Serine proteinase inhibitors from Nicotiana benthamiana, a non-preferred host plant, inhibit the growth of Myzus persicae (green peach aphid).

Our results show that three PIN-IIs from N. benthamiana, a non-preferred host plant, effectively inhibit M. persicae survival and growth, thereby representing a new resource for the development of aphid-resistant crop plants. This article is protected by copyright. All rights reserved.
