Characterization of Pearl Millet Root Architecture and Anatomy Reveals Three Types of Lateral Roots
Pearl millet plays an important role for food security in arid regions of Africa and India. Nevertheless, it is considered an orphan crop as it lags far behind other cereals in terms of genetic improvement efforts. Breeding pearl millet varieties with improved root traits promises to deliver benefits in water and nutrient acquisition. Here, we characterize early pearl millet root system develop...
متن کاملMeasuring root system architecture: Opportunities and challenges
Root architectural traits are important for the selection of crops and cultivars that are most efficient in the acquisition of nutrients and water from soil. Increasingly laboratory-based methods are being used to screen large numbers of plants and to measure selected architectural traits. Our research with temperate cereals demonstrates that while such methods may allow numbers of root axes an...
متن کاملCapturing Arabidopsis root architecture dynamics with ROOT-FIT reveals diversity in responses to salinity.
The plant root is the first organ to encounter salinity stress, but the effect of salinity on root system architecture (RSA) remains elusive. Both the reduction in main root (MR) elongation and the redistribution of the root mass between MRs and lateral roots (LRs) are likely to play crucial roles in water extraction efficiency and ion exclusion. To establish which RSA parameters are responsive...
متن کاملUntapping 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...
