A frameshift mutation in resolves the growth versus defense dilemma in rice.

CRISPR-Cas9 genome editing systems have revolutionized plant gene functional studies by enabling the targeted introduction of insertion-deletions (INDELs) via the nonhomologous end-joining (NHEJ) pathway. Frameshift-inducing INDELs can introduce a premature termination codon and, in other instances, can lead to the appearance of new proteins. Here, we found that mutations in the rice jasmonate (JA) signaling gene by CRISPR-Cas9-based genome editing did not affect canonical JA signaling.

Root-secreted (-)-loliolide mediates chemical defense in rice and wheat against pests.

Background: Plant chemical defense can be elicited by signaling chemicals. As yet, the elicitation is mainly known from volatile aboveground signals. Root-secreted belowground signals and their underlying mechanisms are largely unknown.

Discrimination of relatedness drives rice flowering and reproduction in cultivar mixtures.

The improvement of performance and yield in both cultivar and species mixtures has been well established. Despite the clear benefits of crop mixtures to agriculture, identifying the critical mechanisms behind performance increases are largely lacking. We experimentally demonstrated that the benefits of rice cultivar mixtures were linked to relatedness-mediated intraspecific neighbour recognition and discrimination under both field and controlled conditions.

Fe-TiO/TiO S-scheme homojunction for efficient photocatalytic CO reduction.

CO-to-high value-added chemicals via a photocatalytic route is of interest but strangled by the low efficiency. Herein, a novel Fe-TiO/TiO S-scheme homojunction was designed and constructed by using a facile surface modification approach whereby oxygen vacancy (OV) and Fe introducing on the TiO nanorod surface. The as-synthesized Fe-TiO/TiO S-scheme homojunction exhibits positive properties on promoting photocatalytic CO reduction: i) the nanorod structure provides numerous active sites and a radical charge transfer path; ii) the doped Fe and OV not only synergistically enhance light utilization but also promote CO adsorption; iii) the Fe-TiO/TiO S-scheme homojunction benefits photoexcited charge separation and retains stronger redox capacity.

Fluorescent Carbon Dioxide-Based Polycarbonates Probe for Rapid Detection of Aniline in the Environment and Its Biomarkers in Urine.

Aniline compounds, as a class of widely used but highly toxic chemical raw materials, are increasingly being released and accumulated in the environment, posing serious threats to environmental safety and human health. Therefore, developing detection methods for aniline compounds is of particular significance. Herein, we synthesized the fluorescent third monomer cyano-stilbene epoxide M and ternary copolymerized it with carbon dioxide (CO) and propylene oxide (PO) to synthesize carbon dioxide-based polycarbonate (PPCM) with fluorescence recognition functions, as well as excellent performance, for the first time.

Research Progress of Caspase in Endometriosis.

Endometriosis, a common chronic gynecological disease, refers to the presence and proliferation of endometrial tissue in locations other than the uterine cavity. Approximately 6 to 10% of the population of women of childbearing age are known to have endometriosis; the most common clinical signs are pelvic pain and infertility. Although endometriosis is a benign disease, it exhibits some typical features of malignant tumors, such as proliferation, invasion, metastasis, and recurrence.

Analysis of AlN monolayer as a prospective cathode for aluminum-ion batteries.

Developing cathode materials with high specific capability and excellent electrochemical performance is crucial for the advancement of aluminum-ion batteries, which leverage the high theoretical energy density of aluminum metal anodes. In this paper, we investigated the interaction ofAlCl4cluster and Al atom with AlN (-100) and (001) monolayer using density functional theory to assess the applicability of AlN as cathode material for aluminum-ion batteries. The results show that the AlN (001) monolayer is the most effective for adsorbing and accommodatingAlCl4clusters.

(-)-Loliolide is a general signal of plant stress that activates jasmonate-related responses.

The production of defensive metabolites in plants can be induced by signaling chemicals released by neighboring plants. Induction is mainly known from volatile aboveground signals, with belowground signals and their underlying mechanisms largely unknown. We demonstrate that (-)-loliolide triggers defensive metabolite responses to competitors, herbivores, and pathogens in seven plant species.

Root placement patterns in allelopathic plant-plant interactions.

Plants actively respond to their neighbors by altering root placement patterns. Neighbor-modulated root responses involve root detection and interactions mediated by root-secreted functional metabolites. However, chemically mediated root placement patterns and their underlying mechanisms remain elusive.

Potential Mechanisms and Effects of Chinese Medicines in Treatment of Diabetic Atherosclerosis by Modulating NLRP3 Inflammasome: A Narrative Review.

Nucleotide-binding oligomerization domain-like receptor family pyrin domain-containing 3 (NLRP3) is an intracellular sensor that detects endogenous danger signals and environmental irritants to assemble into the NLRP3 inflammasome. Activation of the NLRP3 inflammasome leads to the secretion of the proinflammatory cytokines interleutkin (IL)-1β and IL-18 and induces pyroptosis. Recent studies have shown that the NLRP3 inflammasome participates in the initiation and progression of diabetic atherosclerosis through pathological mechanisms such as β-cell dysfunction, insulin resistance, endothelial cell dysfunction, monocyte adhesion and infiltration, and smooth muscle cell proliferation and migration.

Associations of sex hormone levels with body mass index (BMI) in men: a cross-sectional study using quantile regression analysis.

Body mass index (BMI) has been increasing globally in recent decades. Previous studies reported that BMI was associated with sex hormone levels, but the results were generated via linear regression or logistic regression, which would lose part of information. Quantile regression analysis can maximize the use of variable information.
