Data are scarce about the influence of basic cultural conditions on growth patterns and overall performance of plants used as heterologous production hosts for protein pharmaceuticals. Higher plants are complex organisms with young, mature, and senescing organs that show distinct metabolic backgrounds and differ in their ability to sustain foreign protein expression and accumulation. Here, we used the transient protein expression host Nicotiana benthamiana as a model to map the accumulation profile of influenza virus hemagglutinin H1, a clinically promising vaccine antigen, at the whole plant scale. Greenhouse-grown plants submitted to different light regimes, submitted to apical bud pruning, or treated with the axillary growth-promoting cytokinin 6-benzylaminopurine were vacuum-infiltrated with agrobacteria harboring a DNA sequence for H1 and allowed to express the viral antigen for 7 days in growth chamber under similar environmental conditions. Our data highlight the importance of young leaves on H1 yield per plant, unlike older leaves which account for a significant part of the plant biomass but contribute little to total antigen titer.

Federal government websites often end in. The site is secure. Nicotiana benthamiana is widely used as a model plant for dicotyledonous angiosperms. In fact, the strains used in research are highly susceptible to a wide range of viruses. Accordingly, these strains are subject to plant pathology and plant—microbe interactions. In terms of plant—plant interactions, N. Thus, N. However, N. As a result, molecular genetic analysis is difficult to perform. To improve this effort, de novo whole-genome assembly was performed in N. The 21 longest scaffolds, regarded as pseudomolecules, contained a 2. A total of 57, high-confidence gene sequences were predicted.

Other studies have described the expression of a viral proton channel to stabilize labile proteins in the cell secretory pathway Jutras et al. In this paper, we report whole-genome, n benthamiana and metabolome information for the LAB strain and the wild QLD accession, n benthamiana with single nucleotide polymorphism SNP maps for further laboratory and wild accessions. P units regroup top young leaves P1middle mature leaves P2and bottom older leaves P3 of the main primary stem, n benthamiana.

Nicotiana benthamiana , colloquially known as benth or benthi , is a species of Nicotiana indigenous to Australia. It is a close relative of tobacco. A synonym for this species is Nicotiana suaveolens var. This was transferred to Nicotiana benthamiana by Karel Domin in Bibliotheca Botanica , honoring the original author in the specific epithet. The plant was used by people of Australia as a stimulant, containing nicotine and other alkaloids , before the introduction of commercial tobacco N.

An Author Correction to this article was published on 05 January To further improve its usefulness and versatility, we have produced high-quality chromosome-level genome assemblies, coupled with transcriptome, epigenome, microRNA and transposable element datasets, for the ubiquitously used LAB strain and a related wild accession, QLD.

Unlike any other sequenced Solanaceous species genome, including the closely related diploid N. The LAB genes identified as clustering with N. The number of sequences was 1,, which was slightly higher than that of the Hifiasm primary sequence. Nicotiana benthamiana has been employed in plant pathology studies owing to its susceptibility to diverse plant diseases, particularly viral diseases. Marks, C. Science : 92— Nature Plants. In practice, recombinant protein yield in plant e. Robert, S. The expression levels of each miR and its precursor transcript were calculated from pooled data of libraries of small RNA and RNA-seq reads from this and previous studies 77 , Results Additional N. In all of these, there is evidence of recently inserted Copia elements, suggestive of their role in the process.

Nicotiana benthamiana , colloquially known as benth or benthi , is a species of Nicotiana indigenous to Australia. It is a close relative of tobacco.

Figure 5. Several plants are used as heterologous expression hosts to produce recombinant proteins of medical interest, notably including the wild relative of tobacco Nicotiana benthamiana Bally et al. The expression levels of each miR and its precursor transcript were calculated from pooled data of libraries of small RNA and RNA-seq reads from this and previous studies 77 , Methods 9 , Genome Biol. This newly assembled N. Antibodies against two active histone marks, anti-histone-H3-tri-methyl-K4 Abcam, catalogue no. Although Gypsy proliferation is obvious in the N. Marusic, C. Kommineni, V. Genes in syntenic blocks were identified as homeologues, and the genes that could not find their homoeologous partners were identified as singletons. Food Chem. The number of sequences was 1,, which was slightly higher than that of the Hifiasm primary sequence. HiC libraries were produced as described by Dong et al. Plants 2 : 1—9.
