Abstract

Calochortus tolmiei Hook. & Arn., a bulbous monocot with cat's ear flowers in the angiosperm family Liliaceae, is a perennial herb native to northern California, Oregon, and Washington. Calochortus exhibits substantial morphological and karyotype diversity with multiple floral forms and a haploid chromosome number varying from six to 10. Here, we present the first high-quality reference assembly in Liliaceae for C. tolmiei, with a scaffolded assembly of 2.9 Gbp with a N50 of 296 Mbp. Notably, 92% of the assembled genome is scaffolded into 10 pseudomolecules, matching the documented chromosome count of C. tolmiei. The genome contains 31,049 protein-coding genes, with 86.2% being functionally annotated. The closest reference-quality genome assembly to C. tolmiei is from Chionographis japonica (Willd.) Maxim. (Melianthiaceae), which diverged approximately 83 MYA, providing a valuable genomic resource in the Liliales, an order which lacks genomic resources.

托氏蛤蛤的参考基因组。和攻击。（百合科），一种猫耳百合。

Calochortus tolmiei Hook。和攻击。百合科被子植物中一种有猫耳花的球茎单子叶植物，是一种多年生草本植物，原产于加利福尼亚北部、俄勒冈州和华盛顿州。Calochortus具有丰富的形态和核型多样性，具有多种花形态和单倍体染色体数，从6到10不等。本研究获得了百合科中第一个高质量的托尔米伊（C. tolmiei）参考序列，该序列为2.9 Gbp， N50为296 Mbp。值得注意的是，92%的组装基因组被支架成10个假分子，与记录的tolmiei染色体计数相匹配。基因组包含31,049个蛋白质编码基因，其中86.2%被功能注释。与tolmiei最接近的参考质量基因组组合来自Chionographis japonica （Willd.）。的格言。（Melianthiaceae），为百合科这一缺乏基因组资源的目提供了宝贵的基因组资源。

期刊介绍： G3: Genes, Genomes, Genetics provides a forum for the publication of high‐quality foundational research, particularly research that generates useful genetic and genomic information such as genome maps, single gene studies, genome‐wide association and QTL studies, as well as genome reports, mutant screens, and advances in methods and technology. The Editorial Board of G3 believes that rapid dissemination of these data is the necessary foundation for analysis that leads to mechanistic insights. G3, published by the Genetics Society of America, meets the critical and growing need of the genetics community for rapid review and publication of important results in all areas of genetics. G3 offers the opportunity to publish the puzzling finding or to present unpublished results that may not have been submitted for review and publication due to a perceived lack of a potential high-impact finding. G3 has earned the DOAJ Seal, which is a mark of certification for open access journals, awarded by DOAJ to journals that achieve a high level of openness, adhere to Best Practice and high publishing standards.
