The relative expression patterns of pre-miR408 and dlo-miR408 members in different early SE and different tissues of longan. EC, embryogenic callus; ICpEC, incomplete compact pro-embryogenic cultures; CpECGE, compact pro-embryogenic cultures globular embryos; GE, globular embryo. The different early SE of longan are induced according to Lai (2003). Error bars indicate means ± SDs, n = 3. *P ≤ 0.05, **P ≤ 0.01.
