Differences in alternative splicing events in the adaptive strategies of two Daphnia galeata genotypes induced by fish kairomones.

ABSTRACT:

Background

Daphnia galeata is a suitable model organism for investigating predator-induced defense. Genes and pathways exhibiting differential expression between fish kairomone-treated and untreated groups in D. galeata have been identified. However, understanding of the significance of alternative splicing, a crucial process of the regulation of gene expression in eukaryotes, to this mechanism remains limited. This study measured life-history traits and conducted short-read RNA sequencing and long-read isoform sequencing of two Korean D. galeata genotypes (KB1 and KE2) to uncover the genetic mechanism underlying their phenotypic plasticity under predation stress.

Results

KB1 exhibited strategies to enhance fertility and decrease body length when exposed to fish kairomones,
