Iris lactea var. chinensis plant drought tolerance possibly depends on response of proline metabolism, transcription factors, transporters and ROS scavenging system

Iris lactea var. chinensis, a perennial herb, is widely distributed and possesses good drought tolerant traits. However, there is less information concerning this herb research in public databases, so it is difficult to understand underlying mechanism of the plant drought tolerance. Here, we conducted RNA-seq analysis of I. lactea plants treated with drought stress and rehydration by the Illumina sequencing technology to explore potential mechanism in plant drought tolerance
