking solutions from nature for solving one and all problems is the age-old practice for mankind, and natural products are proved to be the most effective one for keeping up the balance of development as well as the "healthy, wealthy, and well" condition of mother nature. Fungal pathogens are proved to be a common and popular contaminant of agroecosystem that approximately causes 70-80% of total microbial crop loss. To meet the proper global increasing need of food products as a result of population explosion, managing agricultural system in an eco-friendly and profitable manner is the prime target; thus the word "sustainable agriculture" plays it part, and this package is highly effective when coupled with nature-derived fungicidal products that can minimize the event of fungal infections in agrarian ecosystem. Present study enlists the most common and effective natural products that might be of plant or microbial origin, their mode of action, day-by-day development of phytopathogenic resistance against the prevailing fungicides, and also their role in maintenance of sustainability of agricultural practices with special emphasis on their acceptance over the synthetic or chemical one. A large number of bioactive compounds ranging from direct plant (both cryptogams algae and moss and phanerogams)-derived natural extracts, essential oil of aromatic plants, and low-molecular-weight antimicrobial compounds known as phytoalexins to secondary metabolites that are both volatile and nonvolatile organic compounds of microbes (fungal and actinobacterial members) residing inside the host tissue, called endophyte, are widely used as agricultural bioweapons. The rhizospheric partners of plant, mycorrhizae, are also a prime agent of this chemical warfare and protect their green partners from fungal invaders and emphasize the concept of "sustainable agriculture." 132

“…Extracts obtained from algae and cyanobacteria may be considered a useful tool for disease control. Indeed, algae and cyanobacteria extracts showed activity against several plant pathogens [7,8,9,10,11,12,13]. Recent studies demonstrated that extracts from the two brown algae Laminaria digitata and Undaria pinnatifida and from the red one Porphyra umbilicalis inhibited both B. cinerea mycelial growth and spore germination [14].…”

“…Another extract from the brown alga Lessonia trabeculata displayed a protective effect against B. cinerea on tomato leaves [11]. Moreover, in horticultural plants algal and cyanobacterial extracts were capable of increasing the transcription and the activity of defense-related enzymes involved in the control of fungal pathogens [9,15,16,17].…”

Different Antifungal Activity of Anabaena sp., Ecklonia sp., and Jania sp. against Botrytis cinerea

et al. 2019

Water extracts and polysaccharides from Anabaena sp., Ecklonia sp., and Jania sp. were tested for their activity against the fungal plant pathogen Botrytis cinerea. Water extracts at 2.5, 5.0, and 10.0 mg/mL inhibited B. cinerea growth in vitro. Antifungal activity of polysaccharides obtained by N-cetylpyridinium bromide precipitation in water extracts was evaluated in vitro and in vitro at 0.5, 2.0, and 3.5 mg/mL. These concentrations were tested against fungal colony growth, spore germination, colony forming units (CFUs), CFU growth, and on strawberry fruits against B. cinerea infection with pre- and post-harvest application. In in vitro experiments, polysaccharides from Anabaena sp. and from Ecklonia sp. inhibited B. cinerea colony growth, CFUs, and CFU growth, while those extracted from Jania sp. reduced only the pathogen spore germination. In in vitro experiments, all concentrations of polysaccharides from Anabaena sp., Ecklonia sp., and Jania sp. reduced both the strawberry fruits infected area and the pathogen sporulation in the pre-harvest treatment, suggesting that they might be good candidates as preventive products in crop protection.

Induction of defense enzymes and control of anthracnose in cucumber by Corymbia citriodora aqueous extract

et al. 2018

View full text Add to dashboard Cite

Secondary compounds of medicinal plants can activate defense mechanisms in plants against pathogens. The aqueous extract (AE) of Corymbia citriodora has shown that activity, but there is scarce information about the involved mechanisms of action. Therefore, this study aimed to evaluate the effect of AE on the induction of defense enzymes and protection of cucumber from Colletotrichum lagenarium. Thus, the AE, autoclaved or not, was evaluated for its capability of protecting and inducing peroxidases, polyphenoloxidases, chitinases and β-1.3-glucanases, and phenylalanine ammonia-lyase. Distilled water and acibenzolar-S-methyl (50 mg a.i. L-1) were used as controls. The effect of AE at the concentrations of 1, 5, 10, 15 and 20% was also evaluated, as well as its local and systemic effect, and the effect of one or two applications. Pathogen inoculation or sample collection for determination of enzyme activity was performed at 72 hours after treatments. The AE reduced the severity of C. lagenarium and induced peroxidases and β-1.3-glucanases by 37.6, 67.2 and 122.7%, respectively. There was a reduction in the disease severity and an increase in peroxidases from the concentration of 5% AE. The latter showed only local effect and greater reduction in severity when two applications were performed. These results suggest the effect of AE in inducing resistance in cucumber and inducing peroxidases and β-1.3-glucanases.
