Seagrass species diversity in Tanzania based on morphological and molecular data

open access: yesNordic Journal of Botany, EarlyView.
Seagrass diversity along the Tanzanian coast has been documented mainly through morphology, with limited molecular reference data available for Tanzania and the wider Western Indian Ocean. This study combined morphological identification with nuclear ribosomal internal transcribed spacer (ITS) and plastid ribulose‐1,5‐bisphosphate carboxylase/oxygenase

Taxonomy and phylogeny of the intercontinental disjunctive ferns: series Reniformia Adiantum

open access: yesNordic Journal of Botany, EarlyView.
There are disputed opinions about the three taxa of series Reniformia, namely A. nelumboides X.C.Zhang (A. reniforme var. sinense Y.X.Lin), A. reniforme var. reniforme, and A. reniforme var. asarifolium (Willd.) R. Sim, owing to their similar morphology but intercontinental disjunctive distribution and close lineage with the series Venusta (only ...

Mazus dabieshanensis sp. nov. (Mazaceae) from eastern China

open access: yesNordic Journal of Botany, EarlyView.
Mazus dabieshanensis, a newly described species endemic to the Dabieshan Mountains in eastern China, is illustrated and described. Molecular phylogenetic analyses based on nuclear and chloroplast DNA sequences consistently demonstrate that this new species forms a stable clade with other Mazus species characterized by a pubescent ovary. Morphologically,

Genetic analysis of the rare forest bryophyte Dicranum viride in the boreo‐nemoral zone near the northern distribution range limit

open access: yesNordic Journal of Botany, EarlyView.
Bryophytes are important forest ecosystem elements, being an integral part of biodiversity. Genetic studies contribute to bryophyte population ecology by helping to understand species historical distribution patterns and genetic diversity at different scales.

Initial colonization by bryophytes and ferns during primary succession on Nishinoshima, Japan

open access: yesNordic Journal of Botany, EarlyView.
Volcanic islands that have experienced complete vegetation loss following recent eruptions provide rare opportunities to observe the earliest stages of ecosystem recovery. Nishinoshima, an oceanic island located approximately 1000 km south of mainland Japan, underwent major volcanic activity between 2013 and 2020, eradicating all pre‐existing ...

Comprehensive DIA‐MS Proteomics of Root Basal Nodes Elucidates Mechanisms of Salt Tolerance in Rice

open access: yesPROTEOMICS, EarlyView.
ABSTRACT Soil salinity severely affects rice growth, yield, and quality, posing a global food security challenge. Rice is particularly vulnerable to high salinity, which restricts growth and tolerance to other stresses. To address this, breeding efforts have been made in the past, leading to the generation of multi‐stress‐tolerant rice lines.
