    Abstract This study was aimed to investigate the craniocerebral magnetic resonance imaging (MRI) measurement and clinical characteristics of patients with neuromyelitis optica (NMO) and multiple sclerosis (MS). 50 patients with NMO (NMO group) and 50 patients with MS (MS group) were studied. The clinical manifestations, brain injury morphology, MRI signal characteristics, brain distribution characteristics, and related laboratory tests (serum aquaporin 4 [AQP4] antibody) were statistically analyzed. The results showed that the analysis of clinical manifestations of patients revealed that optic neuritis (37 cases) was the most common disease in NMO patients, and myelitis (16 cases) was more common in MS patients than NMO patients. There were significant differences in gender ratio, abnormal expression of brain MR1, positive serum AQP4-IgG, and other immune diseases and symptoms between the two groups (

    Abstract The mu oil tree (Vernicia montana Lour.) is a dioecious species, but the genetic mechanisms underlying its phenotypic sexual dimorphism are unclear. In this study, we determined two pivotal phases of sex differentiation of mu oil tree via morphological and histological analyses of unisexual flowers: (I) differentiation of male or female primordia to produce staminate flowers (SFs) or transient hermaphrodite flowers (HFs), and (II) complete abortion of stamens in transient HFs to generate pistillate flowers (PFs). A total of 1621 sex-biased genes were identified by comparative transcriptome analysis which exhibited elevated rates of protein evolution than unbiased genes. The female-biased genes were enriched in the production of defense compounds while male-biased genes were focused on the production of viable pollens. Transcriptome-based analysis revealed that the differentially expressed genes (DEGs) between PFs and SFs in phase I involved in abscisic acid (ABA), auxin (AUX), cytokinin (CK), ethylene (ET), and gibberellin (GA) biosynthesis and signaling showed higher expression levels in males than in females in general, whereas the DEGs involved in jasmonic acid (JA) and salicylic acid (SA) pathways displayed opposite expression patterns. Moreover, differentially expressed endogenous ABA, AUX, GAs, JA, and SA exhibited consistent biased expression patterns with the DEGs by UPLC-MS-based analysis. Exogenous application of an anti-ethylene plant growth regulator could promote the development of stamens in PFs and generated HFs. Comparative transcriptomic and hormonal analyses of PFs and SFs in phase II indicated an increase in ET concentration when abortion of stamens in PFs occurred. This study suggested that phytohormones play key roles in sex dimorphism and ET may determine the development of stamens in PFs of mu oil tree, which provides an insight into plant sex differentiation mechanisms.

    Abstract Ethnopharmacological relevance: Nocardiosis is an uncommon infectious disease that bears certain similarities to tuberculosis, with a continuous increase in its incidence and a poor prognosis. In traditional Chinese medicine, the leaves of Cajanus cajan (L.) Millsp. are employed to treat wounds, malaria, coughs, and abdominal pain.
    Aim of the study: In this study, we investigated the effects and mechanisms of longistylin A (LGA), a natural stilbene isolated from C. cajan, as a potential antibiotic against nocardiosis.
    Materials and methods: LGA was isolated from the leaves of C. cajan and assessed using a minimum bactericidal concentration (MBC) determination against Nocardia seriolae. Multi-omics analysis encompassing genes, proteins, and metabolites was conducted to investigate the impact of LGA treatment on N. seriolae. Additionally, quantitative analysis of 40 cytokinins in N. seriolae mycelium was performed to assess the specific effects of LGA treatment on cytokinin levels. Cryo-scanning electron microscopy was utilized to examine morphological changes induced by LGA treatment, particularly in the presence of exogenous trans-zeatin-O-glucoside (tZOG). The therapeutic effect of LGA was investigated by feeding N. seriolae-infected largemouth bass.
    Results: LGA exhibited significant efficacy against N. seriolae, with MBC value of 2.56 μg/mL. Multi-omics analysis revealed that LGA disrupted glycerophospholipid metabolism and hormone biosynthesis by notably reducing the expression of glycerol-3-phosphate dehydrogenase and calmodulin-like protein. Treatment with LGA markedly disrupted 12 distinct cytokinins in N. seriolae mycelium. Additionally, the addition of exogenous tZOG counteracted the inhibitory effects of LGA on filamentous growth, resulting in mycelial elongation and branching. Furthermore, LGA treatment improved the survival rate of largemouth bass infected with N. seriolae.
    Conclusions: We found for the first time that LGA from C. cajan exhibited significant efficacy against N. seriolae by interfering with glycerophospholipid metabolism and cytokinin biosynthesis.

    Abstract Leucine-rich repeat-containing genes (LRRs) have been reported to play important roles in responses to diseases. However, we poorly understood the response of LRRs to Fusarium wilt infection in tung tree (Vernicia fordii), which is an important economic tree. Here, 437 LRR-containing proteins containing nine types of LRR domains were identified in V. fordii genome. Phylogenetic analysis suggested that nine types of LRR domains could not be divided into separate classes, implying that these LRR domains had a common origin. Totally, 27 LRRs were related to possible resistance to Fusarium wilt after 2, 8, and 13 days post-inoculation. We further found that Vf06G1605 was up-regulate under Fusarium wilt infection after these three time points, Vf10G1602 and Vf02G1413 were up-regulated at 8, and 13 dpi, while Vf07G2320 was down-regulated at these three time points. The WGCNA and promoter elements suggested that WRKY possibly regulate the responses of LRRs to Fusarium wilt infection. This study highlighted the phylogeny and function of LRRs in V. fordii and provided a systematic analysis of these genes in the V. fordii genome. Our results presented here might clearly illustrate physiological mechanisms of resistance to Fusarium wilt infection and the target of marker-assisted breeding in V. fordii.

    Abstract Leucine-rich repeat receptor-like protein kinases (LRR-RLKs) are vital for plant growth and development, signal transduction, immunity, and play diverse roles in plant defense responses. However, the LRR-RLK genes have not been systematically studied in Vernicia fordii (tung tree), especially its response to Fusarium wilt. Here, we carried out an integrative analysis of LRR-RLKs among five Euphorbiaceae species: Hevea brasiliensis (rubber tree), Manihot esculenta (cassava), Jatropha curcas (physic nut), Ricinus communis (castor bean), and V. fordii, which contained 223, 311, 186, 138, and 167 LRR-RLKs, respectively. Maximum-likelihood tree was estimated using LRR-RLKs of Arabidopsis thaliana as a template, and they allowed us to divide Euphorbiaceae LRR-RLKs into 22 groups. There are 126 segmental and 30 tandem duplications in these Euphorbiaceae genomes by synteny analysis. The tissue-specific expression patterns revealed that V. fordii LRR-RLKs (VfLRR-RLKs) were differentially expressed in various tissues, and some of them exhibited specific expression in meristems tissues, which suggested their potential functions during organ formation and cell fate specification. Two VfLRR-RLK pairs (Vf01G2125 and Vf03G1740, Vf06G2687 and Vf10G1659), which generated by tandem duplication events, were associated with possible resistance to Fusarium wilt infection. The qRT-PCR confirmed these four VfLRR-RLKs contained opposite expression profiles during pathogen infection in V. fordii and V. montana. Taken together, our data systematically analyzed the LRR-RLK family in Euphorbiaceae genomes for the first time. We highlight the putative roles of VfLRR-RLKs in response to Fusarium wilt infection, and VfLRR-RLKs may be further applied in marker-assisted breeding to control Fusarium wilt in V. fordii.

    Abstract Aluminum (Al) solubilizes into trivalent ions (Al³⁺) on acidic soils, inhibiting root growth. Since about 13% of global rice cultivation is grown on acidic soils, improving Al tolerance in rice may significantly increase yields. In the present study, metabolome analysis under Al toxicity between the Al-tolerant variety Nipponbare and the Al-sensitive variety H570 were performed. There were 45 and 83 differential metabolites which were specifically detected in Nipponbare and H570 under Al toxicity, respectively. Furthermore, the results showed that 16 lipids out of 45 total metabolites were down-regulated, and 7 phenolic acids as well as 4 alkaloids of 45 metabolites were up-regulated in Nipponbare, while 12 amino acids and their derivatives were specifically detected in H570, of which 11 amino acids increased, including L-homoserine and L-methionine, which are involved in cysteine synthesis, L-ornithine and L-proline, which are associated with putrescine synthesis, and 1-aminocyclopropane-1-carboxylate, which is associated with ethylene synthesis. The contents of cysteine and s-(methyl) glutathione, which were reported to be related to Al detoxification in rice, decreased significantly. Meanwhile, putrescine was accumulated in H570, while there was no significant change in Nipponbare, so we speculated that it might be an intermediate product of Al detoxification in rice. The differential metabolites detected between Al-tolerant and -sensitive rice variants in the present study might play important roles in Al tolerance. These results provide new insights in the mechanisms of Al tolerance in rice.

    Abstract This study examined the associations of overall and domain-specific (i.e., occupational, transport, and leisure-time) sedentary behaviors with cardiovascular disease (CVD) risk factors among high-tech company employees in Taiwan. A total of 363 participants employed at high-tech companies (mean age ± standard deviation: 37.4 ± 7.2 years) completed a questionnaire administered by email regarding their overall, occupational, transport, and leisure-time sedentary behaviors. Self-reported data of height and weight, blood pressure, blood sugar, and total cholesterol levels were also collected in 2018. An adjusted binary logistic regression model was employed in the analysis. After adjusting for sociodemographic variables, high-tech company employees who used a computer (or Internet) for more than 2 h per day during their leisure time were more likely to have CVD risk factors (odds ratio: 1.80; 95% confidence interval: 1.08-3.00). No significant associations with CVD risk factors were detected for total sedentary time, occupational sitting, television viewing time, and transport-related sitting. Despite the nature of cross-sectional design in this study, our findings may have considerable implications for intervention designers and policymakers of Taiwan. Developing effective strategies for limiting leisure-time computer use should be considered for the prevention of CVD among high-tech company employees.
