In the heart of Iraq, researchers are uncovering a potential game-changer in the fight against a devastating corn disease. Alyaa Abd Ali, a plant protection specialist from the University of Anbar, has been leading a team investigating the antifungal properties of local plant extracts against the Gibberella fujikuroi species complex, a group of fungi that causes damping-off disease in sweet corn. Their findings, published in the journal Scientific Reports (translated to “Scientific Reports” in English), could pave the way for more sustainable and effective fungicides in the agricultural sector.
Damping-off disease is a significant threat to sweet corn production worldwide, leading to reduced plant productivity and yield quality. The disease is caused by several Fusarium species, with F. verticillioides, F. fujikuroi, and F. oxysporum being the most aggressive strains, as identified by Ali’s team. These fungi not only hinder seed germination but also negatively impact other growth variables, posing a substantial challenge to farmers and the agricultural industry.
In their quest for a solution, Ali and her team turned to nature, exploring the antifungal potential of five wildly growing plant species native to Iraq. Using GC-MS analysis, they identified several bioactive compounds with promising antifungal properties. Among the most abundant compounds were 1-eicosanol, (Z)6,(Z)9-Pentadecadien-1-ol, and n-Hexadecanoic acid in Eruca vesicaria; Nonadecane in Oxalis pes-caprae; and Oxacyclotricosan-2-one and D-Homoandrostane in Ducrosia ismaelis.
The team’s in silico studies revealed that these compounds exhibited high binding free energy, low inhibition constant, and other favorable molecular docking and dynamic properties against three key fungal enzymes: GH10 xylanase, Plant-type chitinase inhibitors, and Sterol 14-alpha Demethylase. “These bioactive compounds can be listed as potential binders of these target proteins and could be used in designing new fungicides,” Ali explained, highlighting the commercial potential of their findings.
The implications of this research extend beyond the agricultural sector. As the world grapples with the challenges of climate change and food security, innovative solutions like these become increasingly vital. By harnessing the power of local plant extracts, farmers could potentially reduce their reliance on synthetic fungicides, leading to more sustainable and environmentally friendly farming practices.
Moreover, the discovery of these bioactive compounds opens up new avenues for research and development in the agrochemical industry. As Ali and her team continue to explore the antifungal properties of these compounds, they could pave the way for the development of novel fungicides that are not only effective but also eco-friendly.
In the words of Ali, “This research is just the beginning. We are excited about the potential of these bioactive compounds and the positive impact they could have on sweet corn production and the agricultural industry as a whole.” With their findings published in Scientific Reports, the stage is set for further exploration and collaboration, bringing us one step closer to a more sustainable and secure agricultural future.
