Selection maintains floral color polymorphism in scarlet paintbrush, Castilleja coccinea, reflecting combined ecological factors

American Journal of Botany, Volume 113, Issue 1, January 2026.
Abstract Premise Evolutionary theory predicts polymorphism should be rare; however, intraspecific variation in floral color is common and can be attributed to genetic drift, plasticity, or variable selection. Examining floral color polymorphism both within contact zones and across a species' range can reveal the mechanisms maintaining this variation ...

Recent advances in Broomrapes research [PDF]

Journal of BioScience and Biotechnology, 2012
Orobanchaceae (broomrapes) is a morphologically diverse family of predominantly herbaceous, parasitic plants. The majority of species are facultative or obligate root parasites that subsist on broad-leaf plants, thereby depleting them of nutrients ...

Phelipanche cernua Pomel (Orobanchaceae), a prioritary name for the western mediterranean species recently redescribed as Ph. inexpectata [PDF]

, 2013
The specific parasite of Lactuca (Compositae) described in 2005 from the Iberian Peninsula as Phelipanche inexspectata (Orobanchaceae) and known so far in northeastern Spain and southern France, is shown to also occur in mountain areas of northern Africa,

Mowing Modulates the Biotic Filter of Expansive Species

Ecology and Evolution, Volume 16, Issue 1, January 2026.
Management type and expansive species influence plant community diversity in complex ways. Overall increase of expansive species cover acts as biotic filter in reducing the alpha and beta taxonomic and phylogenetical diversity. However, the filtering effect is modulated by management type, being more intense under mown grasslands.

‘Dispersification’ of Agalinis (Orobanchaceae) Into South America Is Associated With Hummingbird Pollination and Perennial Life‐History Shifts

Journal of Biogeography, Volume 53, Issue 1, January 2026.
ABSTRACT Aim Several mechanisms contribute to the plant biodiversity of the Neotropics, with the highlands of South America serving as important hotspots of diversity. In particular, the Brazilian highlands exhibit high biodiversity due to complex diversification dynamics and a mixture of contributions from different biomes.

Inbred‐Race Recovery From a Mixed Population of the Parasitic Weed Sunflower Broomrape (Orobanche cumana Wallr.)

Weed Research, Volume 66, Issue 1, January/February 2026.
ABSTRACT Sunflower broomrape (Orobanche cumana Wallr.) is a holoparasitic weed with two distinct genetic pools in Spain: the Guadalquivir Valley (GV) and Cuenca province (CU). From a stable situation where races F (FGV and FCU) were predominant, new races have recently emerged: GGV and GCU, presumably caused by population movements and cross ...

Trans-Specific Gene Silencing of Acetyl-CoA Carboxylase in a Root-Parasitic Plant

Molecular Plant-Microbe Interactions, 2013
Parasitic species of the family Orobanchaceae are devastating agricultural pests in many parts of the world. The control of weedy Orobanchaceae spp. is challenging, particularly due to the highly coordinated life cycles of the parasite and host plants ...
