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 (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 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 Oil content and fatty acid composition were investigated on 12 castor varieties and strains by using the soxhlet extraction method and capillary gas chromatography. This was made to provide a reference and theoretical basis for castorbean breeding with high oil content, determine variability of seed compounds for breeding purposes, and broaden chemical material choices. Results revealed that crude fat percentage in seeds ranged from 18.91 to 35.84% with an average of 25.91%; the absolute content of ricinoleic acid varied between 171.65 g/kg and 314.03 g/kg with an average of 222.43 g/kg, and kernel crude fat… More >
