Summary: This study investigates the regulatory mechanisms of brassinosteroids (BRs) in secondary vascular cambium activity in poplar trees. The results demonstrate that elevated endogenous castasterone levels enhance cambium meristem cell activity and xylem differentiation, promoting secondary stem growth.

Summary: This study explores genetic engineering approaches to enhance cambial activity in poplar plants, specifically through the ectopic expression of a cytokinin biosynthesis gene or a constitutively active cytokinin receptor gene. The findings suggest that these genes can alter the growth characteristics and stem diameter of poplar trees.

Summary: Lignin, a major component of plant cell walls, is crucial for plant growth and development and is regulated by multiple transcription factors. The study demonstrated that the transcription factor PagERF81 negatively regulates lignin biosynthesis, as mutant lines with decreased PagERF81 expression had increased lignin content, while overexpression of PagERF81 reduced lignin. This research provides insights into the regulation of lignin biosynthesis and offers a molecular tool for engineering wood with high lignin content, which has implications for the lignin-related chemical industry and carbon sequestration.

Summary: Increasing salinity negatively affects plant growth by interfering with the supply of other macronutrients like potassium, calcium and magnesium. However, in response to salt stress, leaf potassium levels are positively affected, suggesting enhanced loading and retention compared to transpiration driven cation supply.

Summary: Plant migration and gene flow from genetically modified or exotic trees to nearby lands or by crossing with wild relatives is a major concern. To speed up the assessment of expected floral phenotypes after gene knockout, researchers used a heat-induced FT overexpression method. By studying the effects of CRISPR-Cas9 induced biallelic changes, they obtained flowering in poplar clones and observed a range of inflorescence and floral forms. The findings demonstrate the developmental plasticity of Populus flowers during genetically accelerated flowering and provide insights into the sterility caused by gene knockout.

Summary: The study investigated the effects of mixed cultivation with Robinia on wood growth, wood nitrogen content, and gene expression in poplar. Results indicated that in mixed plots with Robinia, the annual stem increment was reduced, wood nitrogen content was increased, δC-13 in wood decreased, vessel and fiber frequencies increased, and fiber lengths and fiber lumina decreased. Transcriptional profiles showed differences mainly between genotypes and sites, with only one gene and gene ontology term significantly enriched in response to the mixture regardless of poplar genotype and growth location.

Summary: This study focused on the role of the poplar UGT72B37 gene in the glycosylation of monolignols. The findings showed that the absence of UGT72B37 gene led to an increase in lignin content in the xylem of poplar trees, without ectopic lignification in the stems. Additionally, the upregulation of the closely related UGT72B38 gene in the mutant lines suggests a functional compensation between UGT72B37 and UGT72B38 in lignin biosynthesis and accumulation in poplar.

Summary: The results indicate that high temperature accelerates the evolution rate of torrefaction products and promotes the formation of torrefaction volatiles; the heating rate has minimal impact on the torrefaction process evolution; both torrefaction temperature and residence time significantly influence the mass and energy yields of torrefaction products; the majority of the heat from torrefaction reactions is endothermic, with only a small portion being exothermic.

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: The overexpression of TaAMY2 resulted in significant changes in starch visco-properties, increased levels of soluble carbohydrates, and insensitivity to ABA in ripened grains. It was also suggested that alpha-amylase may not be essential for the initial stage of grain germination.

Summary: This study identified miRNAs in the phloem and developing xylem of P. deltoides and investigated their regulatory networks. The findings suggest that these miRNAs play important roles in lignin and cellulose biosynthesis, and a portion of these miRNAs function through the regulation of transcription factor genes.

Summary: Invasive woody perennials pose a threat to ecosystems, and effective herbicides are needed for control. A study investigated the use of the cellulase enzyme 2XL as a herbicide adjuvant and found that it did not improve the effectiveness of glyphosate. However, effective control of the invasive shrub Amur honeysuckle was achieved with lower concentrations of glyphosate.
