Transcriptome analysis reveals the genetic basis underlying the formation and seasonal changes of nuptial pads in Rana chensinensis.

ABSTRACT:

Background

Nuptial pads, a typical sexually dimorphic trait in anurans, are located on the first digit of the male forelimb in Rana chensinensis and exhibit morphological changes synchronized with breeding cycles. However, the genetic mechanisms underlying its formation and seasonal changes remain poorly understood.

Results

To identify genes and biological processes associated with the development and seasonal variations of nuptial pads, we conducted a comprehensive transcriptome analysis on nuptial pads and hind toe skin across both sexes at different breeding periods in R. chensinensis. We identified numerous sexually and seasonally differential expression genes in nuptial pads. Notably, genes including KRT, TRY, HPDB, AKR1C1, and AKR1C3 were identified as potential key re
