Abstract:
We present a genome assembly of Paulownia tomentosa (empress tree; Streptophyta; Magnoliopsida; Lamiales; Paulowniaceae). The assembly consists of two haplotypes with total lengths of 523.45 megabases and 513.68 megabases. The haplotype 1 assembly and the haplotype 2 assembly each contain 20 chromosomal pseudomolecules; these account for 99.88% and 94.87% of their respective sequences. The mitochondrial genome assembly has a length of 877.79 kilobases and the plastid genome assembly has a length of 154.65 kilobases. Gene annotation of the haplotype 1 assembly by Ensembl identified 27,612 protein-coding genes. This assembly was generated as part of the Darwin Tree of Life project, which produces reference genomes for eukaryotic species found in Britain and Ireland.

Transgenic Plants
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...
