- Observation Spring and control Plantago plants differed significantly in phenotypic plasticity for above-ground biomass, leaf size and epidermal cell size.
- Observation Spring and control Plantago plants differed significantly in phenotypic plasticity for epidermal cell number and stomatal density and index.
- Observation Gene expression responses to elevated CO2 (acclimation) were modest, with 33-131 differentially expressed genes.
- Observation Gene expression differences between control and spring plants (adaptation) were considerably larger, with 689-853 DE genes.
- Mechanism Plantago plants are adapted to their native CO2 environment at the level of gene expression.
- Intervention effect Stomatal index increased in spring plants but not control plants under elevated CO2.
- Association Stomatal patterning gene expression was altered between spring and control plants at three loci (YODA, CDKB1;1 and SCRM2).
- Association Stomatal patterning gene expression was altered between ambient and elevated CO2 at four loci (ER, YODA, MYB88 and BCA1).
- Mechanism SCRM2 and CDKB1;1, when upregulated, may be key controllers of stomatal adaptation to elevated CO2.
- Observation Spring plants showed significant transcriptome reprogramming of photosynthesis and dark respiration.
- Observation Spring plants showed enhanced growth.
