Morphology

Introduction

      Castor bean (Ricinus communis) is a perennial shrub of the Euphorbiaceae family with seeds containing 40-60% oil, and as a non-edible oil crop, it is an important industrial raw material for the production of lubricants and paints [1,2]. The seed oil of castor bean is a triacylglycerol composed of glycerol and different fatty acids [5], which has the advantages of low cloud point, low freezing point, and high cetane number, so it has a great economic impact and has been used in many fields such as agriculture, medicine, cosmetics, and toxicology [6]. In addition, castor bean has anti-swelling, laxative as well as anti-inflammatory effects, including potential antioxidant, antihistamine, anticancer, and hypotensive properties [5].
      In 2010, Chan et al. reported the draft genome sequence of Ricinus communis cv. Hela (4.6-fold coverage), which was the earliest information on the castor genome [6]. With the development of high-throughput sequencing technology, more accurate genomic information is beneficial for molecular breeding and genetic improvement of castor. In 2021, Kunming Institute of Botany and Southwest Forestry University assembled the chromosome-based genome of wild castor (Rc039) using PacBio Sequel third-generation sequencing and Hi-C technology [7]. Subsequently, the Shenzhen Agricultural Genome Research Institute and Hubei University College of Life Sciences released the chromosomal level assembly of WT05 in 2022 [8].
      Our database contains genomic information of castor cultivar Hela and wild Rc039.
