Relative expression of nine selected lncRNAs by qPCR collected from shoot apical meristem samples in 5 different growth stages in two different lettuce genotypes, Qomi (early bolting) and Sefid-e-Neishabour (late bolting). Q, SN, D, S, and F represent Qomi, Sefid-e-Neishabour, days after planting, flowering and shoot apical meristem, respectively. The examined days after planting are included; 10, 20, 30, and 40. Bars display mean values of three replicates (+/− standard deviation). *p-value < 0.05 and **p-value < 0.01 indicate significant differences
