The transition of plants from aquatic to terrestrial environments occurred approximately 400 million years ago, leading to the diversification of two major lineages: tracheophytes (vascular plants) and bryophytes (non-vascular plants). While most studies on plant adaptation to environmental stressors…

The regulated expression of genes is fundamental to all biological processes, including development, cell growth, and responses to environmental signals. Transcription factors (TFs) are sequence-specific DNA-binding proteins that play a central role in transcriptional regulation by directly interacting…

Gametogenesis is essential for sexual reproduction. In bryophytes, lycophytes, and ferns, gametogenesis takes place in gametangia: antheridia for sperm production and archegonia for egg production. How these specialized reproductive organs develop at the molecular level remains unclear. Furuya et al.…

Marchantia’s power as a model organism continues to grow! Here, Ramoni et al. have investigated the expression pattern of the proximal promoters of most of its 450 transcription factor (TF)-encoding genes. The promoter elements were fused to nuclear-localized fluorescent reporters and introduced into…

Humans and flowering plants spend most of their lives in a diploid state with two copies of each chromosome in most cells, but to reproduce they produce haploid gametes through meiosis. By contrast, bryophytes (liverworts, hornworts, and mosses), spend most of their lives in the haploid state. They produce…

Precise control of cell division is an important requirement for proper development in multicellular organisms. Rho-like GTPases from Plants (ROPs) are key conserved regulators of cell polarity and morphogenesis, however, it is unknown if ROP signaling pathways regulate cell division patterning and meristem…
