Differential miRNA expression in Rehmannia glutinosa plants subjected to continuous cropping.

ABSTRACT:

Background

The productivity of the medicinally significant perennial herb Rehmannia glutinosa is severely affected after the first year of cropping. While there is some information available describing the physiological and environmental causes of this yield decline, there is as yet no data regarding the changes in gene expression which occur when the species is continuously cropped.

Results

Using a massively parallel (Solexa) DNA sequencing platform, it was possible to identify and quantify the abundance of a large number of R. glutinosa miRNAs. We contrasted the miRNA content of first year crop plants with that of second year crop ones, and were able to show that of 89 conserved (belonging to 25 families) and six novel miRNAs (six families), 29 of the former and three of t
