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.}, cin = {IBG-2}, ddc = {580}, cid = {I:(DE-Juel1)IBG-2-20101118}, pnm = {2171 - Biological and environmental resources for sustainable use (POF4-217)}, pid = {G:(DE-HGF)POF4-2171}, typ = {PUB:(DE-HGF)16}, pubmed = {39030843}, UT = {WOS:001272588100001}, doi = {10.1111/nph.19965}, url = {https://juser.fz-juelich.de/record/1035127}, }
