RNAseq of leaf tissue of Medicago truncatula R108 WT and mtftb1/2 gene-edited double mutant at two different developmental stages and vernalised conditions

We have found that MtFTb genes play a role in the response to LD conditions, both under vernalized and non-vernalized conditions. To explore the regulatory gene network downstream of FTb genes on a global scale, we performed RNA sequencing of the gene-edited Mtftb1/b2 vs WT plants. For this, we grew wild-type and gene-edited Mtftb1/2 plants under two different conditions: vernalised long days (VLD), where the plants were vernalized for 14 days and then grown for two weeks under LD photoperiod, with the aim of capture changes in expression profiles in the period in which the plant becomes physiologically committed to flower; the second condition was non-vernalised long days (NVLD), where non-vernalized plants were grown for 60 days, a crucial time point when wild-type plants typically undergo the transition to flowering. This approach allowed us to investigate the gene expression changes in the FTb1/2 mutant independent of vernalization effects.
