Lepidagathis konkanensis sp. nov. (Acanthaceae: Barlerieae) from Lateritic Plateaus of Konkan Region of Western Ghats based on morphological and molecular evidence

open access: yesNordic Journal of Botany, EarlyView.
Lepidagathis konkanensis, a new species from the lateritic plateaus of the Konkan region in Maharashtra, India, is described and illustrated based on distinct morphological and molecular characters. Morphologically and phylogenetically, this species is close to L. mahakassapae and L. dalzelliana, but it can be distinguished by its compact inflorescence,

CLAVATA3 is a specific regulator of shoot and floral meristem development affecting the same processes as CLAVATA1 [PDF]

open access: yes, 1995
We have previously described the phenotype of Arabidopsis thaliana plants with mutations at the CLAVATA1 (CLV1) locus (Clark, S. E., Running, M. P. and Meyerowitz, E. M. (1993) Development 119, 397-418).

Taxonomy and diversity of Marcgraviaceae, north of the São Francisco river, northeast Brazil

open access: yesNordic Journal of Botany, EarlyView.
This study provides a comprehensive assessment of Marcgraviaceae species diversity north of the São Francisco river in northeastern Brazil, analyzing species richness and distribution patterns across 384 000 km² of phytogeographic domains. Through field collections, herbarium studies (both physical and digital), and detailed morphological analyses, we ...

Pollen, anther, stamen, and androecium mimicry

open access: yesPlant Biology
ABSTRACTFloral colours represent a highly diverse communication signal mainly involved in flower visitors' attraction and guidance, but also flower discrimination, filtering non‐pollinators and discouraging floral antagonists. The divergent visual systems and colour preferences of flower visitors, as well as the necessity of cues for flower detection ...

TSO1 functions in cell division during Arabidopsis flower development [PDF]

open access: yes, 1997
We describe an Arabidopsis mutant, tso1, which develops callus-like tissues in place of floral organs. The tso1 floral meristem lacks properly organized three cell layers, and the nuclei of these cells are irregular in size and shape.

A new species of Drimia Jacq. ex Willd. (Asparagaceae) from Nellai wildlife sanctuary, Western Ghats, India

open access: yesNordic Journal of Botany, EarlyView.
The new species Drimia courtallensis from the Nellai Wildlife Sanctuary of Tamil Nadu, India is described and illustrated. It is similar to Drimia razii,in its necked bulb, hysteranthous nature, lax inflorescence and diurnal flowers on moderately short pedicels but it can be distinguished by its broader linear‐lanceolate leaves (230–420 × 6–15 mm ...

Metabolomic and transcriptomic analyses jointly reveal the mechanism underlying the reddening of Chimonanthus praecox stamens

open access: yesFrontiers in Plant Science
IntroductionFlower characteristics are crucial ornamental and reproductive traits in Chimonanthus praecox. Over its long cultivation history, variations have been observed in the floral organs, primarily in the petals, with limited reports on stamen ...
