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

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 ...

Cytokinin transfer by a free-living mirid to Nicotiana attenuata recapitulates a strategy of endophytic insects [PDF]

open access: yeseLife, 2018
Endophytic insects provide the textbook examples of herbivores that manipulate their host plant’s physiology, putatively altering source/sink relationships by transferring cytokinins (CK) to create ‘green islands’ that increase the nutritional value of ...

Detailed Profiling of 17-Hydroxygeranyllinalool Diterpene Glycosides from Nicotiana Species Reveals Complex Reaction Networks of Conjugation Isomers [PDF]

open access: yesMetabolites
Background: Specialised anti-herbivory metabolites are abundant in the solanaceous genus Nicotiana. These metabolites include the large family of 17-hydroxygeranyllinalool diterpene glycosides (HGL-DTGs).

NaLRR-RK4 mediates MAPK signaling to enhance plant defense against Alternaria alternata in Nicotiana attenuata [PDF]

open access: yesScientific Reports
This study investigates the role of NaLRR-RK4 in plant defense against Alternaria alternata in Nicotiana attenuata, focusing on the differential gene expression in wild-type (WT, NaLRR-RK4 expressed) and NaLRR-RK4-silenced (RNAi) plants upon inoculation.

Virus-Induced Gene Silencing Using Tobacco Rattle Virus as a Tool to Study the Interaction between Nicotiana attenuata and Rhizophagus irregularis. [PDF]

open access: yesPLoS ONE, 2015
Most land plants live in a symbiotic association with arbuscular mycorrhizal fungi (AMF) that belong to the phylum Glomeromycota. Although a number of plant genes involved in the plant-AMF interactions have been identified by analyzing mutants, the ...

Genome-wide associations of leaf spectral variation in MAGIC lines of Nicotiana attenuata. [PDF]

open access: yesEcology
Abstract The application of in‐field and aerial spectroscopy to assess functional and phylogenetic variation in plants has led to novel ecological insights and supports global assessments of plant biodiversity. Understanding how plant genetic variation influences reflectance spectra will help harness this potential for biodiversity monitoring and ...

The only African wild tobacco, Nicotiana africana: Alkaloid content and the effect of herbivory [PDF]

open access: yes, 2014
Herbivory in some Nicotiana species is known to induce alkaloid production. This study examined herbivore-induced defenses in the nornicotine-rich African tobacco N. africana, the only Nicotiana species indigenous to Africa.

Opportunistic out-crossing in Nicotiana attenuata (Solanaceae), a predominantly self-fertilizing native tobacco

open access: yesBMC Ecology, 2003
Background Although Nicotiana attenuata is entirely self-compatible, chemical and other floral traits suggest selection for the maintenance of advertisement for moth pollinators. Results Experimental exclusions of pollinators from plants with emasculated
