Broomrape weeds. Underground mechanisms of parasitism and associated strategies for their control: a review.

open access: yesFrontiers in Plant Science, 2016
Broomrapes are plant-parasitic weeds which constitute one of the most difficult-to-control of all biotic constraints that affect crops in Mediterranean, central and eastern Europe, and Asia.

Vestigial Plastids in Parasitic Plants: Evolutionary Remnants or Adaptive Innovations?

open access: yesPlant, Cell &Environment, Volume 49, Issue 8, Page 5401-5420, August 2026.
ABSTRACT Throughout the evolutionary history of plants, chloroplasts originating from a cyanobacterial endosymbiosis have undergone remarkable adaptation and specialization, giving rise to a multitude of plastid types. The evolution toward parasitism in plants represents a particularly extreme case of such specialization.

Comprehensive biochemical profiling of coconut haustorium for innovative food industry applications

open access: yesCyTA - Journal of Food
Coconut haustorium is a tropical delicacy that mobilizes nutrients from the endosperm to nourish the germinating embryo. This study profiles coconut haustorium for sugars, organic acids, phenolics, and flavonoids using advanced chromatographic techniques.

A Meta‐Analysis Reveals That the Protective Role of Silicon in Grasses Against Fungal Pathogens Depends on Infection Mechanism

open access: yesPlant, Cell &Environment, Volume 49, Issue 8, Page 5947-5964, August 2026.
ABSTRACT Pathogen infection drives plant community structure and constrains global agricultural productivity. Silicon (Si) improves resistance to abiotic and herbivory stress, particularly in grasses, but relatively little attention has addressed Si‐mediated resistance to pathogens, nor has it tested how this varies according to the type of plant and ...

Stoichiometric mismatches between Australian showy mistletoes and their hosts: You are what you assimilate

open access: yesEcosphere, Volume 17, Issue 7, July 2026.
Abstract Ecological stoichiometry emphasizes that mismatches between the elemental composition of organisms and their resources can shape ecological interactions, evolutionary trajectories, and nutrient cycling. For hemiparasitic plants such as mistletoes, which draw water and nutrients from hosts while maintaining their own photosynthesis, such ...

Puccinia triticina Effector Pt3863 Targets and Subverts TaRLCK176 to Suppress Wheat Resistance to Leaf Rust

open access: yesMolecular Plant Pathology, Volume 27, Issue 7, July 2026.
TaRLCK176 is a critical immune hub that positively modulates wheat resistance to leaf rust and is specifically targeted by the Puccinia triticina effector Pt3863. Notably, Pt3863 has evolved a sophisticated virulence strategy to simultaneously disrupt both the phosphorylation‐mediated activation and proteasomal stability of TaRLCK176, thereby impairing

Potential Virulence Factors in Pyrenophora teres Through Label‐Free Cellular Proteomics Analysis

open access: yesPlant Pathology, Volume 75, Issue 4, July‐August 2026.
This study presents the first label‐free proteomic profile of Pyrenophora teres, identifying potential virulence factors unique to virulent isolates. These proteins were mapped to the P. teres f. teres reference genome and previously identified virulence QTL, providing a valuable resource for future research. ABSTRACT Pyrenophora teres f.

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

open access: yesShipin 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 ...

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

open access: yesPlants, 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

Early evolutionary history of the seed

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1511-1553, June 2026.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...
