“…Therefore, we directly attribute the higher ROSscavenging enzyme activity in infected samples to the higher ROS radical activities in infected samples. Ascorbate peroxidase activity has been shown to increase in plants infected by pathogens such as apricot, wheat and mung bean (Hern andez et al 2001;Chen et al 2015;Farahani and Taghavi 2016a). Similarly, GPX has also been observed to increase in plants that are infected such as sunflowers infected by downy mildew (Herbette et al 2003).…”

Fusarium infection of bananas is a global problem that threatens the production of bananas. This study looks at the effects of the infection upon the reactive oxygen species (ROS) system, as well as the induced antioxidant properties in the roots, stems, leaves and fruits. Results show that there is a greater amount of damage in infected tissue samples as opposed to non‐infected. The damage was observed to be higher in the root samples. ROS assays were divided into two classes: ROS assays and ROS‐scavenging assays. Of the ROS assays, lipoxygenase was observed to be higher in the infected samples, while peroxidase (POD) and polyphenol oxidase (PPO) were significantly higher in infected stem, leaf and fruit samples. Among root samples, there was no significant difference in POD activity and PPO was lower in infected samples. Induction of ROS is important for the hypersensitive response (HR) to function properly. The ROS‐scavenging enzymes, namely ascorbate peroxidase, guaiacol peroxidase and superoxide dismutase, exhibited higher levels in the infected tissue. This is most likely to counter the build‐up of the ROS enzymes and to prevent further cell death. The increase in ROS‐scavenging assays also correlates with higher antioxidant properties as antioxidants play a critical role in regulating the HR free radicals.

To investigate the adaptive mechanism of wheat under high light, osmotic stress, and salt stress, redox regulation, and photosynthesis were compared. Under high light, the activities of antioxidant enzymes, except for catalase, significantly increased and then decreased after 1 and 3 h, respectively. Under osmotic stress, antioxidant enzyme activities significantly increased and subsequently declined. Except for superoxide dismutase, salt stress induced a significant increase in all the antioxidant enzyme activities. A significant decrease of D1 protein by high light and osmotic stress, strong photophosphorylation of D1 and D2 under high light and salt stress were observed, while all the stresses induced upregulation of PsbS protein. Eight stress-associated genes (TaMYB73,

QTL Mapping of Wheat Stripe Rust Resistance in Relation to Epidermal Flavonoids Measured Using a Leaf‐Clip, Optical Sensor

Epidermal flavonoids have long been suggested as targets for selection in stress‐adaptive crop breeding, but routine selection is neither practicable nor cost effective because of the time‐consuming process involved in phenotyping. In this research, we found that the content of epidermal flavonoids, measured using the chlorophyll fluorescence excitation ratio method, was inversely related to stripe rust (Puccinia striiformis f. sp. tritici [Pst]) response in wheat (Triticum aestivum L.). We investigated the genetic basis by conducting quantitative trait locus (QTL) mapping with a 9K single nucleotide polymorphism (SNP) array in a cross of ‘Drysdale’ × ‘Waagan’ segregating for adult‐plant stripe rust resistance. Data from 3 yr of field experimental trials were analyzed, and heritability estimates for epidermal flavonoids varied from 0.16 to 0.47 across the experiment‐years. In contrast, heritability for stripe rust response varied from 0.79 to 0.84. Eleven QTL were identified for epidermal flavonoids, with a major locus on chromosome 4D, explaining between 19.5 and 47.3% of the phenotypic variation across years. Thirteen QTL were identified for stripe rust response, with the major locus explaining 68% of the phenotypic variation. Quantitative trait loci associated with epidermal flavonoids and stripe rust response were colocated on chromosomes 2B and 3B, but other genetic loci detected for the respective traits were independent. The study has established a genetic basis for epidermal flavonoids measured using the nondestructive, leaf‐clip sensor in wheat, which will encourage further research on the possible exploitation of the compound by breeding and selection.
