Synergistic mechanism between photosynthetic performance and growth of interspecific hybrid scions in Catalpa Scop

Abstract Background and objective Grafting is a pivotal technique for clonal propagation in Catalpa , yet the regulatory mechanism by which scion genetic background coordinates photosynthetic productivity and growth remains elusive. Methods Using two-year-old Catalpa ovata seedli...

Salinity constrains rhizosphere-driven soil carbon mineralization through shifts in microbial communities and enzyme activities

Functional assessment of how the rhizosphere regulates soil carbon (C) mineralization is critical for predicting ecosystem C dynamics under global climate change. However, the mechanisms by which rhizosphere-mediated microbial traits and extracellular enzyme activities influence...

Comparative Transcriptomics Reveals Divergent Expression Patterns Related to Carbon Metabolism, Transport, and Regulation in Juvenile Stems of Four Fagaceae Species

Background/Objectives: We compared juvenile whole-stem transcriptomes of Quercus glauca, Quercus acutissima, Quercus fabri, and Castanopsis sclerophylla to examine carbon metabolism and transport. Methods: Three seedlings per species were sampled in one session. RNA sequencing (R...

Genome-Wide Identification and Expression Pattern Analysis of the DXS Gene Family in Eucommia ulmoides

1-deoxy-D-xylulose-5-phosphate synthase (DXS) is the first key enzyme in the methylerythritol phosphate (MEP) pathway of plant terpenoid biosynthesis, and it plays a vital role in Eucommia ulmoides terpenoid biosynthesis. In this study, bioinformatics methods were used to compreh...

Dual Roles of RAD23b and RAD4 on the Desiccation Tolerance of Germinated Seeds

Desiccation tolerance (DT) is a survival trait enabling orthodox seeds to withstand extremely low water content. While some protective factors are characterised, it remains mechanistically obscure. Here, based on PEG-induced DT re-establishment in germinated Brassica napus L. see...

Conditional cooling from large-scale urban afforestation: ecosystem functioning and planning implications

Large-scale urban afforestation is increasingly promoted as a Nature-Based Solution for reducing urban heat. Yet afforestation does not cool cities uniformly, and the conditions under which it delivers sustained thermal benefits remain poorly understood. This uncertainty limits t...

A Reference-Free K-mer Framework Enhances Genomic Prediction in Highly Heterozygous Woody Species: A Case Study in Litsea cubeba

Abstract Litsea cubeba, an economically important woody species in the Lauraceae, is widely cultivated for spice and essential oil production. Core agronomic traits, particularly fruit morphology and yield per plant, directly determine its commercial value. However, genetic impro...

Rhizosphere-derived Pseudomonas putida EU-36 enhances growth and quality-related metabolite accumulation in Eucommia ulmoides leaves

Sustainable microbial strategies are needed to increase leaf biomass and enhance quality-related metabolite accumulation in Eucommia ulmoides Oliv., a woody medicinal and industrial plant. This study aimed to identify native rhizosphere bacteria, evaluate a selected strain in pot...

Microbial Community Structure Diversity of Male and Female Poplar Plants of the Same Faction and Its Influencing Factors

Phyllosphere microorganisms interact with host plants to regulate growth, promote nutrient uptake and enhance stress tolerance with host specificity, while arbuscular mycorrhizal fungi facilitate plant nutrient absorption and stress adaptation. Current poplar microbial studies mo...

Pollen tube growth: signal perception and temporary growth arrest

Abstract Pollen tubes are among the fastest growing polarized plant cells and must traverse the stigma, style and ovary to deliver male gametes. The style constitutes the longest and most complex phase of this journey yet the molecular and biomechanical logic of pollen tube behav...

Tissue-Resolved Metabolomic Profiling of Ten Prunus salicina × P. armeniaca Cultivars Reveals Peel–Flesh Metabolic Differences Associated with Fruit Color and Antioxidant Capacity

Prunus salicina × P. armeniaca, an interspecific hybrid of Chinese plum and apricot, shows substantial variation in peel and flesh color and quality traits. Ten cultivars were characterized by integrating physicochemical measurements, spectrophotometric assays of phytochemical co...
