Chloroplast genomic resources for phylogeny and DNA barcoding: a case study on Fritillaria.

The genus Fritillaria comprises approximately 130 perennial herbaceous species. In the Pharmacopoeia of the People's Republic of China, the bulbs of 11 Fritillaria species are used in Chinese herbal medicines. However, the traditional methods of morphological classification cannot accurately identify closely related species of Fritillaria.

Genome Size Diversity in (Liliaceae) Is Correlated with Karyotype and Environmental Traits.

Genome size (GS) diversity is of fundamental biological importance. The occurrence of giant genomes in angiosperms is restricted to just a few lineages in the analyzed genome size of plant species so far. It is still an open question whether GS diversity is shaped by neutral or natural selection.

Complete chloroplast genome sequences of Lilium: insights into evolutionary dynamics and phylogenetic analyses.

Lilium is a large genus that includes approximately 110 species distributed throughout cold and temperate regions of the Northern Hemisphere. The species-level phylogeny of Lilium remains unclear; previous studies have found universal markers but insufficient phylogenetic signals. In this study, we present the use of complete chloroplast genomes to explore the phylogeny of this genus.

Lilium spp. pollen in China (Liliaceae): taxonomic and phylogenetic implications and pollen evolution related to environmental conditions.

Recent molecular and karyologic studies have significantly modified delimitation of Lilium. However, despite the importance of pollen evolution in the genus comprehensive studies with electron microscopy and evaluation of pollen evolution are lacking. Therefore, we studied pollen morphology in a sample of 65 individuals from 37 taxa covering all the sections distributed in the world, using scanning electron microscopy.

Molecular phylogeny and genetic variation in the genus Lilium native to China based on the internal transcribed spacer sequences of nuclear ribosomal DNA.

We present a comprehensive phylogeny derived from nuclear ribosomal DNA (nrDNA) for 214 samples representing 98 species and five varieties, including 44 species and five varieties native to China. Our collection of 25 species and five varieties (44 samples) covering all five sections of the genus (Comber) distributed in China also were included in the internal transcribed spacer (ITS) database. This study incorporates previous research with an emphasis on Chinese species, including the controversial subsection, Sinomartagon 5c Comber.
