“…In the broadly used PoiseuilleHagen model, only the quantity and diameter of xylem vessels are accounted for. Yet, it is known for a long time that xylem porous plates, pit membranes and persistent primary crosswalls limit root axial conductivity [108][109][110][111][112][113] and affect the partitioning of water uptake among root types [27] . …”

In the recent years, many computational tools, such as image analysis, data management, processbased simulation and upscaling tools, were developed to help quantify and understand water flow in the soilroot system, at multiple scales (tissue, organ, plant and population). Several of these tools work together or, at least, are compatible. However, for the uninformed researcher, they might seem disconnected, forming a unclear and disorganised succession of tools.In this article, we present how different pieces of work can be further developed by connecting them to analyse soilrootwater relations in a comprehensive and structured network. This "explicit network of soilroot computational tools" informs the reader about existing tools and help them understand how their data (past and future) might fit within the network. We also demonstrate the novel possibilities of scaleconsistent parameterizations made possible by the network with a set of case studies from the literature. Finally, we discuss existing gaps in the network and how we can move forward to fill them..

Aerial Root Physiology: Reaching for the Sky or Down to Earth?

Aerial roots have evolved in plants from diverse ecosystems, many facing specific environmental challenges associated with their natural or agricultural setting. In coastal species exposed to wind and waves, including mangroves, soft anoxic substrates have resulted in highly developed aerial root systems. In the rainforest, aerial roots of hemi‐epiphytic figs enable life to begin higher in the canopy while climbing plants, such as ivy and Monstera s, depend on structurally very different aerial roots to climb vertical substrates. Maize, globally one of the three most important cereals, develops aerial roots presumably reducing lodging in high winds. In each of these cases, the dominant hypothesized role for aerial roots is to provide support and enabling greater heights to be reached. But do aerial roots of these plant groups also contribute to resource uptake and movement? This article explores the current knowledge of aerial root physiology and structure from each of these interesting and challenging environmental conditions and discusses how understanding these adaptations and niche requirements has value for improving crops, protecting our coastlines, improving our urban green spaces, and managing biodiversity conservation.

Plant root systems are critical to plant health and productivity, but have been difficult to study due to their subterranean location. From the studies that have been completed, there is evidence that root type matters for both developmental mechanisms and root function. Roots can be divided into different types based on the plant grouping (eudicot versus monocot) or developmental point of origin (embryonic versus post‐embryonic). This article focuses on the post‐embryonic nodal roots of the monocot Zea mays (maize). Maize is the number one cultivated cereal crop worldwide, yet there is limited knowledge about the mature root system. This article presents what is known about the anatomy, morphology, genetic and molecular mechanisms, and environmental factors of maize nodal root development, as well as the current state of knowledge for nodal root function including water and nutrient uptake, symbioses, and lodging resistance. As the world population grows and the climate changes, maize nodal root development and function is one area that can be targeted to improve yield and stress resilience.
