Calcium signaling in plant defense

New Plant Protection, EarlyView.
Calcium signaling acts as a central hub in plant immunity, translating pathogen perception into defense responses. This review highlights the channels, sensors, and signaling networks involved, and discusses how pathogens subvert calcium dynamics, as well as how this knowledge may inspire innovative strategies for engineering durable crop resistance ...

An efficient method for the extraction and the quantitative determination of callose from HLB-affected and healthy citrus

Frontiers in Agronomy
Callose is a 1,3-β glucan responsible for several processes in planta such as cell division, ripening of pollen mother cells, maintaining the plasmodesmata opening, and providing structure to the sieve plates.

Callose formation in injured cells of the vegetative and generative thallus of Chara vulgaris L. Absence of callose in the process of cytodifferentiation

Acta Societatis Botanicorum Poloniae, 2014
In an alga Chara vulgaris L. the processes of differentiation of vegetative system cells of the thallus, and initiation and development of generative organs are not associated with callose formation.

A Phytophthora effector protein promotes symplastic cell-to-cell trafficking by physical interaction with plasmodesmata-localized callose synthases.

New Phytologist, 2020
Pathogen effectors act as disease promoting factors that target specific host proteins with roles in plant immunity. Here, we investigate the function of the RxLR3 effector of the plant pathogen Phytophthora brassicae.

Plasmodesmata‐located proteins: The molecular hubs in noncell‐autonomous immunity

New Plant Protection, EarlyView.
Plasmodesmata serve as critical battlefields for plant immunity, regulated by diverse proteins. This article provides a comprehensive review of the regulatory mechanisms, challenges, and future directions concerning proteins located within plasmodesmata and their roles in plant defense responses.

The pollen receptor kinase LePRK2 mediates growth-promoting signals and positively regulates pollen germination and tube growth [PDF]

, 2008
In flowering plants, the process of pollen germination and tube growth is required for successful fertilization. A pollen receptor kinase from tomato (Solanum lycopersicum), LePRK2, has been implicated in signaling during pollen germination and tube ...

First genome sequence of a European Alternaria brassicae isolate and genes involved in early development of alternaria leaf spot on Brassica juncea

Pest Management Science, EarlyView.
This article reports the first genome sequence of a UK Alternaria brassicae isolate. Dual RNA‐sequencing profiling of A. brassicae‐infected Brassica juncea leaves identified differentially expressed genes involved in pathogenicity and host response pathways in moderately resistant Sej‐2 (2) and moderately susceptible Pusa Jaikisan cultivars.

The plasmodesmal protein PDLP1 localises to haustoria-associated membranes during downy mildew infection and regulates callose deposition.

PLoS Pathogens, 2014
The downy mildew pathogen Hyaloperonospora arabidopsidis (Hpa) is a filamentous oomycete that invades plant cells via sophisticated but poorly understood structures called haustoria.

T-loop phosphorylation of Arabidopsis CDKA;1 is required for its function and can be partially substituted by an aspartate residue [PDF]

, 2007
As in other eukaryotes, progression through the cell cycle in plants is governed by cyclin-dependent kinases. Phosphorylation of a canonical Thr residue in the T-loop of the kinases is required for high enzyme activity in animals and yeast.
