The control of pests that attack our crops is one of the major challenges and costs in agriculture today. It is predicted that the importance of arthropod pests will increase as a result of global warming and that new problems will arise from the emergence of novel pests into agroecosystems. In this context, the main objective of our group is to decipher how plants recognize and respond to a particular herbivore attack and how climate change affects these interactions. To identify genes, proteins and molecules with potential use to control pests is an additional goal.

1. Deciphering plant defence responses to pest infestations.

Our current plant-pest model is formed by the plant Arabidopsis thaliana and the phytophagous arthropod Tetranychus urticae. In addition, crop species as tomato, bean and brassicas are also host pest targets used in our research. The two-spotted spider mite T. urticae is a cosmopolitan agricultural acarian, considered one of the most significant agricultural threats since it has a short life cycle, high offspring production and an extraordinary ability to develop pesticide resistance. It feeds on over 1,100 documented host plants, 150 of them of agricultural importance. Spider mites pierce individual mesophyll parenchymatic cells using stylets to suck their nutrients without damaging epidermal cells. They produce severe chlorosis and the consequent reduction in crop yield. Our research tries to decode the plant defence responses (genes, signalling pathways, molecules and hormonal regulation) that confer resistance to mites and to apply the knowledge gained through basic science as a potential new avenue for pest control, and in parallel, to understand the differential ability of mites to feed on a wide plants hosts. To determine factors that contribute most to crop success/failure within the changing agricultural ecosystem is essential to develop strategies to mitigate pest damage and increase plant performance. Our team, within the GAP-M consortium (Genomics in Agriculture Pest Management), participates in the development of genomic and histological tools derived from the plant-spider mite interplay, including whole genome sequences and annotations of T. urticae and databases for transcriptome and metabolome responses in both, plant and mite, sides of the interaction (Santamaria et al. 2012; 2013; 2015; 2018; Zhurov et al. 2014; Martel et al. 2015; Ojeda-Martinez et al., 2020; 2021). Besides, our group has identified and characterized some plant genes as candidates for pest control in the reciprocal whole genome studies in plant-pest interactions (Santamaria et al. 2013; 2017; 2018; 2019; Arnaiz et al. 2018; 2019, 2021).

Tetranychus uticae feeding on bean



Recently, we have expanded our scope to other arthropod herbivores. Starting from a set of 28 Arabidopsis-herbivore transcriptomic experiments, we performed a bioinformatics comprehensive analysis to discover novel pathways involved in the response of the plant to T. urticae (Santamaria et al., 2021), as well as to disentangle specificities and commonalities in plant/pest interactions (Garcia et al., 2021). These results are highly relevant to understand step by step the whole pathway, from the herbivore detection, the signal transduction or the hormonal related crosstalk, to culminate in specific plant defence responses. The analysis of the perception, signalling and transmission of alarms between cells and to other parts of the damaged plant is currently the main focus of our research. The final goal is to understand how plants (models and crops) respond to herbivory.

2. Understanding the effects of environmental conditions on plant-pest interactions.

It is predicted that the importance of pests will increase as a result of global warming and that new pest problems will arise from the introduction of invasive species into agroecosystems as well as emergence of novel pests that had minor significance previously. Temperature and water availability associated with Climate change are expected to have profound effects on the plant-herbivore interactions. These intricate interactions can be dissected only using novel technologies that can relate interactions at the genome and metabolome level as a function of climate change parameters and linking them to fitness outputs for these organisms. This knowledge will permit to dissect the molecular effects of climate factors on the plant/herbivore interactions and to develop new tools for an efficient and environmentally-friendly pest management under conditions of changing climate.

Experimental design to decipher the effect of increased temperatures on plant-pest interactions



The Arabidopsis/T. urticae pair is a good starting model because of under increased temperatures and drought stress associated with climate change, Tetranychidae species shorten their life cycle, produce more generations per year and appears earlier in the season and on a wider range of hosts. Our group has determined the role of several pathways and genes in the interaction of Arabidopsis plants with spider mites, covering different aspects including plant perception, signal transduction and end responses (reviewed in Santamaria et al., 2020). To a better understanding of the molecular pathways, our analyses will be extended to a second herbivore, the insect Pieris brassicae, and to crop plants such are Solanum lycopersicum, Brassica rapa and Phaseolus vulgaris. In this context, our main goals are to know how the molecular signalling is modified upon a particular herbivore attack and how climate change affects these interactions.
