dsRNA Uptake in Plant Pests and Pathogens: Insights into RNAi-Based Insect and Fungal Control Technology

Plants, Journal Year: 2020, Volume and Issue: 9(12), P. 1780 - 1780

Published: Dec. 16, 2020

Efforts to develop more environmentally friendly alternatives traditional broad-spectrum pesticides in agriculture have recently turned RNA interference (RNAi) technology. With the built-in, sequence-specific knockdown of gene targets following delivery double-stranded (dsRNA), RNAi offers promise controlling pests and pathogens without adversely affecting non-target species. Significant advances efficacy this technology been observed a wide range species, including many insect fungal pathogens. Two different dsRNA application methods are being developed. First, host induced silencing (HIGS) harnesses production through thoughtful precise engineering transgenic plants second, spray (SIGS) that uses surface applications topically applied molecule. Regardless method, one aspect is critical success ability target organism internalize take advantage cellular machinery. The efficiency uptake mechanisms varies across some negligible, rendering them effectively resistant new generation control technologies. If RNAi-based be used widely, it critically important understand underpinning uptake. Understanding will also provide insight into design formulation dsRNAs for improved clues development potential resistance these

Habitability of low-lying socio-ecological systems under a changing climate

Climatic Change, Journal Year: 2024, Volume and Issue: 177(1)

Published: Jan. 1, 2024

Abstract Climate change will push the planet worryingly close to its boundaries, across all latitudes and levels of development. One question therefore is extent which climate does (and will) severely affect societies’ livelihoods, health, well-being, cultures. This paper discusses “severe risks” concept developed under Working Group II’s contribution Fifth Sixth Assessment Reports Intergovernmental Panel on Change (IPCC, AR5, AR6). Focusing low-lying coastal socio-ecological systems (LCS) acknowledging that attempts define “severe” risk have been problematic at level global syntheses, we argue for a more place- people-based framing relating “habitability changing climate.” We summarize habitability in terms five pillars: land, freshwater, food, settlement infrastructure, economic subsistence activities; acknowledge social cultural factors (including perceptions, values, governance arrangements, human agency, power structures) as critical underlying rather than separate pillars. further develop examine future health three “hotspot” archetypes (arctic coasts, atoll islands, densely populated urban areas). Building IPCC AR6 severe risks, discuss key parameters describing risks LCS: point irreversibility changes, physical thresholds , cascading effects various dimensions. also highlight variability conditions both between within each them. Further work should consist refining case study find right balance capturing context-specificities through real-world local studies commonalities derived from generic archetypes. In addition, there need identify appropriate methods assess thus habitability.

The Bengal Water Machine: Quantified freshwater capture in Bangladesh

Science, Journal Year: 2022, Volume and Issue: 377(6612), P. 1315 - 1319

Published: Sept. 15, 2022

Global food security depends on the sustainability of irrigated agriculture. Rising groundwater withdrawals from seasonally humid, alluvial plains across tropical Asia have enabled dry-season rice cultivation. This pumpage increases available subsurface storage that under favorable conditions amplifies replenishment during subsequent monsoon. We empirically quantified this nature-based solution to seasonal freshwater capture described as "Bengal Water Machine," revealing its potential and limitations. On basis a million piezometric observations 465 monitoring wells, we show collective operation ~16 smallholder farmers in Bengal Basin Bangladesh 1988 2018 has induced cumulative volumetrically (75 90 cubic kilometers) is equivalent twice reservoir capacity Three Gorges Dam.

The relationship between ecosystem services and human modification displays decoupling across global delta systems

Communications Earth & Environment, Journal Year: 2022, Volume and Issue: 3(1)

Published: April 28, 2022

Abstract The ties between a society and its local ecosystem can decouple as societies develop replace services such food or water regulation via trade technology. River deltas have developed into important, yet threatened, urban, agricultural industrial centres. Here, we use global spatial datasets to explore how 49 respond four human modification indicators, e.g. population density, across 235 large deltas. We formed bundles of statistically correlated examined if their relationship with changed. Decoupling all robust service from at least one indicator was indicated in 34% deltas, while 53% displayed decoupling for bundle. Food-related increased modification, the other declined. Our findings suggest two developmental pathways deltas: coupled systems risking irreversible biodiversity loss; decoupled urban centres externalising impact growing demands.

Role of Polyamines in the Response to Salt Stress of Tomato

Plants, Journal Year: 2023, Volume and Issue: 12(9), P. 1855 - 1855

Published: April 30, 2023

Plants irrigated with saline solutions undergo osmotic and oxidative stresses, which affect their growth, photosynthetic activity yield. Therefore, the use of water for irrigation, in addition to increasing soil salinity, is one major threats crop productivity worldwide. Plant tolerance stressful conditions can be improved using different strategies, i.e., seed priming acclimation, elicit morphological biochemical responses overcome stress. In this work, we evaluated combined effect acclimation on salt stress response a tomato cultivar (Solanum lycopersicum L.), very sensitive salinity. Chemical seeds was performed by treating polyamines (PAs): 2.5 mM putrescine (PUT), spermine (SPM) spermidine (SPD). Germinated primed non-primed (controls) were sown non-saline soil. The consisted irrigating seedlings 2 weeks tap water, followed irrigation 4 weeks. At end growth period, morphological, physiological parameters determined. positive effects treatments evident, when plants compared non-primed, grown under same conditions. Priming PAs stress, reduced negative salinity membrane integrity, increased pigments, proline enzymatic non-enzymatic antioxidant all salt-exposed plants. These results may open new perspectives strategies increase species, such as tomato.
