Engineering Conditional Transgene Expression in Nicotiana benthamiana

Plant Biotechnology Journal, Volume 24, Issue 1, Page 18-30, January 2026.
ABSTRACT Nicotiana benthamiana has emerged as a premier plant biofactory for recombinant protein and metabolite production due to its high metabolic versatility, ease of cultivation and permissiveness to transient expression vectors. However, challenges such as transgene silencing, low yields and metabolic toxicity limit its scalability. Synthetic gene

Role of the Photorhabdus Dam methyltransferase during interactions with its invertebrate hosts.

PLoS ONE, 2019
Photorhabdus luminescens is an entomopathogenic bacterium found in symbiosis with the nematode Heterorhabditis. Dam DNA methylation is involved in the pathogenicity of many bacteria, including P.

The loss of the urea cycle and ornithine metabolism in different insect orders: An omics approach

Insect Molecular Biology, Volume 34, Issue 5, Page 632-644, October 2025.
Among urea cycle enzymes, only the nitric oxide synthase gene is universally present across insect genomes. All Hemiptera species lack the enzymes needed to convert citrulline to arginine, and some also lack the pathway from arginine to ornithine. Putrescine and spermidine synthesis is conserved in all insects, but aphids lack the capability to produce

Eco-friendly management of Spodoptera litura (Lepidoptera: Noctuidae) in tomato under polyhouse and field conditions using Heterorhabditis bacteriophora Poinar, their associated bacteria (Photorhabdus luminescens), and Bacillus thuringiensis var. kurstaki

Egyptian Journal of Biological Pest Control, 2023
Background Insect pests cause substantial agriculture losses annually, and their regulation through chemical pesticides instigates a prolonged detrimental impact on the environment and human health.

Bacterial Glutamine Synthetases as a Novel Metabolic Selection Marker to Improve CHO Cell Culture Performance Through Selection Stringency Modulation

Biotechnology Journal, Volume 20, Issue 9, September 2025.
Graphical Abstract and Lay Summary Metabolic selection markers have improved stable cell line generation by enhancing productivity without relying on antibiotics. This study evaluated bacterial glutamine synthetases as novel selection markers in CHO cells, identifying variants that significantly increased antibody titers and revealed structural ...

Serratia spp. bacteria evolved in Aotearoa‐New Zealand for infection of endemic scarab beetles

New Zealand Journal of Zoology, Volume 52, Issue 2, Page 121-143, June 2025.
ABSTRACT The Melolonthinae branch of the beetle family Scarabaeidae has evolved in isolation in Aotearoa, radiating into >100 endemic species, since Aotearoa separated from Gondwanaland 82 million years ago. The group includes important pasture pests, such as the New Zealand grass grub Costelytra giveni and the manuka beetle Pyronota festiva.

Photox, a Novel Actin-targeting Mono-ADP-ribosyltransferase from Photorhabdus luminescens [PDF]

Journal of Biological Chemistry, 2010
Photorhabdus luminescens is a pathogenic bacterium that produces many toxic proteins. The mono-ADP-ribosyltransferases (mARTs) are an enzyme class produced by numerous pathogenic bacteria and participate in disease in plants and animals, including humans. Herein we report a novel mART from P. luminescens called Photox.

Engineered Living Energy Materials

Interdisciplinary Materials, Volume 4, Issue 3, Page 412-455, May 2025.
Engineered living energy materials (ELEMs) are nascent research frontier for enabling sustainable energy conversion and storage. These materials exhibit unique characteristics such as self‐regeneration, biodegradability, environmental response, and evolutionary adaptability. This paper overviews different energy conversion bio‐modules, summarizes their

A zinc metalloprotease inhibitor, Inh, from the insect pathogen Photorhabdus luminescens [PDF]

Microbiology, 2002
The entomopathogen Photorhabdus luminescens secretes many proteins during the late stages of insect larvae infection and during in vitro laboratory culture. The authors have previously characterized and purified a 55 kDa zinc metalloprotease, PrtA, from culture supernatants of P. luminescens.
