Abstract Heat shock transcription factor (HSF) are essential regulators of heat shock protein (HSP) gene expression in plants and algae, contributing to their resilience against biotic and abiotic stresses. However, the localization, structure, phylogenetic relationship, and characteristics of PtHSF genes in microalgae, especially in diatom Phaeodactylum tricornutum, remain largely unexplored. This study presents a comprehensive analysis of the PtHSF gene family in P. tricornutum. A genome-wide analysis identified 68 PtHSF genes, which were classified into two distinct subfamilies: traditional and untraditional. Motif and structure analyses revealed evidence of multiple duplication events within the PtHSF gene family. Expression profiling revealed diurnal… More >

Abstract To explore the effect of fertilizers on the yield and quality of Platostoma palustre, in this study, P. palustre was utilized as the research material, and field experiments were conducted with different application rates of compound fertilizer and organic fertilizer and non-targeted metabolomics analysis was further employed to compare and analyze the differences in the metabolic components between the compound fertilizer and organic fertilizer treatments. The results of field experiments demonstrated that both compound and organic fertilizers could promote the fresh weight, shade dry weight, and dry weight of P. palustre, with 450 kg hm⁻² compound fertilizer and 4500… More >

Abstract Clarifying the soil nutrient dynamics caused by forest type variations in the coastal region helps scientifically to apply fertilizer to forest plantations and enhance the carbon (C) sink capacity. Pure forests of Ligustrum and Metasequoia, as well as their mixed forests, in a coastal region of China were investigated by collecting 0–20 and 20–40 cm soil samples and analyzing their differences in bulk density, water content, pH, soil organic matter (SOM), ammonium (NH₄⁺–N), nitrate (NO₃^––N) and total nitrogen (TN), available phosphorus (AP) and potassium (AK), microbial biomass C (MBC) and N (MBN), and enzyme activity. The… More >

Abstract In the present study, an indoor potting experiment was conducted to study the effects of enhanced UV-B radiation and Magnaporthe oryzae on the growth, stomatal structure, photosynthesis, and endogenous hormone contents of a traditional rice cultivar Baijiaolaojing in the Yuanyang terraces of Yunnan Province. In addition, the relationships between these parameters and disease indices were analyzed. We aimed to clarify the response of the photosynthetic physiology of rice under the combined stress of UV-B radiation and M. oryzae. Compared with the M. oryzae infection treatment, all the treatments, including M. oryzae infection before (MBR), simultaneously with (MSR), and after… More >

Abstract Panicle size is one of the important factors in shaping yield potential in rice, but it shows plasticity in different environments, which leads to yield fluctuation. Variations in panicle size among varieties are largely determined by quantitative trait loci (QTLs). QTL analysis could elaborate on the environmental impact on trait plasticity using nearly isogenic lines (NILs) of different QTLs. Two QTLs, ipa1-2D and qPL6 are identified to have pleiotropic contributions to panicle size and plant architecture, but their responses to different growth conditions are still unclear. In this study, we developed NILs harboring a single locus… More >
