The effect of intracellular calcium level regulators on the synthesis of pollen tube callose in Oenothera biennis L.

Acta Societatis Botanicorum Poloniae, 2014
It is shown that callose synthesis in the Oenothera biennis pollen tube is regulated by the endogenous Ca2+ level. Calcium antagonists reduced the amount of callose in the wall above the tip of the pollen tube (Verapamil - calcium channels blocker) and ...

Squash silverleaf disorder and whitefly (Bemisia tabaci MEAM1) infestation: Implications for plant disease management in a changing climate

Annals of Applied Biology, Volume 189, Issue 2, September 2026.
Squash Silverleaf Disorder (SLD) is growing in its economic impact due to the invasive behaviour of the silverleaf whitefly (Bemisia tabaci MEAM1). In this review we summarize what is currently known about the whitefly‐squash interaction, how both the disease and the whitefly are being affected by climate change, and discuss current and novel ...

ABA Is Required for Leptosphaeria maculans Resistance via ABI1- and ABI4-Dependent Signaling

Molecular Plant-Microbe Interactions, 2007
Abscisic acid (ABA) is a defense hormone with influence on callose-dependent and -independent resistance against Leptosphaeria maculans acting in the RLM1Col pathway.

A tomato MIK2‐clade receptor is involved in the perception of a Fusarium‐derived elicitor

New Phytologist, Volume 251, Issue 5, Page 2777-2798, September 2026.
Fusarium elicitor responsivness and MIK2‐clade proteins are conserved across plant families. Summary Plants continuously monitor their environment to adapt to threats affecting health and fitness. Cell‐surface receptors detect conserved microbe‐associated molecular patterns (MAMPs) or endogenous immunogenic signals to activate signaling pathways that ...

Cytological and Molecular Characteristics of Pollen Abortion in Lily with Dysplastic Tapetum

Horticultural Plant Journal, 2019
Lily was grown worldwide as a fresh cutting flower because of its colorful petals, but its anther contained a large number of pollen grains that cause serious pollen contamination, however, pollen abortion can effectively reduce the level of pollen ...

The regulatory frameworks surrounding CRISPR‐edited papaya and their impact on international commerce

Journal of the Science of Food and Agriculture, Volume 106, Issue 11, Page 6262-6270, 30 August 2026.
Abstract The papaya tree (Carica papaya L.), native to the Americas, is cultivated in tropical regions and holds substantial economic importance, with an estimated export volume of 365 000 t in 2023. However, diseases caused by viruses, fungi, bacteria, and nematodes can lead to severe losses.

Higher Temperature and Host Age Alter Infection Outcomes in a Multi‐Pathogen System

Ecology and Evolution, Volume 16, Issue 8, August 2026.
Warming, host age, and pathogen identity shaped disease outcomes more strongly than co‐infection in a factorial experiment with two fungal pathogens on tall fescue. Higher temperatures generally reduced disease severity, while host age modified responses‐older plants were more resistant in some contexts, but this depended on temperature and pathogen ...

Genomic Identification of Callose Synthase (CalS) Gene Family in Sorghum (Sorghum bicolor) and Comparative In Silico Expression Analysis under Aphid (Melanaphis sacchari) Infestation

Agronomy
Callose is widely present in higher plants and plays a significant role in plant growth, development, and response to various stresses. Although numerous studies have highlighted the importance of the callose synthase (CalS) genes, their role in the ...

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.

Strigolactone‐mediated architecture regulation and stress resilience: Insights and innovations for crop breeding

Journal of Integrative Plant Biology, Volume 68, Issue 8, Page 2548-2576, August 2026.
This review summarizes the discovery, biosynthesis, and transport of strigolactone, and the D14‐D3/MAX2‐D53/SMXLs signaling module. It highlights diverse roles of strigolactone in plant architecture, stress responses, and crop breeding, including species‐specific functions, hormonal crosstalk, and agricultural applications.
