Putting Down Roots: How Nitrate and Abscisic Acid Help Shape Root System Architecture.
Nitrate has profound effects on plant growth and development. Adequate nitrate levels inhibit lateral root growth, as the plant senses it has all the nitrate it needs. Conversely, a patch of nitrate in poor soil triggers the initiation or elongation of lateral roots, a remarkably plastic process that requires the interplay of nitrate sensing and auxin signaling pathways (Krouk et al., 2010). Th...
متن کاملAbscisic Acid: Hidden Architect of Root System Structure
Plants modulate root growth in response to changes in the local environment, guided by intrinsic developmental genetic programs. The hormone Abscisic Acid (ABA) mediates responses to different environmental factors, such as the presence of nitrate in the soil, water stress and salt, shaping the structure of the root system by regulating the production of lateral roots as well as controlling roo...
متن کاملPutting Down Roots: A Graphical Exploration of Community Attachment
In this paper, we explore the relationships that individuals have with their communities. This work was prepared as part of the ASA Data Expo ‘13 sponsored by the Graphics Section and the Computing Section, using data provided by the Knight Foundation Soul of the Community survey. The Knight Foundation in cooperation with Gallup surveyed 43,000 people over three years in 26 communities across t...
متن کاملRoot System Architecture from Coupling Cell Shape to Auxin Transport
Lateral organ position along roots and shoots largely determines plant architecture, and depends on auxin distribution patterns. Determination of the underlying patterning mechanisms has hitherto been complicated because they operate during growth and division. Here, we show by experiments and computational modeling that curvature of the Arabidopsis root influences cell sizes, which, together w...
متن کاملFood for thought: how nutrients regulate root system architecture
The spatial arrangement of the plant root system (root system architecture, RSA) is very sensitive to edaphic and endogenous signals that report on the nutrient status of soil and plant. Signalling pathways underpinning RSA responses to individual nutrients, particularly nitrate and phosphate, have been unravelled. Researchers have now started to investigate interactive effects between two or m...
