“…Inhibition of the supply of essential ions required for seedlingbiomass accumulation could be one of the reasons for the reduction in growth and biomass. Similar studies on growth parameters have also reported reduced growth and biomass accumulation in various plant species in response to Cd stress [24,25]. In the present study, the inclusion ofVA in the growth medium under Cd stress conditions prevented the suppression of biomass accumulation by Cd in rice seedlings.…”

“…In the present study, the inclusion ofVA in the growth medium under Cd stress conditions prevented the suppression of biomass accumulation by Cd in rice seedlings. Previous reports have suggested that LMWOAs are capable of increasing growth and biomass under abiotic stresses, including Cd toxicity [24,25], indicating that they can alleviate the abiotic stress responses induced by metal/metalloids and allow greater tolerance to pollutants such as Cd.…”

Cadmium (Cd) is a toxic heavy metal that enters the human food chain from the soil via plants. Increased Cd uptake and translocation in plants alters metabolism andreduces crop production. Maintaining crop yield therefore requires both soil remediation andenhanced plant tolerance to Cd. In this study, we investigated the effects of vanillic acid (VA) on Cd accumulation and Cd stress tolerance in rice (Oryza sativa L. cv. BRRI dhan54). Thirteen-day-old rice seedlings treated with CdCl2 (1.0 and 2.0 mM) for 72 h showed reduced growth, biomass accumulation, and water and photosynthetic pigment contents, as well as increased signs of oxidative stress (elevated levels of malondialdehyde, hydrogen peroxide, methylglyoxal, and lipoxygenase) and downregulated antioxidant and glyoxalase systems. Cadmium-induced changes in leaf relative turgidity, photosynthetic pigment content, ascorbate pool size, and glutathione content were suppressed by VA under both mild and severe Cd toxicity stress. The supplementation of VA under Cd stress conditions also increased antioxidant and glyoxylase enzyme activity. Vanillic acid also increased phytochelatin content and the biological accumulation factor, biological accumulation co-efficient, and Cd translocation factor. Vanillic acid, therefore appears to enhance Cd stress tolerance by increasing metal chelation and sequestration, by upregulating antioxidant defense and glyoxalase systems, and by facilitating nutrient homeostasis.

“…All translocation factor values were found to be less than 1. The TF values of barnyard grass were found to be obviously decreased with the increase of Cd in the soil, which may be due to limited root-to-shoot transport when internal Cd concentration was high, which was similar to the previously reported results of cadmium accumulation in sunflower (Helianthus annuus L.) plants [26].…”

“…The staining was terminated by immersion of the leaves in hot water and then in warm 90% ethanol until they were decolorized, except for the deep brown polymerization product produced by DAB in the presence of H 2 O 2 . In our previous study using quantitative analysis and visualisation of H 2 O 2 in leaves, we found that the uneven distribution of this compound within the leaf lamella may distort its quantitative analysis and, in consequence, can give quite different results even for the same leaf (Hawrylak-Nowak et al, 2015). Because the preliminary studies have shown very heterogeneous accumulation of this compound S. lapponum leaves attacked by insects, in this study the accumulation and location of H 2 O 2 were assessed only visually and the most representative objects were photographed.…”

Abstract:Since the 1950s, a significant decrease in the population numbers of Salix lapponum L. has been observed in Poland, particularly in the Polesie Lubelskie region. One of the most important threats comes from the biotic environment including interactions at the trophic level. An unidentified issue was the occurrence and importance of phytophagous insects inhabiting S. lapponum in terms of real threats to growth and development as well as specific plant reactions to herbivores. The aim of the study was to recognize the occurrence of phytophagous insects inhabiting S. lapponum, i.e. an endangered species, and estimation of physiological changes caused by the herbivorous species feeding. The field study was conducted in a locality of S. lapponum population in the peat bog near Bikcze Lake (Polesie Lubelskie Region) in 2014-2015. In each growing season from the end of April to September, 100 stems of S. lapponum shoots with similar length were examined once a month. Selected parameters of chlorophyll a fluorescence were measured and the accumulation of H 2 O 2 was visually detected in leaves collected from the control plants and from those attacked by herbivores using the 3',3-diaminobenzidine (DAB) method. We found the presence of 8 phytophagous insect species from 4 orders (Coleoptera, Diptera, Hemiptera and Lepidoptera) on S. lapponum. Most of the shoots were inhabited by Lochmea caprea, Aphrophora salicina and Aphis farinosa. On the basis of the measurements of chlorophyll a fluorescence and H 2 O 2 accumulation under phytophagous insects feeding, we have demonstrated that S. lapponum was able to maintain photosynthesis under insect attack and that the accumulation of H 2 O 2 in leaf blades indicates local rather than systemic stress response to herbivore feeding. Phytophagous insects feeding caused relatively weak disruptions to host plant physiology and S. lapponum is able to maintain photosynthetic efficiency under insect attack. Variation in plant traits influence host plant selection and performance of herbivorous insects. Comparative studies are needed to assess the species composition and population numbers of insects occurring on plants from other S. lapponum populations. Detailed knowledge of the biotic factors affecting the occurrence of S. lapponum would facilitate establishment of the form of its conservation.
