Comparative transcriptomics link candidate genes to double flowers in Clivia miniata
Comparative transcriptomics of single-, semi-double- and double-flowered Clivia miniata identified candidate genes associated with stamen petaloidy but did not establish causality. A comparative transcriptome study of the ornamental plant Clivia miniata has identified candidate genes and regulatory pathways associated with stamen petaloidy and double-flower formation Researchers sequenced flower buds and tepals from single-, semi-double- and double-flowered plants, assembling 127,524 unigenes for analysis The study, published in BMC Plant Biology, links changes in gene expression to metabolism, phytohormone signaling and floral identity, while providing a candidate framework for further investigation rather than establishing a causal mechanism The researchers compared gene expression across the three floral phenotypes and identified 44,140 differentially expressed genes in flower-bud…
