Convergent responses to stress. Solar ultraviolet-B radiation and Manduca sexta herbivory elicit overlapping transcriptional responses in field-grown plants of Nicotiana longiflora.
The effects of solar ultraviolet (UV)-B (280-315 nm) on plants have been studied intensively over the last 2 decades in connection with research on the biological impacts of stratospheric ozone depletion. However, the molecular mechanisms that mediate plant responses to solar (ambient) UV-B and their interactions with response mechanisms activated by other stressors remain for the most part unc...
متن کاملJasmonic acid and ethylene modulate local responses to wounding and simulated herbivory in Nicotiana attenuata leaves.
Jasmonic acid (JA) and ethylene (ET) are known to play important roles in mediating plant defense against herbivores, but how they affect development in herbivore-attacked plants is unknown. We used JA-deficient (silenced in LIPOXYGENASE3 [asLOX3]) and ET-insensitive (expressing a mutated dominant negative form of ETHYLENE RESPONSE1 [mETR1]) Nicotiana attenuata plants, and their genetic cross (...
متن کاملInduced plant defenses in the natural environment: Nicotiana attenuata WRKY3 and WRKY6 coordinate responses to herbivory.
A plant-specific family of WRKY transcription factors regulates plant responses to pathogens and abiotic stresses. Here, we identify two insect-responsive WRKY genes in the native tobacco Nicotiana attenuata: WRKY3, whose transcripts accumulate in response to wounding, and WRKY6, whose wound responses are significantly amplified when fatty acid-amino acid conjugates (FACs) in larval oral secret...
متن کاملNicotiana attenuata LECTIN RECEPTOR KINASE1 suppresses the insect-mediated inhibition of induced defense responses during Manduca sexta herbivory.
Nicotiana attenuata has the capacity to respond specifically to herbivory by its natural herbivore, Manduca sexta, through the perception of elicitors in larval oral secretions. We demonstrate that Lectin receptor kinase 1 (LecRK1) functions during M. sexta herbivory to suppress the insect-mediated inhibition of jasmonic acid (JA)-induced defense responses. Gene function analysis performed by r...
