TcLEC2 expression pattern in different cacao tissues. Tissues include: leaves and flowers at different developmental stages, roots and zygotic cotyledons from seeds collected at 14, 16, 18 and 20 weeks after pollination (14 W Cot, 16 W Cot, 18 W Cot and to 20 W Cot respectively). The expression levels were analyzed by qRT-PCR and TcLEC2 gene normalized relative to that of TcTUB1 gene. Bars represent mean values (n = 3; mean ± SE). Significance was established by t-test (**represents p-value < 0.01by t-test; *represents p-value < 0.05 by t-test).
