Spatiotemporal expression profiles of the ZmYSL genes. Real-time quantitative PCR was performed to analyze the expression of the YSL gene in 15 tissues of maize. Total RNA was extracted from the endosperm (En) and the embryo (Em) at the indicated days after pollination (15 and 20 DAP), as well as, from different organs, including l-root (lateral root), c-root (crown root), stem, leaf, sheath, tassel, anther, cob, silk, husk, and seed (10 days after pollination). The Actin1 gene in maize was used for normalizing the relative expression of each gene. The error bars indicate the standard deviation
