Salinity is one of the most important abiotic stress factors that negatively affect plant growth and development. In contrast, fusaric acid (FA), a mycotoxin produced by Fusarium and Giberella fungal genera, has biological and metabolic effects in various plants. In this study, it was aimed to investigate the protective effect of externally applied FA (0.1 nM) against the damage caused by salt (0.15 M NaCl) stress in onion (Allium cepa L.) plant. Salt stress resulted in an increase in the chromosomal aberrations (CAs) and micronucleus (MN) frequency, a decrease in the mitotic index (MI), fresh weight, root number, germination percentage, and root length. It promoted CAs such as irregular mitosis, bilobulated nuclei, chromosome loss, bridge, unequal seperation of chromosome, vagrant chromosome and polar slip in root meristem cells. In addition, salt stress caused a enhancement in free proline (PR), catalase (CAT), superoxide dismutase (SOD) and malondialdehyde (MDA) contents in the roots of onion plant. Moreover, it revealed damage and changes that include the accumulation of some chemical substances such as proline and sugars in epidermis and cortex layer cells, epidermal cell injury, flattening of the cell nucleus, wall thickening in cortex cells, necrotic areas and indistinct transmission tissue in the anatomical structure of onion roots. On the other hand, FA application promoted bulb germination and mitotic activity, strengthened the antioxidant defense system, and reduced chromosome and anatomical structure damages. In conclusion; it has been revealed that exogenous FA application may have a positive effect on increasing the resistance of onion plants to salt stress.

“…For example, Dendrobium sonia 28 strain showed a higher mortality rate and growth reduction upon FA exposure (Dehgahi et al 2016 ). Similarly, a high dose of FA exposure inhibited root growth and development of maize seedlings (Spss and Oliveira 2009 ). Likewise, the cell suspension cultures of Nicotiana tabacum treated with 100 µM of FA phytotoxin showed dilation of the endoplasmic reticulum and damage to cisternae (Jiao et al 2013 ).…”

“…FA also causes plant diseases such as fusarium wilt, which reduces the yield of many agricultural crops (Singh et al 2017 ). The toxicity of FA has been documented in many plant species such as tomato (Singh et al 2017 ), potato (Sapko et al 2011 ), cucumber (Wang et al 2015 ), watermelon (Wu et al 2007 ), banana (Fung et al 2019 ), date palm (Bouizgarne et al 2004 ), Arabidopsis (Bouizgarne et al 2006a ), maize (Spss and Oliveira 2009 ), cotton (Stipanovic et al 2011 ), tobacco (Jiao et al 2014 ), wheat (Li et al 2021 ), barley (Liu et al 2016 ), saffron (Samadi and Shahsavan Behboodi 2006 ), wax gourd (Wang et al 2021 ), chihuahua flower (Antić et al 2020 ), faba bean (Li et al 2021 ), castor bean (Pavlovkin et al 2004 ), cape gooseberry (Mendoza-Vargas et al 2021 ), sword lily (Nosir et al 2011 ) and hemp broomrape (Bouizgarne et al 2006b ). In plants, FA induces oxidative stress, chloroplast and mitochondrial dysfunction, lipid peroxidation, protein damage and DNA fragmentation (Jiao et al 2014 ; Iqbal et al 2021a ) (Fig.…”

Fusaric acid (FA) is one of the most harmful phytotoxins produced in various plant–pathogen interactions. Fusarium species produce FA as a secondary metabolite, which can infect many agronomic crops at all stages of development from seed to fruit, and FA production can further compromise plant survival because of its phytotoxic effects. FA exposure in plant species adversely affects plant growth, development and crop yield. FA exposure in plants leads to the generation of reactive oxygen species (ROS), which cause cellular damage and ultimately cell death. Therefore, FA-induced ROS accumulation in plants has been a topic of interest for many researchers to understand the plant–pathogen interactions and plant defence responses. In this study, we reviewed the FA-mediated oxidative stress and ROS-induced defence responses of antioxidants, as well as hormonal signalling in plants. The effects of FA phytotoxicity on lipid peroxidation, physiological changes and ultrastructural changes at cellular and subcellular levels were reported. Additionally, DNA damage, cell death and adverse effects on photosynthesis have been explained. Some possible approaches to overcome the harmful effects of FA in plants were also discussed. It is concluded that FA-induced ROS affect the enzymatic and non-enzymatic antioxidant system regulated by phytohormones. The effects of FA are also associated with other photosynthetic, ultrastructural and genotoxic modifications in plants. Graphical abstract
