AI Article Synopsis
- Moss offers a simplified model for studying plant biology due to its straightforward developmental patterns and the importance of the haploid gametophyte stage.
- The moss Physcomitrella patens has a high rate of homologous recombination, facilitating gene targeting similar to techniques used in yeast or mouse embryonic stem cells.
- With shared traits with higher plants and additional benefits, Physcomitrella patens is a promising model organism for research in plant biology and functional genomics.
Article Abstract
The potential of moss as a model system to study plant biological process is associated with their relatively simple developmental pattern and the dominance of the haploid gametophyte in the life cycle. The moss Physcomitrella patens exhibits a very high rate of homologous recombination in its nuclear DNA, making gene targeting approaches in this plant as convenient as in yeast or in ES cells of mice. Sharing many biological features with higher plants and having many other advantages, the moss Physcomitrella patens will be an attractive model system for plant biology and functional genome analysis.
