Root apical meristem diversity in extant lycophytes and implications for root origins.
TLDR
The results support the paleobotanical hypothesis that roots evolved several times in lycophytes, as well as in euphyllophytes. Expand
Comparative anatomy of root meristem and root cap in some species of Podostemaceae and the evolution of root dorsiventrality.
TLDR
An anatomical comparison of the root apical meristems and root caps of 33 species that represent the major lineages of the Podostemaceae found evolutionary changes in the meristem preceded the specialization of external root morphologies. Expand
Developmental anatomy of Terniopsis malayana (Podostemaceae, subfamily Tristichoideae), with implications for body plan evolution
TLDR
It seems likely that the Terniopsis ramulus and its scale are comparable to the shoot and leaf, and thus a ramulus complex is interpreted as a sympodially branched shoot. Expand
Dimorphic chloroplasts in the epidermis of Podostemoideae, a subfamily of the unique aquatic angiosperm family Podostemaceae
TLDR
This work has reported the first case of the chloroplast dimorphism in a single epidermal cell of angiosperms, which suggests that the small chloroplasts mainly function in CO2 uptake for photosynthesis from torrential water. Expand
Developmental morphology of flattened shoots in Dalzellia ubonensis and Indodalzellia gracilis with implications for the evolution of diversified shoot morphologies in the subfamily Tristichoideae
TLDR
The foliose shoots of Indodalzellia and DalZellia evolved as a result of congenital fusion among several original and lateral branches, each of which grows separately in other Tristichoideae. Expand
Root apical meristem diversity and the origin of roots: insights from extant lycophytes
TLDR
Results support the paleobotanical predictions that roots evolved several times in lycophytes, as well as in euphyllophytes and discuss the origin of roots in vascular plants. Expand
Developmental Morphology of the Controversial Ramulus Organ of Tristicha trifaria (Subfamily Tristichoideae, Podostemaceae): Implications for Evolution of a Unique Body Plan in Podostemaceae
TLDR
The ramulus of Tristicha is interpreted to be the determinate shoot portion of a sympodially branched shoot system, as in Terniopsis, not as a leaf or a leaf-stem fuzzy organ. Expand
Lycopodium root meristem dynamics support homology between shoots and roots in lycophytes.
TLDR
Striking similarities in meristem dynamics provide new neobotanical data that support the shoot-origin hypothesis of lycophyte roots, which suggests that Lycopodium roots may have originated from subterranean shoots of Devonian Lycophytes, and these shoots may have changed into root-bearing axes in other extant lyCophyte lineages.

Spectroscopic studies on aquatic angiosperm
Reflectance, transmittance and absorbance spectra were observed of Hydrobryum japonicum, a kind of Aquatic angiosperm, over the wavelength range from 300 to 780 nm. Three remarkable peaks wereExpand
