Step by step: Floral structure and developmental changes to the formation of the gynostegium in Apocynaceae s.l.

Plant Biology, EarlyView.
Developmental changes in Apocynaceae s.l. reveal progressive reductions in the corolla tube and epipetaly, together with increased staminal tube formation, highlighting shifts in floral integration associated with gynostegium evolution and organization.

Two Auxin Response Elements Fine-Tune PINOID Expression During Gynoecium Development in Arabidopsis thaliana

Biomolecules, 2019
The plant hormone auxin controls almost all aspects of plant development through the gene regulatory properties of auxin response factors (ARFs) which bind so-called auxin responsive elements (AuxREs) in regulatory regions of their target genes.

A New Species of Myriopus (Heliotropiaceae) From Brazil

Feddes Repertorium, Volume 137, Issue 2, June 2026.
ABSTRACT A new species of Myriopus (Heliotropiaceae), Myriopus chrysocalyx J.I.M. Melo & L.G. Sá, hitherto recorded for the Brazilian Northeastern is described and illustrated. Myriopus chrysocalyx can be readily recognized by its branches strigose to villous, and, mainly, for presenting leaf blade chartaceous to subfleshy, congested inflorescences, a ...

A New and Minuscule Annual Species of Montia (Montiaceae) From Alpine Fens in Otago, New Zealand

New Zealand Journal of Botany, Volume 64, Issue 2, June 2026.
Montia minuscula Heenan is recognised as a new species from alpine habitats in Otago, South Island, New Zealand. It is currently known from only two locations, one in the Old Man Range (Kopuwai Conservation Area) and another in The Remarkables. It grows in palustrine fens that are associated with groundwater seepage such as from snowmelt and snowbanks.

Two orthogonal differentiation gradients locally coordinate fruit morphogenesis

Nature Communications
Morphogenesis requires the coordination of cellular behaviors along developmental axes. In plants, gradients of growth and differentiation are typically established along a single longitudinal primordium axis to control global organ shape.

Morphological and anatomical features of the flowers and fruits during the development of Chamissoa altissima (Jacq.) Kunth (Amaranthaceae)

Brazilian Archives of Biology and Technology, 2010
The morphology and structure of the flowers and fruits of Chamissoa altissima (Jacq.) Kunth during the development were analyzed. The plant material was fixed in FAA 50, embedded in historesin and sectioned according to standard techniques.

Phylogenetic analysis and the recognition of a new genus for Mexican Crassulaceae segregated from Echeveria

TAXON, Volume 75, Issue 3, June 2026.
Abstract Systematic knowledge of the Mexican Crassulaceae is slowly progressing as data from new DNA regions and species sampling efforts increase. We compiled and generated new rbcL, matK, rps16, ITS/ITS2, and ETS DNA sequences and performed an updated phylogenetic reconstruction for a group of 131 Mexican Crassulaceae terminals from 11 of the 13 ...

Silene, a versatile model system: from sex and genome evolution to ecology and speciation

New Phytologist, Volume 250, Issue 6, Page 3613-3630, June 2026.
Summary Fundamental and applied research in evolutionary biology benefits from the use of model systems in which approaches from disparate disciplines can be integrated. Here, we review recent progress in evolutionary research on the long‐standing model system Silene, a large genus with a well‐resolved phylogeny and newly available, expanded genomic ...

The effect of NGATHA altered activity in auxin signaling pathways within the Arabidopsis gynoecium

Frontiers in Plant Science, 2014
The four NGATHA genes (NGA) form a small subfamily within the large family of B3-domain transcription factors of Arabidopsis thaliana. NGA genes act redundantly to direct the development of the apical tissues of the gynoecium, the style and the stigma ...

‘Organ’ising Floral Organ Development

Plants
Flowers are plant structures characteristic of the phylum Angiosperms composed of organs thought to have emerged from homologous structures to leaves in order to specialize in a distinctive function: reproduction.
