Overexpression of miR399d impairs arbuscular mycorrhizal symbiosis in tomato
Summary Arbuscular mycorrhizal symbiosis (AMS) is a pervasive mutualistic interaction that is prevalent among fungi and the majority of terrestrial plant species. AMS host plants possess an alternative phosphate (Pi) acquisition pathway via arbuscular mycorrhizal fungi (AMF) in addition to direct Pi uptake by the root epidermis.

Development of chloroplast transformation for five species in the genus Nicotiana
SUMMARY Technologies for the stable genetic transformation of the plastid (chloroplast) genome are currently restricted to a small number of species. The development of highly efficient tissue culture, regeneration, and selection procedures represents the major hurdle that needs to be overcome to extend the species range of the transplastomic ...

Background Plant microRNAs (miRNAs) play key roles in the transcriptional responses to environmental stresses. However, the role of miRNAs in responses to insect herbivory has not been thoroughly explored.

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

Patterns and consequences of benzyl acetone floral emissions from Nicotiana attenuata plants
The emission of a single compound, benzyl acetone (BA, 4-phenyl-2-butanone), is barely detectable during the day in the headspace of flowers of the self-compatible disturbance species Nicotiana attenuata, but it increases dramatically (50 x) in the ...

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

Background The adage from Shakespeare, "troubles, not as single spies, but in battalions come," holds true for Nicotiana attenuata, which is commonly attacked by both pathogens (Pseudomonas spp.) and herbivores (Manduca sexta) in its native habitats ...

Specialist herbivores are known to alter their host's wound- induced responses but the beneficiaries of these alterations are unknown. Nicotiana attenuata plants release a burst of ethylene specifically in response to feeding by Manduca sexta larvae ...

Plants are at the trophic base of terrestrial ecosystems, and the diversity of plant species in an ecosystem is a principle determinant of community structure. This may arise from diverse functional traits among species. In fact, genetic diversity within
