Global characterization of the root transcriptome of a wild species of rice, Oryza longistaminata, by deep sequencing.

ABSTRACT:

Background

Oryza longistaminata, an AA genome type (2 n = 24), originates from Africa and is closely related to Asian cultivated rice (O. sativa L.). It contains various valuable traits with respect to tolerance to biotic and abiotic stress, QTLs with agronomically important traits and high ability to use nitrogen efficiently (NUE). However, only limited genomic or transcriptomic data of O. longistaminata are currently available.

Results

In this study we present the first comprehensive characterization of the O. longistaminata root transcriptome using 454 pyrosequencing. One sequencing run using a normalized cDNA library from O. longistaminata roots adapted to low N conditions generated 337,830 reads, which assembled into 41,189 contigs and 30,178 singletons.
