The evolution of land plants is tightly linked to the evolution of the alternation of generations. Because alternating ploidal generations share their genomes, investigating generation-biased gene expression can give insight into the evolution of life cycles in land plants. Toward this end, we describe gene expression differences associated with the alternation of isogenic sporophyte and gameto...
This work aimed to recognize the reproductive biology of the epiphytic bryoflora of phorophytes of Virola surinamensis (Rol. ex. Rottb.) Warb. in várzea and igapó forests in the Caxiuanã National Forest, to answer the following question: The reproductive period of the bryophyte species is influenced by the environment due the climatic seasonality present in flooded forests, being higher the occ...
Dispersal is a key step in land plant life cycles, usually via formation of spores or seeds. Regulation of spore- or seed-germination allows control over the timing of transition from one generation to the next, enabling plant dispersal. A combination of environmental and genetic factors determines when seed germination occurs. Endogenous hormones mediate this decision in response to the enviro...
