Summary: Most existing forest biomass models focus on aboveground biomass, while belowground biomass prediction is insufficient. In this study, extensive destructive sampling was used to measure the root biomass of birch plantation forests. The disaggregated model performed slightly better than the additive model in estimating birch root biomass.

Summary: Phytochrome-interacting factors (PIFs) are transcription factors that regulate plant growth and development. In the Betula platyphylla species, PIF genes (BpPIFs) are involved in light, stress, and hormone responses, and may be regulated by the BpSPL2 gene. This study provides a comprehensive understanding of the BpPIF family and proposes a hypothetical gene network model for adventitious root formation.

Summary: The study highlighted the significant impact of fertilization on tree growth, emphasizing the importance of selecting the right genotypes and fertilization formula for successful forest cultivation. The growth characteristics of 2-year-old seedlings can serve as criteria for selecting superior clones. Through the membership function method, five superior clones were successfully identified, resulting in increased genetic gains in growth traits.

Summary: Tree growth in mountain ecosystems, specifically Betula platyphylla, shows varying growth/climate relationships along an altitudinal gradient in Changbai Mountain of northeast China. The study found that at different altitudes, the growth of BP trees is influenced by different climatic factors, and with continued warming, these trees are expected to move to higher altitudes in the future.

Summary: In this study, 11 BpHMG genes were cloned and characterized from Betula platyphylla, showing response to salt, osmotic stress and ABA treatment. Particularly, BpHMG6 exhibited significant upregulation in birch stems under salt stress. Overexpression of BpHMG6 in birch enhanced salt tolerance by increasing protective enzyme activity and ROS scavenging capacity, while silenced plants showed opposite responses. Therefore, BpHMG6 potentially plays a role in salt stress tolerance in transgenic birch plants.

Summary: This study identified 68 WRKY transcription factors in white birch and classified them into four main groups. The physiochemical properties of these factors were analyzed, and most were found to be located in the nucleus. Synteny analysis revealed relationships between white birch WRKYs and those from other plant species. Additionally, the study found that the promoters of BpWRKYs were enriched with cis-acting elements related to various plant biological processes. Expression analysis and interaction assays further supported the importance of BpWRKYs in stress response.

Summary: This study identified 26 BpDof genes in birch through whole-genome analysis, revealing diversity in structure, expression, and function in response to drought stress. Overexpressing BpDof4, BpDof11, and BpDof17 genes enhanced plant tolerance to drought, showing improved ROS scavenging capabilities and reduced cell damage in birch.

Summary: The study reveals the important role of the TGA7 gene in floral transition in Arabidopsis thaliana, regulated by both autonomous and thermosensory pathways. Through differential gene expression analysis, it was found that FLC and MAF5 genes may be primarily responsible for the delayed-flowering phenotype in tga7.

Summary: This study investigated the metabolic responses associated with tension-wood formation in Betula platyphylla Suk (Asian white birch). The xylem growth rate and cellulose content of tension wood (TW) were higher than that of opposite wood (OW). Metabolomics analysis identified 183 metabolites, of which 142 showed altered levels in TW compared to normal wood (NW). Metabolites related to fatty-acid and amino-acid metabolism, glycolytic pathway, and the metabolism of fructose, mannose, and starch-sucrose were abundant in TW.

Summary: In this study, researchers cloned and characterized a C2H2-type zinc finger protein gene from Betula platyphylla and found that it plays a crucial role in salt stress response. Overexpression of this gene in birch enhanced salt tolerance. Further experiments showed that the gene is involved in multiple signaling pathways, such as ABA synthesis and proline synthesis, to enhance the defense against salt stress in birch.
