Differential expression of miRNAs in response to salt stress in maize roots.

ABSTRACT:

Background and aims

Corn (Zea mays) responds to salt stress via changes in gene expression, metabolism and physiology. This adaptation is achieved through the regulation of gene expression at the transcriptional and post-transcriptional levels. MicroRNAs (miRNAs) have been found to act as key regulating factors of post-transcriptional gene expression. However, little is known about the role of miRNAs in plants' responses to abiotic stresses.

Methods

A custom microparaflo microfluidic array containing release version 10.1 plant miRNA probes (http://microrna.sanger.ac.uk/) was used to discover salt stress-responsive miRNAs using the differences in miRNA expression between the salt-tolerant maize inbred line 'NC286' and the salt-sensitive maize line 'Huangzao4'.
