Abstract

Brassica rapa displays a wide range of morphological diversity which is exploited for a variety of food crops. Here we present a high-quality genome assembly for pak choi (Brassica rapa L. subsp. chinensis), an important non-heading leafy vegetable, and comparison with the genomes of heading type Chinese cabbage and the oilseed form, yellow sarson. Gene presence-absence variation (PAV) and genomic structural variations (SV) were identified, together with single nucleotide polymorphisms (SNPs). The structure and expression of genes for leaf morphology and flowering were compared between the three morphotypes revealing candidate genes for these traits in B. rapa. The pak choi genome assembly and its comparison with other B. rapa genome assemblies provides a valuable resource for the genetic improvement of this important vegetable crop and as a model to understand the diversity of morphological variation across Brassica species.

摘要

白菜型油菜表现出广泛的形态多样性，被广泛用于各种食用作物。在这里，我们为一种重要的非结球叶菜——白菜（Brassica rapa L. subsp. chinensis）提供了一个高质量的基因组组装，并与结球甘蓝和油菜的基因组进行了比较。鉴定了基因存在缺失变异（PAV）和基因组结构变异（SV），以及单核苷酸多态性（SNP）。比较了这三种形态的叶片形态和开花相关基因的结构和表达，揭示了白菜型油菜中这些性状的候选基因。白菜型油菜基因组组装及其与其他白菜型油菜基因组组装的比较为这种重要蔬菜作物的遗传改良提供了有价值的资源，并为理解芸薹属物种形态变异多样性提供了模型。
