Identification of TIFY gene family in walnut and analysis of its expression under abiotic stresses
Background: Walnuts (Juglans regia L.) are known for their nutrient-rich nuts and are one of the important economic tree species in the world. However, due to global warming and soil salinization, walnuts suffer from various abiotic stresses. TIFY (TIF[F/Y]XG) proteins play an essential role in the growth and development of plants, signal transduction, and stress response […]
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 […]
Genomic selection and genetic gain for nut yield in an Australian macadamia breeding population.
Background: Improving yield prediction and selection efficiency is critical for tree breeding. This is vital for macadamia trees with the time from crossing to production of new cultivars being almost a quarter of a century. Genomic selection (GS) is a useful tool in plant breeding, particularly with perennial trees, contributing to an increased rate of […]
Identification and analysis of the FAD gene family in walnuts (Juglans regia L.) based on transcriptome data.
Background: Walnut kernels contain a large amount of unsaturated fatty acids, such as linoleic acid and linolenic acid, which are essential fatty acids for humans and have important effects on growth and health. The main function of fatty acid desaturase (FAD), which is widely distributed in organisms, is to remove hydrogen from carbon chains in the […]
Genome-wide association studies for yield component traits in a macadamia breeding population.
Background: Breeding for new macadamia cultivars with high nut yield is expensive in terms of time, labour and cost. Most trees set nuts after four to five years, and candidate varieties for breeding are evaluated for at least eight years for various traits. Genome-wide association studies (GWAS) are promising methods to reduce evaluation and selection cycles […]
Comparison of different annotation tools for characterization of the complete chloroplast genome of Corylus avellana cv Tombul.
Background: Several bioinformatics tools have been designed for assembly and annotation of chloroplast (cp) genomes, making it difficult to decide which is most useful and applicable to a specific case. The increasing number of plant genomes provide an opportunity to accurately obtain cp genomes from whole genome shotgun (WGS) sequences. Due to the limited genetic […]
Genome-wide identification of microsatellite markers from cultivated peanut (Arachis hypogaea L.).
BACKGROUND: Microsatellites, or simple sequence repeats (SSRs), represent important DNA variations that are widely distributed across the entire plant genome and can be used to develop SSR markers, which can then be used to conduct genetic analyses and molecular breeding. Cultivated peanut (A. hypogaea L.), an important oil crop worldwide, is an allotetraploid (AABB, 2n = 4× = 40) […]
