Interaction of host gene-gut microbiota in male grading of Macrobrachium rosenbergii

The giant freshwater prawn (Macrobrachium rosenbergii), a crustacean of high nutritional and economic value, is crucial for aquaculture. During the same growth cycle, males GFPs develop into three distinct forms: small males , orange claw males , and blue claw males . These morphotypes display varying social behaviors, which severely constrain their industrial development. To address this, this study collected male GFP samples at critical developmental time points for phenotypic trait measurement and analysis to obtain external morphological data. Transcriptomic analysis revealed host KEGG pathways and key genes associated with morphotype differentiation.罗氏沼虾（Macrobrachium rosenbergii）是一种兼具极高营养与经济价值的甲壳类动物，对水产养殖业至关重要。在同一生长周期内，雄性罗氏沼虾会分化为三种截然不同的表型：小雄虾、橙螯雄虾与蓝螯雄虾。这些不同表型的个体展现出差异化的社会行为，严重制约了其产业化发展。为解决这一问题，本研究于关键发育时间点采集雄性罗氏沼虾（GFPs）样本，开展表型性状测量与分析，以获取其外部形态学数据。转录组分析揭示了与表型分化相关的宿主KEGG（Kyoto Encyclopedia of Genes and Genomes）通路及关键基因。
