MetabolomicsIntegrated multi-omics analysis reveals the molecular basis underlying heterografting mediated regulation of longhorn beetle resistance in poplar scions and growth inhibition in poplar 107 scions
Grafting improves plant traits and productivity, but the mechanisms underlying rootstock regulation of scion traits remain unclear. In this study, reciprocal grafting was performed between Populus × euramericana cv. 'Neva' (poplar 107) and Populus tomentosa 'Yixian' (P. tomentosa). Physiological, gr...

MetabolomicsA fungal endophyte alters poplar leaf chemistry, deters insect feeding and shapes insect community assembly
The endophytic fungi of certain grasses and herbaceous plants provide anti-herbivore defense compounds, thus living in mutualistic interaction with their hosts. Still, there is little information on such cooperation for tree-associated endophytes. We investigate the influence of the endophytic fungu...

MetabolomicsInteraction between rhizobacterial community and host root metabolism influences poplar salt tolerance

Poplar seedlings were cultivated in saline soil with low salt concentrations for 120 days, after which root tissues were harvested for untargeted metabolomic analysis. For each genotype, roots of three to four seedlings were pooled to form one biological replicate, with four biological replicates...

MetabolomicsEcological effects of water and fertilizer coupling on poplar planting soil

While irrigation and fertilization are basic cultivation practices in poplar plantations on a global scale, the impact of these practices on the environment is not well understood. Here, we demonstrate that water-urea coupling and water-compound fertilizer coupling differentially impact soil ecos...

MetabolomicsEffect of NAC154 transcription factor overexpression on the field grown poplar stem wood metabolome
Several xylem-associated regulatory genes have been identified that control processes associated with wood formation in poplar. Prominent among these are the NAC domain transcription factors (NACs). We evaluated the putative involvement of Populus NAC154, a co-ortholog of the Arabidopsis gene SND2, ...

MetabolomicsLong-term application of biogas slurry altered the microbial community structure and metabolites in rhizosphere soil of poplar plantations

We aim to investigate the changes in the structure and function of rhizosphere microorganisms when different concentrations of biogas slurry are applied to the rhizosphere of poplar trees. By measuring the variations and types of rhizosphere metabolites, we can determine the microbial changes and...

MetabolomicsPb Stress and Ectomycorrhizas: Strong Protective Proteomic Responses in Poplar Roots Inoculated with Paxillus involutus Isolate and Characterized by Low Root Colonization Intensity
The commonly observed increased heavy metal tolerance of ectomycorrhized plants is usually linked with the protective role of the fungal hyphae covering colonized plant root tips. However, the molecular tolerance mechanisms in heavy metal stressed low-colonized ectormyocrrhizal plants characterized ...

MetabolomicsMulti-omics analysis of xylem sap uncovers dynamic modulation of poplar defenses by ammonium and nitrate
Xylem sap is the major transport route for nutrients from roots to shoots. In the present study, we investigated how variations in nitrogen (N) nutrition affected the metabolome and proteome of xylem sap and the growth of the xylem endophyte Brennaria salicis, and we also report transcriptional re-w...

TranscriptomicsRNA-seq of five Populus x canescens (Grey poplar) organs/tissues during periodic or chronic drought-heat stress treatment and after recovery in comparison to untreated controls
Simulating predicted future climate conditions, stress response and stress-related memory after one week of recovery were transcriptionally characterised in young and old leaves, phloem-bark, developing xylem and roots of 3-month-old Grey poplar plants that had undergone three weeks of stress or wer...

TranscriptomicsSeasonal differences in expression patterns of LMPC-enriched poplar wood rays
Ray cells were enriched from wood samples of poplar (Populus x canescens) by LMPC and transcripts monitored by poplar whole genome microarrays. Results provided insight into molecular processes during the transition from dormancy to flowering in early spring in contrast to the active growth phase in...
