Connecting emerging with existing vasculature above and below ground

Curr Opin Plant Biol. 2023 Sep 27;76:102461. doi: 10.1016/j.pbi.2023.102461. Online ahead of print.ABSTRACTThe vascular system was essential for plants to colonize land by facilitating the transport of water, nutrients, and minerals throughout the body. Our current knowledge on the molecular-genetic control of vascular tissue specification and differentiation is mostly based on studies in the Arabidopsis primary root. To what degree these regulatory mechanisms in the root meristem can be extrapolated to vascular tissue development in other organs is a question of great interest. In this review, we discuss the most recent progress on cotyledon vein formation, with a focus on polar auxin transport-dependent and -independent mechanisms. We also provide an overview of vasculature formation in postembryonic organs, namely lateral roots, which is more complex than anticipated as several tissues of the parent root must act in a spatio-temporally coordinated manner.PMID:37774454 | DOI:10.1016/j.pbi.2023.102461
