Transcriptomic responses of Solanum dulcamara to natural and simulated herbivory [PDF]

, 2017
Plants are attacked by diverse herbivores and respond with manifold defence responses. To study transcriptional and other early regulation events of these plant responses, herbivory is often simulated to standardize the temporal and spatial dynamics ...

Jasmonates and its mimics differentially elicit systemic defence responses in Nicotiana attenuata [PDF]

Journal of Experimental Botany, 2007
Coronalon (6-ethyl indanoyl isoleucine), a synthetic jasmonate mimic, is known to regulate levels of transcripts and secondary metabolites that are commonly elicited by methyl jasmonate (MeJA) in a variety of plants. The ability of coronalon and its derivative (In-L-Ile-Me) to elicit MeJA-activated transcriptional and defence responses [nicotine and ...

Benefits of jasmonate-dependent defenses against vertebrate herbivores in nature

eLife, 2016
Endogenous jasmonates are important regulators of plant defenses. If and how they enable plants to maintain their reproductive output when facing community-level herbivory under natural conditions, however, remains unknown.

Differential effects of jasmonic acid treatment of Brassica nigra on the attraction of pollinators, parasitoids, and butterflies [PDF]

, 2008
Herbivore-induced plant defences influence the behaviour of herbivores as well as that of their natural enemies. Jasmonic acid is one of the key hormones involved in both these direct and indirect induced defences.

Solar Ultraviolet-B Radiation and Insect Herbivory Trigger Partially Overlapping Phenolic Responses in Nicotiana attenuata and Nicotiana longiflora [PDF]

Annals of Botany, 2007
Plants exposed to solar ultraviolet-B radiation (UV-B, 280-315 nm) frequently suffer less insect herbivory than do plants that receive attenuated levels of UV-B. This anti-herbivore effect of solar UV-B exposure, which has been documented in several ecosystems, is in part mediated by changes in plant tissue quality.

Identification of wounding and topping responsive small RNAs in tobacco (Nicotiana tabacum) [PDF]

, 2012
Background MicroRNAs (miRNAs) and short interfering RNAs (siRNAs) are two major classes of small RNAs. They play important regulatory roles in plants and animals by regulating transcription, stability and/or translation of target genes in a sequence ...

Localized micronutrient patches induce lateral root foraging and chemotropism in Nicotiana attenuata [PDF]

Journal of Integrative Plant Biology, 2017
AbstractNutrients are distributed unevenly in the soil. Phenotypic plasticity in root growth and proliferation may enable plants to cope with this variation and effectively forage for essential nutrients. However, how micronutrients shape root architecture of plants in their natural environments is poorly understood.

High-throughput Method for Determination of Seed Paternity by Microsatellite Markers

Bio-Protocol, 2013
In this protocol, determination of seed paternity by microsatellite markers in Nicotiana attenuata is described. However, this does not include a protocol for the novel marker selection/identification, but rather exploits the markers generated for a ...

Harnessing Bulk‐Segregant Mapping to Identify Trait‐Associated Genes in the Allopolyploid Model Plant Nicotiana benthamiana

Plant Biotechnology Journal, EarlyView.
ABSTRACT Forward genetics has been instrumental in identifying genes underlying desirable traits, yet its application to polyploid plants, many of which are key agricultural crops, remains challenging due to their genomic complexity. Therefore, we developed BenthMap, a bulk segregant analysis platform for high‐throughput trait mapping and gene ...

A native plant growth promoting bacterium, Bacillus megaterium B55, rescues growth performance of an ethylene insensitive plant genotype in nature

Frontiers in Plant Science, 2012
Many plants have intimate relationships with soil microbes that through a variety of mechanisms improve the plant’s growth and fitness. Bacillus megaterium is a natural endophyte isolated from Nicotiana attenuata plant roots growing in native soils.
