Abstract The mirid bug Apolygus lucorum has become a major agricultural pest since the large-scale cultivation of Bt-cotton. It was assumed that A. lucorum, similarly to other phloem sap insects, could secrete saliva contains effector proteins into plant interfaces perturb host cellular processes during feeding. However, secreted effectors are still uncharacterized and unstudied. In this study, 1878 putative were identified from transcriptome which either had homology with published aphid or...

Abstract Background Rabies remains a devastating and fatal infectious disease worldwide. To date, vaccination is the most reliable effective strategy for controlling rabies. However, despite effectiveness of inactivated vaccines, cumbersome procedures high costs post-exposure prophylaxis impose significant economic burden, particularly in developing countries with limited access to vaccines. Therefore, there an urgent need develop novel rabies vaccine that reduces while enhancing safety...

Riptortus pedestris (Fabricius) is a polyphagous hemipteran crop pest that mainly feeds on the leguminous plants, resulting in shriveled and dimpled seeds. With recent several outbreaks Huang-Huai-Hai region of China, as well South Korea Japan, this species has caused enormous economic losses to soybean crops. In present study, we found R. feeding results local lesions at infestation sites. To identify key effectors induce plant damage during feeding, salivary glands were dissected for...

Plants deploy various immune receptors to recognize pathogen-derived extracellular signals and subsequently activate the downstream defense response. Recently, increasing evidence indicates that endoplasmic reticulum (ER) plays a part in plant response, known as ER stress-mediated immunity (ERSI), halts pathogen infection. However, mechanism for stress response of infection remains unclear. Here, we characterized regulator NAC089, which was previously reported positively regulate programed...
