Abstract
Plant post-embryonic development is characterized by the unceasing generation of new tissues and organs that allow plants to adapt their growth and architecture to environmental conditions. Primary root indeterminate growth is sustained by the activity of the root apical meristem (RAM), an organized structure containing stem cells that continuously divide to generate new tissues. RAM, thanks to its simple and symmetric structure, is an excellent system for studying how hormone distributions and interactions regulate growth. Plant hormones are pivotal actors in establishing and maintaining RAM patterning, and their developmental outputs are dependent on their integrated activities. In this review, we discuss recent findings on hormonal crosstalk that shapes the root meristem, focusing our attention on both the root radial and longitudinal axes.
期刊介绍：
Cell Reports publishes high-quality research across the life sciences and focuses on new biological insight as its primary criterion for publication. The journal offers three primary article types: Reports, which are shorter single-point articles, research articles, which are longer and provide deeper mechanistic insights, and resources, which highlight significant technical advances or major informational datasets that contribute to biological advances. Reviews covering recent literature in emerging and active fields are also accepted.
The Cell Reports Portfolio includes gold open-access journals that cover life, medical, and physical sciences, and its mission is to make cutting-edge research and methodologies available to a wide readership.
The journal's professional in-house editors work closely with authors, reviewers, and the scientific advisory board, which consists of current and future leaders in their respective fields. The advisory board guides the scope, content, and quality of the journal, but editorial decisions are independently made by the in-house scientific editors of Cell Reports.
