Poplar is widely cultivated in China because of its strong ecological adaptability, fast growth, easy reproduction, and short rotation period. However, it suffers from severe threat from canker disease caused by Cytospora species. The present study revealed the presence of Cytospora species from ...

The allelochemical para-hydroxybenzoic acid (pHBA) is a serious threat to poplars subjected to continuous cropping. In order to elucidate the responsive mechanisms of plants to pHBA stress, we here performed tandem mass tag-based quantitative proteomic analysis combined with physiological,...

Objective: YABBY is a unique transcription factor family in higher plants, which plays an important role in the development of lateral organs and flowering. In this study, we conducted cloning and bioinformatics analysis of PtYABBY genes, and explored the expression patterns of PtYABBY genes in...

Circular RNAs (circRNAs) are a class of noncoding RNA molecules with ring structures formed by covalent bonds and are commonly present in organisms, playing an important regulatory role in plant growth and development. However, the mechanism of circRNAs in poplar root responses to different forms...

Genus Taphrina includes archaic ascomycetes, included into fission yeasts, with many species parasitizing woody plants, inducing gall-like catkin and fruit curling, blister-like leaf deformation, respectively witch's brooms. American aspens (Populus tremuloides, P. grandidentata), Eurasian aspen (...

Concurrent ground-level ozone (O₃) pollution and anthropogenic nitrogen (N) deposition can markedly influence dynamics and productivity in forests. Most studies evaluating the functional traits responses of rapid-turnover organs to O₃ have specifically examined leaves, despite fine roots are...

Objective: Membrane steroid-binding protein (MSBP) is a type of membrane-associated steroid receptor protein located on the cytoplasmic membrane, and it affects multiple processes of plant growth and development by initiating cell response to hormone regulatory signals, regulating steroid transport ...

To investigate the pivotal physiological processes modulating lead (Pb) tolerance capacities of poplars, the saplings of two contrasting poplar species, Populus × canescens with high Pb sensitivity and Populus nigra with relatively low Pb sensitivity, were treated with either 0 or 8 mM Pb for 6...

Poplars are proposed for the phytoremediation of heavy metal (HM) polluted soil. Characterization of genes involved in HM uptake and accumulation in poplars is crucial for improving the phytoremediation efficiency. Here, Natural Resistance-Associated Macrophage Protein 1 (NRAMP1) encoding a...

Purpose: Roots are the mean absorbing organ of plants and an important part of material circulation in ecosystems. Understanding long-term root system development and its response to soil water availability can help to elucidate carbon cycling and plant resource uptake strategies in forest...
