Transgenic rose lines harboring an antimicrobial protein gene, Ace-AMP1, demonstrate enhanced resistance to powdery mildew ( Sphaerotheca pannosa).

An antimicrobial protein gene, Ace-AMP1, was introduced into Rosa hybrida cv. Carefree Beauty via Agrobacterium-mediated transformation. A total of 500 putative transgenic plants were obtained from 100 primary embryogenic calli co-cultivated with A.
