Untapping root system architecture for crop improvement
Roots are the first organ to sense water deficit, and at the same time they extract virtually all those mineral nutrients from soil that are consumed by humans. Soil resource acquisition under challenging conditions such as drought is a primary limitation on plant productivity, resulting in low yields and thus food insecurity in the poorest countries. Indeed, in overall global agriculture, drou...
متن کاملHope in Change: The Role of Root Plasticity in Crop Yield Stability.
An often underappreciated fact of crop improvement work is that the development of new varieties can take years or even decades (Morrell et al., 2011; Challinor et al., 2016). Because of this, breeders are challenged with developing new varieties in today’s environments that will thrive in those of an uncertain tomorrow. Escalating world food demand in the context of environmental change places...
متن کاملPlasticity of the Arabidopsis root system under nutrient deficiencies.
Plant roots show a particularly high variation in their morphological response to different nutrient deficiencies. Although such changes often determine the nutrient efficiency or stress tolerance of plants, it is surprising that a comprehensive and comparative analysis of root morphological responses to different nutrient deficiencies has not yet been conducted. Since one reason for this is an...
متن کاملEvolutionary Technology and Phenotype Plasticity: The FATINT System
This is a comprehensive summary paper of works done by the authors in 2004-7 but never published as a single narrative. Our works address various aspects of an Evolutionary Technology. We present the challenge, the approach (using simulated interactions from phenotype plasticity called ’fat interactions’) and the first results. On the road, we develop and test a platform for the general agent-b...
متن کاملNon-canonical WOX11-mediated root branching contributes to plasticity in Arabidopsis root system architecture
Lateral roots (LRs), which originate from the growing root, and adventitious roots (ARs), which are formed from non-root organs, are the main contributors to the post-embryonic root system in Arabidopsis However, our knowledge of how formation of the root system is altered in response to diverse inductive cues is limited. Here, we show that WOX11 contributes to root system plasticity. When seed...
