Key message The present study revealed many functional molecules for leaf splitting during the apical bud development and the switch development from the apical buds to leaf marginal tissues. Abstract The lobe, an important character of leaf architecture, is present in Betula pendula ‘Dalecarlica’. The presence of split lobes is of great significance in plant growth and development. The molecular...
Lobe, a visual description of leaf morphology, is present in Betula pendula ‘Dalecarlica’. Although works involving leaf dehiscence have been conducted, knowledge on the genetic regulation of leaf morphology diversity at early stage remains largely elusive. Here, based on the extent of leaf margin variability, trees of B. pendula ‘Dalecarlica’ were categorized into A, B, and C. Plant materials of...
Plant researchers have focused much attention on leaf shape because of its importance in the identification. To evaluate the impact of intraspecies leaf-shape variation on the transcriptome, a series of Betula pendula ‘Dalecarlica’ and B. pendula saplings were generated through tissue culture. The leaf shapes and transcriptomes of B. pendula ‘Dalecarlica’ clones were compared with those of B. pendula...
‘Purple Rain’, a purple cultivar of Betula pendula, has dark purple leaves throughout the vegetative period. In this study, B. pendula ‘Purple Rain’ was found to have a higher anthocyanidin level compared with B. pendula, Transcriptome analysis revealed numerous changes in gene expression that could be attributed to color change, including the upregulation of 2467 unigenes and the downregulation of...
