RNA sequencing of leaf lettuce grown under blue, red or white light

Lettuce (Lactuca sativa) belongs to Asteraceae family, grown in various parts of the world for use as a leafy vegetable. Although the application of light-emitting diode (LED) in controlled plant production systems have been successfully used to enhance nutritional quality and plant growth efficiently, molecular basis of plant response to physical factors such as light quality on plants in general and on leafy vegetable crops in particular are scarce. In this study, we sequenced and de novo assembled the transcriptomes of leaf lettuce (Lactuca sativavar. 'New Red Fire) grown hydroponically in a modular agricultural production system under three different types of LED lighting: red, blue and white light.
