We characterized new transgenic varieties of poplar with multiple insect-resistant and salt stress tolerant genes. Two insect-resistant Bacillus thuringiensis (Bt) genes, Cry1Ac and Cry3A, and a salt-tolerant gene, Betaine aldehyde dehydrogenase (BADH) were inserted into a vector, p209-Cry1Ac-Cry3A-BADH. The clone of Populus x euramericana was transformed by the vector using the Agrobacterium-m...

In this study, two fungal strains (HC-Z1 and HC-Z2) from Hyphantria cunea (fall webworm) larvae were evaluated for their potential as biocontrol agents against the H. larvae. Based on morphological molecular (ITS1-5.8S-ITS2 region) characterization, identified Beauveria bassiana (HC-Z1: OP415530 HC-Z2: OP415531). To determine biological activities of strains, a concentration-response assay (1 ×...

Amerikan beyaz kelebeği, Hyphantria cunea Drury (Lepidoptera: Erebidae) dünyada önemli bir karantina zararlısıdır. Polifag zararlı olan H. cunea, başlıca meyveler, orman ağaçları ve süs bitkilerinde ekonomik kayıplara neden olmaktadır. Zararlının larvaları yapraklar üzerinde beslenerek yaz sonunda sonbaharda ağaçların dallarında karakteristik ağdan örülmüş büyük yuvalar oluşturmaktadır. Bu çalı...

Host range factor 1 (HRF-1) of Lymantria dispar multinucleocapsid nucleopolyhedrovirus promotes Autographa californica MNPV replication in nonpermissive Ld652Y cells derived from L. dispar. Here we demonstrate that restricted Hyphantria cunea NPV replication in Ld652Y cells was not due to apoptosis but was likely due to global protein synthesis arrest that could be restored by HRF-1. Our data a...
