Transcriptome comparison analyses in UV-B induced AsA accumulation of Lactuca sativa L.

ABSTRACT:

Background

Lettuce (Lactuca sativa L.) cultivated in facilities display low vitamin C (L-ascorbic acid (AsA)) contents which require augmentation. Although UV-B irradiation increases the accumulation of AsA in crops, processes underlying the biosynthesis as well as metabolism of AsA induced by UV-B in lettuce remain unclear.

Results

UV-B treatment increased the AsA content in lettuce, compared with that in the untreated control. UV-B treatment significantly increased AsA accumulation in a dose-dependent manner up until a certain dose.. Based on optimization experiments, three UV-B dose treatments, no UV-B (C), medium dose 7.2 KJ·m^- 2·d^- 1 (U1), and high dose 12.96 KJ·m^- 2·d^- 1 (U2), were selected for transcriptome sequencing (RNA-S
