This analysis evaluates the response of wheat to fusarium oxysporum infection, revealing significant biochemical changes and oxidative stress implications.
Abiotic and biotic stresses trigger a substantial decline in crop quality and productivity. Responses to stress are crucial components of environmental homeostasis in plants. In this communication, the physiological and biochemical response of wheat (Triticum aestivum) sensitivity to F. oxysporum infection was evaluated. According to physiological study, the fresh weight (FW), dry weight (DW), and relative water content (RWC) were decreased in Fusarium infected leaves and root tissues when compared with control tissues. The photosynthetic pigments chlorophyll (Chla and Chl b), and carotenoid (Car) were decreased in Fusarium infected tissues as compared to control tissues. Moreover, the disease rating (DR) was increased in Fusarium infected tissues indicating the high production of reactive oxygen species (ROS). An enhanced level of hydrogen peroxide (H2O2) was observed in the Fusarium infected tissues as compared to control tissues. In addition, the reducing sugar (RS) was enhanced, while the non-reducing sugar (NS) and total sugar (TS) contents were decreased in the Fusarium infected tissues as compared to control tissues. The activity of antioxidant enzymes such as superoxide dismutase (SOD), and catalase (CAT) was higher in Fusarium infected tissues as compared to control tissues to minimize the Fusarium induced oxidative stress.
