Researchers found that a specific RNA called SUF plays a key role in determining the sex of Marchantia polymorpha plants. They discovered that when SUF is present, the plant develops as male, but by inserting a sequence into SUF, the plant can develop as female. The study highlights the importance of SUF transcription in controlling sex differentiation in M. polymorpha.
Scientists discuss the role of regulatory non-coding RNAs (ncRNAs) in the development of the liverwort Marchantia polymorpha. They highlight conserved and specific ncRNA-target modules and suggest the need for further research to understand the molecular mechanisms that control ncRNA-directed developmental processes.
Hi-C was used to study chromatin structure in Arabidopsis, tomato, maize, and Marchantia polymorpha genomes. Genes form folding domain units and neighboring genes form larger contact domains, with transcription factors binding to accessible regions contributing to gene domains and genome folding in plants.
This study compares two plant species, Marchantia polymorpha and Ceratodon purpureus, and their genetic mechanisms for sexual dimorphism. The findings suggest that different species exhibit distinct ways of controlling sexual development, which emphasizes the need for further research in understanding the evolution of sexual dimorphism.
Scientists discovered that red light decreases photosynthesis, while blue light enhances the production of secondary metabolites. Far-red light affects gene expression and morphology. These findings are valuable for studying plant responses to light and can guide future agricultural and horticultural research.
This study classified and characterized different types of extensins (hydroxyproline-rich glycoproteins) in 194 plant and algal species. It identified new crosslinking extensins and proposed an evolutionary history of these genes. This information can aid in understanding cell wall reinforcement and environmental responses in plants.
Marchantia polymorpha is a commonly studied plant in plant biology due to its potential as a new model system, aided by ease of genetic transformation and genome sequencing. The author provides a comprehensive review of the plant's anatomy and developmental morphology of each organ and tissue of the gametophyte and sporophyte through extensive literature review and observations. This research provides an important resource for future studies on Marchantia polymorpha.
