Callose balancing at plasmodesmata.

Journal of Experimental Botany, 2018
In plants, communication and molecular exchanges between different cells and tissues are dependent on the apoplastic and symplastic pathways. Symplastic molecular exchanges take place through the plasmodesmata, which connect the cytoplasm of neighboring ...

Sphingolipids Modulate Secretion of Glycosylphosphatidylinositol-Anchored Plasmodesmata Proteins and Callose Deposition1

Plant Physiology, 2020
Arabidopsis glucosyl sphingolipid-modulated plasmodesmal gating involves modulation of the glycosylphosphatidylinositol-anchored PdBG2 protein secretion machinery and a change in callose accumulation.

Current Trends, Future Prospects and Constraints of Whole Microalgae and Their Fractions as a Functional Feed Ingredient for Animals

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Microalgae are a highly diverse group of unicellular organisms that grow in a wide range of aquatic environments and are widely used as dietary supplements for both human and animal applications. Microalgae are rich in lipids, proteins, carbohydrates and other valuable bioactive components such as pigments, antioxidants and vitamins.

ZmMS39 encodes a callose synthase essential for male fertility in maize (Zea mays L.)

Crop Journal, 2023
Callose contributes to many biological processes of higher plants including pollen development, cell plate and vascular tissue formation, as well as regulating the transport function of plasmodesmata. The functions of callose synthase genes in maize have

Stronger induction of callose deposition in barley by Russian wheat aphid than bird cherry-oat aphid is not associated with differences in callose synthase or ≤-1,3-glucanase expression [PDF]

, 2009
The effects of infestation by the bird cherry-oat aphid (BCA), (Rhopalosiphum padi L) and the Russian wheat aphid (RWA) (Diuraphis noxia Mordvilko) on callose deposition and gene expression related to callose accumulation were investigated in barley ...

Pollen-Specific Protein PSP231 Activates Callose Synthesis to Govern Male Gametogenesis and Pollen Germination1

Plant Physiology, 2020
A pollen-specific protein activates callose synthases by sequestering an RNA binding protein away from the mRNA encoding a transcriptional repressor, leading to the callose synthesis and deposition required for male gametogenesis and pollen germination ...

Quiescence of postharvest pathogens: a fungal inhibition process or an immune response of the unripe host fruit?

New Phytologist, EarlyView.
Summary Postharvest pathogens can infect fresh produce both before and after harvest, by direct or wound‐enhanced penetration, remaining quiescent until ripening. Biotrophic‐like postharvest pathogens persist beneath host cells and can remain in a state of quiescence.

Non-separated microspores 1 controls male meiotic callose deposition at the cell plate in rice

Crop Journal
In flowering plants, callose (β-1,3-glucan) plays a vital role in pollen development, especially in the separation and development of microspores. However, the molecular mechanism of callose deposition during rice pollen development remains unclear.

Callose deposition is essential for the completion of cytokinesis in the unicellular alga Penium margaritaceum

Journal of Cell Science, 2020
Cytokinesis in land plants involves the formation of a cell plate that develops into the new cell wall. Callose, a β-1,3 glucan, accumulates at later stages of cell plate development, presumably to stabilize this delicate membrane network during ...

Decoding plant defense signaling using the defenseless mutant

New Phytologist, EarlyView.
Summary Can plants live without defenses? Mutant analysis in Arabidopsis thaliana has identified numerous regulators of biotic, abiotic, and hormone‐based defenses, but the redundancy among separate defense pathways remains unexplored. We constructed an Arabidopsis mutant, defenseless, lacking six canonical defense pathways using abi1‐1 (abscisic acid),
