细胞壁对植物生长和发育至关重要，提供支持和保护免受外部环境的影响。胼胝质是一种葡聚糖，其在包括称为胞间连丝的细胞间孔周围的专门细胞壁微区中积累。尽管胼胝质在细胞壁中占很小的比例（在模式植物拟南芥中约为0.3%），但胼胝质的积累调节重要的生物过程，如韧皮部和花粉发育，细胞分裂，器官形成，对病原体入侵的反应以及土壤中营养物质和有毒金属的变化。胼胝质的积累改变细胞壁的性质，并限制胞间连丝的孔径，影响信号蛋白和RNA分子的运输，调节植物发育和环境反应。虽然胼胝质在胞间连丝细胞壁内外的重要性已被广泛认识，但控制其合成和降解变化的潜在机制仍然没有得到解决。在这篇综述中，我们探讨了最新的文献解决胼胝质代谢的影响胼胝质积累的分子因素，在互惠共生体和致病诱导剂的重点。我们讨论了信号通路中的共性，确定研究差距，并强调了在改善植物对有益微生物和病原微生物的反应中靶向胼胝质的机会。在这篇综述中，我们暴露了我们目前的理解的机制，调节胼胝质积累的微生物。其目的是确定研究差距，并突出机会，以目标胼胝质在改善植物对有益微生物和病原微生物的反应。缺少控制胼胝质代谢酶的表达和活性的信号通路和相互作用及其对微生物共生体响应的相对贡献的信息。知识也缺乏进化和物理力学特征，选择胼胝质在这个过程中发挥作用。我们还强调了使用非致病性和互惠微生物引发胼胝质产生更强植物防御的机会。
Cell walls are essential for plant growth and development, providing support and protection from external environments. Callose is a glucan that accumulates in specialized cell wall microdomains including around intercellular pores called plasmodesmata. Despite representing a small percentage of the cell wall (~0.3% in the model plant Arabidopsis thaliana), callose accumulation regulates important biological processes such as phloem and pollen development, cell division, organ formation, responses to pathogenic invasion and to changes in nutrients and toxic metals in the soil. Callose accumulation modifies cell wall properties and restricts plasmodesmata aperture, affecting the transport of signaling proteins and RNA molecules that regulate plant developmental and environmental responses. Although the importance of callose, at and outside plasmodesmata cell walls, is widely recognized, the underlying mechanisms controlling changes in its synthesis and degradation are still unresolved. In this review, we explore the most recent literature addressing callose metabolism with a focus on the molecular factors affecting callose accumulation in response to mutualistic symbionts and pathogenic elicitors. We discuss commonalities in the signaling pathways, identify research gaps and highlight opportunities to target callose in the improvement of plant responses to beneficial versus pathogenic microbes. In this review, we expose our current understanding of the mechanisms that regulate callose accumulation in response to microbes. The aim is to identify research gaps and highlight opportunities to target callose in the improvement of plant responses to beneficial versus pathogenic microbes. Information was missing on the signaling pathways and interactions controlling the expression and activity of callose metabolic enzymes and their relative contribution to the response to microbial symbionts. Knowledge also lacks on the evolutionary and physicomechanical features that selected callose to function in this process. We also highlight opportunities for stronger plant defenses that emerge from priming callose using non‐pathogenic and mutualistic microbes.
