The function of NaPNRP in Nicotiana attenuata growth promotion stimulated by Piriformospora indica
Zusammenfassung der Projektergebnisse
The results presented in this project study have unraveled the important role that HSPRO has in the control of early N. attenuata seedling growth stimulated by the growth-promoting fungus P. indica. Since the effect on growth was only observed when ir-hspro seedlings were colonized by this fungus, and HSPRO expression was induced by multiple stressassociated stimuli, the results suggested that HSPRO plays an important role in growth and/or metabolism readjustment during stress responses. Although speculative, the control over metabolism during insect herbivory could involve the regulation of resource partitioning between shoots and roots and its resulting consequences in the interaction of roots with soilborne microbes. The results opened new hypotheses on how this control may be achieved, and the interaction of HSPRO with components of the SnRK1 complex appears as one potential scenario. Future work will focus on the disentangling of the HSPRO-dependent mechanisms underlying the regulation of growth/metabolism during stress responses.
