Understanding Plant Parasitism: Hydnora Africana and European Scientific Practice in the Early Nineteenth Century**

Berichte zur Wissenschaftsgeschichte, Volume 49, Issue 3, Page 315-334, September 2026.
This article will analyze the uncertainties around collecting and classifying Hydnora africana in the first half of the nineteenth century. Emerging from the distinctive dryland ecologies of South Africa, Hydnora was interpreted as strange and cryptic by Europeans primarily because it is a root parasite—a complex floral trait that was little understood.

The physiological anatomy of the haustorium of Striga hermonthica (Del.) Benth. (Scrophulariaceae). [PDF]

, 1992
The parasitic angiosperms are a diverse group of plants that obtain a proportion of the resources needed for growth, development and reproduction by parasitizing other flowering plants.

Harnessing plant susceptibility genes into strategies for enhanced disease resistance

New Plant Protection, Volume 3, Issue 3, September 2026.
Integrated model of S gene modules in plant pathogen interactions. This model summarises representative host susceptibility modules that can be exploited by bacterial, fungal and viral pathogens. In the bacterial infection module, Xanthomonas transcription activator‐like effectors activate OsSWEET14 through effector‐binding elements in its promoter ...

Suppression of ZmJAZ12 Expression Modulates Jasmonic Acid and Salicylic Acid Signalling and Enhances Maize Resistance to Southern Corn Rust

Molecular Plant Pathology, Volume 27, Issue 9, September 2026.
We identified ZmJAZ12 as a key susceptibility regulator that suppresses JA/SA‐mediated defence through its interaction with ZmMYC5, thereby uncovering a hormonal crosstalk mechanism governing maize resistance to southern corn rust. ABSTRACT Southern corn rust (SCR), caused by the biotrophic fungus Puccinia polysora, severely threatens maize yield ...

Tandem Kinase WTK1 Triggers Waves of Transcriptional Reprogramming Underlying Wheat Resistance to Stripe Rust

Physiologia Plantarum, Volume 178, Issue 5, September/October 2026.
ABSTRACT Tandem kinases are emerging regulators of plant immunity, but the downstream defense programs they activate remain poorly understood. Stripe rust, caused by Puccinia striiformis f. sp. tritici (Pst), is a major constraint on global wheat production. The Yr15 resistance gene, derived from wild emmer wheat, encodes the tandem kinase protein WTK1.

Phloem-Conducting Cells in Haustoria of the Root-Parasitic Plant Phelipanche aegyptiaca Retain Nuclei and Are Not Mature Sieve Elements

Plants, 2017
Phelipanche aegyptiaca parasitizes a wide range of plants, including important crops, and causes serious damage to their production. P. aegyptiaca develops a specialized intrusive organ called a haustorium that establishes connections to the host’s xylem

Hemiparasitic Castilleja presence is correlated with increased plant biodiversity across montane plant communities

American Journal of Botany, Volume 113, Issue 8, August 2026.
Abstract Premise Root hemiparasites form haustoria in belowground roots of hosts to extract nutrients and water from the surrounding hosts. Through parasitic symbiosis, these plants disproportionately affect plant communities relative to their abundance by reducing host size, altering nutrient flow, and eventually increasing local biodiversity.

Effects of Sulfated Modification on the Structural Characterization and Antioxidant Activities of Coconut (Cocos nucifera L.)Haustorium Polysaccharide

Shipin gongye ke-ji
To investigate the effect of sulfated modification on the structure and function of coconut haustorium polysaccharide (CHP), three kinds of sulfated coconut haustorium polysaccharides (SCHP-2, SCHP-3, and SCHP-4) were prepared using sulfation reagents ...

Overview of the functional virulent genome of the coffee leaf rust pathogen Hemileia vastatrix with an emphasis on early stages of infection

Frontiers in Plant Science, 2014
Hemileia vastatrix is the causal agent of coffee leaf rust, the most important disease of coffee (Coffea arabica). In this work, a 454-pyrosequencing transcriptome analysis of H.

Decoding MAPK cascades in plant immunity: Activation, regulation, integration, and pathogen manipulation

Journal of Integrative Plant Biology, Volume 68, Issue 8, Page 3000-3024, August 2026.
This review focuses on mitogen‐activated protein kinase (MAPK) activation and summarizes how plants regulate and integrate MAPK signaling in modulating plant immune responses. It also examines the effectors pathogens have evolved to manipulate MAPK activation and thereby inhibit plant immunity.
