Small RNA and Transcriptome Sequencing Reveal a Potential miRNA-Mediated Interaction Network That Functions during Somatic Embryogenesis in Lilium pumilum DC. Fisch.

Plant somatic embryos are widely used in the fields of germplasm conservation, breeding for genetic engineering and artificial seed production. MicroRNAs (miRNAs) play pivotal roles in somatic embryogenesis (SE) regulation. However, their regulatory roles during various stages of SE remain unclear. In this study, six types of embryogenic samples of Lilium pumilum DC. Fisch., including organogen...

Small RNA and degradome sequencing reveal complex miRNA regulation during cotton somatic embryogenesis

MicroRNAs (miRNAs) are endogenous non-coding ~21 nucleotide RNAs that regulate gene expression at the transcriptional and post-transcriptional levels in plants and animals. They play an important role in development, abiotic stress, and pathogen responses. miRNAs with their targets have been widely studied in model plants, but limited knowledge is available on the small RNA population of cotton...

Transcriptome profiling provides insights into dormancy release during cold storage of Lilium pumilum

Background: Bulbs of the ornamental flower Lilium pumilum enter a period of dormancy after flowering in spring, and require exposure to cold for a period of time in order to release dormancy. Previous studies focused mainly on anatomical, physiological and biochemical changes during dormancy release. There are no dormancy studies of the northern cold-hardy wild species of Lilium at the molecula...

Transcriptome and small RNA deep sequencing reveals deregulation of miRNA biogenesis in human glioma.

Altered expression of oncogenic and tumour-suppressing microRNAs (miRNAs) is widely associated with tumourigenesis. However, the regulatory mechanisms underlying these alterations are poorly understood. We sought to shed light on the deregulation of miRNA biogenesis promoting the aberrant miRNA expression profiles identified in these tumours. Using sequencing technology to perform both whole-tr...

Steroidal and phenolic glycosides from the bulbs of Lilium pumilum DC and their potential Na+/K+ ATPase inhibitory activity.

A new steroidal saponin, named pumilum A (1), and a new phenolic glycoside, threo-1-(4'-hydroxy-2'-methoxyphenyl)-2-(2",4"-dihydroxyphenyl)-1,3-propanediol-4'-O-β-D-glucopyranoside (7) were isolated from the methanolic extract of the bulbs of Lilium pumilum DC, along with five known steroidal saponins. Their chemical structures were elucidated on the basis of detailed spectroscopic analysis, in...
