Abstract
Plants maintain populations of stem cells to generate new organs throughout the course of their lives. The pathways that regulate plant stem cell maintenance have garnered great interest over the past decades, as variation in these pathways contributes plant morphological diversity and can be harnessed for crop improvement. In order to facilitate cross-species comparisons of gene function and better understand how these stem cell regulatory pathways evolved, we undertook a functionally informed phylogenetic analysis of leucine-rich receptor-like kinases (LRR-RLK) and related proteins across diverse land plant model systems. Based on our phylogenetic analysis and on functional data, we propose a naming scheme for these stem cell signaling genes. We discovered evidence for frequent loss of protein domains in angiosperms but not in bryophytes. In addition, several clades of stem cell signaling genes are closely related to genes that function in immunity, although these distinct developmental and immune functions likely separated or after the divergence of lycophytes and angiosperms. Overall, the phylogenetic framework and evolutionary hypotheses we provide here will empower future research on cross-species comparisons of stem cell signaling pathways.
