Cacao pod response to Phytophthora palmivora inoculation

The oomycete Phytophthora palmivora infects the fruit of cacao trees (Theobroma cacao) causing black pod rot and reducing yields. Cacao genotypes vary in their resistance levels to P. palmivora, yet our understanding of how cacao fruit respond to the pathogen at the molecular level during disease establishment is limited. To address this issue, a disease development and RNA-Seq study was conducted on pods of seven cacao genotypes to better understand their reactions to the post-penetration stage of P. palmivora infection.

卵菌纲真菌Phytophthora palmivora感染可可树（Theobroma cacao）果实，导致黑腐病并降低产量。可可基因型在对抗P. palmivora的抗性水平上存在差异，然而，我们对可可果实如何在分子层面应对病原体在病害建立过程中的侵入阶段的理解尚显不足。为解决这一问题，对七个可可基因型的果蒂进行了病害发展和RNA-Seq研究，以期更深入地了解它们对P. palmivora侵入后阶段的反应。
