Developmental Regulation of the (1,3)-β-Glucan (Callose) Synthase from Tomato [PDF]

Plant Physiology, 1991
Activity levels of UDP-glucose: (1,3)-beta-glucan (callose) synthase in microsomal membranes of pericarp tissue from tomato fruit (Lycoperisicon esculentum Mill, cv Rutgers) were determined during development and ripening. Addition of the phospholipase inhibitors O-phosphorylcholine and glycerol-1-phosphate to homogenization buffers was necessary to ...

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.

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.

Two salivary proteins Sm10 and SmC002 from grain aphid Sitobion miscanthi modulate wheat defense and enhance aphid performance

Frontiers in Plant Science, 2023
The grain aphid Sitobion miscanthi is a serious pest of wheat that causes severe economic damage by sucking phloem sap and transmitting plant viruses. Here, two putative salivary effector homologs from S.

14‐3‐3 proteins: Central hubs in plant development and stress adaptation

Journal of Integrative Plant Biology, Volume 68, Issue 8, Page 3107-3132, August 2026.
This review highlights recent advances elucidating the important roles of 14‐3‐3 proteins in regulating phytohormone networks, biotic and abiotic stress tolerance, growth‐defense trade‐offs, and evolutionary adaptations. Furthermore, it provides a forward‐looking perspective on 14‐3‐3 biology and the development of climate‐resilient smart crops under ...

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.

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.

Synergistic Activation of Defense Responses in Arabidopsis by Simultaneous Loss of the GSL5 Callose Synthase and the EDR1 Protein Kinase

Molecular Plant-Microbe Interactions, 2010
Loss-of-function mutations in the EDR1 gene of Arabidopsis confer enhanced resistance to Golovinomyces cichoracearum (powdery mildew). Disease resistance mediated by the edr1 mutation is dependent on an intact salicylic acid (SA) signaling pathway, but ...

Plant G proteins: Versatile signaling hubs for synergistic improvement of agronomic traits

Journal of Integrative Plant Biology, Volume 68, Issue 8, Page 3133-3152, August 2026.
This review highlights the roles of G‐protein signaling in crop yield and quality, as well as abiotic and biotic stress responses. It also discusses the feasibility of breaking the trade‐off between plant growth and stress tolerance via dissecting G‐protein regulatory pathways, gene editing, mining natural elite variants, and AI‐assisted breeding ...

Fungal F8-Culture Filtrate Induces Tomato Resistance against Tomato Yellow Leaf Curl Thailand Virus

Viruses, 2021
Tomato (Solanum lycopersicum) is an important economic crop worldwide. However, tomato production is jeopardized by the devastating tomato yellow leaf curl disease caused by whitefly-transmitted begomoviruses (WTBs).
