Consistency of Nicotiana attenuata's herbivore- and jasmonate-induced transcriptional responses in the allotetraploid species Nicotiana quadrivalvis and Nicotiana clevelandii [PDF]

open access: yes, 2004
We examined the consistency of the native diploid Nicotiana attenuata (Na)'s herbivore-induced transcriptional changes in the two allotetraploid natives, Nicotiana clevelandii (Nc) and Nicotiana quadrivalvis (Nq), which are thought to be derived from ...

Plant-Based Vaccine Production Through Transient Expression System: A Narrative Review

open access: yesLife and Science
Transient expression systems involve the temporary expression of a foreign gene in plant tissues to enable efficient, high-yield vaccine production. Plant-based systems minimize contamination risks because the introduced gene does not integrate into the ...

In vitro grown pollen tubes of Nicotiana alata actively synthesise a fucosylated xyloglucan. [PDF]

open access: yesPLoS ONE, 2013
Nicotiana alata pollen tubes are a widely used model for studies of polarized tip growth and cell wall synthesis in plants. To better understand these processes, RNA-Seq and de novo assembly methods were used to produce a transcriptome of N. alata pollen

Phylotranscriptomics supports numerous polyploidization events and phylogenetic relationships in Nicotiana

open access: yesFrontiers in Plant Science, 2023
IntroductionNicotiana L. (Solanaceae) is of great scientific and economic importance, and polyploidization has been pivotal in shaping this genus. Despite many previous studies on the Nicotiana phylogenetic relationship and hybridization, evidence from ...

DNA methylation valley as a distinguishing feature occurs in root-specific expressed nicotine-related genes in Nicotiana attenuata

open access: yesFrontiers in Plant Science
IntroductionNicotine, the main defense alkaloid of Nicotiana species, is synthesized exclusively in the roots. Several studies have shown that changes in DNA methylation patterns are associated with altered expression of genes involved in the ...

Next generation sequencing analysis reveals a relationship between rDNA unit diversity and locus number in Nicotiana diploids

open access: yes, 2012
Background Tandemly arranged nuclear ribosomal DNA (rDNA), encoding 18S, 5.8S and 26S ribosomal RNA (rRNA), exhibit concerted evolution, a pattern thought to result from the homogenisation of rDNA arrays. However rDNA homogeneity at the single nucleotide
