Codon usage bias analysis of the <i>WRKY</i> gene family in <i>Musa acuminata</i>.

ABSTRACT: Codon usage bias (CUB), a universal evolutionary phenomenon, reflects selective pressures shaping genome adaptation. The WRKY transcription factor family plays a pivotal role in regulating plant responses to physiological and biochemical stresses. This study investigates CUB patterns in 151 WRKY transcription factors of Musa acuminata 'Guijiao 9', a banana cultivar exhibiting resistance to Fusarium wilt Tropical Race 4 (TR4), to elucidate evolutionary drivers of stress adaptation. The codons of these transcription factors were selected based on their expression from RNA-Seq data. The average GC content of MaWRKY genes was 56.55%, with a GC3 content of 62.23%, indicating a preference for G/C-ending codons. Among the codons, 26 were identified as high frequency, w
