(Batal.) Iljinskaja, a monotypic species in of Juglandaceae, is regarded as one of important medical plants in China. In order to reveal the alterations in chloroplast (cp) genome with nuclear genome duplication, we presented the complete cp genomes of , and firstly analyzed on the basis of ploidy type (tetraploid and diploid ). The total length of the cp genome of tetraploid and diploid is 160,938 and 161,105 bp, respectively. Both type genome consist of a large single-copy (LSC) region (90,221 and 90,391 bp), a small single-copy (SSC) region (18,593 and 18,590 bp), and an pair of invert repeats (IRs) regions (26,062 and 26,062 bp). Tetraploid and diploid plastid genome contain 132 and 137 genes, 87 and 88 protein-coding genes, 37 and 39 genes, and both eight genes, respectively. Closely phylogenetic relationship by analyzing 23 cp genomes suggests that tetraploid probably originated from diploid .

The genetic, morphological and taxonomic diversity of the genus is due to homoploid and polyploid hybridisation, autopolyploidy and apomixis, which also influence the production and diversity of secondary metabolites, especially flavonoids. The aim of this study was to investigate the relationships and variations of flavonoids in terms of hybrid origin and ploidy level between the parental species and their hybrid derivatives. The sampling design included leaf material of the following accessions from ten natural localities: parental taxa (di-, tri- and tetraploids of ; diploid and ) and their di-, tri- and tetraploid hybrid derivatives from crosses of × (subg.

(Orchidaceae) boasts high ornamental value due to its pleasant aroma, foxtail spike, and elegant floral morphology. Inducing to become tetraploid enhances horticultural traits and facilitates fertile intergeneric hybrids through crosses with other market-available tetraploid species. The experimental design involved the application of colchicine at varying concentrations-0.

Plant plasma membrane (PM) H-ATPase functions as a proton-motive force by exporting cellular protons to establish a transmembrane chemical gradient of H ions and an accompanying electrical gradient. These gradients are crucial for plant growth and development and for plant responses to abiotic and biotic stresses. In this study, a comprehensive identification of the PM H-ATPase gene family was conducted across four cotton species.

With advances in long-read sequencing and assembly techniques, haplotype-resolved (phased) genome assemblies are becoming more common, also in the field of plant genomics. Computational tools to effectively explore these phased genomes, particularly for polyploid genomes, are currently limited. Here we describe a new strategy adopting a pangenome approach.

Following the identification of the self-compatibility gene () in diploid potatoes two decades ago, the breeding of inbred based diploid hybrid potatoes made its way. Tetraploid potatoes have a long history of cultivation through domestication and selection. Tetrasomic inheritance, heterozygosity and clonal propagation complicate genetic studies, resulting in a low genetic gain in potato breeding.
