温度调节是提高苹果果实采后品质，特别是防止冷害的有效途径。人们对改变苹果果实品质的变暖机制的分子机制知之甚少，也不清楚变暖如何有助于避免表皮疾病的发展。在这里，我们报告的转录反应的“史密斯奶奶”果皮在长期冷藏的早期阶段，间歇性升温，表面上有机兼容的策略，有效地降低了发病率。我们观察到两个时间上不同的基因表达，这是发现的共表达网络分析。一个配置文件在很大程度上是一致的恢复从低温胁迫，而另一个揭示了短暂的转变标记的激素信号和转录和翻译机制。总而言之，我们的分析指出新的方面的浅表性皮炎病因学和外切的候选基因，可能是有用的发现分子过程，促进，以及减轻，果皮疾病的列表。
Temperature conditioning is an effective approach for enhancing some aspects of postharvest apple fruit quality, particularly avoidance of chilling injury. The molecular mechanisms of warming regimes that alter apple fruit quality are poorly understood, as is how warming contributes to avoiding development of the peel disorder superficial scald. Here we report transcriptional responses of 'Granny Smith' fruit peel during the early phases of long-term cold storage in response to intermittent warming, an ostensibly organic compliant strategy that effectively reduced scald incidence. We observed two temporally distinct classes of gene expression, which were discovered by co-expression network analyses. One profile is largely concordant with recovery from chilling stress, whereas the other reveals transient shifts marked by hormone signaling and transcription and translation machinery. Altogether, our analyses point to novel aspects of superficial scald etiology and circumscribes a list of candidate genes that may be useful to uncover molecular processes that promote, as well as mitigate, the peel disorder.
