Open AccessLoss of heterophylly in aquatic plants: not ABA-mediated stress but exogenous ABA treatment induces stomatal leaves in Potamogeton perfoliatus
Heterophyllous aquatic plants produce aerial (i.e., floating and terrestrial) and submerged leaves—the latter lack stomata—while homophyllous plants contain only submerged leaves, and cannot survive on land. T...

Establishment of a shortened annual cycle system; a tool for the analysis of annual re-translocation of phosphorus in the deciduous woody plant (Populus alba L.)
The supply of phosphorus, the essential element for plant growth and development, is often limited in natural environments. Plants employ multiple physiological strategies to minimize the impact of phosphate d...

Open AccessCircumnutation on the water surface: female flowers of Vallisneria
Circumnutation, the helical movement of growing organ tips, is ubiquitous in land plants. The mechanisms underlying circumnutation have been debated since Darwin's time. Experiments in space and mutant analyse...

Inherited maternal effects on the drought tolerance of a natural hybrid aquatic plant, Potamogeton anguillanus
We tested whether maternal effects have led to the adaptive divergence of strains of the natural hybrid Potamogeton anguillanus, whose putative parents show contrastingly divergent ecologies. To examine the corre...

Morphology and phylogenetic position of a mat-forming green plant from acidic rivers in Japan
A green plant, which we have named “Misuzugoke”, was found in acidic rivers in Nagano Prefecture, Japan, where it forms macroscopic mats or aggregates. The field-collected aggregates were nearly hemispherical ...

Molecular Phylogeny of the Suborder Leucodontineae (Musci; Leucodontales) Inferred from rbcL Sequence Data
sequence data (1324 bp on average). Our analyses indicate (1) that Antitrichia is distantly related to the other members of Leucodontaceae and should be excluded from the family, (2) that Cryphaeaceae form a mon...

Molecular Phylogeny of Rhizophoraceae Based on rbcL Gene Sequences
sequences to clarify the inter- and intrarelationships of Rhizophoraceae which have been variously discussed. The analyses included 12 of the 15 genera of Rhizophoraceae (4/7 of Macarisieae, 4/4 of Gynotroche...

Chromosomal Evolution in the Genus Brachyscome (Asteraceae, Astereae): Statistical Tests Regarding Correlation Between Changes in Karyotype and Habit Using Phylogenetic Information
and 8 taxa of its allied genera, Australian Astereae. Statistical tests regarding correlations between changes in chromosome number, total chromosome length, mean chromosome length, karyotypic asymmetry and c...

Chromosomal location and reorganization of the 45S and 5S rDNA in theBrachyscome lineariloba complex (Asteraceae)
The chromosomal locations of the 45S (18S-5.8S-26S) and 5S ribosomal DNA in theBrachyscome lineariloba complex and two related species have been determined by the use of multicolor fluorescencein situ hybridizati...

A molecular phylogeny of celtidaceae and ulmaceae (Urticales) based onrbcL Nucleotide sequences
On the basis of 1,290 bp sequences of the chloroplast generbcL, a molecular phylogeny of seven of nine genera of the Celtidaceae and four of six genera of the Ulmaceae was produced. These data were analyzed toget...

Intron length variation of the Adh gene in Brachyscome (Asteraceae)
Eighteen polymerase chain reaction (PCR) products of the partial sequence of the Adh (alcohol dehydrogenase) gene from 10 Brachyscome species were sequenced and compared. These products contained the 5′ three fou...

Phylogenetic relationships of some genera in the Ranunculaceae based on alcohol dehydrogenase genes
Fragments of the nuclear-encoded gene for alcohol dehydrogenase (adh) were amplified from 23 species representing 17 genera in the Ranunculaceae and one in the Berberidaceae using polymerase chain reaction method...

Morphology of the petal inAconitum
The petals ofAconitum were classified into six types. Type I: the labium tubular at the base and no appendage inside. Type II: a lambda (A)-shaped enation present inside the limb. The upper part of the enation is...
