辣椒（Capsicum annuum）是世界上消费量最大的蔬菜作物之一，因其具有多种营养和药用价值而对人类有益。辣椒基因组资源是公开的，辣椒基因组已经完成，转录组等大量数据已经积累。然而，需要全球转录组分析来确定辣椒农艺性状相关的分子机制，但有限的分析已发表。本文报道了辣椒果实成熟和病原菌侵染过程中转录组的综合分析。在成熟过程中，从胎盘和果皮的7个发育阶段获得转录组数据。为了揭示感染过程中的全球转录组景观，研究了三种病原菌（疫霉菌、辣椒斑纹病毒和烟草花叶病毒P0株）感染后6个时间点的叶片。本研究的大量平行转录组分析将为辣椒果实发育和抗病的分子网络检测提供有价值的资源。
Hot pepper (Capsicum annuum) is one of the most consumed vegetable crops in the world and useful to human as it has many nutritional and medicinal values. Genomic resources of pepper are publically available since the pepper genomes have been completed and massive data such as transcriptomes have been deposited. Nevertheless, global transcriptome profiling is needed to identify molecular mechanisms related to agronomic traits in pepper, but limited analyses are published. Here, we report the comprehensive analysis of pepper transcriptomes during fruit ripening and pathogen infection. For the ripening, transcriptome data were obtained from placenta and pericarp at seven developmental stages. To reveal global transcriptomic landscapes during infection, leaves at six time points post- infection by one of three pathogens (Phytophthora infestans, Pepper mottle virus, and Tobacco mosaic virus P0 strain) were profiled. The massive parallel transcriptome profiling in this study will serve as a valuable resource for detection of molecular networks of fruit development and disease resistance in Capsicum annuum.
