在植物和动物中,基因组大小通常与生活史特征相关:大基因组与较大的种子,较慢的发育,较大的身体大小和较慢的细胞分裂相关。在十足类甲壳动物中,Caridean虾在基因组大小变化和生活史特征(如幼虫发育模式和卵大小)方面都是最可变的,但这些特征在系统发育背景下的相关程度在很大程度上是未知的。在这项研究中,我们研究了卵大小,幼虫发育和基因组大小之间的相关性,在两个不同属的抢购虾,Alpheus和Synalpheus,使用遗传信息分析。在这两个Alpheus和Synalpheus,鸡蛋的大小是密切相关的幼虫发育模式:缩短发展的物种有显着较大的鸡蛋比延长幼虫发展的物种。我们制作了第一个关于Alpheus(n= 37个物种)基因组大小的综合数据集,并证明了Alpheus和Synalpheus的基因组大小与卵的大小密切相关。相关性状进化分析表明,在Alpheus中,基因组大小的变化明显依赖于卵的大小。在Synalpheus中,进化路径分析表明,发育模式的变化(从延长到缩短)驱动了卵子体积的增加;更大的卵子反过来导致更大的基因组。这些数据表明,在生殖性状的变化可能会巩固在各种各样的caridean虾groups更generally.AbstractAcross两个属的snapping虾,鸡蛋大小与基因组大小高度相关的基因组大小的变化程度。
Across plants and animals, genome size is often correlated with life‐history traits: large genomes are correlated with larger seeds, slower development, larger body size and slower cell division. Among decapod crustaceans, caridean shrimps are among the most variable both in terms of genome size variation and life‐history characteristics such as larval development mode and egg size, but the extent to which these traits are associated in a phylogenetic context is largely unknown. In this study, we examine correlations among egg size, larval development and genome size in two different genera of snapping shrimp,AlpheusandSynalpheus, using phylogenetically informed analyses. In bothAlpheusandSynalpheus, egg size is strongly linked to larval development mode: species with abbreviated development had significantly larger eggs than species with extended larval development. We produced the first comprehensive dataset of genome size inAlpheus(n= 37 species) and demonstrated that genome size was strongly and positively correlated with egg size in bothAlpheusandSynalpheus. Correlated trait evolution analyses showed that inAlpheus, changes in genome size were clearly dependent on egg size. InSynalpheus, evolutionary path analyses suggest that changes in development mode (from extended to abbreviated) drove increases in egg volume; larger eggs, in turn, resulted in larger genomes. These data suggest that variation in reproductive traits may underpin the high degree of variation in genome size seen in a wide variety of caridean shrimp groups more generally.AbstractAcross two genera of snapping shrimp, egg size is highly correlated with genome size.
