Maternal effects shape the alternative splicing of parental alleles in reciprocal cross hybrids of Megalobrama amblycephala × Culter alburnus

Abstract: Background: Maternal effects contribute to adaptive significance for shaping various phenotypes of many traits. Potential implications of maternal effects are the cause of expression diversity, but these effects on mRNA expression and alternative splicing (AS) have not been fully elucidated in hybrid animals. Results: Two reciprocal cross hybrids following hybridization of Megalobrama amblycephala (blunt snout bream, BSB) and Culter alburnus (topmouth culter, TC) were used as a model to investigate maternal ef… Show more

“…As a result, systematic mining is very important. We found a total of 5339 alternative splicing events using SMRT RNA-seq technology, with SE (24.72 percent) and RI (21.08 percent) having the largest proportions, which was consistent with the findings of two SMRT-based fish transcriptome studies [ 31 , 37 ]. The percentage of RI events fluctuates substantially during development and is quite low during the grass carp zygotic activation (ZA) stage.…”

“…Single-molecular real-time (SMRT)-based RNA-seq has been used a lot in fish studies to look at alternative splicing events. However, these studies have mostly focused on transcriptome assembly [ 28 , 29 , 30 , 31 ] and specific study subjects [ 32 , 33 , 34 , 35 , 36 , 37 , 38 ], and they have not looked at how alternatively spliced transcripts change in expression over time in a systematic way.…”

“…Reciprocal crosses can also disentangle the contribution of each parent’s alleles to offspring phenotype [ 66 69 ]. Because we can make reciprocal crosses in S. benedicti, we are able to determine genes whose expression changes because of the parental background type alone: these are genes that have differential expression between LP and PL (Fig.…”
