Which opera composed by Richard Wagner did influence Giuseppe Verdi?

Giuseppe Verdi was not influenced by any of Richard Wagner's operas. While Wagner's operas had a profound impact on the development of opera as a genre, Verdi's musical style and approach to opera remained largely distinct from Wagner's. Verdi's operas are known for their focus on melody, dramatic intensity, and strong emotional expression, while Wagner's operas are characterized by their complex musical textures, leitmotifs, and integration of music and drama.
