Trans-complementation of polyhedrin by a stably transformed Sf9 insect cell line allows occ− baculovirus occlusion and larval per os infectivity by López, María Gabriela, Alfonso, Victoria, Carrillo, Elisa Cristina, Taboga, Oscar Alberto

“…Transfection of Sf9 cells with plasmid carrying polyhedrin gene and stable cell lines established by selection with blasticidin showed polyhedrin expression and, moreover, crystalline polyhedron-like structures were visualized by optic microscopy. Oral infectivity was demonstrated by fluorescence detection in Rachiplusia nu larvae infected with occluded AcGFPpolh− baculovirus obtained using the system presented here.…”

Agriculture, food, and water nanotechnologies for the poor: Opportunities and constraints by Gruère, Guillaume P., Narrod, Clare A., Abbott, Linda

“…Nanotechnology is research and development that involves measuring and manipulating matter at the atomic, molecular, and supramolecular levels at scales measured in approximately 1 to 100 nanometers (nm) in at least one dimension.”Materials at such small scales often exhibit different electrical, magnetic, optical, mechanical, and other physical properties from their bulk material counterparts, leading to the development of potentially revolutionary technologies in a variety of industries,including agriculture and food. …”

Genome Puzzle Master (GPM)-An integrated pipeline for building and editing pseudomolecules from fragmented sequences by Zhang, Jianwei, Kudrna, Dave, Mu, Ting, Li, Weiming, Copetti, Dario, Yu, Yeisoo, Goicoechea, Jose Luis, Lei, Yang, Wing, Rod A.

“…However, these assemblies are mostly fragmented and inaccurate at the whole genome scale, largely due to the inability to integrate additional informative datasets (e.g. physical, optical and genetic maps). To address this problem, we developed a semi-automated software tool—Genome Puzzle Master (GPM)—that enables the integration of additional genomic signposts to edit and build ‘new-gen-assemblies’ that result in high-quality ‘annotation-ready’ pseudomolecules. …”
