摘要: Myzus persicae (Sulzer), commonly known as the green peach aphid (GPA), is a polyphagous insect that can infest over 100 families of economically important plants and major pest for vegetable crops. This study utilizes Arabidopsis-GPA model system with aim to elucidate role plant disaccharide trehalose in providing defense against GPA. demonstrates novel TPS11 expression was found be transiently induced Arabidopsis response GPA infestation gene required curtailing infestation. TPS11, which encodes phosphate synthase phosphatase activities, contributes transient increase infested tissues. work suggests TPS11-dependent has signaling function addition, also more direct on Arabidopsis. shows able modulate both carbohydrate metabolism defenses PAD4, an phloem-based GPA, delayed tps11 mutant along increased sucrose levels lower starch compared wild type plants. provides clear evidence altered feeding TPS11-modulated curtailment
