Identification and characterization of circadian clock genes in a native tobacco,
Background A plant’s endogenous clock (circadian clock) entrains physiological processes to light/dark and temperature cycles. Forward and reverse genetic approaches in Arabidopsis have revealed the mechanisms of the circadian clock and its components in

Auxin-Induced Nicotine Inhibition Is Mediated by NaARF5 Through the Suppression of NaERF1-Like Expression and Interaction With NaERF1-Like in Nicotiana attenuata. [PDF]
ABSTRACT Nicotine is the most abundant alkaloid produced by Nicotiana species against insect herbivores. Although it has been known for decades that auxin can strongly inhibit nicotine biosynthesis, the underlying mechanisms have remained unclear.

NaPDR1 and NaPDR1-like are essential for the resistance of Nicotiana attenuata against fungal pathogen Alternaria alternata [PDF]
Pleiotropic drug resistance (PDR) transporters are widely distributed membrane proteins catalyzing the export or import of a diverse array of molecules, and are involved in many plant responses to biotic and abiotic stresses.

A patatin-like protein synergistically regulated by jasmonate and ethylene signaling pathways plays a negative role in Nicotiana attenuata resistance to Alternaria alternata [PDF]
Although patatin was initially identified as a major storage protein in potato tubers, patatin-like proteins (PLPs) have been recently reported to be widely present in many plant species and shown to be involved in plant-pathogen interactions.

A jasmonate ZIM-domain protein NaJAZd regulates floral jasmonic acid levels and counteracts flower abscission in Nicotiana attenuata plants. [PDF]
Jasmonic acid is an important regulator of plant growth, development and defense. The jasmonate-ZIM domain (JAZ) proteins are key regulators in jasmonate signaling ubiquitously present in flowering plants but their functional annotation remains largely ...

Silencing JA hydroxylases in Nicotiana attenuata enhances jasmonic acid-isoleucine-mediated defenses against Spodoptera litura [PDF]
Jasmonic acid (JA) plays important roles in plant resistance to insect herbivores. One important derivative of JA is 12-OH-JA, which is produced by two independent pathways: direct hydroxylation of JA by jasmonate-induced oxygenases (JOXs) or ...

The defensin gene NaDLP1, which confers resistance against Alternaria alternata, is transcriptionally regulated by NaWRKY3/6 in Nicotiana attenuata [PDF]
Background Plant defensins are ubiquitous across plant species and serve as critical components of the innate immune system against fungal pathogens. In our previous study, we identified NaDLP1, a defensin-like protein 1-encoding gene in wild tobacco ...

A simple and efficient micrografting method for stably transformed
To adjust their development to the environment, plants rely on specific signals that travel from shoot to root and vice versa. Here we describe an efficient micrografting protocol for Nicotiana attenuata, a useful tool for identifying these signals and ...

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