Long non-coding RNAs (lncRNAs) play crucial roles in plant growth, development, and stress responses. With the advancement of single-cell RNA sequencing (scRNA-seq) technology, it is now possible to investigate lncRNA expression and function at single-cell resolution. Although several plant single-cell transcriptome databases have been established, they predominantly focus on protein-coding genes while largely overlooking lncRNAs.

Plasticity of floral longevity (FL) in response to pollination enables plants to maximize opportunities for pollen receipt and export under unfavorable pollination conditions, while minimizing costs under favorable ones, playing a crucial role in plant pollination. However, the prevalence of floral longevity plasticity (FLP) across the angiosperms remains unclear. Using data for FL consisting of 397 comparisons from 188 species, we provide the first global, cross-species quantification of FLP and assess its association with a range of biotic and abiotic factors.

Delayed luminescence (DL) is a quantized signal that is characteristic of photoexcited molecules entering a relaxed state. Studying DL provides critical insight into photophysical mechanisms through the analysis of specific spatiotemporal dynamics. In this study, we developed a high-sensitivity DL imaging system using a quantitative scientific complementary metal-oxide-semiconductor (qCMOS) camera and a single-photon counting resolution.

Pu-erh tea polyphenol aggregates (PTPAs), macromolecular complexes analogous to theabrownin formed during microbial fermentation, are key bioactive components in this tea. Although their bioactivities are documented, critical gaps persist regarding both precise structural features and molecular mechanisms underlying the anti-inflammatory efficacy across biological models. To address these limitations, we systematically analyzed PTPAs using integrated methods, including alkaline hydrolysis, acid hydrolysis, and benzyl mercaptan-mediated degradation.

() is a globally distributed fungal genus, traditionally recognized as a group of plant pathogens, with most members known to cause severe plant diseases. However, recent studies have demonstrated that many of these fungi can also colonize plants endophytically, with certain strains capable of promoting plant growth and stimulating the production of secondary metabolites. In this study, 13 strains of were isolated from the stems and leaves of and in Yunnan Province, China.

The structural and ecological significance of ericoid mycorrhizal (ErM) fungi is well recognized. Yet, it remains unknown whether the coexistence of ericaceous plants is facilitated by their symbioses with ErM fungi. Here, we use Rhododendron (Ericaceae) as a model to investigate how phylogenetic and functional limiting similarity, or facilitation through ErM fungal metacommunity, influences their co-occurrence in mountain ecosystems.

Premature ovarian insufficiency (POI) and age-related natural-aging ovarian insufficiency (ARNA-OI) pose pressing global health challenges, necessitating effective therapeutic strategies and a deep understanding of their underlying mechanisms. This study investigates how HEP14, a PKC pathway activator, boosts the regenerative potential of human adipose-derived stem cells (hADSCs) for ovarian regeneration. Transcriptome analysis reveals that HEP14 modulates gene expression profile in hADSCs, enhancing their regenerative capacity.

Terpene cyclases catalyze exquisite and complicated cyclization reactions to generate diverse terpenoid skeletons. Trichoderma fungi are important biocontrol agents, characteristic of producing complex bioactive tetracyclic diterpenoids named harzianes and trichodermanins, but their biosynthesis and biological functions have long been enigmatic. Here we identify TriDTCs, an unprecedented family of terpene cyclases in Trichoderma, responsible for cyclizing geranylgeranyl diphosphate (GGPP) into major diterpenes harzianol I and wickerol A, via heterologous expressions, gene deletion, and in vitro assays.
