Functional Genomics of Root Development in Populus and Its Ecological Implications
Summary
This review summarises research on functional genes governing poplar root system development, covering transcriptome analysis, gene editing, and epigenetic approaches to understand how roots respond to drought, nutrient deficiency, and microbial interactions, with implications for afforestation and ecological restoration.
This study summarizes the research progress of functional genes in the development of poplar root systems, introduces some important genes and signaling pathways that control the shape, differentiation process and response to the external environment of roots, integrates many methods such as transcriptome analysis, gene editing and epigenetic research, and clarifies the response of poplar root systems to drought, nutrient deficiency and interaction with microorganisms It also explores how these root traits are regulated within the body and discusses the possible assistance they may bring in afforestation, ecological restoration and other aspects. This study aims to provide a theoretical basis and technical reference for the study of poplar root systems, and also hopes to lay the foundation for breeding new varieties that are more adapted to the environment and have better traits in the future.

Nanoplastic toxicity induces metabolic shifts in Populus × euramericana cv. '74/76' revealed by multi-omics analysis
Researchers used transcriptomic and metabolomic profiling to show that polystyrene nanoplastics accumulate in poplar tree roots, penetrate chloroplasts in leaves causing photosynthesis disruption, and trigger a metabolic shift from normal growth to defensive flavonoid production under severe exposure conditions.
Differences in Root Endophytic Bacterial Communities of Chinese Cork Oak (Quercus variabilis) Seedlings in Different Growth Years
Researchers used high-throughput sequencing to compare root endophytic bacterial communities in Chinese cork oak seedlings of different ages, finding that seedling age influences the composition and functional potential of root microbiomes in forest regeneration contexts.
Synthetic microbial communities derived from nanoplastic-reshaped root endophytes alleviate phytotoxicity in Populus × euramericana cv. '74/76'
Researchers assembled synthetic microbial communities from nanoplastic-enriched root endophytes to protect poplar trees from nanoplastic toxicity. The study found that inoculation with these engineered microbial communities significantly improved plant growth, reduced nanoplastic accumulation, and alleviated oxidative damage through complementary strategies including detoxification, enhanced energy storage, and antioxidant defense pathways.
The Role of Omics Technology in Evaluating Plastic Pollution’s Effects on Plants: A Comprehensive Review
This comprehensive review examines how omics technologies (genomics, proteomics, metabolomics, transcriptomics) are being applied to understand the molecular mechanisms by which micro- and nanoplastics damage plants, including oxidative stress, stunted growth, and disrupted soil microbiomes.
Responses of Physiological, Morphological and Anatomical Traits to Abiotic Stress in Woody Plants
This review examines how trees and woody plants respond to environmental stresses including drought, flooding, extreme temperatures, heavy metals, and microplastics. Microplastics in soil can disrupt water transport and nutrient uptake in trees, potentially affecting forest health and the broader ecosystem. The effects of combined stresses, such as microplastics plus drought, are not simply additive and need further study.
