Diversity of Root System Architecture in Mediterranean Maize Inbred Lines Provides New Breeding Opportunities to Improve Stress Resilience and Resource Efficiency [PDF]

Plants
A detailed characterization of root system architecture (RSA) and growth dynamics is key to develop stress-resilient maize varieties. We evaluated sixty-five Mediterranean maize inbred lines using automated high-throughput phenotyping under controlled ...

Nitrate and phosphate availability and distribution have different effects on root system architecture of Arabidopsis [PDF]

Plant Journal, 2002
Plant root systems can respond to nutrient availability and distribution by changing the three-dimensional deployment of their roots: their root system architecture (RSA). We have compared RSA in homogeneous and heterogeneous nitrate and phosphate supply

Melatonin: a multifaceted regulator of root development, stress responses, and hormonal crosstalk in horticultural crops [PDF]

Frontiers in Plant Science
Melatonin is increasingly recognized as a multifunctional signaling molecule involved in plant growth regulation and stress adaptation. Recent studies have revealed that melatonin plays a pivotal role in shaping root system architecture (RSA) by ...

Evolving technologies for growing, imaging and analyzing 3D root system architecture of crop plants [PDF]

Journal of Integrative Plant Biology, 2016
A plant's ability to maintain or improve its yield under limiting conditions, such as nutrient deficiency or drought, can be strongly influenced by root system architecture (RSA), the three-dimensional distribution of the different root types in the soil.

Genome-wide association study of Ethiopian barley germplasm reveals putative genomic loci underlying root system architectural traits at seedling stage [PDF]

BMC Plant Biology
Background The root system architectural (RSA) trait is one of the factors that contribute to yield. In the current situation, developing new crop cultivars with efficient RSA has great potential to enhance soil resource use efficiency and improve crop ...

Combined Genome-Wide Association Studies (GWAS) and Linkage Mapping Identifies Genomic Regions Associated with Seedling Root System Architecture (RSA) under Different Nitrogen Conditions in Wheat (Triticum aestivum L.)

Agriculture
The nitrogen (N) use efficiency (NUE) in the roots of seedlings is beneficial for increasing crop yield. Creating marker-assisted selection for wheat root traits can assist wheat breeders in choosing robust roots to maximize nutrient uptake. Exploring and identifying the effect of different N supply conditions on root system architecture (RSA) is of ...

Genetic dissection of the root system architecture QTLome and its relationship with early shoot development, breeding and adaptation in durum wheat [PDF]

The Plant Genome
Root system architecture (RSA), shoot architecture, and shoot‐to‐root biomass allocation are critical for optimizing crop water and nutrient capture and ultimately grain yield.
