Biodiversity and spatial distribution of epiphytic ferns on Alsophila setosa Kaulf. (Cyatheaceae) caudices in Rio Grande do Sul, Brazil

open access: yesBrazilian Journal of Biology
The extractive exploitation of the tree fern Alsophila setosa Kaulf. alters forest formations and diminishes the availability of micro-habitat for epiphytes. A survey of epiphytic fern communities on A.

Development of the sorus in tree ferns: Dicksoniaceae

open access: yes, 1998
Studies of soral development in the tree-fern family Dicksoniaceae in comparison with the Cyatheaceae led to (1) recognition of two basic patterns in the Dicksoniaceae, (2) clarification of marginal versus superficial sori and their indusia in tree ...

Evidence for regulation of transpiration in nonstomatal plants: insights from bryophyte gametophytes

open access: yesNew Phytologist, EarlyView.
Kinetics of cell wall water vapor potential (Ψcw) and resistance of cell wall and plasmatic membrane to water flux in response to cytoplasmic water potential (Ψcyt) during dehydration. Ψcyt was calculated from the WC at any moment of the dehydration curve by using the relationship between −1/Ψw and WC of pressure volume curves and assuming Ψw = Ψcyt ...

Nitrogen transfer from nitrogen-fixing lichen to co-occurring epiphytes in the subtropical forests of Yunnan

open access: yesGuangxi Zhiwu
Acquiring sufficient nitrogen(N)to meet requirements for growth is a major challenge for epiphytes living in nutrient-poor canopy habitats. Cyanolichens(lichens that contain cyanobacterial symbionts)can function as the primary participants in biological ...

Spatial inference of ancestor locations suggests northern refugia for canopy‐forming kelps in the Pacific Northwest

open access: yesNew Phytologist, EarlyView.
Population genetic structure in the Pacific Northwest for (a–c) Nereocystis and (d–f) Macrocystis. Summary Pockets of the formerly glaciated Pacific coastline of North America likely remained ice‐free throughout the Last Glacial Maximum (LGM). These areas may have served as refugia for terrestrial species, but less is known about their role in the ...

Conserved symbiosis‐associated genes in the cycad Encephalartos natalensis suggest co‐option for cyanobacterial symbiosis

open access: yesNew Phytologist, EarlyView.
The heterocyst‐rich Encephalartos natalensis cyanobacterial zone in coralloid root suggests co‐option of conserved symbiosis‐associated genes. This figure was created in BioRender (BioRender.com/https://BioRender.com/n3qveqc). Summary Plant‐cyanobacterial symbioses have evolved independently at least four times across land plants, yet their underlying ...

The influence of tree ferns on the composition and structure of New Zealand native forests

open access: yes, 2017
Tree ferns are an abundant, ubiquitous and conspicuous feature of New Zealand’s indigenous forests, creating shady understories and substantially contributing to litterfall, amongst other effects.

Ectopic Expression of ScALDH21 From a Desert Moss Enhances Cotton Resistance to Verticillium Wilt via the Modulation of Jasmonates and Phenylpropanoid Pathways

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Biotic stresses, particularly Verticillium wilt (VW), lead to a global decline in cotton yields. Here, we demonstrate that ectopic expression of ScALDH21, a gene from the desiccation‐tolerant moss Syntrichia caninervis Mitt. and absent in angiosperms, enhances cotton's resistance to VW.

Helechos epífitos de Alsophila setosa (Cyatheaceae, Pteridophyta) en la provincia de Misiones, Argentina

open access: yesBoletín de la Sociedad Argentina de Botánica, 2012
Los cáudices de los helechos arborescentes presentan condiciones particulares que favorecen el establecimiento de epífitas. En este trabajo se estudiaron los helechos que crecen sobre Alsophila setosa Kaulf. (Cyatheaceae, Pteridophyta) en la provincia de
