倒伏仍然是甘蓝型油菜等重要作物品种产量损失的主要原因。因此，了解抗倒伏的遗传调控对世界各地的育种者来说是非常重要的。目前旨在将倒伏风险降至最低的策略包括整合矮化基因或应用植物生长调节剂。然而，尽管作出了这些努力，住宿仍然是一个持续存在的问题，因此，实施新颖的、相辅相成的住宿控制战略是非常令人感兴趣的。一种方法是专注于了解树干机械强度背后的遗传特性。考虑到这一点，我们筛选了甘蓝型油菜遗传多样性训练小组，以研究甘蓝型油菜茎机械强度和相关性状的变异。利用联合转录学，我们确定了一系列有价值的性状的分子标记。使用一个独立的遗传多样性测试小组，我们证明了所采用的方法在识别预测标记方面是稳健的。此外，基于与拟南芥的保守同源性，我们能够为检测到的标记关联提供生物学背景，并为果胶甲基酯化在十字花科植物茎机械强度中的作用提供证据。本文的在线版本(10.1007/s11032-0180781-6)包含补充材料，可供授权用户使用。
Lodging continues to be a major cause of yield loss in important crop species such as Brassica napus. Understanding the genetic regulation of lodging resistance is therefore of key interest to breeders worldwide. Current strategies aimed at minimising lodging risk involve the incorporation of dwarfing genes or the application of plant growth regulators. However, despite these efforts, lodging continues to be a persistent problem and it is therefore of high interest that novel, complimentary strategies for lodging control are implemented. One approach would be to focus on understanding the genetic properties underlying stem mechanical strength. With this in mind, we screened a training genetic diversity panel of B. napus accession for variation in stem mechanical strength and related traits. Using Associative Transcriptomics, we identified molecular markers for a suite of valuable traits. Using an independent test genetic diversity panel, we show that the methods employed are robust for identification of predictive markers. Furthermore, based on conserved synteny with Arabidopsis thaliana, we are able to provide a biological context to the marker associations detected and provide evidence for a role in pectin methylesterification in contributing to stem mechanical strength in Brassicaceae.
