Dissection of early transcriptional responses to water stress in Arundo donax L. by unigene-based RNA-seq.

ABSTRACT:

Background

Arundo donax L. (Poaceae) is considered one of the most promising energy crops in the Mediterranean region because of its high biomass yield and low input requirements, but to date no information on its transcriptional responses to water stress is available.

Results

We obtained by Illumina-based RNA-seq the whole root and shoot transcriptomes of young A. donax plants subjected to osmotic/water stress with 10 and 20 % polyethylene glycol (PEG; 3 biological replicates/organ/condition corresponding to 18 RNA-Seq libraries), and identified a total of 3034 differentially expressed genes. Blast-based mining of stress-related genes indicated the higher responsivity of roots compared to shoots at the early stages of water stress especially under the milder PEG treatment,
