miRNA profiling responding to water submergence in A. philoxeroides. a) The phenotypes of upland and water‐logged A. philoxeroides at different time points. The left side displays the overall growth phenotypes, while the right side shows the morphology of the second internode. Scale bars are shown. b) Overall levels of miRNAs in young stems (internodes 1 & 2) and old stems (internodes 3 & 4) under different conditions. The fold changes of miRNA levels were calculated relative to 0 h. Data are presented as mean ± standard errors (SE). c) Volcano analysis showing typical differentially expressed miRNAs in stems at different time points after submergence. The red dots represent upregulation, while the blue dots represent downregulation, and the gray dots indicate no change.

Phenotypic flexibility in adaptive traits is crucial for organisms to thrive in changing environments. Alternanthera philoxeroides, native to South America, has become an invasive weed in Asia. The mechanism by which invasive capacity is achieved remains unknown. Here, it is demonstrated that miR162 plays a crucial role in submergence survival for...
