Knocking Out Two Polyphenol Oxidase Genes Significantly Improves Recombinant Protein Purification in Nicotiana benthamiana

Plant Biotechnology Journal, EarlyView.
ABSTRACT Efficient purification remains a key technical challenge affecting the recovery efficiency of recombinant proteins in plant‐based systems. Complex metabolites, particularly polyphenols, often cause recombinant protein aggregation during purification.

Alteration of Product Specificity of Rhodobacter sphaeroides Phytoene Desaturase by Directed Evolution [PDF]

Journal of Biological Chemistry, 2001
Phytoene desaturases occurring in nature convert phytoene to either neurosporene or lycopene in most eubacteria. Approximately 10% of known phytoene desaturases, as in Rhodobacter, produce neurosporene, whereas the rest produce lycopene. These two types of enzymes, although similar in function, have relatively low similarity (below 60%) in terms of ...

ERF Transcription Factor NaERFIDOG Regulates JA‐Induced Defence and Growth Inhibition in Nicotiana attenuata Upon Alternaria alternata Infection

Plant Biotechnology Journal, EarlyView.
ABSTRACT Jasmonate (JA) regulates defence responses in plants. However, JA‐induced defence often results in growth inhibition. This process is largely mediated by MYC2, the master regulator of JA signalling. Nevertheless, the underlying molecular mechanisms have not yet been fully uncovered.

Single genetic locus improvement of iron, zinc and β-carotene content in rice grains

Scientific Reports, 2017
Nearly half of the world’s population obtains its daily calories from rice grains, which lack or have insufficient levels of essential micronutrients. The deficiency of micronutrients vital for normal growth is a global health problem, and iron, zinc and

Integrated Metabolomic and Transcriptomic Analysis Revealed the Capsanthin Biosynthesis and Sequestration in Processing Type Red Pepper (Capsicum annuum var. conoides)

eFood, Volume 7, Issue 4, August 2026.
This study establishes that fruit color divergence in Yanjiao pepper cultivars arises from hierarchical regulation of carotenoid metabolism, driven by yellow‐blue chromaticity variation and cultivar‐specific metabolic strategies. These findings provide a mechanistic framework for breeding peppers with enhanced color stability and nutraceutical value ...

Immunocytochemical localization and functional determination of phytoene desaturase in photoautotrophic prokaryotes [PDF]

Journal of General Microbiology, 1990
Summary: The in situ location of phytoene desaturease, an enzyme in the carotenoid biosynthetic pathway, has been investigated in the photosynthetic organisms Rhodobacter capsulatus SB 1003, Synechocystis PCC 6714, and Anabaena variabilis ATCC 29413.

Effect of diflufenican on total carotenoid and phytoene production in carrot suspension-cultured cells

, 2019
Main Conclusion: Diflufenican increased 493-fold the level of phytoene. Diflufenican-induced inhibition of phytoene desaturase gene expression in carrot cells resulted in an increased production of phytoene. This work analyzes the effect of diflufenican,

Thirty years of glyphosate‐resistant crops and weeds: Current situation and future prospects

Pest Management Science, Volume 82, Issue 7, Page 5987-6009, July 2026.
Since 1996, when the first glyphosate‐resistant crop was commercialized and the first resistant weed was reported, resistance has expanded globally. This review analyzes emergence patterns across weed species, crops, regions, resistance mechanisms, and herbicides.
