Rooting plant development.
In 1993, we published a paper in Development detailing the anatomical structure of the Arabidopsis root. The paper described how root growth was maintained by the precisely tuned activity of a small set of 'initials', which acted as the source of dividing and differentiating cells, and how these stem cell-like cells surrounded a few infrequently dividing cells. This work underpinned subsequent ...
متن کاملS08-03 Development of land plant rooting structures
The anterior foregut of the mammalian embryo initially consists of a simple epithelial tube surrounded by undifferentiated mesoderm. As development proceeds this tube separates into two – the dorsal esophagus and the ventral trachea – while the primary lung buds at the distal end of the trachea undergo extensive branching morphogenesis to give rise to the lungs. The simple epithelium in each re...
متن کاملHydrologic regulation of plant rooting depth.
Plant rooting depth affects ecosystem resilience to environmental stress such as drought. Deep roots connect deep soil/groundwater to the atmosphere, thus influencing the hydrologic cycle and climate. Deep roots enhance bedrock weathering, thus regulating the long-term carbon cycle. However, we know little about how deep roots go and why. Here, we present a global synthesis of 2,200 root observ...
متن کاملRooting Gene Trees without Outgroups: EP Rooting
Gene sequences are routinely used to determine the topologies of unrooted phylogenetic trees, but many of the most important questions in evolution require knowing both the topologies and the roots of trees. However, general algorithms for calculating rooted trees from gene and genomic sequences in the absence of gene paralogs are few. Using the principles of evolutionary parsimony (EP) (Lake J...
متن کاملEffect of Plant Growth Regulators on Rooting of Henna (Lawsonia Inermis L.)
Studies have shown that rooting substrate is one of the effective factors at rooting of hard rhizogenetic plant such as Henna. The purpose of this study is to determine an appropriate concentration of Naphthalene Acetic Acid (NAA), Indole Butyric Acid (IBA) and salicylic acid (SA) on Rooting of Henna. Present study showed that there was a great variation in most of the measured characters at P<...
