摘要 皮刺可对抗食草动物、病原体或机械损伤,同时还可防止水分流失。然而,皮刺是否具有新功能以及皮刺模式的分子遗传学仍未得到充分探索。我们为无皮刺 品种BT生成了一个高质量的参考基因组组装,以识别与茎皮刺发育相关的遗传调控元件。BT 基因组本身以及玫瑰驯化中的创始基因型品种‘Old Blush’ (R. chinensis) 具有高水平的序列多样性。确定了茎皮刺密度的遗传,并鉴定了两个 QTL。QTL 中差异表达的基因与水相关功能有关,这表明皮刺密度可能与对潮湿环境的适应有关。虽然皮刺相关的基因调控网络 (GRN) 高度保守,但关键候选基因的表达变异与皮刺密度有关。我们的研究为蔷薇科植物的基因组进化提供了基础资源和见解。持续努力确定玫瑰关键性状的分子基础可能会改善园艺市场。
摘要(英) Prickles act against herbivores, pathogens or mechanical injury, while also preventing water loss. However, whether prickles have new function and the molecular genetics of prickle patterning remain poorly explored. Here, we generated a high-quality reference genome assembly for ‘Basye’s Thornless’ (BT), a prickle-free cultivar of Rosa wichuraiana, to identify genetic elements related to stem prickle development. The BT genome harbors a high level of sequence diversity in itself and with cultivar ‘Old Blush’ (R. chinensis), a founder genotype in rose domestication. Inheritance of stem prickle density was determined and two QTL were identified. Differentially expressed genes in QTL were involved in water-related functions, suggesting that prickle density may hitchhike with adaptations to moist environments. While the prickle-related gene-regulatory-network (GRN) was highly conserved, the expression variation of key candidate genes was associated with prickle density. Our study provides fundamental resources and insights for genome evolution in the Rosaceae. Ongoing efforts on identification of the molecular bases for key rose traits may lead to improvements for horticultural markets.
