CRABS CLAW Acts as a Bifunctional Transcription Factor in Flower Development

Frontiers in Plant Science, 2018
One of the crucial steps in the life cycle of angiosperms is the development of carpels. They are the most complex plant organs, harbor the seeds, and, after fertilization, develop into fruits and are thus an important ecological and economic trait ...

Broad Fungal Compatibility and Seed Size May Facilitate Invasiveness in Two Asian Terrestrial Orchids Spathoglottis plicata and Arundina graminifolia

Ecology and Evolution, Volume 16, Issue 6, June 2026.
Two Asian orchids, Arundina graminifolia and Spathoglottis plicata, are expanding into tropical regions worldwide, showing invasive behavior. In this study, we investigated the factors underlying their success. Both species—as all orchids—require fungal carbon to germinate, but S.

Floral nectaries in Sapindaceae s.s.: morphological and structural diversity, and their systematic implications

Protoplasma, 2017
We investigated the morphology and structure of the floral nectary in 11 Neotropical genera belonging to the subfamilies Dodonaeoideae and Paullinioideae (Sapindaceae) from southern South America representing three tribes (Dodonaeaeae, Paullinieae, and Melicocceae), in relation to other floral traits in species with contrasting morphological flower ...

The flower morphology in three Convallariaceae species with various attractive traits

Acta Agrobotanica, 2017
The general morphology and micromorphology of the flower in Polygonatum multiflorum, Maianthemum bifolium, and Convallaria majalis were studied using light microscopy methods. Among the studied species, P. multiflorum and C.

Generalist‐pollinated Arabis alpina exhibits floral scent variation at multiple scales

Nordic Journal of Botany, Volume 2026, Issue 6, June 2026.
Plants that depend on animals for reproduction often use complex floral traits to attract pollinators. Floral scent is recognized as part of the pollinator attraction module and can be shaped by plant‐pollinator interactions. In recent decades, research has started to reveal the dynamic properties of floral scent, identifying patterns of spatial and ...

Genomic Evidence Supports the Recognition of Gentianella waipara Comb. et Stat. nov. as a Distinct Species from G. calcis (Gentianaceae)

New Zealand Journal of Botany, Volume 64, Issue 2, June 2026.
Gentianella calcis subsp. waipara Glenny & Molloy (Gentianaceae) is endemic to limestone formations in North Canterbury, New Zealand. A previous conservation genetics study of G. calcis Glenny & Molloy and another eastern South Island limestone endemic species, G. astonii (Petrie) T.N.Ho & S.W.Liu, showed that G. calcis subsp.

Nectar dynamics and reproductive biology of Passiflora actinia Hook. (Passifloraceae) in Araucaria Forest

Acta Botânica Brasílica, 2018
Nectar production has an important role in pollinator attraction and successful fruit production in many self-incompatible angiosperm groups. The reproductive biology of Passiflora actinia was studied here and related to nectar dynamics.

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 ...

Ultrastructure and Function of Floral Nectaries ofChamelaucium uncinatum(Myrtaceae) [PDF]

Annals of Botany, 1996
Abstract Nectar is secreted for up to 11d after anthesis inChamelaucium uncinatum. The volume and sucrose concentration secreted varies between flowers, plants and days. The period of nectar secretion coincides with the period of pollen presentation and stigmatic receptivity suggesting nectar is part of an efficient reproductive strategy inC ...

Beyond Extrafloral Nectaries: Plant Traits as Drivers of Spider Occurrence in the Cerrado

Austral Ecology, Volume 51, Issue 6, June 2026.
ABSTRACT Patterns of predator occurrence arise from a mosaic of plant‐derived cues, yet most studies address these traits in isolation. Although extrafloral nectaries have received considerable attention, we lack a comprehensive view of how multiple plant traits jointly affect the diversity and abundance of spiders.
