Hemsl. (Thymelaeaceae) is an evergreen shrub plant. First, we characterized the complete nucleotide sequence of chloroplast (cp) genome of . The total length of cp genome was found to be 170,553 bp, including a large single copy (LSC) region of 84,886 bp, a small single copy (SSC) region of 2,437 bp, and a pair of inverted repeats (IRs) of 41,617 bp. The cp genome of Hemsl. contains 134 genes, including 90 protein-coding genes (75 PCG species), 37 transfer RNA genes (29 tRNA species), and 6 rRNA genes (3 RNA species). A total of 13 genes (, , , , , , , , , , , and ) contain a single intron, and one gene () contains two introns. The GC content in whole cp genome, LSC region, SSC region, and IR region was 36.75%, 34.83%, 28.19%, and 38.96% respectively, like other Thymelaeaceae plants. Phylogenetic analysis suggested that has a close relationship with congeneric .

Unlabelled: Orphan genes (OGs), also known as lineage-specific genes, are species-specific genes that play a crucial role in species-specific adaptations to various stresses. Although OGs have been identified in several plant species, there is no information on OGs in banana genomes. This study aimed to systematically identify OGs in twelve banana (sub)species using comparative genomics.

Background: The confused taxonomic classification of Crucigenia is mainly inferred through morphological evidence and few nuclear genes and chloroplast genomic fragments. The phylogenetic status of C. quadrata, as the type species of Crucigenia, remains considerably controversial.

The family Daphniphyllaceae has a single genus, and no relevant comparative phylogenetic study has been reported on it. To explore the phylogenetic relationships and organelle evolution mechanisms of Daphniphyllaceae species, we sequenced and assembled the chloroplast and mitochondrial genomes of Daphniphyllum macropodum. We also conducted comparative analyses of organelles in Daphniphyllaceae species in terms of genome structure, phylogenetic relationships, divergence times, RNA editing events, and evolutionary rates, etc.

Background: Assessing the current status and identifying the mechanisms threatening endangered plants are significant challenges and fundamental to biodiversity conservation, particularly for protecting Tertiary relict trees and plant species with extremely small populations (PSESP). Ulmus elongata (Ulmus, Ulmaceae) with high values for the ornamental application, is a Tertiary relict tree species and one of the members from PSESP in China. Currently, the wild populations of U.
