Botrytis cinerea, a widespread plant pathogen with a necrotrophic lifestyle, causes gray mold disease in many crops. Massive secretion of enzymes and toxins was long considered to be the main driver of infection, but recent studies have uncovered a rich toolbox for B. cinerea pathogenicity. The emerging picture is of a multilayered infection process governed by the exchange of factors that collectively contribute to disease development. No plant shows complete resistance against B. cinerea, but pattern-triggered plant immune responses have the potential to significantly reduce disease progression, opening new possibilities for producing B. cinerea-tolerant plants. We examine current B. cinerea infection models, highlight knowledge gaps, and suggest directions for future studies.
灰葡萄孢是一种广泛存在的具有坏死营养型生活方式的植物病原体，可在许多作物上引发灰霉病。长期以来，大量酶和毒素的分泌被认为是感染的主要驱动因素，但最近的研究发现了灰葡萄孢致病性的丰富“工具包”。新出现的情况是，感染过程是多层次的，由共同促进疾病发展的因子交换所控制。没有植物对灰葡萄孢表现出完全抗性，但模式触发的植物免疫反应有可能显著降低疾病进展，为培育耐灰葡萄孢的植物开辟了新的可能性。我们研究了当前的灰葡萄孢感染模型，突出了知识空白，并提出了未来研究的方向。
