“…The activity of GOPX and CAT was significantly stimulated in N-infested plants in comparison with control ones. Similar results were observed earlier in A. thaliana and Lycopersicon esculentum plants infected with nematodes (Labudda et al 2018;Khanna et al 2019). In the present results, elevated activities of GOPX and CAT were not reflected in the reduced content of H 2 O 2 .…”

Key message Defence responses of cyst nematode and/or wheat curl mite infested barley engage the altered reactive oxygen species production, antioxidant machinery, carbon dioxide assimilation and photosynthesis efficiency. Abstract The primary aim of this study was to determine how barley responds to two pests infesting separately or at once; thus barley was inoculated with Heterodera filipjevi (Madzhidov) Stelter (cereal cyst nematode; CCN) and Aceria tosichella Keifer (wheat curl mite; WCM). To verify hypothesis about the involvement of redox metabolism and photosynthesis in barley defence responses, biochemical, photosynthesis efficiency and chlorophyll a fluorescence measurements as well as transmission electron microscopy were implemented. Inoculation with WCM (apart from or with CCN) brought about a significant suppression in the efficiency of electron transport outside photosystem II reaction centres. This limitation was an effect of diminished pool of rapidly reducing plastoquinone and decreased total electron carriers. Infestation with WCM (apart from or with CCN) also significantly restricted the electron transport on the photosystem I acceptor side, therefore produced reactive oxygen species oxidized lipids in cells of WCM and double infested plants and proteins in cells of WCM-infested plants. The level of hydrogen peroxide was significantly decreased in double infested plants because of glutathione–ascorbate cycle involvement. The inhibition of nitrosoglutathione reductase promoted the accumulation of S-nitrosoglutathione increasing antioxidant capacity in cells of double infested plants. Moreover, enhanced arginase activity in WCM-infested plants could stimulate synthesis of polyamines participating in plant antioxidant response. Infestation with WCM (apart from or with CCN) significantly reduced the efficiency of carbon dioxide assimilation by barley leaves, whereas infection only with CCN expanded photosynthesis efficiency. These were accompanied with the ultrastructural changes in chloroplasts during CCN and WCM infestation.

“…Based on obtained results, it was stated that the H 2 O 2 neutralizing in the leaves of N plants was largely depended on APX activity. This was in line with our earlier studies showing increased APX activity in shoots of A. thaliana plants infected with H. schachtii (Labudda et al 2018) and with studies by Khanna et al (2019) also showing higher activity of APX in tomato leaves as a result of infestation by M. incognita. In addition, increased APX activity in Cd plants relative to the control plants found Fig.…”

“…Different letters indicate means which are significantly different at p < 0.05 according to one-way analysis of variance and a posthoc Tukey's test Labudda et al (2018) showed that superoxide and hydrogen peroxide increased level occurred in shoots of Arabidopsis thaliana plants infected with the beet cyst nematode Heterodera schachtii. In addition, Khanna et al (2019) presented enhanced production of these ROS in shoots of Lycopersicon esculentum plants infested by root-knot nematode Meloidogyne incognita. Furthermore, an abundance of published results showed that Cd stimulated the production of ROS in many plant species (Chmielowska-Bąk et al 2014).…”

Efficient antioxidant defence systems of spring barley in response to stress induced jointly by the cyst nematode parasitism and cadmium exposure

Aims This research aimed to establish how Hordeum vulgare responds to abiotic and biotic stress affecting in tandem. Methods Plants were inoculated with Heterodera filipjevi and treated with cadmium (Cd) concentration (5 μM) that can occur in the cultivated soil. To verify the hypothesis about participation of increased antioxidative defence in H. vulgare under stress, biochemical and microscopic methods were implemented. Results The amount of superoxide anions and hydrogen peroxide was diminished in plants that were both nematode-inoculated and cadmium-treated. Superoxide anions were rendered harmless by increased activity of superoxide dismutase, and H2O2 was scavenged via Foyer-Halliwell-Asada pathway. The unique enhanced antioxidant capacity of double stressed plants was also linked with the accumulation of S-nitrosoglutathione as nitrosoglutathione reductase activity was inhibited. Furthermore, stimulated activity of arginase in these plants could promote polyamine synthesis and indirectly enhance non-enzymatic antioxidant mechanism. Results indicate that different antioxidants operating together significantly restricted oxidation of lipids and proteins, thus the integrity of cell membranes and protein functions were maintained. Conclusions The ROS deactivation machinery in barley leaves showed an unusual response during stress induced by H. filipjevi infection and cadmium treatment. Plants could induce a multi-component model of stress response, to detoxify Cd ions and efficiently repair stress damage.

“…Bertrand and Anthony (2008) In this study, we analysed coffee genotype performance under similar soil water availability. In this condition, differences in the Ψpd of the coffee genotypes reflect the differences in their ability to uptake and/or transport water from the roots to the leaves (Silva (Khanna et al, 2019). For all the genotypes, the net carbon assimilation rate (A) and stomatal conductance (gs) were suppressed beginning on the eighth day after the irrigation was interrupted.…”

Climate change greatly influences coffee production, especially in areas infested with plant‐parasitic nematodes. In this study, coffee genotypes showed differences in their morphological and physiological characteristics when subjected to a water deficit and parasitism by Meloidogyne paranaensis. The cultivar IPR 100 had the largest superficial and volumetric root system area, even when parasitized. The two progenies (MG 0179‐1 and MG 0179‐3) and the cultivar Catuaí IAC 62 had a similar surface area (p < .05) when parasitized. However, the root surface area and volume of MG 0179‐3 increased by 96% and 400%, respectively, when parasitized by M. paranaensis. On the other hand, Catuaí IAC 62 had a 31% reduction in root surface area. Catuai 62 and IPR 100 showed higher sensitivity to drought when parasitized because of the increased photochemical sensitivity and reduction in photochemical quenching. In MG 0179‐1 and MG 0179‐3, an increase in non‐photochemical quenching occurred in response to stress, indicating that these progenies use a photochemical response to protect photosystem II. In this work, MG 0179‐3, which is resistant to M. paranaensis, was remarkable because, interestingly, the infestation caused an increase in its root surface area. In addition, MG 0179‐3 had relatively good photochemical performance under water deficit and M. paranaensis parasitism.
