En el presente trabajo se actualiza rango de distribución del género Physcomitrium en la Argentina. El tratamiento incluye revisión taxonómica tres especies reportadas para noroeste país, P. lorentzii, subsphaericum y thieleanum que caracterizan por las cápsulas simétricas erectas, cupuladas a urceoladas gimnostomas, inmersas o exertas caliptra mitrado- rostrada. Se presentan 2 claves taxonómic...

Although being recognized as a major force behind speciation in flowering plants, the evolutionary relevance of genome duplication (polyploidization) remains largely unexplored mosses. Phylogenetic and-genomic insights from model organism Physcomitrella patens and closely related species revealed that polyploidization, likely via hybridization (allopolyploidization), gives rise to new within Fu...

The calyptra is a maternal structure that protects the sporophyte offspring from dehydration, and positively impacts sporophyte survival and fitness in mosses. We explore the relationship between cuticle protection and sporophyte height as a proxy for dehydration stress in Funariaceae species with sporophytes across a range of sizes. Calyptrae and sporophytes from four species were collected fr...

A new paradigm has slowly emerged regarding the diversification of bryophytes, with inferences from molecular data highlighting a dynamic evolution their genome. However, comparative studies expressed genes among closely related taxa is so far missing. Here we contrast dimensions vegetative transcriptome Funaria hygrometrica and Physcomitrium pyriforme against genome relative, (Physcomitrella) ...
