Global identification of post-transcriptional modification of Limonium bicolor during salt gland development

Halophytes, the native growth community in saline environment, provide a salt-resistance gene source for transforming crops under the situation of saline expansion worldwide. Limonium bicolor, widely recognized as sea lavender in horticultural flowers, is a typical recreto-halophyte with salt gland in the epidermis to excrete the excessive Na+ out of the plants. Though many candidate genes are proposed during salt gland initiation and development, the detailed alternative splicing (AS) and alternative polyadenylation (APA) are largely unknown during salt gland development. Here, we applied a single-molecule long-read isoform sequencing (Iso-seq) technique to explore the complex transcriptome of L. bicolor in salt gland initiation stage A and salt gland differentiation stage B at the isoform level.
