Summary of phenotypic and molecular plasticity evidenced for the two studied genotypes (G1 and G2), between irrigated (IR) and non irrigated (NI) treatments
| G1 | G2 | ||
|---|---|---|---|
| IR → NI | IR → NI | ||
| Above-ground biomass | decrease | stable | |
| Transcript abundance | Hormones | + | -- |
| Secondary messengers | + (light signalling) | -- (light signalling) ++ (receptor kinases) | |
| Other stress related genes | + | -- (heat-shock proteins) ++ (PR proteins) | |
| Transcription factors | stable | ++ | |
| Cellular protection | + | -- | |
| Damages repair | + (carbohydrates secondary metabolism), | ++ (cell organisation, lipids, proteins) -- (secondary metabolism) | |
| Cellular activity maintenance | stable | -- (photosynthesis, transport) | |
Abbreviations: +/- means that in a given category more than 50% of the genes are over/underexpressed in NI.++/-- means that in a given category more than 50% of the genes are over/underexpressed in NI with a log2-tranformed fold change <-0.8 or >0.8.
