AkWRKY38 and AkWRKY53 exhibited high expression levels in Amorphophallus konjac under hormone treatments, Pcc infection, and abiotic stresses including low temperature, drought, and salt stress.
WRKY family members were identified in four Araceae species, with 79 in Amorphophallus konjac, 57 in Amorphophallus albus, 59 in Zantedeschia elliottiana, and 36 in Spirodela intermedia.
Segmental duplication was the primary driving force for expansion of the WRKY gene family in these Araceae species, with Ka/Ks less than 1 suggesting purifying selection.
AkWRKY genes exhibit tissue-specific expression patterns in leaves, petioles, corms, and roots, and most genes are up-regulated during developmental stages 2 to 3 of the corm.
Most Araceae WRKY members belong to Group II.
Most WRKY members contained the conserved heptapeptide WRKYGQK domain within their motifs.
Fourteen AkWRKY genes showed significantly differential expression under ABA, JA, SA, Pectobacterium carotovorum subsp. carotovorum infection, low temperature, drought, and salt stress.
