Deciphering plant resilience mechanisms to face the multiple disease challenge in fruit trees

Abstract

As perennial plants, fruit trees must cope, individually, with the fluctuating threat of multiple pathogens over the years. In this long-lasting battle for plant immunity, disease resilience is emerging as a key mechanism for tree survival and fitness. More fundamental research is required to improve our understanding of disease resilience mechanisms, which in turn could be particularly relevant for a more sustainable fruit production. As this approach is novel for that field, we propose i) a clear definition of resilience for fruit producing trees, ii) a methodology for studying its phenotypic components which requires repeated measures of “resilience biomarkers”, iii) to decipher the genetic architecture of resilience components, and iv) an innovative strategy based on high-throughput phenotyping and genomics for identifying resilient genotypes. All in all, disease resilience appears as a meaningful breeding perspective in a context of unprecedented plant protection restrictions.
