Transcriptome sequencing-based analysis of primary vein development in Betula pendula 'Dalecarlica'.

Keymessage The study revealed the major biological processes occurred at three developmental stages and identified candidate genes involved in primary vein development of birch plants. Vascular tissues usually mirror the surrounding leaf shape and its development plays a fundamental role in plant performance. However, the information of vascular development in birch trees, especially primary vein development, remains unclear.

Ectopic expression of Populus MYB10 promotes secondary cell wall thickening and inhibits anthocyanin accumulation.

Secondary cell wall (SCW) formation is regulated by a multilevel transcriptional regulatory network, in which MYB transcription factors (TFs) play key roles. In woody plants, hundreds of MYB TFs have been identified, most of which have unknown functions in wood SCW biosynthesis. Here, we characterized the function of a Populus MYB gene, PtoMYB10.

Overexpression of Influences Leaf Shape and Internode Development in .

The () gene, which is negatively regulated by (), has been specifically linked to the regulation of leaf margin serration and the maintenance of phyllotaxy in model plants. However, few studies have investigated these effects in woody plants. In this study, we integrated genomic, transcriptomic, and physiology approaches to explore the function of gene in growth and development.

Comparative analysis of growth and photosynthetic characteristics of (Populus simonii × P. nigra) × (P. nigra × P. simonii) hybrid clones of different ploidides.

To evaluate differences among poplar clones of various ploidies, 12 hybrid poplar clones (P. simonii × P. nigra) × (P.
