The moss P.patens has been used as a versatile experimental model organism for the past 80 years and it falls in the division Bryophyta. Being relatively simple in morphology and it generates only few tissues that contain limited number of cell fates (Mark leech et al., 1993), it is extensively being undertaken by plant biologists on both basic and applied strategies covering major areas namely developmental biology, evolution, systems biology, biotechnology ,biodiversity etc., As the organism is predominantly haploid in nature, it is evident that it could allow to develop insights on straight forward investigation/understanding of plant systems and hence, it is amenable for genetic and molecular level studies (Cove., 2009). The availability of complete genome sequence information, genetic and physical map ease the utilization of P.patens in all most all the fields of biology (Yasuko Kamisugi., 2008). It is the only land plant with an efficient system of homologous recombination in its nuclear DNA by which specific gene targeting could be achieved and the strategy of loss of function mutants can be generated by RNAi approach. In this context, the functional genomics of P.patens helps in identifying novel genes which could be employed in metabolic engineering and stress tolerance like drought, salt and osmotic stress thus helps in improving the crop plant performance. Moreover, it serves as a valuable platform for the production of recombinant pharmaceuticals (Anna K. Beike., 2010) Thus, the transfer of novel genes from P.patens has a greater biotechnological impact and may help in better public acceptance. Hence, this presentation aims to confine the advantages of this model plant in plant molecular research by discussing its efficiency in reproduction, range of technologies applied, some interesting characteristic features behind this model and chosen case studies will establish the model behaving as a well-versed medium for wide variety of approaches
