Anthracnose symptoms severely occurred up to 100% on leaves of May lily grown in four locations in Korea during a disease survey in 2001. The symptoms appeared as circular to irregular spots with brown to dark brown discoloration on leaves of the plant, and severely infected leaves blighted. A total of 35 isolates of Colletotrichum sp. was obtained from the spotted lesions and identified as Colletotrichum liliacearum based on the morphological and cultural characteristics. Leaf spots similar to the original anthracnose symptoms were induced on the host leaves by artificial inoculation with the isolates of the fungus. This is the first report that C. liliacearum causes anthracnose of May lily.

The biological characteristics,agronomic traits,yield traits,stress resistance,quality and photosynthetic characteristics among six lily varieties were compared in order to screen out the excellent lily varieties suitable for spread planting in Hunan province. Lilium longiflorum had the longest growth period,246 days,among these six lily varieties,while others were about 170 days. The leaves of L.longiflorum,self-selected variety,L. lancifolium and L. dauricum had higher chlorophyll content. No obvious difference was found in net photosynthetic rate,stomatal conductance,transpiration rate and intercellular CO2 concentration among all varieties. The self-selected variety had the highest theoretical and actual yield,2 543. 03,1 608. 65 kg per Mu(1 Mu≈666. 7 m2),respectively,but contents of polysaccharides and flavones in bulbs were lower. All of these six lily varieties can sowing,seedling emergence,growth,flowering,mature harvest in Hunan province. L. dauricum and L. lancifolium would be provided for edible lily. L. brownie and the self-selected variety are highly susceptible varieties. L. dauricum and L. lancifolium are suitable to plant widely in disease-prone regions,due to their strong resistance. L. brownie and L. lancifolium are preferred varieties for medicinal and food using for their good quality and higher contents of polysaccharides and flavones. L. davidii had lower theoretical and actual yield,so planting extension of it should be taken into account.

Genetic diversity of Lilium sargentiae was detected in this paper by sequence-related amplified polymorphism (SRAP) marker. One hundred wild samples were collected from 10 places, and 15 SRAP primer combinations were used for determination. NTSYS-pc2.1 and POPGEN1.32 were used for data analysis. The results showed that a total of 170 clear DNA bands were amplified, 163 of which were polymorphic. The proportion of polymorphic loci was 90.58% on the level of species. Nei's (1973) gene diversity (H) was 0.2631, Shannon's Information index was 0.3661, the G(st), was 0.3672, and the genetic distance ranged from 0.2021 to 0.5749. All materials could be clustered into four groups by UPGMA. The results demonstrated that the genetic diversity of L. sargentiae was rich on the level of species, and the genetic diversity within populations exceeded among populations. The correlations of genetic diversity and distribution were significant in L. sargentiae.

To establish a new method for identifying genus of Lilium by DNA barcoding technology, ITS, ITS2, psbA-trnH, matK and rbcL sequences were analyzed in term of variation of inter- and intra-species, barcoding gap, neighbor-joining tree to distinguish genus of Lilium based on 978 sequences from experimental and GenBank database, and identification efficiency was evaluated by Nearest distance and BLAST1 methods. The results showed that DNA barcoding could identify different species in genus of Lilium. ITS sequence performed higher identification efficiency, and had significant difference between intra- and inter-species. And NJ tree could also divide species into different clades. Results indicate that DNA barcoding can identify genus of Lilium accurately. ITS sequence can be the optimal barcode to identify species of Lilium.

Supernumerary B chromosomes were found in Lilium amabile (2n = 2x = 24), an endemic Korean lily that grows in the wild throughout the Korean Peninsula. The extra B chromosomes do not affect the host-plant morphology; therefore, whole transcriptome analysis was performed in 0B and 1B plants to identify differentially expressed genes. A total of 154,810 transcripts were obtained from over 10 Gbp data by de novo assembly. By mapping the raw reads to the de novo transcripts, we identified 7,852 differentially expressed genes (log₂FC > |10|), in which 4,059 and 3,794 were up-and down-regulated, respectively, in 1B plants compared to 0B plants. Functional enrichment analysis revealed that various differentially expressed genes were involved in cellular processes including the cell cycle, chromosome breakage and repair, and microtubule formation; all of which may be related to the occurrence and maintenance of B chromosomes. Our data provide insight into transcriptomic changes and evolution of plant B chromosomes and deliver an informative database for future study of B chromosome transcriptomes in the Korean lily.

To clarify the species and preparation of " Baihe"( Lilii Bulbus),a traditional Chinese medicine,we investigated the relative ancient Chinese literature on this medicine. The study concluded that Lilium brownii var. viridulum is the authentic lily for medical use. In the Ben Cao Yan Yi and some medical books in the Ming and Qing Dynasties,L. lancifolium( Juandan) was also mistakenly used as genuine lily,but most doctors believe that this variety should not be used for medicinal purposes; L. pumilum( Shandan)began to be used as a medicine from Ri Hua Zi Ben Cao,but mainly for surgery,the effect is also different from L. brownii var. viridulum. We suggested Shandan be used as the species for another medicine as " Hong Bai He( red lily) " due to its red flower. All above three species recorded in the Chinese Pharmacopoeia are not corresponded to the condition of ancient doctors' uses. Therefore,as for developing of traditional classical formula,L. brownii var. viridulum should be chosen and used as Baihe. The birth places for Baihe include Gansu,Hubei,Anhui and Shandong province. The drug preparations of Baihe include crude medicine,roasting and steaming,which preparation should be chosen depends on the formula which contains Baihe.

Although the number of protein-coding genes is not highly variable between plant taxa, the DNA content in their genomes is highly variable, by as much as 2,056-fold from a 1C amount of 0.0648 pg to 132.5 pg. The mean 1C-value in plants is 2.4 pg, and genome size expansion/contraction is lineage-specific in plant taxonomy. Transposable element fractions in plant genomes are also variable, as low as ~3% in small genomes and as high as ~85% in large genomes, indicating that genome size is a linear function of transposable element content. Of the 2 classes of transposable elements, the dynamics of class 1 long terminal repeat (LTR) retrotransposons is a major contributor to the 1C value differences among plants. The activity of LTR retrotransposons is under the control of epigenetic suppressing mechanisms. Also, genome-purging mechanisms have been adopted to counter-balance the genome size amplification. With a wealth of information on whole-genome sequences in plant genomes, it was revealed that several genome-purging mechanisms have been employed, depending on plant taxa. Two genera, Lilium and Fritillaria, are known to have large genomes in angiosperms. There were twice times of concerted genome size evolutions in the family Liliaceae during the divergence of the current genera in Liliaceae. In addition to the LTR retrotransposons, non-LTR retrotransposons and satellite DNAs contributed to the huge genomes in the two genera by possible failure of genome counter-balancing mechanisms.
