Improved knowledge of Dipsacales phylogeny provides a solid framework for studies of character evolution. Although the polarity of many characters can now be confidently established, for others it remains unclear. This results largely from uncertainty about the broader relationships of Dipsacales and is especially problematic for characters that differentiate the two basal lineages, Adoxaceae a...

Rhizophoramucronatavar.alokii (Rhizophoraceae), a new variety of Rhizophora from the Andaman and Nicobar Islands, India, is described and illustrated. The new variety is remarkable in having four stamens, laterally folded leaves, a short peduncle, thick leathery petals, and a four-sided ovary with a sessile style. A key for the species of Rhizophora of the Andaman and Nicobar Islands is also pr...

Parthenocarpic apple cultivars have been recognized with simultaneous homeotic floral organ mutations. The mutations included replacements of petals to sepals and stamens carpels, which were same as the class B organs from Arabidopsis snapdragon. For apple, parthenocarpy tightly inherited MdPISTILLATA (MdPI) gene deficiency caused However, relationship between suppression MdPI was unclear. Tran...

In a genetic screen in a drnl-2 background, we isolated a loss-of-function allele in miR319a (miR319a(129)). Previously, miR319a has been postulated to play a role in leaf development based on the dramatic curled-leaf phenotype of plants that ectopically express miR319a (jaw-D). miR319a(129) mutants exhibit defects in petal and stamen development; petals are narrow and short, and stamens exhibi...

A new species from Ecuador, Symplocos limonensis, is here described and illustrated. It resembles Symplocos clethrifolia but differs by having larger leaves with evident (i.e., not concealed) areoles on lower surface, sessile inflorescences, smaller white corollas, and fewer stamens. The species is only known from three collections in the Andean forests of Morona-Santiago Province in southern E...

We describe a locus, SUPERMAN, mutations in which result in extra stamens developing at the expense of the central carpels in the Arabidopsis thaliana flower. The development of superman flowers, from initial primordium to mature flower, is described by scanning electron microscopy. The development of doubly and triply mutant strains, constructed with superman alleles and previously identified ...

Michelia crassipes is a great ornamental plant, the flowers of which have high economic value. In this study, we employed headspace solid-phase microextraction (HS–SPME) combined with gas chromatography high-resolution mass spectrometry (GC–HRMS) for first time to identify volatile compounds emitted from different organs M. at flowering stages. flower odor comprises 69 that are dominated by ter...
