A New Hexaploid Species of Isoetes (Isoetaceae) From Fujian, China, Based on Morphological and Molecular Evidence [PDF]

open access: yesEcology and Evolution
A new endemic species of Isoetes from Fujian, China, which was previously identified as I. orientalis, is described and illustrated. In this study, we observed its leaf cross‐cut characteristics under a microscope and spore morphology characteristics ...

Underwater CAM photosynthesis elucidated by Isoetes genome [PDF]

open access: yesNature Communications, 2021
Despite extensive characterization of crassulacean acid metabolism (CAM) in terrestrial angiosperms, little attention has been given to aquatics and early diverging land plants. Here, the authors assemble the genome of Isoetes taiwanensis and investigate

Insights into cryptic speciation of quillworts in China [PDF]

open access: yesPlant Diversity, 2023
Cryptic species are commonly misidentified because of high morphological similarities to other species. One group of plants that may harbor large numbers of cryptic species is the quillworts (Isoëtes spp.), an ancient aquatic plant lineage. Although over

Comparative chloroplast genome and transcriptome analysis on the ancient genus Isoetes from China [PDF]

open access: yesFrontiers in Plant Science, 2022
Isoetes is a famous living fossil that plays a significant role in the evolutionary studies of the plant kingdom. To explore the adaptive evolution of the ancient genus Isoetes from China, we focused on Isoetes yunguiensis (Q.F. Wang and W.C. Taylor), I.

Phylogeny of Merlin’s grass (Isoetaceae): revealing an “Amborella syndrome” and the importance of geographic distribution for understanding current and historical diversity [PDF]

open access: yesBMC Ecology and Evolution, 2022
Background Merlin’s grass (Isoetes, Isoetaceae, Lycopsida), is the extant remnant of the isoetalean wood-producing lycopsids that originated during the Paleozoic, possibly in aquatic or boggy habitats.

Organellar-genome analyses from the lycophyte genus Isoetes L. show one of the highest frequencies of RNA editing in land plants [PDF]

open access: yesFrontiers in Plant Science
RNA editing is a post-transcriptional process that challenges the central dogma of molecular biology by modifying RNA sequences, introducing nucleotide changes at specific sites, and generating functional diversity beyond the genomic code, especially ...
