Transcriptome profile of pecan scab resistant and susceptible trees from a pecan provenance collection

Transcriptomes for pecan trees (Carya illinoinensis) that were consistently resistant and susceptible to wild populations of Venturia effusa across three years of data collection where quantified using RNAseq. Venturia effusa is the causative agent of the most yield limiting disease for pecan in humid regions. The transcriptomes of infected susceptible plants were also quantified. Evaluation of data generated for this work will help identify genes and biological pathways responsible for susceptibility/resistance to the pathogen. This information will help lead future breeding programs and give biotechnological options for durable resistance to pecan scab.

连续三年数据收集期间，通过RNA测序技术对山核桃树（Carya illinoinensis）的转录组进行了量化分析，这些山核桃树对Venturia effusa野生种群表现出持续的抗性和易感性。Venturia effusa是潮湿地区山核桃产量限制性最强的病原体。同时，对感染易感植物的转录组也进行了量化。对本次工作中生成数据的评估将有助于识别导致对病原体易感/抗性的基因和生物学通路。这些信息将有助于指导未来的育种计划，并为山核桃溃疡病的持久抗性提供生物技术选择。
