Summary: Chitin synthesis genes typically occur in single or two copies in crustaceans, while chitin degradation genes are all multiple copies. Chitinase genes are significantly expanded in most crustacean genomes. The gene structure and expression pattern of these genes are similar to those of insects, albeit with some specific characteristics.

Summary: Chitin plays a significant role in insects, and enzymes involved in chitin metabolism are crucial for insect development and metamorphosis. Through bioinformatics analysis, we identified 54 genes encoding putative chitin metabolism enzymes in the genome of the yellow mealworm. These genes showed dynamic expression patterns during molting and were predominantly expressed in specific tissues or body parts, indicating their important roles in molting and development.

Summary: This study assessed the toxicity of lufenuron on Spodoptera frugiperda and evaluated its effects on the growth and development of the insects. The results showed that lufenuron has high insecticidal activity against S. frugiperda and can significantly prolong the larval developmental duration and reduce the rates of pupation and emergence. Gene expression analysis revealed that lufenuron treatment can significantly reduce the expression of SfCHT gene, while the expression of SfCHS gene remained relatively stable. Moreover, lufenuron strongly interacted with chitinase and chitin synthase enzymes.

Summary: AHPND is a bacterial disease caused by V. parahaemolyticus strains with a virulent plasmid encoding Pir toxin. LvDD9A and LvDD9B, cuticular proteins in shrimp, play a crucial role in preventing bacterial migration in AHPND and facilitating viral gene expression in WSSV infection. Silencing LvDD9A/B inhibits AHPND bacteria migration and decreases shrimp shell hardness, while also inhibiting WSSV gene expression and genome replication.

Summary: Partially acetylated chito-oligosaccharides (paCOSs) are bioactive compounds with potential medical applications, and their biological activities are largely dependent on their structural properties, especially the degree of polymerization (DP) and the position of acetyl groups. A newly discovered chitinase from Paenibacillus pabuli (PpChi) has been shown to produce structurally defined paCOSs with specific compositions, demonstrating stability and activity over a wide temperature range, making it a promising biocatalyst for industrial processes. When used in combination with a recently discovered fungal oxidase, PpChi significantly increases the release of oligosaccharides, contributing to the green production of valuable paCOSs with a well-defined structure.

Summary: Glycogen synthase kinase 3 (GSK3) is a highly conserved serine/threonine protein kinase that plays important roles in insulin, Wnt, and various signaling pathways. In this study, a GSK3 gene was identified in the Pacific white shrimp genome and found to be highly expressed in different developmental stages and premolting stages. Knockdown of LvGSK3 led to retarded body weight growth and altered expression of molting-related genes, highlighting its potential applications in shrimp growth.

Summary: The commercial cultivation of Litopenaeus vannamei has greatly benefited the global shrimp industry in the past decade. However, there are no academic sources supporting its commercial farming in Bangladesh, which is an important player in the global shrimp industry. The declining shrimp industry in Bangladesh, caused by the low production of traditionally cultivated black tiger shrimp and its susceptibility to diseases, calls for immediate policy measures to introduce high-yielding Litopenaeus vannamei species.

Summary: Shrimp exposed to climate change-related factors such as high temperature, hypoxia, and reoxygenation may experience oxidative stress and apoptosis. The study demonstrates the crucial role of mitochondrial manganese superoxide dismutase (mMnSOD) in preventing oxidative damage and apoptosis, while also exacerbating oxidative stress in some instances. Overall, these findings highlight the intricate response of shrimp to environmental stressors derived from climate change.

Summary: Hypoxia is a common stressor in marine environments, impacting marine species negatively. White shrimp Litopenaeus vannamei adapt to hypoxic conditions by activating tissue-specific changes in glycolytic and gluconeogenic enzymes. The control of glycolytic/gluconeogenic fluxes by fructose-2,6-bisphosphate levels and the negative regulation of PFKFBP1-2 expression in response to severe hypoxia are crucial for anaerobic glycolysis.

Summary: Transcriptional factors in bacteria, especially Bacillus species, have been extensively studied for their global interactions and effects on phenotypic levels. These factors play a crucial role in the regulation of commercial-interest metabolites production in Bacillus species. Genetic engineering of global regulators such as Spo0A, CcpA, CodY, and AbrB has shown potential for improving bioprocesses involving Bacillus species as production platforms. However, the pleiotropic effects caused by genetic modification of these regulators have not been commonly considered in the bioprocess context. This review provides an update on recent advances in this field and discusses the importance of genetic networks, regulation pathways, and their relationship to growth stages in enhancing the production efficiency of commercial-interest metabolites.

Summary: Microbial interactions in marine environments are believed to mainly rely on the exchange of organic molecules. However, our study reveals a novel inorganic route of microbial communication between algal and bacterial communities, mediated through inorganic nitrogen exchange. Aerobic bacteria reduce algal-secreted nitrite to nitric oxide (NO) via denitrification, triggering a cascade in algal cells similar to programmed cell death. The algae further generate NO during death, propagating the signal within the algal population. This exchange of inorganic nitrogen species in oxygenated environments may serve as a significant means of microbial communication across different kingdoms.

Summary: Despite little knowledge about the interrelationships among GPx isoforms in shrimp, GPx2 and GPx4 exhibit similar expression patterns during hypoxia and reoxygenation. GPx4 knock-down down-regulates GPx2 expression, suggesting that GPx4 affects GPx2 expression. Total GPx activity changes during hypoxia and reoxygenation, while GPx4 activity is unaffected by any stressor. The GSH/GSSG ratio in hepato-pancreas remains well-modulated at early hours but is impaired at 12 hours due to hypoxia and reoxygenation.

Summary: This study investigated the transfer of fatty acids from broodstock diets to eggs and the time needed for the eggs to equilibrate to the diet in Southern flounder. The findings indicate that different diet treatments significantly affect the fatty acid composition of eggs, and it takes 8-16 weeks for the eggs to adapt to changes in the adult diet. These results are important for improving broodstock diets and feeding protocols in stock-enhancement programs.
