Summary: The study in Singapore found that barramundi farmed in sea cages are undergoing precocious sex change, with a decrease in male individuals and an increase in females as early as 2-3 years old. This phenomenon challenges hatcheries in selecting and maintaining male fish for breeding purposes, and further investigation is needed to understand the causes of this early sex change.

Summary: With global population growth and negative impacts of climate change on crop production, current agricultural practices cannot meet the increasing food demand. Therefore, more careful breeding efforts are needed to develop plants that are better adapted and tolerant to climate fluctuations. Fortunately, molecular biology techniques such as genome, transcriptome, and epigenome sequencing provide new approaches to assist classical breeding. This review focuses on the potential of epigenetic approaches, specifically the creation of epigenetic markers, in guiding the selection process in breeding programs.

Summary: Rainbow trout lines with different spawning seasons were crossed to study the impact on spawning date and gamete characteristics of offspring. The hybrid progeny showed a later spawning date and exhibited a classic phenotypic distribution pattern of heterozygous F1 hybrids. The study provides valuable information for hatchery production of year-round seedstock and genetic analysis of spawning date in rainbow trout.

Summary: The study evaluated metal concentrations in different organs of Barramundi fish and found that heavy metal concentrations were higher in farmed fish than in wild fish, possibly due to environmental conditions and dietary element concentrations. Although some metal concentrations exceeded national and international threshold limits, overall, all studied heavy metals were below the maximum permissible limits.

Summary: Fish meal is a limiting factor for fish feed development. The use of forage fish as a protein source in fish feed is unsustainable and hinders the aquaculture industry. Researchers have explored alternative protein sources, such as food industry by-products and local raw materials. This study found that most echinoderm species are unpalatable for barramundi fish and should not be recommended as an ingredient in barramundi feed.

Summary: Grafting is a valuable agricultural technique that enhances the performance of horticultural plants. Molecular signals, such as proteins and RNA, are transferred between the scion and rootstock during grafting. Recent studies suggest that grafting can lead to epigenetic alterations, which have been shown to impact gene expression and plant function.

Summary: This study evaluates the potential of environmental RNA (eRNA) released by macroeukaryotes as a biomonitoring tool. The results show that eRNA can be filtered from water and reliably provide species composition information through metabarcoding analysis. Compared to eDNA, eRNA has a higher true positive rate, making it a promising addition to the suite of molecular monitoring tools.

Summary: This study investigated the effects of dietary restriction and subsequent re-alimentation on body composition and hepatic gene expression in postpubertal beef bulls. The results showed that the metabolic status had a significant impact on regulating hepatic epigenetic mechanisms, such as DNA methylation and histone acetylation, which modulate gene transcription. Body fat changes during periods of undernourishment and compensatory growth had a greater influence on epigenetic markers related to gene transcription than on markers related to gene translation. This study provides new insights into the molecular changes in the liver of bulls in response to diet and body weight fluctuation.

Summary: Chia, an emerging industry crop with high content of omega-3 fatty acids and dietary fiber in its seeds, lacks polymorphic and codominant DNA markers for genetic analysis. This study identified and characterized fourteen polymorphic microsatellites in chia, revealing low genetic variation among cultivars from Mexico, Australia, and Bolivia. The findings suggest that a breeding program for chia should incorporate seeds from multiple cultivars to increase genetic variation.

Summary: In this study, the physiological responses and underlying mechanisms of oil palm to salt stress were investigated using RNA-Seq analysis. The results showed that salt stress activated the expression of EgSPCH gene and increased stomatal density in oil palm. Additionally, several differentially expressed genes were found to be involved in salt response-related bioprocesses. Overexpression of EgSPCH in Arabidopsis resulted in increased stomatal production and decreased salt tolerance.

Summary: Drought stress is a significant environmental hazard, and plants respond to it differently. C3 and C4 plants exhibit different cellular responses to drought, which may be associated with the divergent expression of their SPEECHLESS genes. Our research investigated the drought tolerance of C3 and C4 plants through gene expression analysis and stomatal assay under drought stress.

Summary: Aquaculture is crucial for global food security. Developing species and varieties of omnivorous fish that can tolerate high salinity will enhance fish production. Certain tilapia species, such as Oreochromis mossambicus and Oreochromis aureus, are highly tolerant to salinity and have been used in aquaculture production in brackish and seawater. Different breeding methods, both conventional and molecular, have been implemented to improve the growth rate and salinity tolerance of tilapia. Advances in genomic resources and disruptive technologies provide optimism for novel breeding approaches to further enhance the production of salinity-tolerant tilapia.
