In the last two decades, work on auxin signaling has helped to understand many aspects of the fundamental process underlying the specification of tissue types in the plant embryo. However, the immediate steps after fertilization including the polarization of the zygote and the initial body axis formation remained poorly understood. Valuable insight into these enigmatic processes has been gained by studying fertilization in grasses. Recent technical advances in transcriptomics of developing embryos with high spatial and temporal resolution give an emerging picture of the rapid changes of the zygotic developmental program. Together with the use of live imaging of novel fluorescent marker lines, these data are now the basis of unraveling the very first steps of the embryonic patterning process.

平方一：开花植物中的合子极性和早期胚胎发生。

在过去的二十年中，关于植物生长素信号转导的研究有助于了解植物胚中组织类型规范基础的基本过程的许多方面。然而，受精后的立即步骤，包括合子的极化和最初的体轴形成，仍然知之甚少。通过研究草中的施肥，已经获得了对这些神秘过程的宝贵见解。发展具有高时空分辨率的胚胎的转录组学的最新技术进展为合子发育程序的快速变化提供了新的图景。现在，结合使用新型荧光标记物的实时成像技术，这些数据已成为阐明胚胎构图过程第一步的基础。
