abstract = {Amphicarpy is an unusual trait where two fruit types
develop on the same plant: one above and the other
belowground. This trait is not found in conventional model
species. Therefore, its development and molecular genetics
remain under-studied. Here, we establish the allooctoploid
Cardamine chenopodiifolia as an emerging experimental system
to study amphicarpy. We characterized C. chenopodiifolia
development, focusing on differences in morphology and cell
wall histochemistry between above- and belowground fruit. We
generated a reference transcriptome with PacBio full-length
transcript sequencing and analysed differential gene
expression between above- and belowground fruit valves.
Cardamine chenopodiifolia has two contrasting modes of seed
dispersal. The main shoot fails to bolt and initiates floral
primordia that grow underground where they self-pollinate
and set seed. By contrast, axillary shoots bolt and develop
exploding seed pods aboveground. Morphological differences
between aerial explosive fruit and subterranean nonexplosive
fruit were reflected in a large number of differentially
regulated genes involved in photosynthesis, secondary cell
wall formation and defence responses. Tools established in
C. chenopodiifolia, such as a reference transcriptome, draft
genome assembly and stable plant transformation, pave the
way to study amphicarpy and trait evolution via
allopolyploidy.},
