Abstract The yield of castor is influenced by the type of inflorescence and the proportion of female flowers. However, there are few studies on the genetic mechanism involved in the development and differentiation of castor inflorescences. In this study, we performed transcriptomic analyses of three different phenotypes of inflorescences at the five-leaf stage. In comparison to the MI (complete pistil without willow leaves), 290 and 89 differentially expressed genes (DEGs) were found in the SFI (complete pistil with willow leaves) and the BI (monoecious inflorescence), respectively. Among the DEGs, 104 and 88 were upregulated in the… More >

Abstract Castor is one of the top 10 oil crops in the world and has extremely valuable uses. Castor inflorescences directly affect yield, so the study of inflorescence development is very important in increasing castor yield. Our previous studies have shown that the PIP5K gene family (PIP5Ks) is associated with inflorescence development. In this study, to determine the function of each PIP5K gene in castor, a female Lm-type castor line, aLmAB2, was used to determine the relative expression levels of the PIP5Ks in castor inflorescences. Six PIP5K genes were heterologously overexpressed in Arabidopsis thaliana, the relative expression of each gene… More >

Abstract Castor, scientifically known as Ricinus communis L., is among the top ten oil crops globally. It is considered a renewable resource and is commonly referred to as ‘green oil’. Castor seeds contain castor oil as their main component, which is predominantly composed of ricinoleic acid. This study utilized RNAi technology to silence the NPC6 gene in NO.2129 castor, resulting in the creation of mutant plants L1 and L2. The weight of 100 dry seed kernels from L1 and L2 exceeds that from NO.2129. The crude fat and ricinoleic acid levels of L1 and L2 were higher than… More >

Abstract Castor (Ricinus communis L.) is one of the top 10 oil crops in the world, and inflorescence is a trait that directly affects its yield. Phospholipase C (PLCs) is involved in many plant activities and metabolic processes. To study the functions of PLC family genes in the regulation of the inflorescence development of the female line of Lm-type castor aLmAB2, we determined the expression levels of six PLC family genes of three types of inflorescences of aLmAB2 (isofemale line, female line, bisexual line) at different developmental stages. The results showed that the 6 genes of the castor PLC… More >

Abstract Castor bean (Ricinus communis L.), is one of the top 10 oilseed crops in the world and, therefore, of high economic value. Hybridization is one of the most effective ways to breed new varieties with high yield, high oil content, and better stress resistance. Therefore, prediction of desired traits in castor hybrid offspring is particularly important. In this study, proteomic analysis was performed to identify differentially expressed proteins (DEPs) in seeds between castor hybrid offspring and their female (Lm female line aLmAB₂) and male parents (CSR·181). Among the DEPs upregulated in the seeds of hybrid offspring, the… More >

Abstract Castor (Ricinus communis L.) is one of ten oil crops in the world and has complex inflorescence styles. Generally, castor has three inflorescence types: single female inflorescence (SiFF), standard female inflorescence (StFF) and bisexual inflorescence (BF). StFF is realized as a restorer line and as a maintainer line, which was applied to castor hybrid breeding. However, the developmental mechanism of the three inflorescences is not clear. Therefore, we used proteomic techniques to analyze different inflorescence styles. A total of 72 diferentially abundant protein species (DAPs) were detected. These DAPs are primarily involved in carbon and energy More >

Abstract Nowadays, waterborne polyurethanes (WPUs) prepared from renewable resources has attracted more and more attention. However, due to its structure, the prepared films easily swells in water and greatly affects the application range of WPUs. Therefore, solving the problem of water resistance is a way to improve the application range of WPUs. In this study, a series of WPU dispersions were prepared using castor oil as the bio-based polyol. Besides, the thiol-ene photo click reaction was carried out on the WPU films for silane modification. The effect of the silane modification on the chemical structures of… More > Graphic Abstract

Abstract In order to provide a molecular basis for selecting good hybrid combinations for the identification of castor bean germplasm resources, fingerprint and genetic diversity analysis of 52 castor bean materials from 12 regions in 5 countries were constructed by using the Functinal Markers (FMs) associated with fatty acid metabolism-related genes. A total of 72 alleles were amplified by 29 pairs of FMs with an average of 2.483 per marker and the polymorphic information content was 0.103–0.695. Shannon’s information index (I), observed heterozygosity (Ho) and expected heterozygosity (He) were 0.699, 0.188 and 0.436 respectively. The clustering More >

Abstract Increased urbanization and industrialization have greatly contributed to the emission of higher amount of heavy metals such as cadmium, nickel, and lead into the environment. These metals are non-biodegradable and toxic, causing much effects on plants and by extension to animals and humans, which have become a major global concern. The inherent ability of plants to resist heavy metal toxicity seems to be the most sustainable and cost-effective strategy. Castor plant is widely studied due to its tolerance to the effects of heavy metal contaminated soils, owing to its large biomass content and high accumulating… More >

Abstract An acidic cation exchange resin has been used to prepare epoxidised castor oil (ECO) which was used as a co-plasticizer with epoxidised soyabean oil (ESBO) for processing polyvinyl chloride (PVC). The structure of ECO was confirmed and its physico chemical properties were evaluated. PVC/ (ESBO&ECO) blends were prepared by melt mixing and compression molded into sheets. The specimens were evaluated for tensile properties, impact strength and hardness. While the tensile strength did not vary much, the elongation reduced with the replacement of ESBO with ECO. Dynamic mechanical studies revealed that the glass transition temperature increased More >
