Macrobrachium rosenbergii (giant freshwater prawn; GFP) holds considerable importance in aquaculture due to its high market demand and economic significance. Female GFP growth varies significantly, however, the processes responsible for these growth disparities remain unknown. In this study, intestinal and hemolymph samples of large (FL), medium (FM), and small (FS) female GFPs were collected to investigate the molecular mechanism of female GFP growth.

- The study investigates growth differences in male giant freshwater prawns (GFP) by analyzing gut microbiota and serum metabolites, as these factors are linked to their economic importance.
- Researchers found that the dominant gut bacteria, Firmicutes and Proteobacteria, are associated with higher growth rates, particularly noting a higher Firmicutes/Bacteroides ratio in faster-growing prawns.
- The integration of transcriptomics and multiomic techniques revealed that certain metabolites, specifically butyrate, may enhance gut health and affect physiological balance, leading to variations in metabolic profiles among GFPs and improving understanding of their growth mechanisms.
Identification and characterization of olfactory gene families in Macrobrachium rosenbergii based on full-length transcripts and genome sequences.

Article Synopsis
- The study investigates the olfactory gene families in Macrobrachium rosenbergii, identifying key genes such as olfactory receptors (ORs) and chemosensory receptors (CRs) through extensive transcript sequencing.
- A total of 38,955 full-length transcripts were analyzed, resulting in the discovery of several olfactory gene family members and the first identification of CRs in prawns and shrimps.
- Additionally, the research includes the external morphology of the chemical sensory organs, providing insights into olfactory perception and potential applications in molecular breeding for crustaceans.
Myeloid differentiation factor 88 (MyD88) is a crucial adaptor protein for Toll-like receptor (TLR)-mediated signaling pathways and plays an important role in immune response. In this study, the full-length cDNA of MyD88 from Macrobrachium rosenbergii (MRMyD88) was cloned. The MRMyD88 cDNA is 1758 bp long and contains a 1398-bp open reading frame.
