Ordered rise and disordered fall: dynamic changes of membrane lipids during girdling-induced tree mortality in Populus yunnanensis.

Understanding the mechanisms behind drought-induced tree mortality is crucial for predicting the impact of global climate change on forests. We studied the mechanism at the cellular level in Populus yunnanensis by profiling membrane lipid molecules in leaves, branch phloem, top and bottom trunk phloem under trunk-girdling-induced drought conditions. We found that both lipid composition and content changed, depending on the tree's tissue positions and the progression of the girdling effect.

Constructing a Conformer-Explorer Identity in Pandemic Narratives: A Qualitative Study of Chinese Emerging Adults.

Existing research indicates that social crises such as the COVID-19 pandemic reshaped young people's sense of self, but little is known about what identities emerging adults construct in their pandemic narratives. Following propositions of narrative identity and Terror Management Theory, this qualitative study investigated Chinese emerging adults' identity construction in their narratives of the national outbreak of the COVID-19 pandemic in late 2022. Participants were 62 college students invited to share their pandemic experiences with reflections.

Hypoglycemic Effect of Rambutan (Nephelium lappaceum L.) Peel Polyphenols on Type 2 Diabetes Mice by Modulating Gut Microbiota and Metabolites.

Scope: Type 2 diabetes mellitus (T2DM) is a metabolic disease with a major global public health effect. Rambutan peel polyphenols (RPPs) have been reported to exert hypoglycemic activity. However, few studies have been explored from the viewpoint of gut microbiota and its metabolites.

Cadmium and calcium ions' effects on the growth of Pleurotus ostreatus mycelia are related to phosphatidylethanolamine content.

Heavy metal Cd can easily be accumulated by fungi, causing significant stress, with the fungal cell membrane being one of the primary targets. However, the understanding of the mechanisms behind this stress remains limited. This study investigated the changes in membrane lipid molecules of Pleurotus ostreatus mycelia under Cd stress and the antagonistic effect of Ca on this stress.

Widely targeted volatilomics and transcriptome analyses reveal the differences in volatile organic components in differently shaped Amomum tsao-ko fruits.

Background: Amomum tsao-ko is an important aromatic crop used in medicines and food. It can be categorized into three main types based on the fruit shape: long (L), oval (O), and round (R). However, limited information is available on the volatile substances present in differently shaped A.

m5C and m6A modifications regulate the mobility of pumpkin CHOLINE KINASE 1 mRNA under chilling stress.

Mobile mRNAs serve as crucial long-distance signaling molecules, responding to environmental stimuli in plants. Although many mobile transcripts have been identified, only a limited subset has been characterized as functional long-distance signals within specific plant species, raising an intriguing question about whether the prevalence of species specificity in mobile transcripts implies a divergence in the mechanisms governing mRNA mobility across distinct plant species. Our study delved into the notable case of CHOLINE KINASE 1 (CK1), an extensively studied instance of mobile mRNAs regulated by a tRNA-like sequence (TLS) in Arabidopsis (Arabidopsis thaliana).

Strain-Driven Phase Transitions in Delafossite CuAAlO: A Key to Enhanced Photo(electro)catalytic Performance.

This study investigates the impact of intrinsic strain and phase transitions on the thermodynamic stability and electronic properties of CuAAlO solid solutions, which are key to their photocatalytic performance. It is demonstrated that CuAAlO with A = Ag, Au, Pt can form continuous isostructural solid solutions due to relatively small compressive strain, while a substantial increase strain restricts CuPdAlO to forming only limited solutions. For A = Li, Na, the formation of heterostructural solid solutions is facilitated by structural motif alterations, accommodating significant differences in ionic radii and A-O bond characteristics.

Accurate prediction of spatial distribution of soil potentially toxic elements using machine learning and associated key influencing factors identification: A case study in mining and smelting area in southwestern China.

Accurate prediction of spatial distribution of potentially toxic elements (PTEs) is crucial for soil pollution prevention and risk control. Achieving accurate prediction of spatial distribution of soil PTEs at a large scale using conventional methods presents significant challenges. In this study, machine learning (ML) models, specially artificial neural network (ANN), random forest (RF), and extreme gradient boosting (XGB), were used to predict spatial distribution of soil PTEs and identify associated key factors in mining and smelting area located in Yunnan Province, China, under the three scenarios: (1) natural + socioeconomic + spatial datasets (NS), (2) NS + irrigation pollution index (IPI) datasets, (3) NS + IPI + deposition (DEPO) datasets.

Comprehensive analysis of pepper (Capsicum annuum) RAV genes family and functional identification of CaRAV1 under chilling stress.

Background: Despite its known significance in plant abiotic stress responses, the role of the RAV gene family in the response of Capsicum annuum to chilling stress remains largely unexplored.

Results: In this study, we identified and characterized six members of the CaRAV gene subfamily in pepper plants through genome-wide analysis. Subsequently, the CaRAV subfamily was classified into four branches based on homology with Arabidopsis thaliana, each exhibiting relatively conserved domains within the branch.

gen. nov., sp. nov. and sp. nov., isolated from desert soil.

Two Gram-stain-negative, aerobic, milk-white coloured, non-motile, short rod-shaped bacteria, designated as strains SYSU D60010 and SYSU D60012, were isolated from sand samples collected from the Taklimakan Desert of Xinjiang Province in China.
