Plant exudates-driven microbiome recruitment and assembly facilitates plant health management
Abstract
Plant–microbiome symbiotic interactions play a crucial role in regulating plant health and productivity. To establish symbiotic relationships, the plant secretes a variety of substances to facilitate microbial community recruitment and assembly. In recent years, important progress has been made in studying how plant exudates attract beneficial microorganisms and regulate plant health. However, the mechanisms of plant exudates-mediated microbial community recruitment and assembly and their effects on plant health are no comprehensive review. Here, we summarize the interaction mechanisms among plant exudates, microbial community recruitment and assembly, and plant health. First, we systematically evaluate the type and distribution of plant exudates, as well as their role in microbiome recruitment and assembly. Second, we summarize the mechanisms of plant exudates in terms of microbiome recruitment, diversity regulation and chemotaxis. Finally, we list some typical examples for elucidating the importance of plant exudates in promoting plant health and development. This review contributes to utilizing plant exudate or beneficial microbiome resources to manage plant health and productivity.
This review explores how plant exudates facilitate the recruitment and assembly of beneficial microbial communities, enhancing plant health and productivity through mechanisms like nutrient provision, chemical signaling, and pathogen suppression, while emphasizing their potential in sustainable plant health management strategies.

Woman from Shanghai : tales of survival from a Chinese labor camp
\"Between 1957 and 1960, nearly three thousand Chinese citizens were labeled \"Rightists\" by the Communist Part and banished to Jianiangou in China's northwestern desert region of Gansu to undergo \"reeducation\" through hard labor. These exiles men and women were subjected to horrific conditions, and by 1961 the camp was closed because of the stench of death: of the rougly three thousand inmates, only about five hundred survived.\" \"In 1997, Xianhui Yang traveled to Gansu and spent the next five years interviewing more than one hundred survivors of the camp. In Woman from Shanghai he presents thirteen of their stories, which have been crafted into fiction in order to evade Chinese censorship but which lose none of their fierce power. These are tales of ordinary people facing extraordinary tribulations, time and again securing their humanity against those who were intent on taking it away.\"--Jkt. of 2009 ed.

Ultra-bright and highly efficient inorganic based perovskite light-emitting diodes
Inorganic perovskites such as CsPbX
3
(X=Cl, Br, I) have attracted attention due to their excellent thermal stability and high photoluminescence quantum efficiency. However, the electroluminescence quantum efficiency of their light-emitting diodes was <1%. We posited that this low efficiency was a result of high leakage current caused by poor perovskite morphology, high non-radiative recombination at interfaces and perovskite grain boundaries, and also charge injection imbalance. Here, we incorporated a small amount of methylammonium organic cation into the CsPbBr
3
lattice and by depositing a hydrophilic and insulating polyvinyl pyrrolidine polymer atop the ZnO electron-injection layer to overcome these issues. As a result, we obtained light-emitting diodes exhibiting a high brightness of 91,000 cd m

and a high external quantum efficiency of 10.4% using a mixed-cation perovskite Cs

Advanced geoinformation science
Many of the challenges of the next century will have physical dimensions, such as tsunamis, hurricanes, and climate change as well as human dimensions such as economic crises, epidemics, and emergency responses. With pioneering editors and expert contributors, Advanced Geoinformation Science explores how certain technical aspects of geoinformation have been used and could be used to address such global issues. The editors and chapter authors have been involved in global initiatives such as Global Earth Observation System of Systems (GEOSS) and Digital Earth, and research problems such as air quality, public health, and cloud computing. The book delineates the problems communities are likely to face and how advanced geoinformation science can be a part of their solution. It introduces different methods in collecting spatial data as the initial feeds to geoinformation science and computing platforms. It discusses systems for data management, data integration and analysis, the geoinformation infrastructure, as well as knowledge capture, formatting, and utilization. The book then explores a variety of geoinformation applications, highlighting environmental, agriculture, and urban planning uses.--Publisher's description.

Robust neutralization assay based on SARS-CoV-2 S-protein-bearing vesicular stomatitis virus (VSV) pseudovirus and ACE2-overexpressing BHK21 cells
The global pandemic of coronavirus disease 2019 (COVID-19) is a disaster for human society. A convenient and reliable neutralization assay is very important for the development of vaccines and novel drugs. In this study, a G protein-deficient vesicular stomatitis virus (VSVdG) bearing a truncated spike protein (S with C-terminal 18 amino acid truncation) was compared to that bearing the full-length spike protein of SARS-CoV-2 and showed much higher efficiency. A neutralization assay was established based on VSV-SARS-CoV-2-Sdel18 pseudovirus and hACE2-overexpressing BHK21 cells (BHK21-hACE2 cells). The experimental results can be obtained by automatically counting the number of EGFP-positive cells at 12 h after infection, making the assay convenient and high-throughput. The serum neutralizing titer measured by the VSV-SARS-CoV-2-Sdel18 pseudovirus assay has a good correlation with that measured by the wild type SARS-CoV-2 assay. Seven neutralizing monoclonal antibodies targeting the receptor binding domain (RBD) of the SARS-CoV-2 S protein were obtained. This efficient and reliable pseudovirus assay model could facilitate the development of new drugs and vaccines.

Recurrently deregulated lncRNAs in hepatocellular carcinoma
Hepatocellular carcinoma (HCC) cells often invade the portal venous system and subsequently develop into portal vein tumour thrombosis (PVTT). Long noncoding RNAs (lncRNAs) have been associated with HCC, but a comprehensive analysis of their specific association with HCC metastasis has not been conducted. Here, by analysing 60 clinical samples’ RNA-seq data from 20 HCC patients, we have identified and characterized 8,603 candidate lncRNAs. The expression patterns of 917 recurrently deregulated lncRNAs are correlated with clinical data in a TCGA cohort and published liver cancer data. Matched array data from the 60 samples show that copy number variations (CNVs) and alterations in DNA methylation contribute to the observed recurrent deregulation of 235 lncRNAs. Many recurrently deregulated lncRNAs are enriched in co-expressed clusters of genes related to cell adhesion, immune response and metabolic processes. Candidate lncRNAs related to metastasis, such as
HAND2-AS1
, were further validated using RNAi-based loss-of-function assays. Thus, we provide a valuable resource of functional lncRNAs and biomarkers associated with HCC tumorigenesis and metastasis.

Single cell electron collectors for highly efficient wiring-up electronic abiotic/biotic interfaces
By electronically wiring-up living cells with abiotic conductive surfaces, bioelectrochemical systems (BES) harvest energy and synthesize electric-/solar-chemicals with unmatched thermodynamic efficiency. However, the establishment of an efficient electronic interface between living cells and abiotic surfaces is hindered due to the requirement of extremely close contact and high interfacial area, which is quite challenging for cell and material engineering. Herein, we propose a new concept of a single cell electron collector, which is
in-situ
built with an interconnected intact conductive layer on and cross the individual cell membrane. The single cell electron collector forms intimate contact with the cellular electron transfer machinery and maximizes the interfacial area, achieving record-high interfacial electron transfer efficiency and BES performance. Thus, this single cell electron collector provides a superior tool to wire living cells with abiotic surfaces at the single-cell level and adds new dimensions for abiotic/biotic interface engineering.
Efficient management of electron transfer between living cells and solid abiotic surfaces is quite challenging. Here, the authors report the assembling of single cell electron collector for individual cell to promote the biotic/abiotic interfacial electron transfer at the single-cell level.
