Morphological and micromorphological characteristics of Desmodium fruits (Leguminosae: Papilionoideae)

Revista de Biología Tropical, 2014
The genus Desmodium is represented in Santa Catarina State, Brazil, by 13 species, all with lomentaceous fruits. Shape, size and isthmus margin of loments vary, while the surface is glabrous, or covered by trichomes of different types.

Identification of a novel link connecting indole‐3‐acetamide with abscisic acid biosynthesis and signaling

New Phytologist, Volume 249, Issue 5, Page 2452-2466, March 2026.
Summary Plants orchestrate their developmental processes and responses to environmental stimuli through a sophisticated network of small signaling molecules, termed phytohormones. Among these, auxins are recognized for their role in promoting plant growth.

Revisiting the relationship between stomatal size and speed across species – a meta‐analysis

New Phytologist, Volume 249, Issue 5, Page 2338-2354, March 2026.
Summary The rate of stomatal opening and closure in response to changes in light affects leaf photosynthesis and water use. However, it is unclear how strongly stomatal size (SS) and density (SD) influence stomatal conductance (gs) kinetics, and whether variation arises from methodological differences, guard cell type or degree of amphistomaty.

Phylogenomics reveals the evolution of floral traits associated with pollinators and pollinator–prey conflict within the carnivorous Pinguicula subgenus Temnoceras

American Journal of Botany, Volume 113, Issue 2, February 2026.
Abstract Premise The carnivorous plant genus Pinguicula (Lentibulariaceae) exhibits remarkable floral diversity associated with pollination, particularly in the largest subgenus Temnoceras, which spans Mexico and Central America. Despite this diversity, the relationships between species and the evolution of key floral traits remain unresolved. Here, we

Attraction of Bucephalogonia xanthophis (Hemiptera: Cicadellidae) to volatiles of its natural host Vernonia condensata (Asteraceae) Atratividade de Bucephalogonia xanthophis (Cicadellidae) por voláteis de seu hospedeiro atural Vernonia condensata (Asteraceae)

Scientia Agricola, 2008
Plant volatiles are important cues for the orientation of herbivorous insects. It is possible that these compounds indicate whether the plant is suitable for feeding and larval development, or for mating aggregation.
