The role of exogenous nitric oxide (NO) application in alleviating drought stress responses by enhancing the antioxidant activities in plants is well established for several species. However, none of the studies reported its role in protecting the watermelon genotypes from drought stress. In this study, we aimed to observe the effect of NO application on the physiological and biochemical responses of the two watermelon (Citrullus lanatus var. lanatus) genotypes grown under drought stress conditions by treating the plants with 15% polyethylene glycol 6000 (PEG 6000) and 100 µM sodium nitroprusside (SNP), which is a NO donor in Hoagland solution. Among the two genotypes, one genotype, KAR 98 was drought tolerant; while another, KAR 147 was drought sensitive. Drought stress showed a decrease in the growth parameters of both the genotypes; however, as expected it was higher in the susceptible genotype, KAR 147. NO application could not prevent the reductions in the growth parameters; however, it reduced the increment in malondialdehyde (MDA) content caused by the drought stress in both watermelon genotypes. Moreover, while drought stress condition reduced the ascorbate peroxidase (APX), catalase (CAT), glutathione reductase (GR), and peroxidase (POX) activities in both genotypes, NO + PEG application increased the APX activity in the tolerant genotype, KAR 98. Though the obtained results does not show the direct involvement of NO in increasing drought tolerance of watermelon plants, the increase in the APX antioxidant enzyme activity on NO application under drought stress confirmed its role in protecting the watermelon genotypes from the oxidative damage caused by the drought stress. Moreover, it can be concluded that the effect of NO application on watermelons' responses towards drought stress condition may vary according to the specific genotypes. As to date none of the studies reported the effect of NO application on the antioxidant activity of watermelon genotypes under drought stress, the present study may provide information about the mechanisms that can be focused to improve drought stress tolerance of watermelon genotypes.

“…Table 6 The effect of branched broomrape infestation and biological control agents on the MDA content (µmol g − 1 FW) In cucumber studies, the MDA content increased in all cucumber genotypes as a result of P. aegyptiaca infection compared to that in the control (Faradonbeh et al 2020;Faradonbeh et al 2021). This study revealed that the MDA content generally increased in the broomrape-infected plants compared to that in the uninfected plants.…”

Tomato (Solanum lycopersicum L.), one of the world's most produced and consumed vegetables, belongs to the Solanaceae family. Branched broomrape [Phelipanche ramosa (L.) Pomel; Syn: Orobanche ramosa L.] parasitizes many cultivated plants, especially tomatoes. The parasitic weeds, for which there is no effective control method, cause serious yield and quality losses in their host crops. In this study, two different mycorrhiza (AMF) species, Funneliformis mosseae, and a commercial product, Endo Roots Soluble (ERS), along with Trichoderma harzianum T22, two different plant growth-promoting rhizobacteria (PGPR) isolates (Pseudomonas caspiana V30G2 and Bacillus velezensis V40K2), were applied to tomatoes. Additionally, a commercial product, Plant Success Great White Premium Mycorrhiza, and their combinations were used to determine the changes occurring in both the plants and the broomrape. This study investigated the number of tubercles, the levels of several oxidative stress enzymes (CAT, catalase, SOD, superoxide dismutase, and APX, ascorbate peroxidase), the level of lipid peroxidation (MDA, malondialdehyde), and the total phenolic and antioxidant contents of tomato plants infected and not infected with broomrape. Compared to the control group, the treatments were found to prevent tubercule formation at rates ranging from 60 to 72.7%. Broomrape infection caused oxidative stress in the tomatoes; the CAT and MDA contents in the broomrape-contaminated plants were greater than those in the noncontaminated plants. The results revealed that some microorganisms and biological preparations applied to tomatoes responded differently to broomrape stress through enzymatic and nonenzymatic antioxidant activities.
