Summary: This study constructed the lncRNA/circRNA-miRNA-mRNA regulatory network of cambium activity periodicity in Populus tomentosa and found that these non-coding RNAs play important roles in this process. Morphological observation and transcriptome profiling revealed changes in cell wall properties and differential expression of non-coding RNAs. GO enrichment and KEGG pathway analysis further revealed the functions and metabolic pathways of the target genes regulated by these non-coding RNAs. These findings provide new insights into the regulation of activity-dormancy transition.

Summary: This study evaluated the genetic inheritance of growth traits, identified suitable deployment zones, and determined optimal triploid hybrids for different experimental sites. Significant clonal and site effects as well as clone-site interactions were observed for all growth and yield traits. The Weixian, Gaotang, and Yanzhou sites were suitable deployment zones, while Zhengzhou, Taiyuan, Pinggu, and Xiangfen sites were optimal for deployment. Yield performance and stability varied significantly among all triploid hybrids, highlighting the need for a suitable clone that performs well across all sites. The triploid hybrid clone S2 was identified as the ideal genotype based on both performance and stability.

Summary: The development of secondary vascular tissue enhances the transport capacity and mechanical strength of plant bodies, contributing significantly to the world's biomass in the form of wood. The cambium, as the vascular meristem, is a unique stem cell population arising post-germination and exhibiting bifacial differentiation of xylem and phloem. Recent research in Arabidopsis thaliana has shed light on the molecular mechanisms regulating cambium initiation, patterning, and maintenance.

Summary: In this study, the researchers investigated the role of PagSAG101a in secondary xylem development. They found that PagSAG101a is primarily expressed in lignified stems and plays a crucial role in regulating plant growth and wood development by controlling cambium cell division activity and secondary cell wall deposition.

Summary: Drought stress caused by global warming has led to tree mortality and the evolution of water conservation strategies. Overexpression of PtoMYB142 in Populus tomentosa resulted in a dwarfism phenotype and improved drought resistance. PtoMYB142 modulates gibberellin catabolism by binding to the promoter of PtoGA2ox4, a gene induced under drought stress.

Summary: The need for alternative and environment-friendly fuels has led to the exploration of methanol as a renewable fuel. Methanol can be synthesized from waste biomass using different routes, such as through the involvement of methanotrophs or the enzyme PME. This review discusses the methodologies for utilizing biogas from waste biomass as a feedstock for methanol production and identifies areas for future research to overcome limitations.

Summary: Shoot apical and lateral meristems are important for both primary and secondary growth in plants. In this study, the roles of long non-coding RNAs (lncRNAs) in the regulation of primary and secondary growth in Populus were investigated. A total of 1298 lncRNAs were identified in the shoot apical meristem and vascular cambium, and their differential expression patterns were analyzed. The results showed that these differentially expressed lncRNAs mainly influenced the expression of genes related to the ribosome pathway, plant hormone signal pathway, and photosynthesis pathway. Furthermore, the study identified six key lncRNAs and their target genes involved in plant secondary metabolites, cellulose and lignin synthesis, and hormone and signal transduction. The findings provide new insights into the lncRNA-mRNA networks in the development of vascular cambium in Populus.

Summary: In this article, the authors review the concept of "cambial variants" and propose the term "vascular variants" as a more inclusive framework. They classify alternative vascular ontogenies into three categories based on their developmental origin: procambial variants, cambial variants, and ectopic cambia. The authors provide an overview of the developmental diversity and phylogenetic distribution of vascular variants in selected seed plants and discuss the evolutionary implications.

Summary: In this study, the researchers identified a key gene, PtoDPb1, that plays a crucial role in wood formation. Overexpression of PtoDPb1 led to significant changes in cellulose content, fiber length, and fiber width in transgenic poplar. By further analysis, a complete gene module, PtoWAK106-PtoDPb1-PtoE2Fa-PtoUGT74E2, responsible for regulating fiber properties in Populus, was discovered. Additionally, two PtoDPb1 haplotypes were found to affect protein interaction efficiency with other genes.
