Integrated Transcriptome and Metabolome Analysis Reveals Insights into Flavone and Flavonol Biosynthesis in Salicylic Acid-Induced Huanglongbing Tolerance.

Salicylic acid (SA) exhibits positive effects against Huanglongbing (HLB), but how SA affects citrus resistance to HLB is currently unknown. This study conducted integrated transcriptome and metabolome analyses on SA-treated (HLB-sensitive) and (HLB-tolerant). The results indicated that the syntheses of flavones and flavonols were induced by SA, while the expression levels of associated genes and the contents of corresponding metabolites varied significantly between the two species after SA treatment or HLB infection.

Microbial community of cultivated and uncultivated citrus rhizosphere microbiota in Brazil.

The rhizosphere microbiome is known to contain beneficial microorganisms that promote plant growth and increase tolerance to abiotic and biotic stresses. Understanding citrus microbiome diversity and the percentage of diversity that can be recovered in the laboratory is essential for developing innovative approaches to improve plant health and promote sustainable agricultural practices. However, information about the citrus root microbiome, especially in the context of exploring commercial citrus growing areas to identify beneficial plant growth-promoting rhizobacteria (PGPR), is scarce.

Seasonal effects on multiparous dairy cow behavior in early lactation.

Controlled studies have shown that heat stress abatement positively influences health, productivity, behavior, and reproductive performance of dairy cows during all stages of the lactation cycle. Based on previous findings, the present study focused on a better understanding of how seasonal changes affect the behavior of multiparous lactating dairy cows kept in typical free-stall housing with the objective to aid in the management of lactating cows exposed to variable environmental conditions. Automated monitoring devices (Nedap, the Netherlands) were used to assess behavioral activity of mature Holstein dairy cows during the "hot season" (HS; n = 19; July, August, and September) and the "cool season" (CS; n = 15; December, January, and February) under normal management conditions.

Global citrus root microbiota unravels assembly cues and core members.

Introduction: Citrus is one of the most important fruit crops worldwide, and the root-associated microbiota can have a profound impact on tree health and growth.

Methods: In a collaborative effort, the International Citrus Microbiome Consortium investigated the global citrus root microbiota with samples collected from nine citrus-producing countries across six continents. We analyzed 16S rDNA and ITS2 amplicon sequencing data to identify predominant prokaryotic and fungal taxa in citrus root samples.

Dissection of transcriptional events in graft incompatible reactions of "Bearss" lemon () and "Valencia" sweet orange () on a novel citrandarin () rootstock.

Citrus is commercially propagated via grafting, which ensures trees have consistent fruit traits combined with favorable traits from the rootstock such as soil adaptability, vigor, and resistance to soil pathogens. Graft incompatibility can occur when the scion and rootstock are not able to form a permanent, healthy union. Understanding and preventing graft incompatibility is of great importance in the breeding of new fruit cultivars and in the choice of scion and rootstock by growers.

Sustainable seedling pots: Development and characterisation of banana waste and natural fibre-reinforced composites for horticultural applications.

Plastic pots used in horticultural nurseries generate substantial waste, causing environmental pollution. This study aimed to develop biodegradable composites from banana pseudo-stem reinforced with agricultural residues like pineapple leaves, taro and water hyacinth as eco-friendly substitutes. The aim of this study is to develop optimised banana biocomposite formulations with suitable reinforcements that balance mechanical durability, biodegradation, and seedling growth promotion properties to serve as viable eco-friendly alternatives to plastic seedling pots.

TOMMicroNet: Convolutional Neural Networks for Smartphone-Based Microscopic Detection of Tomato Biotic and Abiotic Plant Health Issues.

The image-based detection and classification of plant diseases has become increasingly important to the development of precision agriculture. We consider the case of tomato, a high-value crop supporting the livelihoods of many farmers around the world. Many biotic and abiotic plant health issues impede the efficient production of this crop, and laboratory-based diagnostics are inaccessible in many remote regions.

Encapsulated lignin-based slow-release manganese fertilizer with reduced cadmium accumulation in rice (Oryza sativa L.).

As an essential trace element for plant growth and development, manganese plays a crucial role in the uptake of the heavy metal cadmium by rice (Oryza sativa L.). In this study, we developed a novel slow-release manganese fertilizer named Mn@LNS-EL.

Daily olive oil intake is feasible to reduce trigeminal neuralgia facial pain: A pilot study.

Extra virgin olive oil (EVOO) is thought to contribute to neuroprotection and, thus, may influence pain symptoms experienced by adults with demyelination-related trigeminal neuralgia (TN). This study aimed to determine the feasibility of daily intake of EVOO and its potential to alleviate facial pain of TN. Adults, self-reporting as female and affected by TN, were enrolled in a 16-week nonblinded, parallel study.

Identification of ethyl vanillin in strawberry (Fragaria × ananassa) using a targeted metabolomics strategy: From artificial to natural.

Improving flavor can be an important goal of strawberry through breeding that is enhanced through the accurate identification and quantification of flavor compounds. Herein, a targeted metabolomics strategy was developed using liquid-liquid extraction, an in-house standard database, and GC-MS/MS analysis. The database consisted of key food odorants (KFOs), artificial flavor compounds (AFCs) and volatiles.

Assessing Gastrointestinal Tolerance in Healthy Adults: Reliability and Validity of a Weekly Questionnaire.

When examining gastrointestinal tolerance to nondigestible carbohydrates, a weekly vs. daily symptoms questionnaire may lessen participant burden. This secondary analysis examined the reliability and validity of the Gastrointestinal Symptom Rating Scale (GSRS) in healthy adults.

Physical Activity Compliance to American Cancer Society Recommendations Amongst Hematopoietic Stem Cell Transplant Survivors.

Background And Objectives: The aims of this study were to determine the extent to which hematopoietic cell transplantation (HCT) survivors adhere to the American Cancer Society recommendations for weekly physical activity and identify potential demographic and transplant characteristics associated with the lack of compliance.

Methods: This cross-sectional study included adults who had undergone HCT and were at least 1 year post transplantation. Physical activity was assessed using the screening tool of the Block 2014.

Wood-derived bio-coating materials incorporating hydrophobic lignin and hierarchically porous biochar for high-efficiency coating slow-release fertilizers.

Coating slow-release fertilizers (CSRFs) have gained significant attention for their potential to improve nutrient utilization efficiency and prevent environmental pollution through mitigating soil and water contamination. This study developed a novel wood waste-derived composition as a bio-coating material for urea slow-release by integrating modified lignin (PCL) and activated biochar (ABC). PCL was prepared by grafting palmitoyl chloride (PC) with hydrophobic groups to the lignin via an esterification reaction.

Unraveling the mystery of canopy dieback caused by citrus disease Huanglongbing and its link to hypoxia stress.

Devastating citrus disease Huanglongbing (HLB) is without existing cures. Herein, we present results demonstrating the possible mechanisms (hypoxia stress) behind HLB-triggered shoot dieback by comparing the transcriptomes, hormone profiles, and key enzyme activities in buds of severely and mildly symptomatic 'Hamlin' sweet orange (). Within six months (October - May) in field conditions, severe trees had 23% bud dieback, greater than mild trees (11%), with a concomitant reduction in canopy density.

Laboratory evaluation of the life history of hibiscus mealybug, Nipaecocus viridis (Hemiptera: Pseudococcidae), on selected citrus and potential non-citrus hosts in Florida.

Nipaecoccus viridis (Newstead) (Hemiptera: Pseudococcidae) is an emerging invasive pest of citrus. There is no information on the life history of N. viridis in relation to citrus cultivars produced in Florida.
