Exposure of plants to mild chronic stress can cause induction specific, stress-induced morphogenic responses (SIMRs). These are characterized by a blockage cell division in the main meristematic tissues, an inhibition elongation and redirected outgrowth lateral organs. Key elements ontogenesis this phenotype appear be stress-affected gradients reactive oxygen species (ROS), antioxidants, auxin ethylene. present at organismal level, but integrated on cellular affecting division, and/or...
Abstract Epidemiological studies have revealed an inverse association between the consumption of fruit, vegetables, and herbs risk both cancer cardiovascular disease. This protective effect is mostly due to secondary metabolites present in plant tissues. During last decade, it has become increasingly clear that UV-B radiation important regulator metabolism. Low, ecologically-relevant levels trigger distinct changes accumulation of, among others, phenolic compounds, carotenoids...
Abstract This assessment by the Environmental Effects Assessment Panel (EEAP) of United Nations Environment Programme (UNEP) provides latest scientific update since our most recent comprehensive (Photochemical and Photobiological Sciences, 2019, 18, 595–828). The interactive effects between stratospheric ozone layer, solar ultraviolet (UV) radiation, climate change are presented within framework Montreal Protocol Sustainable Development Goals. We address how these global environmental...
The aquatic Lemnaceae family, commonly called duckweed, comprises some of the smallest and fastest growing angiosperms known on Earth. Their tiny size, rapid growth by clonal propagation, facile uptake labeled compounds from media were attractive features that made them a well-known model for plant biology 1950 to 1990. Interest in duckweed has steadily regained momentum over past decade, driven part need identify alternative plants traditional agricultural crops can help tackle urgent...
Abstract Microplastics have become ubiquitous in all environments. Yet, their environmental fate is still largely unknown. Plastic fragmentation a key component of plastic degradation, which mostly caused by abiotic processes over prolonged time scales. Here, it shown that the freshwater amphipod Gammarus duebeni can rapidly fragment polyethylene microplastics, resulting formation differently shaped and sized fragments, including nanoplastics. Fragments comprised 65.7% observed microplastic...
Abstract The Environmental Effects Assessment Panel of the Montreal Protocol under United Nations Environment Programme evaluates effects on environment and human health that arise from changes in stratospheric ozone layer concomitant variations ultraviolet (UV) radiation at Earth’s surface. current update is based scientific advances have accumulated since our last assessment (Photochem Photobiol Sci 20(1):1–67, 2021). We also discuss how climate change affects depletion radiation, change....
Terrestrial organisms and ecosystems are being exposed to new rapidly changing combinations of solar UV radiation other environmental factors because ongoing changes in stratospheric ozone climate. In this Quadrennial Assessment, we examine the interactive effects ozone, climate on terrestrial biogeochemical cycles context Montreal Protocol. We specifically assess organisms, agriculture food supply, biodiversity, ecosystem services feedbacks system. Emphasis is placed role extreme events...
Plants raised under field conditions are acclimated to ambient levels of solar UV‐B radiation. Morphogenic responses part the acclimation process and have been hypothesized contribute UV avoidance. induced morphogenic include inhibition hypocotyl stem elongation, leaf curling, thickening increased axillary branching. So far, neither photosensory nor signal transduction mechanism involved in mediated morphogenesis has identified. The combination classical photobiological techniques...
Plant stress responses are a key factor in steering the development of cells, tissues, and organs. However, stress-induced signal transduction cascades that control localized growth cell size/differentiation not well understood. It is reported here oxidative stress, exerted by paraquat or alloxan, induced proliferation intact seedlings, isolated root segments, at single level. Analysis mitotic activity revealed enhances auxin-dependent cycle reactivation. Based on similarities between plant,...
Abstract We have studied the mechanism of UV protection in two duckweed species (Lemnaceae) by exploiting sensitivity photosystem II as an situ sensor for radiation stress. A UV-tolerantSpirodela punctata G.F.W. Meyer ecotype had significantly higher indole-3-acetic acid (IAA) levels than a UV-sensitive ecotype. Parallel work on Lemna gibbamutants suggested that tolerance is linked to IAA degradation rather free or conjugated IAA. This linkage consistent with role class III phenolic...
• Ultraviolet B (UV-B) acclimation comprises complex and poorly understood changes in plant metabolism. The effects of chronic ecologically relevant UV-B dose rates on Arabidopsis thaliana were determined. process was studied by measuring radiation morphology, physiology, biochemistry gene expression. Chronic did not affect photosynthesis or the expression stress responsive genes, which indicated that UV-acclimated plants stressed. UV-induced morphological acclimated included decreased...
