Endogenous RALF peptide function is required for powdery mildew host colonization

New Phytologist, Volume 251, Issue 4, Page 2073-2090, August 2026.
Model of RALF‐FER‐dependent effects on powdery mildew sporulation. Summary The receptor kinase FERONIA (FER) is a susceptibility factor for biotrophic powdery mildew fungal pathogens in Arabidopsis thaliana, but the underlying molecular mechanisms remain largely unknown. FER is required for the perception of endogenous RAPID ALKALINIZATION FACTOR (RALF)

Proteomic Analysis of Plasmodesmata From Populus Cell Suspension Cultures in Relation With Callose Biosynthesis

Frontiers in Plant Science, 2018
Plasmodesmata are channels that link adjacent cells in plant tissues through which molecular exchanges take place. They are involved in multiple processes vital to plant cells, such as responses to hormonal signaling or environmental challenges including

A Non‐Host Pathogen Elicitor Induces Blast Resistance Mediated by OsNAC78‐Pir7b Module in Rice

Plant, Cell &Environment, Volume 49, Issue 8, Page 4894-4906, August 2026.
ABSTRACT Plants exhibit broad‐spectrum and persistent resistance induced by non‐host pathogens. Previous studies have found that syringolin A secreted by Pseudomonas syringae pv. syringae can activate the expression of defense‐related gene Pir7b in non‐host rice, but the underlying mechanism remains ambiguous.

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

Plant, 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 ...

The Role of Callose Deposition Along Plasmodesmata in Nematode Feeding Sites

Molecular Plant-Microbe Interactions, 2010
Infective second-stage juveniles of the obligate plant-parasitic root-knot and cyst nematodes invade plant roots to induce specialized feeding structures.

Chemical treatment rescues reduced growth of the autoimmune mutant chs3‐2D without compromising its immune responses

Plant Biology, Volume 28, Issue 5, Page 1686-1697, August 2026.
We generated a compound by chemical modification that can efficiently rescue growth without decreasing the immune response of the chs3‐2D autoimmune mutants, thus chemically uncoupling its growth–defence trade‐off. Abstract Plant development in many species including Arabidopsis relies on the accurate balance between growth and defence.

Systemic infection of tobacco mosaic virus is limited by upward transport and phloem unloading without coat protein

The Plant Journal, Volume 127, Issue 3, August 2026.
SUMMARY Coat protein (CP) is widely viewed as essential for systemic infection of tobacco mosaic virus (TMV), yet the mechanistic basis of this requirement remains incompletely resolved. In this study, we show that TMV can still achieve long‐distance vascular transport in the absence of CP, but systemic infection becomes intermittent because the ...

The effect of silicon supplementation and drought stress on the deposition of callose and chemical components in the cell walls of the Brassica napus roots

BMC Plant Biology
Background Silicon has an important role in regulating water management in plants. It is deposited in cell walls and creates a mechanical barrier against external factors.

ZmCals12 impacts maize growth and development by regulating symplastic transport

Journal of Integrative Agriculture
Carbohydrate partitioning from source to sink tissues is essential for plant growth and development. However, in maize (Zea mays L.), the molecular mechanisms by which callose synthase genes regulate this process remain largely unexplored.

Unlocking Precision in Callose Staining: Unveiling the Role of Sirofluor

Molecular Plant-Microbe Interactions
Callose is a vital component in plant biology, contributing to essential processes like pollen maturation and defense against pathogens. However, misconceptions surrounding callose staining persist, particularly regarding the role of aniline blue.
