Jasmonate signalling in plants



Roberto Solano

Group Leader



Research summary

We are interested in understanding how plants are able to perceive changes in their environmentand integrate stress signals with their internal developmental programs, to induce adaptive responses and survive in nature. This integration depends on complex signalling networks that regulate the genetic reprogramming of the cell. The main focus of my lab is to understand one of the pathways involved in this network, the jasmonate(JA) signalling pathway, in plants.

Fig 1Jasmonates (JA) are fatty acid-derived signalling molecules essential for the survival of plants in nature, since they are important activators of stress responses and developmental programmes. The main focus of my laboratory is to understand the JA signalling pathway in plants, knowledge that is essential for designing biotechnological and agronomical applications that improve plant resistance to stresses and plant yield. We have worked traditionally in the model plant Arabidopsis thaliana, but recently focused on the liverwort Marchantia polymorpha. We are using Marchantia for evolutionary studies as well as a model system in basic research due to its low gene redundancy. The major achievements of our group in the last two years have been:

  • Identification of a new family of transcription factors (YABBY) regulating responses to JA (Boter et al., Plant Cell 2015)
  • The demonstration that the COI1-JAZ2-MYC2,3,4-ANAC19,55,72 module regulates stomatal aperture in leaves. This module is hijacked by bacteria using the JA-mimic coronatine to open stomata and promote infection. This discovery provides novel strategies for crop protection against biotrophs without compromising resistance to necrotrophs (Giménez-Ibáñez et al., New Phytol 2016).
  • We participated in the analysis of the genome of Marchantia polymorpha (Bowman et al.,under review) and in defining the gene nomenclature in this species (Bowman et al., Plant Cell Physiol 2016).
  • We also established numerous collaborations with other groups that have elucidated the function of MYB & ZML genes in maize (Velez-Bermudez et al., Plant Cell 2015), the role of jasmonates in carnivory feeding (Böhm et al., Curr Biol 2016), the regulation of JAZ12 by KEG (Pauwels et al., Plant Physiol 2015) and contributed to identifying the DNA sequence target of plant transcription factors using previously developed tools (Raines et al., Plant J 2016; Medina-Puche et al., Plant Physiol 2015; Baud et al., Plant Physiol 2016).
