Summary: The developmental characteristics of pollen in the orchid Dendrobium officinale were examined using electron microscopy and light microscopy combined with calcium localization analyses. The study found that before anthesis, the anther wall of D. officinale consists of different layers of cells, and the tapetal cells degenerate while the endothecium cells develop fibrous bands. The microspores in the tetrad of D. officinale do not separate from each other after meiosis, instead, they develop together to form the pollinium.

Summary: The study investigated the pollen developmental characteristics in Dendrobium officinale by examining polysaccharides and lipids. The anther wall of D. officinale consists of multiple layers of different cells. The microspore mother cells undergo simultaneous microsporogenesis without a callose wall. The pollen tetrads inside the pollinium lack the exine structure, and pollen germination mainly occurs from the pollen grains inside the pollinium.

Summary: In this study, an oligosaccharide sequencing analysis was used to successfully correct the backbone of Dendrobium officinale polysaccharide (DOP) to mannan. This analysis involved producing oligosaccharide fragments through mild acid hydrolysis of DOP followed by p-aminobenzoic ethyl ester (ABEE) derivatization. The isolated and identified oligosaccharides with varied polymerization degrees (DP = 2-10) confirmed that the backbone of DOP is a beta-D-1,4-mannan. This oligosaccharide analysis is more straightforward and reliable compared to conventional methods.

Summary: This study characterized a key flavonoid biosynthesis gene, flavanone 3-hydroxylase (F3H), from Dendrobium officinale and found that it was involved in the biosynthesis of flavonoids. The DoF3H protein showed high homology with F3H proteins from other plant species and its mRNA levels were induced by salt and cold stresses. Heterologous expression of DoF3H in Escherichia coli conferred higher tolerance to salt and cold stresses.

Summary: This study explored the protective effect of Dendrobium officinale polysaccharides (DOPs) on reproductive oxidative stress injury in male mice and its mechanism. The results showed that DOPs effectively reduced the oxidative stress injury of testicular tissue and improved sperm quality and hormone levels. The protective effect of DOPs was mediated by reducing oxidative stress levels, improving the hormone environment in testes, and regulating the expression of specific genes in Sertoli cells and spermatogenic cells.

Summary: In this study, the molecular characteristics of fermented Dendrobium officinale polysaccharides (FDOP) by Lactobacillus delbrueckil bulgaricus were analyzed using FT-IR, GPC-LC, and SEM. FDOP showed a smaller molecular structure and better water solubility. The protective effect of FDOP on human skin fibroblasts (HSF) damaged by UV radiation was investigated, and it was found that FDOP improved the antioxidant capacity of HSF and reduced the breakdown of collagen, elastin, and hyaluronic acid. The antioxidative and antiaging properties of FDOP were explored, and it was observed that FDOP could up-regulate the Nrf2/Keapl and TGF-beta/Smads pathways to reduce oxidative damage and aging effects.

Summary: This study indicates that ultrasound treatment can improve the rheological properties of Dendrobium officinale polysaccharide (DOP). Among the samples treated with ultrasound, M-DOP shows the highest capability in scavenging reactive oxygen and nitrogen species radicals in vitro. In a mouse aging model, M-DOP increases antioxidant enzyme activity and reduces pro-inflammatory cytokine levels in the liver. Moreover, M-DOP upregulates the expression of anti-inflammatory/antioxidant proteins through the Nrf2/HO-1/NQO1 signaling pathway.

Summary: This study investigated the response mechanism of Dendrobium officinale, a traditional Chinese herbal medicine, to low nitrogen stress. The results showed that low nitrogen levels significantly inhibited growth, photosynthesis, and superoxide dismutase activity, while peroxidase and catalase activities, polysaccharide and flavonoid content increased. Differential gene expression analysis revealed differences in nitrogen and carbon metabolism, transcriptional regulation, antioxidative stress, secondary metabolite synthesis, and signal transduction under low nitrogen stress. Copious polysaccharide accumulation, efficient assimilation and recycling of nitrogen, and rich antioxidant components played critical roles in D. officinale's response to low nitrogen levels.

Summary: The International Committee of Medical Journal Editors (ICMJE) recommendations are the dominant guidelines for authorship in academic papers. Large language models (LLMs) and AI, such as ChatGPT, challenge the human-based authorship model due to their ability and versatility. Some journals and publishers have prohibited authorship assignment to AI and LLMs, including ChatGPT, as they are not recognized as valid authors.

Summary: ResearchGate (RG) is a popular social media platform for scientists, researchers, or academics (SRAs), which provides the RG Score as a metric to measure an SRA's academic worth, productivity, and interaction. The precise calculation of the RG Score remains undisclosed, making it a proprietary algorithm. RG announced that it will phase out the RG Score in June 2022. This article examines the literature on the RG Score and highlights its potential bias towards certain aspects, such as questions and answers, rather than the published literature of an SRA. The RG Interest Score is also critiqued. An author-based metric that balances important academic factors while disregarding redundant aspects may benefit SRAs. The RG Score should not be used in isolation, manipulated, or used as a basis for financial schemes.

Summary: Citations in scientific papers are important for verifying information and supporting statements. Open citation databases allow researchers to independently verify the validity and accuracy of citations, and can also be used to evaluate research performance. Open citations have the potential to benefit careers, funding, and detect abusive citation strategies. However, challenges such as funding and data security need to be addressed.

Summary: This article discusses the importance of using the Internet Archive to archive journal editorial boards. The authors argue that there are three reasons for doing so: journals may lack formal mechanisms to register changes in the editorial constitution; appreciating changes in the editorial board composition holds historical importance, including changes in gender representation; and changes may be made opaquely to hide information linked to the journal's history. By archiving editorial board pages, a better understanding of the journal's quality assurance can be gained from a historical and bibliometric perspective.

Summary: Tropospheric ozone has significant effects on the remobilization and allocation efficiency of aboveground biomass and nutrients in cereal crops. Long-term ozone exposure increases straw C:N ratio and affects grain C:N ratio. Grain N concentrations increase significantly under ozone stress, but N yield declines due to grain yield losses. Various indicators of N use efficiency are reduced, indicating reduced N absorption from soil and allocation from vegetative to reproductive organs. Straw C:N ratio is not suitable for predicting wheat productivity. Nitrogen harvest index (NHI) is not affected by ozone stress, but the relationship between harvest index (HI) and NHI is changed by elevated ozone concentration.

Summary: This study aimed to investigate the physiological response of broccoli leaves to abiotic stresses such as salinity and boron toxicity/deficiency. The results showed that the combined stress of salinity and boron deficiency resulted in a significant reduction in plant biomass, and the adaptation mechanisms were associated with water and boron concentration in the leaves. The expression patterns of PIP aquaporins varied among the different stress treatments, and their presence in the plasma membrane and interaction with the lipid environment played potential regulatory roles in facilitating salinity-boron stress adaptation mechanisms.

Summary: Plants activate a sophisticated signaling cascade in response to pests and pathogens, with lipids playing a crucial role in mediating these defense responses. Different types of lipids are involved in cell signaling during plant-pathogen interaction and each lipid has specific relevance and contributes to specific signaling cascades. Lipid biosynthetic enzymes, including phospholipases, are involved in the production of defense signaling molecules. Lipids participate in stress signaling by mediating signal transduction, acting as precursors for bioactive molecules, regulating ROS formation, and interacting with phytohormones.
