This study demonstrates that orange carrot was selected during the Renaissance period, probably in western Europe, through the selection of three recessive genes that increased the provitamin A carotenoid (α- and β-carotene) content.Category Archives: Nature Plants
The changing colour of carrot
Nature Plants, Published online: 28 September 2023; doi:10.1038/s41477-023-01523-9
By assembling a high-quality carrot reference genome and resequencing 630 accessions, a study by Coe et al. reveals the transformative journey of carrot from wild progenitor to modern cultivar and the concomitant accumulation of carotenoids in its taproot.Plantorganelle Hunter is an effective deep-learning-based method for plant organelle phenotyping in electron microscopy
Nature Plants, Published online: 25 September 2023; doi:10.1038/s41477-023-01527-5
A deep-learning-based ‘organelle segmentation network’ (OrgSegNet), performing pixel-wise segmentation to identify various organelles, is an innovative tool for plant organelle phenotyping and 3D cell reconstruction.Single-nucleus transcriptomes reveal spatiotemporal symbiotic perception and early response in <i>Medicago</i>
Nature Plants, Published online: 25 September 2023; doi:10.1038/s41477-023-01524-8
Single-nucleus transcriptomes uncover cell type-specific gene reprogramming in response to nod factors in Medicago, including a defence response at 30 min, which largely returned to normal at 6 h. The results reveal that MtFER interacts with LYK3 and regulates rhizobial symbiosis.FER meets the Nod factor pathway

Single-nucleus transcriptomic analysis of Medicago roots reveals dynamic cell-specific responses to the Nod factor — a bacterially secreted chito-lipopolysaccharide with a key role in the root nodule symbiosis between legumes and rhizobia — and identifies the receptor-like kinase FERONIA as a phosphorylation target of the Nod factor receptor LYK3, which together function to control nodule formation and bacterial infection.Strikingly convergent genome alterations in two independently evolved holoparasites
Nature Plants, Published online: 21 September 2023; doi:10.1038/s41477-023-01518-6
Two independently evolved lineages of holoparasites — Balanophora (Santalales) and Sapria (Malpighiales) — display massively convergent characteristics of genome modifications, including gene loss in major pathways, reduction of multigene families and generally relaxed selection pressure. These findings provide valuable new insights into the fascinating biology of parasitic plants.
