Functional Characterization of 4'OMT and 7OMT Genes in BIA Biosynthesis.

Alkaloids are diverse group of secondary metabolites generally found in plants. Opium poppy (Papaver somniferum L.), the only commercial source of morphinan alkaloids, has been used as a medicinal plant since ancient times.

Regulation of the alkaloid biosynthesis by miRNA in opium poppy.

Opium poppy (Papaver somniferum) is an important medicinal plant producing benzylisoquinoline alkaloids (BIA). MicroRNAs (miRNAs) are endogenous small RNAs (sRNAs) of approximately 21 nucleotides. They are noncoding, but regulate gene expression in eukaryotes.

Boron stress responsive microRNAs and their targets in barley.

Boron stress is an environmental factor affecting plant development and production. Recently, microRNAs (miRNAs) have been found to be involved in several plant processes such as growth regulation and stress responses. In this study, miRNAs associated with boron stress were identified and characterized in barley.

Genome-wide identification of miRNAs responsive to drought in peach (Prunus persica) by high-throughput deep sequencing.

Peach (Prunus persica L.) is one of the most important worldwide fresh fruits. Since fruit growth largely depends on adequate water supply, drought stress is considered as the most important abiotic stress limiting fleshy fruit production and quality in peach.
