Abstract Global warming is making plants more susceptible to heat stress. Hence, adjustments to crop production systems are required for global food security. Heat stress (HS) poses a threat to the quality of ecosystems and global food security due to its adverse effects on plant development. The degree to which HS affects physiological disruptions, physical harm, and biochemical changes at various growth stages directly correlates with its effects on physiological functions, plant growth, and crop production. One promising approach is soil modification using biochar, which enhances soil health and promotes the development of microbial communities, ultimately… More >

Abstract Taxus cuspidata, a rare species of the Taxus genus, and its wild resources are under severe threat. The development of cultivated species has become an important strategy to replace wild species. The objective of this work was to elucidate the differences in secondary metabolite accumulation, particularly in the paclitaxel biosynthesis pathway, between wild and cultivated species. This study employed liquid chromatography-tandem mass spectrometry (LC-MS/MS) and RNA sequencing (RNA-Seq) technologies to conduct integrated metabolomic and transcriptomic analyses of wild and cultivated species of T. cuspidata. The results showed that the content of paclitaxel in cultivated species was significantly higher… More >

Abstract To systematically examine the tolerance of flue-cured tobacco K326 to soil drought stress, this study set up different water content trials for K326 at 60%, 40%, and 20% levels during the vigorous growing period by greenhouse pot planting. Pigment content, chlorophyll fluorescence parameters, antioxidant enzyme activity, and SPS and GS activities associated with carbon and nitrogen metabolism were investigated in the K326 tobacco leaves. The results showed that chlorophyll a and chlorophyll b contents decreased, non-photochemical quenching coefficient Y(NPQ) decreased in the later stage of vigorous growth, and energy dissipation quantum yield Y(NO) levels increased… More >

Abstract Heavy metal (HM) accumulation in soil poses a major hazard to both ecological health and plant growth progressions. Cadmium (Cd), lead (Pb), copper (Cu), chromium (Cr), arsenic (As), zinc (Zn), and nickel (Ni) are examples of HMs that negatively impact the growth and development of plants, resulting in lower agricultural output and food safety concerns. Biochar (BC), a substance rich in carbon that is formed by pyrolyzing natural biomass, has demonstrated remarkable promise in reducing HM stress in polluted soils. Research has shown that BC effectively lowers plant uptake of metals, and enhances soil qualities,… More >

Abstract bHLH transcription factors, widely exist in various plants, and are vital for the growth and development of these plants. Among them, many have been implicated in anthocyanin biosynthesis across various plants. In the present study, a PdbHLH57 gene, belonging to the bHLH IIIf group, was characterized, which was isolated and cloned from the colored-leaf poplar ‘Zhongshancaiyun’ (ZSCY). The cDNA sequence of PdbHLH57 was 1887 base pairs, and the protein encoded by PdbHLH57 had 628 amino acids, the isoelectric point and molecular weight of which were 6.26 and 69.75 kDa, respectively. Through bioinformatics analysis, PdbHLH57 has been classified… More >

Abstract In recent years, the world has faced rising global temperatures, accumulative pollution, and energy crises, stimulating scientists worldwide to strive for eco-friendly and cost-effective solutions. Biochar has materialized as a
favorable tool for environmental remediation, indicating efficacy as an efficient sorbent substance for both
inorganic and organic pollutants in environmental field. These unique properties exclude improved surface
functionality, porous morphology, large specific surface area (SSA), cation exchange capacity (CEC), robust
adsorption capabilities, environmental stability, and embedded micronutrients. Biochar exhibited potential
characteristics for environmental oversight, greenhouse gas (GHG) emission reduction, and soil fertility improvement. This review… More >
