Role of endophytic Penicillium species and Pseudomonas monteilii in inducing the systemic resistance in okra against root rotting fungi and their effect on some physiochemical properties of okra fruit

Aims The efficacy of three isolates of endophytic Penicillium species that have shown significant suppressive effect on root rotting fungi in our previous study were further evaluated in pots and field plot experiments for their effect on root diseases of okra, induction of systemic resistance and physiochemical properties of okra fruit. Methods and Results Aqueous suspensions of endophytic Penicillium and Pseudomonas monteilii were applied in pots and field plots using okra as test plant. Data on the fungal infection of roots, plant growth, plant resistance markers like polyphenol, salicylic acid and antioxidant status of plant were determined. These isolates significantly suppressed root diseases and induced systemic resistance via increasing level of resistance markers, polyphenol and salicylic acid besides improving antioxidant activity of Penicillium and P. monteilii‐treated plants as compared to control plants. GC‐MS analysis of n‐hexane extract of mycelium of P. nigricans revealed the presence of 15 different volatile compounds. Conclusions Endophytic Penicillium and P. monteilii have potential against root‐infecting fungi of okra and can improve plant growth and yield. Significance and Impact of the Study Endophytic Penicillium species and P. monteilii can suppress root rotting fungi by direct mechanism or induction of systemic resistance in plants.

“…However, some endophytes are predominant in speci c hosts and some are rare 31 . In this study, some endophytic fungi isolated are also known as plant pathogens like Fusarium sp., and Macrophomina phaseolina that attack on a wide range of economically important plants 22 . However, Talaromyces isolated in this study are the perfect stage of Penicillium known to possess biocontrol potential 32 .…”

Several reports revealed that endophytic fungi have great influence on host plants, as they promote plant growth and minimize disease severity caused by various pathogens. In this study, endophytic fungi isolated from healthy plants were identified as Aspergillus terreus, Curvularia lanata, C. hawaiiensis, Macrophomina phaseolina, Fusarium solani, Talaromyces assiutensis and T. trachyspermus were evaluated for antimicrobial activity, using dual-culture plate assay and agar disc diffusion method. They have shown significant activity against root rot pathogens, Macrophomina phaseolina, Rhizoctonia solani, Fusarium solani and F.oxysporum. Talaromyces assiutensis and T. trachyspermus were selected for further study, since other fungi are well known plant pathogens or environmental contaminants. They were applied in pots and field plot experiments using sunflower as test plant. There efficacy was also compared with endophytic Cephalosporium sp., and Chaetomium sp. Talaromyces spp., significantly suppressed root rotting fungi and improved plant biomass. They ameliorated production of plant defense biochemical markers (polyphenolic content and salicylic acid) and antioxidant potential of treated plants. GC-MS profiling of n- hexane fraction of T. trachyspermus yielded several new compounds from this source. Endophytic fungi associated with healthy plants have great potential to suppress root rotting fungi and stimulate production of plant’s defense biochemical markers.

“…Considerable amount of food is gone in post-harvest (Faiz et al, 2020). Moreover, the fungi and nematodes are also posing a serious threat to our crops (Parveen et al, 2020). Fungi is considered to be among the imperative pathogens of plants resulting in huge losses (Gonzalez et al, 2011;Hamon et al, 2011).…”

The major global concern of the developing countries is to fulfill the basic need of food to mankind as more than one-third of the food is lost due to various kinds of diseases and many other effects like postharvest loss by different fungi. The danger of post-harvest disease influences the way most horticultural crops are handled. Hence, the proper identification of the causal pathogen is important before appropriate treatment can be made to control the pathogens. Therefore, In the present study, Alternaria alternata, Alternaria, Rhizopus, Mucor, Aspergillus niger, Aspergillus flavus, Cladosporium, Botrytis cinerea, Fusarium moniliforme, Drechslera, Penicillium, and Geotrichum candidum were identified among various vegetables including potato, carrot, okra, eggplant, turnip, cucumber, round gourd, cauliflower, and chilli. These losses result in about a 30% reduction in the yield of these vegetables. By reducing the post-harvest losses, it could be possible to overcome the need of food as the world population is in dare need of research relating to crop sustainability.
