Macadamia nut-specific IgE levels for predicting anaphylaxis.
Background: Despite the high risk of anaphylaxis in patients with a macadamia nut allergy (MdA), little is known about the significance of macadamia nut-specific immunoglobulin E (Md-sIgE). Thus, this study aimed to investigate the utility of Md-sIgE for predicting anaphylaxis. Methods: Children with suspected MdA who visited our hospital were included. MdA was defined as […]
First Report of Colletotrichum fructicola Causing anthracnose on macadamia in China.
Macadamia (Macadamia ternifolia Maiden and Betche) is an important commercial crop in the world and has the reputation of being the king of nuts (Liu et al. 2019). In August 2020, symptoms of anthracnose appeared on leaves of macadamia in Chongzuo, Guangxi Province, China, with an incidence of 15-20%. The disease developed from the edge […]
A Detection Assay to Identify Alternative Food Sources of the Two-Spotted Stink Bug, Bathycoelia distincta (Hemiptera: Pentatomidae).
The two-spotted stink bug, Bathycoelia distincta Distant (Hemiptera: Pentatomidae), is a serious pest in South African macadamia orchards. This pest is predominantly controlled using insecticides, thus alternative control methods are essential. The stink bugs arrive as adults in the orchards, during the early nut set season, but little is known about their alternative plant hosts […]
Metabolite Profiling and Transcriptome Analyses Provide Insight Into Phenolic and Flavonoid Biosynthesis in the Nutshell of Macadamia Ternifolia
Macadamia ternifolia is a dynamic oil-producing nut crop in the world. However, the nutshell is frequently considered as a low-quality material. Further, its metabolic profile is still uncharacterized. In order to explore the industrial significance of the nutshell, this study performed metabolic and transcriptomic analyses at various developmental stages of the nutshell. The qualitative and […]
Combined Transcriptome and Lipidomic Analyses of Lipid Biosynthesis in Macadamia ternifolia Nuts
Macadamia nuts are considered a high-quality oil crop worldwide. To date, the lipid diversity and the genetic factors that mediate storage lipid biosynthesis in Macadamia ternifolia are poorly known. Here, we performed a comprehensive transcriptomic and lipidomic data analysis to understand the mechanism of lipid biosynthesis by using young, medium-aged, and mature fruit kernels. Our […]
Discovery of Single Nucleotide Polymorphisms for Resistance to Abnormal Vertical Growth in Macadamia
Abnormal vertical growth (AVG) syndrome is a serious threat to the Australian macadamia industry as it decreases the yield of nuts by as much as 70% per annum. A lack of information on the cause of AVG has hindered the development of an effective disease management strategy. Discovery of genetic markers associated with disease resistance […]
The genome of the endangered Macadamia jansenii displays little diversity but represents an important genetic resource for plant breeding
Macadamia, a recently domesticated expanding nut crop in the tropical and subtropical regions of the world, is one of the most economically important genera in the diverse and widely adapted Proteaceae family. All four species of Macadamia are rare in the wild with the most recently discovered, M. jansenii, being endangered. The M. jansenii genome […]
Characterisation of novel endogenous geminiviral elements in macadamia.
Background: The presence of geminivirus sequences in a preliminary analysis of sRNA sequences from the leaves of macadamia trees with abnormal vertical growth (AVG) syndrome was investigated. Results: A locus of endogenous geminiviral elements (EGE) in the macadamia genome was analysed, and the sequences revealed a high level of deletions and/or partial integrations, thus rendering the EGE […]
Identification of vicilin, legumin and antimicrobial peptide 2a as macadamia nut allergens.
Macadamia nut is an increasingly popular food item of a healthy diet. However, macadamia nut is also a potent allergenic food. To date, there is little information about the allergenic proteins involved. In this study, using sera from macadamia nut allergic individuals, four IgE-binding proteins were detected. Their identities were determined by tandem mass spectrometry […]
Potential of Erythrocyte Membrane Lipid Profile as a Novel Inflammatory Biomarker to Distinguish Metabolically Healthy Obesity in Children.
Metabolically healthy obesity (MHO) has been described as BMI ≥ 30 kg/m2, without metabolic disorders traditionally associated with obesity. Beyond this definition, a standardized criterion, for adults and children, has not been established yet to explain the absence of those metabolic disorders. In this context, biomarkers of inflammation have been proposed as suitable candidates to […]
