The current scenario of climate change, water scarcity and high temperatures are two of the adverse environmental conditions that are most likely to increase their incidence in the coming years. Apart from their direct detrimental effects on crop development and productivity, these conditions also affect the biotic environment, thus increasing the damage inflicted by pests.

In this context, a research team from the Universitat Jaume I led by Vicent Arbona and Miguel González Guzmán, Ramón y Cajal researcher, both from the Biochemistry and Molecular Biology Area, has obtained, within the Spanish Plan for Scientific and Technical Research and Innovation 2017-2020, a project to investigate the response mechanisms against the simultaneous incidence of water stress, high temperatures and mite infestation in cultivated tomatoes. In addition, traits derived from wild tomatoes that can provide greater tolerance to these stresses will be identified.

The project, with funding of 187,550 euros, will use populations of wild tomato introgression lines in the cultivated tomato genome that will be characterised to identify the most tolerant lines and their connection to specific molecular, hormonal and metabolic changes.

These changes will be further analysed through co-expression network analysis, which will identify gene hubs potentially involved in transcriptional and metabolic reprogramming, modulating, connecting or interacting with different hormonal signalling pathways.
