In order to understand the evolution of the body plan characteristic of the unique aquatic Podostemaceae, seedlings of crustose-rooted species of the Hydrobryum clade, i.e., Hanseniella heterophylla, Hydrobryum loeicum, Hy. tardhuangense, Hy. vientianense and Thawatchaia trilobata, were studied by sectioning and scanning electron microscopy. In all the species the plumule/primary shoot and the radicle/primary root did not form in the seedling. The adventitious root formed exogenously from the… Expand

Two-way evolution of root form in the riverweed family Podostemaceae, with implications for phenotypic evolution
TLDR
The two-way evolution and subsequent sympatry suggests that root forms do not necessarily affect the microdistribution of the species. Expand
Origin and development of the cryptic shoot meristem in Zeylanidium lichenoides (Podostemaceae).
TLDR
ZlSTM expression demonstrated that the meristematic identity is partly retained in the embryonic shoot apex of Z. lichenoides and how it is involved in plumular leaf development in the seedling is determined. Expand
Two new genera of Podostemaceae from northern Central Laos: saltational evolution and enigmatic morphology
TLDR
Molecular phylogenetic data show that Ctenobryum mangkonense is sister to Hydrodiscus koyamae, while Laosia ramosa is distinct from all the genera in the columnar, endogenously branched axes and single style-stigma complex, pending further study. Expand
Historical biogeography of river-weeds (Podostemaceae)
TLDR
An analysis of phylogenetic relationships and comparative morphology for Podostemaceae showed that the family originated and then diverged to subfamilies Podostemoideae and Weddellinoideae in America, while the Tristichoideae most likely originated in Asia. Expand
Multidisciplinary studies of the diversity and evolution in river-weeds
TLDR
Based on field work in the four continents, many species and several genera that are new components of biodiversity are discovered, and the Podostemaceae floras of East Asia, Southeast Asia, and Australia are revealed. Expand
‘Dust seeds’ with undifferentiated embryos and their germination in mycoheterotrophic Monotropoideae (Ericaceae)
TLDR
A broad overview of dust-size seeds in angiosperms is presented and it is concluded that they should be subdivided into at least two major categories. Expand
Seed germination and early development in seedlings of Noveloa coulteriana (Podostemaceae)
TLDR
It is indicated that environmental factors such as light quality or temperature fluctuation modify seed germination of N. coulteriana and may play an important role in the reestablishment of natural populations. Expand
Life on the Rocks: First Insights Into the Microbiota of the Threatened Aquatic Rheophyte Hanseniella heterophylla
TLDR
It is concluded that aquatic plant microbiota are sensitive to anthropogenic disturbance and the potential use of this plant as biological indicators in remediation or treatment of such disturbed ecosystems is unraveled. Expand
Culture of river-weed Terniopsis chanthaburiensis (Podostemaceae)
TLDR
Podostemaceae are submerged haptophytes growing on rocks in fast currents, where no or rarely one macrophyte co-occurs, and culture was difficult, from the viewpoints of biodiversity research and conservation. Expand

We demonstrated that saltational evolution was recurrent in the body plans of seedlings of the aquatic angiosperm Podostemaceae, in contrast to other angiosperms with seedlings having almost commonExpand
Developmental anatomy of seedlings of Indodalzellia gracilis (Podostemaceae).
TLDR
It is suggested that the Indodalzellia seedling evolved by loss of the adventitious root derived from the hypocotyl, appearance of shoots in the axil of cotyledons, and appearance of adventitious roots from adventitious shoots. Expand
Comparative developmental anatomy of seedlings in nine species of podostemaceae (subfamily Podostemoideae).
TLDR
The reduced meristem morphology of seedling roots may be primitive in the Asian-Australian Podostemoideae, and similarities between the unique seedling morphology and mutant Arabidopsis phenotypes are discussed. Expand
Origin, Structure, and Interpretation of the Thallus in Hydrobryopsis sessilis (Podostemaceae)
TLDR
The Indian Podostemoideae are characterized by a dorsiventral thalloid plant body, the nature of which is controversial, and lysigeny precedes the inception of endogenous secondary vegetative shoots. Expand
Seedling developmental anatomy of an undescribed Malaccotristicha species (Podostemaceae, subfamily Tristichoideae) with implications for body plan evolution
TLDR
Comparison of the seedling development of an undescribed Malaccotristicha species and described patterns of Podostemaceae suggests that the radicle was lost in the early evolution of Podstemaceae and instead adventitious roots replaced it as a leading organ. Expand
Organ identity of the thalloid plant body of Griffithella hookeriana and Polypleurum stylosum – Podostemoideae (Podostemaceae)
TLDR
The morphological nature of the thalloid plant body of podostemads has remained controversial for long and two members of the Podostemoideae i.e. Griffithella hookeriana and Polypleurum stylosum are investigated to understand their organ identity. Expand
Structural and developmental diversity in Podostemaceae (river-weeds)
TLDR
The structural categories of typical flowering plants are transcended in the Podostemaceae due to developmental changes and saltational evolution. Expand

Phylogenetic Relationship and Morphology of Dalzellia gracilis (Podostemaceae, Subfamily Tristichoideae) with Proposal of a New Genus
TLDR
A new genus Indodalzellia is described for D. gracilis to draw attention to the remarkable morphological differences compared to the inconspicuous morphological diversity in Tristicha and Terniopsis and between the two genera. Expand
Developmental morphology of the shoot in Weddellina squamulosa and implications for shoot evolution in the Podostemaceae.
TLDR
Weddellinoideae, like Tristichoideae), have a shoot apicalMeristem, leading to the hypothesis that the meristem was lost in Podostemoideae and that the shoot apicals disappeared in the early evolution of Podostemaceae. Expand
