This study generates KAI2 loss-of-function mutants in the fern Ceratopteris richardii using a CRISPR/Cas9 system and shows KAI2-dependent signaling is conserved.

The paper uses genome editing to modify a conserved noncoding sequence downstream of TAWAWA1 in rice, leading to increased panicle branching phenotypes through transcriptional upregulation of TAW1.

The paper uses snRNA-seq to analyze moss stem cells, identifying a cytokinin-ESR module that promotes pluripotent stem cell identity in the gametophore apical cell.

This study identifies KAI2-dependent signaling as a regulator of vegetative reproduction in Marchantia polymorpha by activating MpLOG-mediated cytokinin synthesis, which in turn controls GCAM1 expression.

This study shows that the common symbiotic pathway genes are essential for arbuscular mycorrhizal symbiosis in bryophytes, indicating conservation of this pathway for 450 million years.

The paper shows cytokinins are confined to pluripotent stem cells in moss, excluding the differentiation factor TAW1 to establish the shoot apical meristem from a single stem cell.
