Chloroplast relocation movement in the liverwort Apopellia endiviifolia

open access: yesPhysiologia Plantarum, Volume 173, Issue 3, Page 775-787, November 2021., 2021
Abstract Changes in the subcellular localisation of chloroplasts help optimise photosynthetic activity under different environmental conditions. In many plants, this movement is mediated by the blue‐light photoreceptor phototropin. A model organism with simple phototropin signalling that allows clear observation of chloroplasts would facilitate the ...

Evolution of DELLA function and signaling in land plants

open access: yesEvolution &Development, Volume 23, Issue 3, Page 137-154, May 2021., 2021
DELLA protein evolution in land plants. DELLA protein‐encoding genes first appeared in the ancestor of land plants. There have been subsequent gene duplications in the vascular plant ancestor and in eudicot flowering plants, with gene losses in ferns and some flowering plant families.

The rise of CLAVATA: evidence for CLAVATA3 and WOX signaling in the fern gametophyte. [PDF]

open access: yesPlant J
SUMMARY CLAVATA3/EMBRYO SURROUNDING REGION (CLE) peptides are 12–13 amino acid‐long peptides that serve as positional signals in plants. The core CLE signaling module consists of a CLE peptide and a leucine‐rich repeat receptor‐like kinase, but in flowering plants, WUSCHEL‐RELATED HOMEOBOX (WOX) transcription factors are also incorporated to form ...

Three overlooked species of Bacidia from insular Laurimacaronesia

open access: yesNordic Journal of Botany, Volume 39, Issue 3, March 2021., 2021
We discuss the taxonomy of three species of Bacidia occurring in insular Laurimacaronesia. Two of them, B. amylothelia (Vain.) Vain. and B. endoleucoides (Nyl.) Zahlbr., which were previously described from Angola and Madeira, respectively, are found here to belong in Bacidia s. str. (Ramalinaceae).

Involvement of Auxin Biosynthesis and Transport in the Antheridium and Prothalli Formation in Lygodium japonicum

open access: yesPlants, 2021
The spores of Lygodium japonicum, cultured in the dark, form a filamentous structure called protonema. Earlier studies have shown that gibberellin (GA) induces protonema elongation, along with antheridium formation, on the protonema.

Lepraria juanfernandezii , a new lichen species from the Southern Hemisphere

open access: yesPlant and Fungal Systematics, 2019
Lepraria juanfernandezii is described as a new species. It differs from all other species of Lepraria by its aggregate thallus with sparse prothallus hyphae, the absence of a hypothallus, the presence of divaricatic acid and the absence of zeorin, and

RESEARCHES CONCERNING THE IN VITRO DIFFERENTIATION OF THE FERN PHEGOPTERIS CONNECTILIS (MICHX.) WATT

open access: yesNotulae Botanicae Horti Agrobotanici Cluj-Napoca, 2007
Phegopteris connectilis is an apogamous species, endangered in certain regions. The ex situ conservation, through the in vitro production of the gametophyte, as well as the embryos and the plants, followed by their cryo-stocking, is necessary for ...

Study of the independent gametophytes found on Jeju Island in South Korea and the first record of the obligate independent gametophyte of Antrophyum obovatum Baker

open access: yesEcology and Evolution, Volume 10, Issue 14, Page 7826-7838, July 2020., 2020
This work is about independent gametophytes in Korea. However, we found the independent gametophyte, Antrophyum obovatum, which is firstly reported in this study. Abstract Fern gametophytes have often been neglected in research; however, studies on gametophytes are crucial for a better understanding of the evolution of ferns.

Systematic studies in the genus Mohria (Anemiaceae: Pteridophyta). IV. Comparative gametophyte morphology in Mohria and Anemia

open access: yesBothalia: African Biodiversity & Conservation, 1993
The sporophyte morphology in Mohria and Anemia (Anemiaceae) is dissimilar. However, similarities in their anatomy, trichomes, spores and chromosome numbers show clearly that these genera are related.

In Vitro Development of Gametophyte and Sporophyte in Several Fern Species

open access: yesNotulae Botanicae Horti Agrobotanici Cluj-Napoca, 2008
The in vitro differentiation of the gametophyte and sporophyte of Pteridophyta, conducted through the culture, on nutritive media, of the green, incompletely differentiated sporangia and spores, exhibits a variety of peculiarities. Whereas in the case of
