"New Frontiers in Bryology" is a specialized book that explores the diversity and unique characteristics of mosses (Bryophyta, Musci). These plants are not only widespread but also attractive models for experimental research due to their ease of cultivation and rapid generation time. Notably, the haploid gametophyte phase allows for the relatively simple isolation of developmental mutants. The book highlights the ability of mosses to tolerate extreme environmental conditions and compares these traits with other plant species, such as Arabidopsis thaliana. A significant advancement in plant biology discussed in this work is the efficient homologous recombination in the moss species Physcomitrella patens, which offers unique opportunities for the functional analysis of plant genes. The development of a global community of moss researchers and the organization of conferences on this topic are also addressed, underscoring the relevance and dynamism of research in this field.
