Global transcriptome of Arabidopsis mutants nac42-L1 and nac42-L2 inoculated by the fungal pathogen Sclerotinia sclerotiorum following temperate and mediterranean acclimation

Plant acclimation help maintain the balance of natural systems, supporting biodiversity and the services that ecosystems provide, such as carbon sequestration and water regulation. With climate change modifying the distribution area of plants and causing more frequent and severe weather events, knowledge of how plants acclimate can inform strategies to manage ecosystems and agriculture.

Analyses of plant immune responses under abiotic constraints generally focus on pathogen inoculation under prolonged and stable abiotic conditions. Daily fluctuations of the environment may alter plant metabolism, growth and flowering as well as gene regulation and invasive growth of fungal pathogens. Yet, how plant immunity acclimates to daily temperature fluctuations remains largely unexplored.
