Editorial: Plants and environmental threats

Résumé

Plants and environmental threatsIn the face of escalating environmental challenges that threaten the delicate balance of our planet, the Research Topic titled "Plants and Environmental Threats" emerges as a beacon of hope and a pivotal contribution to the global discourse on ecological sustainability.This Research Topic of manuscripts transcends the boundaries of conventional academic compilations, embodying a confluence of innovative research, forward-thinking strategies, and an unwavering commitment to environmental stewardship.Within its pages, these studies weave a rich tapestry of knowledge that illuminates the indispensable role of plants and microbes in mitigating environmental threats, charting a course towards a sustainable future that hinges on our understanding of and collaboration with the natural world.As the foundation of most ecosystems on Earth, plants provide essential services including food production, carbon sequestration, and oxygen generation.However, escalating environmental perils pose growing risks to plant life across the globe.Recent scientific research illuminates both the emerging threats to plants as well as some promising biotechnology solutions.By examining key examples, we can understand the nuanced interplay between plants and their surrounding environments.A study focusing on the yeast Kre6 in the marine alga Pleurochrysis haptonemofera provided new insights into the biochemical pathways involved in algal cell wall synthesis (Inukai et al.).The researchers found that the Kre6 homolog in P. haptonemofera, dubbed PhTGS, plays an essential role in assembling the β-glucans that provide structural integrity to algal cell walls.This study sheds light on the composition and formation of cell walls, which provide protection against environmental stressors.As climate change drives ocean warming and acidification, understanding algal cell wall biochemistry could enable cultivation of genetically improved strains with enhanced resilience to protect fragile marine ecosystems.Soil and water contamination from potentially toxic elements (PTEs) like lead, arsenic, and cadmium represents a massive environmental problem worldwide, but some innovative bioremediation techniques show promise in sustainably treating contamination.Furthermore, a review outlined how applying biochar, a substance produced by pyrolysis of organic waste biomass, can effectively immobilize PTEs in polluted soils (Zhang et al.).Biochar provides abundant adsorption sites via its porous structure and charged surfaces, which chemically bind free metal ions in soils.This reduces their mobility and bioavailability, thereby mitigating contamination of groundwater, uptake in food crops, and accumulation in
