OsASA2 Loss-of-Function Confers Broad-Spectrum Disease Resistance and Triggers Cell Death by Regulating Anthranilate Synthase Activity in Rice. [PDF]
Loss of OsASA2 disrupts anthranilate synthase regulation, triggering metabolic reprogramming, cell death and broad‐spectrum disease resistance in rice. ABSTRACT Lesion mimic mutants are valuable for studying plant cell death and defence mechanisms.

Molecular diversity of citrus genotypes using callose synthase 7 gene markers linked to Huanglongbing resistance [PDF]
Huanglongbing (HLB), caused by Candidatus Liberibacter asiaticus, is a notable disease affecting citrus plantations globally. Several studies showed that the callose synthase 7 gene is crucial for the citrus defense system against this pathogen.

The molecular architecture of the Arabidopsis callose synthase complex
Callose synthase is responsible for the targeted deposition of the β-1,3-glucan polymer, callose which underlines essential plant developmental processes, including cell division, pathogen defense or cell-cell communication.

Evolutionary history of callose synthases in terrestrial plants with emphasis on proteins involved in male gametophyte development. [PDF]
Callose is a plant-specific polysaccharide (β-1,3-glucan) playing an important role in angiosperms in many developmental processes and responses to biotic and abiotic stresses.

Callose is a plant cell wall polysaccharide whose deposition is spatiotemporally regulated in various developmental processes and environmental stress responses. The appearance of callose in premeiotic anthers is a prominent histological hallmark for the

Role of callose accumulation in the suppression of calcium-deficiency-induced necrosis in Arabidopsis thaliana cotyledons [PDF]
Calcium (Ca) deficiency symptoms, such as blossom end rot in tomato and tip burn in lettuce, are among the most serious physiological disorders in agriculture. A common feature of this disorder is the expansion of necrosis. However, mechanisms underlying

Exocyst Subunit EXO70H4 Has a Specific Role in Callose Synthase Secretion and Silica Accumulation1[OPEN] [PDF]
Exocyst subunit EXO70H4 localizes to the apical subdomain of the trichome. Here, it is responsible for callose synthase secretion; callose is essential for cell wall silicification.

Decoding MAPK cascades in plant immunity: Activation, regulation, integration, and pathogen manipulation. [PDF]
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.
