Transcriptome Analysis Reveals Coexpression Networks and Hub Genes Involved in Papillae Development in .

is a genus of important ornamental plants with many colouring pattern variations. is the parent of Oriental hybrid lilies. A typical feature of is the presence of red-orange special raised spots named papillae on the interior tepals.

Integrated mRNA and small RNA sequencing reveals a regulatory network associated with flower color in oriental hybrid lily.

Anthocyanins are one of the main components of pigments, that are responsible for a wide range of colors in plants. To clarify the regulatory mechanism of anthocyanin biosynthesis in oriental hybrid lily, UPLC/MS analysis was performed to identify the pigments in two cultivars (white and pink). Four major anthocyanins were identified in pink cultivar, and no anthocyanins were detected in white cultivar.

Functional analysis and expression patterns of members of the FLOWERING LOCUS T (FT) gene family in Lilium.

Lilium is an important commercial flowering species, and there are many varieties and more than 100 species of wild Lilium. Lilium × formolongi is usually propagated from seedlings, and the flowering of these plants is driven mainly by the photoperiodic pathway. Most of the other lily plants are propagated via bulblets and need to be vernalized; these plants can be simply divided into pretransplantation types and posttransplantation types according to the time at which the floral transition occurs.

Genome-Wide Analysis of the Cyclin Gene Family and Their Expression Profile in .

Cyclins, together with highly conserved cyclin-dependent kinases (CDKs), play an important role in the process of cell cycle in plants, but less is known about the functions of cyclins in legume plants, especially . Our genome-wide analysis identified 58, 103, and 51 cyclin members in the , , and genomes. Phylogenetic analysis suggested that these cyclins could be classified into 10 types, and the CycB-like types (CycBL1-BL8) were the specific subgroups in , which was one reason for the expansion of the B-type in .

Genome-Wide Characterization, Evolution, and Expression Analysis of the Leucine-Rich Repeat Receptor-Like Protein Kinase (LRR-RLK) Gene Family in .

Leucine-rich repeat receptor-like kinases (LRR-RLKs) constitute the largest subfamily of receptor-like kinases (RLKs) in plants. They play roles in plant growth and developmental and physiological processes, but less is known about the functions of LRR-RLKs in . Our genome-wide analysis revealed 329 genes in the genome.

The lre-miR159a-LrGAMYB pathway mediates resistance to grey mould infection in Lilium regale.

Grey mould is one of the most determinative factors of lily growth and plays a major role in limiting lily productivity. MicroRNA159 (miR159) is a highly conserved microRNA in plants, and participates in the regulation of plant development and stress responses. Our previous studies revealed that lre-miR159a participates in the response of Lilium regale to Botrytis elliptica according to deep sequencing analyses; however, the response mechanism remains unknown.

Analysis of WRKY transcription factors and characterization of two Botrytis cinerea-responsive LrWRKY genes from Lilium regale.

A major constraint in producing lilies is gray mold caused by Botrytis elliptica and B. cinerea. WRKY transcription factors play important roles in plant immune responses.

Evaluation of resistance to Botrytis elliptica in Lilium hybrid cultivars.

Gray mold disease, caused by the fungus Botrytis elliptica, is one of the major diseases affecting Lilium species, and it has become a limiting factor in the production of ornamental lilies. To support selecting and breeding Botrytis-resistant cultivars, a total of 50 Lilium cultivars belonging to seven hybrid types were evaluated using a detached leaf technique for resistance to B. elliptica.

Transcriptome-Wide Analysis of Responsive microRNAs and Their Targets in Wilson by High-Throughput Sequencing and Degradome Analysis.

MicroRNAs, as master regulators of gene expression, have been widely identified and play crucial roles in plant-pathogen interactions. A fatal pathogen, , causes the serious folia disease of lily, which reduces production because of the high susceptibility of most cultivated species. However, the miRNAs related to infection of lily, and the miRNA-mediated gene regulatory networks providing resistance to in lily remain largely unexplored.

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.

Identification of legume RopGEF gene families and characterization of a Medicago truncatula RopGEF mediating polar growth of root hairs.

Root hairs play important roles in the interaction of plants with their environment. Root hairs anchor the plant in the soil, facilitate nutrient uptake from the rhizosphere, and participate in symbiotic plant-microbe interactions. These specialized cells grow in a polar fashion which gives rise to their elongated shape, a process mediated in part by a family of small GTPases known as Rops.
