Phtheirospermum (Orobanchaceae), a hemiparasitic genus of Eastern Asia, is characterized by having long and viscous glandular hairs on stems and leaves. Despite this unifying character, previous phylogenetic analyses indicate that Phtheirospermum is polyphyletic, with Phtheirospermum japonicum allied with tribe Pedicularideae and members of the Ph. tenuisectum complex allied with members of tri...

Photoreceptors are critical molecules that function at the interface between organism and environment. Plants use specific light signals to determine their place in time and space, allowing them to synchronize their growth, metabolism, and development to the environments in which they occur. Thus, innovation in light sensing mechanisms is expected to coincide with adaptation and diversification...

A new species, Melampyrum koreanum K.-J. Kim & S.-M. Yun, is described and illustrated. The new species is similar to M. roseum Maxim. in general habit, but the new species has a corolla tube and style up to 3 cm long. The new species occurs on one of the islands of the southern Korean peninsula.

Nonphotosynthetic plants possess strongly reconfigured plastomes attributable to convergent losses of photosynthesis and housekeeping genes, making them excellent systems for studying genome evolution under relaxed selective pressures. We report the complete plastomes of 10 photosynthetic and nonphotosynthetic parasites plus their nonparasitic sister from the broomrape family (Orobanchaceae). B...

6 The ability to develop invasive haustoria is the key feature of parasitic angiosperms. 7 The haustorium attaches the parasite to the host, penetrates the host while keeping 8 its own tissues intact, develops a vascular continuity between the host and parasite 9 and ultimately provides the conduit through which host and parasite materials flow. 10 The ability to make haustoria distinguishes pa...

The plant family Orobanchaceae includes many parasitic weeds that are also impressive invaders and aggressive crop pests with several specialized features (e.g. microscopic seeds, parasitic habits). Although they have provoked several large-scale eradication and control efforts, no global evaluation of their invasive potential is as yet available. We use tools from ecological niche modeling in ...

Considerable attention has been directed toward understanding the wide gaps in range that are common among many groups of closely related organisms. By placing their biology and geography in a phylogenetic context, we may gain a broader knowledge of the series of historical events that have led to present species distributions. In addition to the North American annuals, a second radiation of an...

Background: Aphyllon is a genus of 25 root-holoparasitic species restricted to the Americas. It has disjunct distribution, with 21 distributed in North America and four South America. divided into two sections: Aphyllonand Nothaphyllon. All have host-specificity, make it study model evolution holoparasitic plants. Recently, observations putative new were detected on iNaturalist.

Orobanchaceae—broomrapes—are a family of parasitic plants that represent an ecological and agronomic challenge because some them cause significant damage to many monocots or dicots. Weedy broomrapes infest different crops in the Mediterranean basin, leading substantial yield losses. Besides, they quickly adapt new host plants, so are more under threat. Control methods lacking as plant parasites...
