🍽️Faba bean represents an important food crop, green manure and fodder. Faba bean is particularly susceptible to the hazards of continuous cropping, leading to increases in soil-borne disease and poor growth.
🌱One of these diseases is Fusarium wilt, caused by Fusarium oxysporum f. sp. fabae (FOF) infection. It has been found that FOF inoculation stimulates the secretion of various substances, including phenolic and organic acids, sugars, and amino acids, from the plant roots. To date, studies have mostly investigated the influence of F. oxysporum on faba bean plants under the stress of F. oxysporum alone, although it has been reported that pathogens in the soil are affected by plant allelopathy.
☠️Autotoxicity represents a specific form of allelopathy whereby autotoxic compounds are released into the environment through plant residues in the soil, the aboveground parts of the plant, and plant root exudates. These substances harm not only the development and growth of the plant itself but also other plants. Studies have reported that autotoxicity can create an environment conducive to the growth of pathogens, thereby promoting their proliferation.
➡️The authors used faba bean monocropping (M) and intercropping with wheat (I), with stress treatments of Fusarium oxysporum f. sp. fabae (FOF) alone (F) and combined with cinnamic acid (F + C), to analyze seedling growth, defence-related enzymes, levels of resistance-associated substances, and protein expression profiles in roots.
