ABSTRACT

Abiotic stresses cause adverse effects on growth, development and productivity of plants. Plants have an inherent ability to tolerate certain levels of stress. In addition, they have the capacity to 'memorize' stressful events and protect themselves from future stresses. Furthermore, they are able to 'reset' or 'forget' memories of certain stressful situations, which helps to maximize growth after returning to non-stress conditions. A delicate balance between the consolidation of stress memory and the degree of forgetfulness is critical for plant growth and productivity under changing environmental conditions.

Our lab studies the regulatory mechanisms, both at the gene expression and protein quality control levels, by which plants alter their growth and developmental programs under stress. During my talk I will introduce transcription factors (TFs) and gene regulatory networks (GRNs) involved in the adaptation of plant growth to environmental changes by giving an example about the function of a NAC transcription factor, JUNGBRUNNEN1, in the model plant Arabidopsis thaliana and tomato. Furthermore, I will highlight our recent findings on the role of heat shock proteins and autophagy in the regulation of heat stress memory and re-setting.
