Diversity of ferns and lycophytes in Brazil [PDF]

open access: yesRodriguésia, 2015
Abstract This compilation of ferns and lycophytes in Brazil is an update of the one published in 2010 in Catálogo de Plantas e Fungos do Brasil. The methodology consisted in collecting data from regional checklists, taxonomic revisions, and selected databases.

Complete plastid genomes from Ophioglossum californicum, Psilotum nudum, and Equisetum hyemale reveal an ancestral land plant genome structure and resolve the position of Equisetales among monilophytes [PDF]

open access: yes, 2013
BACKGROUND: Plastid genome structure and content is remarkably conserved in land plants. This widespread conservation has facilitated taxon-rich phylogenetic analyses that have resolved organismal relationships among many land plant groups.

Diversity and distribution of ferns and lycophytes in areas of restinga sandy coastal plain in south of Santa Catarina, Brazil

open access: yesRodriguésia, 2023
Ferns and lycophytes are plants often overlooked in most floristic inventories, leading to considerable gaps in the knowledge of their diversity and geographic distribution. To address this issue, we conducted a study aimed at reducing these gaps for the

Diversity and composition of ferns and lycophytes in a fragmented landscape in Ecuadorian Amazonia

open access: yesRodriguésia, 2023
Tropical forests have been subjected to increasing deforestation, leading to severe habitat loss and fragmentation of the landscape. Studies of various plant groups-indicate alteration in species diversity and assemblage composition in response to these ...

A lycophyte's plight when the light is too bright

open access: yesPhysiologia Plantarum, 2022
Plants cannot go to the store to buy sunscreen when they get too much sunlight. Instead, they use a suite of molecular processes that turn excess absorbed light energy into heat so that it can be harmlessly dissipated. These photoprotective processes collectively fall under the umbrella term “nonphotochemical quenching of chlorophyll fluorescence ...

The evolution of aluminum accumulation in ferns and lycophytes [PDF]

open access: yesAmerican Journal of Botany, 2017
PREMISE OF THE STUDY:This paper investigates the occurrence and evolution of aluminum (Al) accumulation within ferns and lycophytes, which is characterized by Al concentrations above 1000 mg·kg−1 in aboveground plant tissues. We hypothesize that this feature is more common in ferns than in angiosperms, and potentially correlated with growth form and ...

Selaginella genome analysis – entering the ‘homoplasy heaven’ of the MADS world

open access: yesFrontiers in Plant Science, 2012
In flowering plants, arguably the most significant transcription factors regulating development are MADS-domain proteins, encoded by Type I and Type II MADS-box genes. Type II genes are divided into the MIKCC and MIKC* groups. In angiosperms, these types
