Increasing the number of stressors reduces soil ecosystem services worldwide

Nature Climate Change, Год журнала: 2023, Номер 13(5), С. 478 - 483

Опубликована: Март 16, 2023

Increasing the number of environmental stressors could decrease ecosystem functioning in soils. Yet this relationship has never been globally assessed outside laboratory experiments. Here, using two independent global standardized field surveys, and a range natural human factors, we test between exceeding different critical thresholds maintenance multiple services across biomes. Our analysis shows that, stressors, from medium levels (>50%), negatively significantly correlates with impacts on services, that crossing high-level threshold (over 75% maximum observed levels), reduces soil biodiversity globally. The >75% was consistently seen as an important predictor therefore improving prediction functioning. findings highlight need to reduce dimensionality footprint ecosystems conserve function.

Stress combinations and their interactions in plants database: a one‐stop resource on combined stress responses in plants

The Plant Journal, Год журнала: 2023, Номер 116(4), С. 1097 - 1117

Опубликована: Окт. 12, 2023

SUMMARY We have developed a compendium and interactive platform, named Stress Combinations their Interactions in Plants Database (SCIPDb; http://www.nipgr.ac.in/scipdb.php ), which offers information on morpho‐physio‐biochemical (phenome) molecular (transcriptome metabolome) responses of plants to different stress combinations. SCIPDb is plant informatics hub for data mining phenome, transcriptome, trait‐gene ontology, data‐driven research advancing mechanistic understanding combined biology. analyzed global phenome from 939 studies delineate the effects various combinations yield major crops found that was substantially affected under abiotic–abiotic stresses. Transcriptome datasets 36 hosted identified novel genes, whose roles not been earlier established stress. Integretome analysis drought–heat pinpointed carbohydrate, amino acid, energy metabolism pathways as crucial metabolic, proteomic, transcriptional components tolerance These examples illustrate application identifying genes involved tolerance. Further, we showed this database candidate drought pathogen To our knowledge, only publicly available platform offering stress‐specific omics big visualization tools, such an scrollbar, matrix, radial tree, distribution map, meta‐phenome analysis, search, BLAST, transcript expression pattern table, Manhattan plot, co‐expression network. tools facilitate better mechanisms underlying

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 altering exposure potential biodiversity. also address responses plants increased temporal variability radiation, change (e.g. drought, temperature) crops, driving breakdown organic matter from dead plant material (i.e. litter) biocides (pesticides herbicides).

Abstract Concepts regarding the operation of ascorbate–glutathione cycle and associated water/water in processing metabolically generated hydrogen peroxide other forms reactive oxygen species (ROS) are well established literature. However, our knowledge functions these cycles their component enzymes continues to grow evolve. Recent insights include participation intrinsic environmental developmental signalling pathways that regulate plant growth, development, defence. In addition ROS processing, two not only support ascorbate glutathione, they also have ‘moonlighting’ functions. They subject post-translational modifications an extensive interactome, particularly with proteins. this assessment current knowledge, we highlight central position network cellular redox systems underpin energy-sensitive communication within different compartments integrate pathways.

The impact of multifactorial stress combination on plants, crops, and ecosystems: how should we prepare for what comes next?

The Plant Journal, Год журнала: 2023, Номер 117(6), С. 1800 - 1814

Опубликована: Ноя. 23, 2023

The complexity of environmental conditions encountered by plants in the field, or nature, is gradually increasing due to anthropogenic activities that promote global warming, climate change, and increased levels pollutants. While past it seemed sufficient study how acclimate one even two different stresses affecting them simultaneously, complex developing on our planet necessitate a new approach studying stress plants: Acclimation multiple occurring concurrently consecutively (termed, multifactorial combination [MFSC]). In an initial plant response MFSC, conducted with Arabidopsis thaliana seedlings subjected MFSC six abiotic stresses, was found increase number simultaneously impacting plant, growth survival declined, if effects each involved such minimal insignificant. three recent studies, crop plants, have similar commercial rice cultivar, maize hybrid, tomato, soybean, causing significant reductions growth, biomass, physiological parameters, and/or yield traits. As are worsening, as well becoming more complex, addressing its agriculture ecosystems worldwide becomes high priority. this review, we address crops, agriculture, worldwide, highlight potential avenues enhance resilience crops MFSC.

‘Against all floods’: plant adaptation to flooding stress and combined abiotic stresses

The Plant Journal, Год журнала: 2024, Номер 117(6), С. 1836 - 1855

Опубликована: Янв. 13, 2024

SUMMARY Current climate change brings with it a higher frequency of environmental stresses, which occur in combination rather than individually leading to massive crop losses worldwide. In addition to, for example, drought stress (low water availability), also flooding (excessive water) can threaten the plant, causing, among others, an energy crisis due hypoxia, is responded by extensive transcriptional, metabolic and growth‐related adaptations. While signalling during relatively well understood, at least model plants, molecular mechanisms combinatorial responses, simultaneously salinity, temperature heavy metal or sequentially stress, remain elusive. This represents significant gap knowledge fact that dually stressed plants often show unique responses multiple levels not observed under single stress. this review, we (i) consider possible effects combinations from theoretical point view, (ii) summarize current state on signal transduction (iii) describe plant adaptation combined four other abiotic stresses (iv) propose components (hypoxia) based their reported dual roles stresses. way, more future emphasis may be placed deciphering adaptation, thereby potentially stimulating development tools improve resilience towards multi‐stress scenarios.
