Comprehensive analysis of R2R3-MYB transcription factors reveals OsMYB1 as a key regulator of anthocyanin biosynthesis in rice.

R2R3-MYB transcription factors (TFs) are key regulators of plant development, stress responses, and secondary metabolism, with a central role in anthocyanin biosynthesis. However, a comprehensive understanding of the R2R3-MYB TFs involved in anthocyanin accumulation in rice (Oryza sativa L.) remains limited.

Transcriptomic and metabolomic analyses of Tartary buckwheat roots during cadmium stress.

Cadmium (Cd) can adversely damage plant growth. Therefore, understanding the control molecular mechanisms of Cd accumulation will benefit the development of strategies to reduce Cd accumulation in plants. This study performed transcriptomic and metabolomic analyses on the roots of a Cd-tolerant Tartary buckwheat cultivar following 0 h (CK), 6 h (T1), and 48 h (T2) of Cd treatment.

Formulation, Characterization, Antibacterial Activity, Antioxidant Activity, and Safety Evaluation of Essential Oil Nanoemulsions Through High-Pressure Homogenization.

The volatility, instability, and water insolubility of essential oil (CLEO) limit its practical applications in the food, pharmaceutical, and cosmetics industries. CLEO nanoemulsions (CLNEs) were formulated and characterized to overcome the aforementioned issues. The volatile compounds of CLEO were identified by gas chromatography-mass spectrometry.

Genome-wide analysis of the potato GRF gene family and their expression profiles in response to hormone and Ralstonia solanacearum infection.

Background: Potato (Solanum tuberosum L.) is one of the most economically significant crops globally. Nevertheless, potato cultivation is becoming increasingly susceptible to a multitude of diseases, including bacterial wilt, which is caused by Ralstonia solanacearum.

Metformin administration during pregnancy tends to reduce the risk of gestational diabetes mellitus and improve pregnancy outcomes in previously infertile women with polycystic ovary syndrome who become pregnant.

Objective: Metformin reduces incidences of miscarriage and preterm delivery in polycystic ovary syndrome (PCOS) women, but its impact on gestational diabetes mellitus (GDM) is conflicting. Hence, this study set up selection criteria to include previously infertile women with PCOS but without pre-existing DM who became pregnant, aiming to minimize confounders and investigate the influence of metformin on GDM, miscarriage, and preterm delivery.

Methods: This study included 195 previously infertile women with PCOS who became pregnant.

Assessing the suitable regions and the key factors for three Cd-accumulating plants (Sedum alfredii, Phytolacca americana, and Hylotelephium spectabile) in China using MaxEnt model.

Phytoremediation is an effective way to remove metals from contaminated soil, and selecting remediation plants suitable for climate conditions is a prerequisite for effective phytoremediation. In this study, a MaxEnt model was applied to investigate the potential distribution and habitat suitability of three Cd-accumulating plants in China- Sedum alfredii, Phytolacca americana, and Hylotelephium spectabile and explore the key environmental factors that affect their habitat suitability. A total of 44 environmental parameters, including bioclimatic variables, altitude, and soil property parameters were used.

Spatial heterogeneity of human lifespan in relation to living environment and socio-economic polarization: a case study in the Beijing-Tianjin-Hebei region, China.

The spatial heterogeneity and influence factors of public lifespan have been reported worldwide at the national level or typical longevous areas. However, few sub-national studies considering the living environment and socio-economic level together have been explored in the imbalanced developed region with a huge population base and deteriorated air quality. In this paper, spatial heterogeneity of lifespan integrating environment and socio-economic influence factors was investigated in the Beijing-Tianjin-Hebei (BTH) region of China using geographically weighted regression (GWR).

Method on site-specific source apportionment of domestic soil pollution across China through public data mining: A case study on cadmium from non-ferrous industries.

The lack of emission data of major Cd-emitting enterprises has long limited the source apportionment of soil cadmium (Cd). Non-ferrous metal enterprises (NMEs) contribute the most Cd emissions in China in recent years. We estimated the cumulative Cd emission of 8750 NMEs across China through public data collection and material balance methods for the first time.

Transcriptome analysis reveals the effects of grafting on sweetpotato scions during the full blooming stages.

Background: Sweetpotato (Ipomoea batatas) is a hexaploid plant and generally most genotypes do not flower at all in sub-tropics. Heterografting was carried out between sweetpotato cultivar 'Xushu 18' and Japanese morning glory (Ipomoea nil). With sweetpotato as 'scion' and I.

The wild sweetpotato (Ipomoea trifida) genome provides insights into storage root development.

Background: Sweetpotato (Ipomoea batatas (L.) Lam.) is the seventh most important crop in the world and is mainly cultivated for its underground storage root (SR).

De Novo Transcriptome Sequencing of Oryza officinalis Wall ex Watt to Identify Disease-Resistance Genes.

Oryza officinalis Wall ex Watt is one of the most important wild relatives of cultivated rice and exhibits high resistance to many diseases. It has been used as a source of genes for introgression into cultivated rice. However, there are limited genomic resources and little genetic information publicly reported for this species.

Transcriptomic Analysis and the Expression of Disease-Resistant Genes in Oryza meyeriana under Native Condition.

Oryza meyeriana (O. meyeriana), with a GG genome type (2n = 24), accumulated plentiful excellent characteristics with respect to resistance to many diseases such as rice shade and blast, even immunity to bacterial blight. It is very important to know if the diseases-resistant genes exist and express in this wild rice under native conditions.

De novo transcriptome assembly of Ipomoea nil using Illumina sequencing for gene discovery and SSR marker identification.

Ipomoea nil is widely used as an ornamental plant due to its abundance of flower color, but the limited transcriptome and genomic data hinder research on it. Using illumina platform, transcriptome profiling of I. nil was performed through high-throughput sequencing, which was proven to be a rapid and cost-effective means to characterize gene content.

Analyses of the complete genome and gene expression of chloroplast of sweet potato [Ipomoea batata].

Sweet potato [Ipomoea batatas (L.) Lam] ranks among the top seven most important food crops cultivated worldwide and is hexaploid plant (2n=6x=90) in the Convolvulaceae family with a genome size between 2,200 to 3,000 Mb. The genomic resources for this crop are deficient due to its complicated genetic structure.

Optimal assembly strategies of transcriptome related to ploidies of eukaryotic organisms.

Background: Several de novo transcriptome assemblers have been developed recently to assemble the short reads generated from the next-generation sequencing platforms and different strategies were employed for assembling transcriptomes of various eukaryotes without genome sequences. Though there are some comparisons among these de novo assembly tools for assembling transcriptomes of different eukaryotic organisms, there is no report about the relationship between assembly strategies and ploidies of the organisms.

Results: When we de novo assembled transcriptomes of sweet potato (hexaploid), Trametes gallica (a diploid fungus), Oryza meyeriana (a diploid wild rice), five assemblers, including Edena, Oases, Soaptrans, IDBA-tran and Trinity, were used in different strategies (Single-Assembler Single-Parameter, SASP; Single-Assembler Multiple-Parameters, SAMP; Combined De novo Transcriptome Assembly, CDTA, that is multiple assembler multiple parameter).

Adjuvant effects of recombinant giant panda (Ailuropoda melanoleuca) IL-18 on the canine distemper disease vaccine in mice.

Canine distemper virus (CDV) is a morbillivirus known to cause morbidity and mortality in a broad range of animals. Giant pandas (Ailuropoda melanoleuca), especially captive ones, are susceptible to natural infection with CDV. Interleukin-18 (IL-18) is a powerful adjuvant molecule that can enhance the development of antigen-specific immunity and vaccine efficacy.
