Could photoperiodic responses have evolved before the emergence of circadian clocks?

New Phytologist, EarlyView.
Summary Plants use photoperiod (i.e. day length) as a seasonal cue for timing when to flower. This ability, known as photoperiodism, also underlies phenomena such as migration, seasonal reproduction, and hibernation in animals. Because a circadian (daily) clock underlies the day/night length timing mechanism in most organisms, it has been generally ...

Red Alga Porphyridium Supports High‐Yield Production of a Functional Chimeric Hepatitis B Surface Antigen With Strong Cellular and Humoral Immunogenicity

Plant Biotechnology Journal, EarlyView.
ABSTRACT Microalgae represent promising production factories for the light‐driven, cost‐effective production of recombinant proteins. The red microalga Porphyridium purpureum displays particularly favourable transgene expression properties due to the episomal maintenance of transformation vectors at high copy numbers in the nucleus.

Engineering Conditional Transgene Expression in Nicotiana benthamiana

Plant Biotechnology Journal, EarlyView.
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
