    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 >

    Functional Studies of Castor (Ricinus communis L.) PLC Family Genes in Arabidopsis Inflorescence Development

    Yanpeng Wen1,#, Rui Luo1,#, Lili Li1, Xiaotian Liang1, Xuemei Hu1, Ruxin Li1, Zhiyan Wang1, Fenglan Huang1,2,3,4,5,*

    Phyton-International Journal of Experimental Botany, Vol.92, No.11, pp. 3091-3112, 2023, DOI:10.32604/phyton.2023.030960

    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 PLCMore >
