Genetic Control of Root System Architecture in Rice
… has largely focused on aboveground phenotypes, root system traits represent potential unexplored targets for stress resilience and yield improvement. However, our understanding of the genetic control of root system architecture (RSA) in rice is fundamentally insufficient to contribute to these …

STUDY OF LOCAL ENVIRONMENTAL CONTROL OF ROOT SYSTEM ARCHITECTURE
… environment in nature, especially the root system. In a relatively small volume, soils vary greatly in texture, nutrient contents, pH, and moisture content, all of which has a great impact on shaping root architecture. Work presented in this thesis reveals that under normal growth …

Combining genotyping-by-sequencing data sets for GWAS and GWS study for maize root System architecture traits
Maize has a sophisticated and complex root architecture that is important for plant anchorage and uptake of nutrients and water. Tools such as genome-wide association (GWAS) and genome-wide selection (GWS) can help the breeders to make decisions about which genotypes should advance in their …

The Evaluation of Root System Architecture (RSA) As A New Breeding Target for Climate-Resilient Winter Wheat (Tritium aestivum L.)
… for plant breeders to shift their focus to the root system architecture (RSA) as a new target for indirect selection, enabled by the phenotypic plasticity of winter wheat (Triticum sp.), one of the main staple agronomic crops. Our current limited understanding of the dynamic nature of the root …

PHENOTYPING OF GRAPEVINE ROOT SYSTEM FOR DROUGHT ADAPTATION
… strategies, the adoption of drought tolerant rootstocks has emerged as one of the most promising and sustainable approaches. Since the outbreak of Phylloxera in the 19th century grapevine has been predominantly propagated through grafting and rootstocks have become essential tools to regulate …

Novel strategies for genomic and phenomic investigations of quantitative traits in maize (Zea mays L.)
… the efficiency of plant breeding solutions. Root system architecture (RSA) plays important roles the adaptation of crops to the environments in which they are grown, but the genetic basis of RSA traits is understudied due to the difficulty of phenotyping for RSA under field conditions. To …

Three dimensional reconstruction of plant roots via low energy x-ray computed tomography
Plant roots are vital organs for water and nutrient uptake. The structure and spatial distribution of plant roots in the soil affects a plant's physiological functions such as soil-based resource acquisition, yield and its ability to live under abiotic stress. Visualizing and quantifying roots' …

Unlocking the genetic potential of the root system, rhizosheath mucilage and microbiome of wheat (Triticum aestivum L.)
… of latitudes across both hemispheres. The wheat root system is a crucial determinant of plant performance, yet roots are overlooked in breeding due to the challenge of studying organs below ground. Evidence from the literature indicate that water and nutrient uptake are often suboptimal in high …

A Lateral Root Defect in the wag1-1/wag2-1 Double Mutant of Arabidopsis
The root system architecture of higher plants plays an essential role in the uptake of water and nutrients as well as the production of hormones. These root systems are highly branched with the formation of post-embryonic organs such as lateral roots. The initiation and development of lateral roots …

SNP ANALYSIS FOR DROUGHT-RELATED CANDIDATE GENES IN A GERMPLASM COLLECTION AND A TILLING POPULATION OF ITALIAN RICE
… at understanding the genetic determinants of root system architecture in the Italian rice germplasm, considering the profound implications of root development on the ability of the plant to cope with water deficits. The first Genome-Wide Association study on root traits was then performed on a …

Evaluation of additive and nonadditive genetic variation in elite maize germplasm for root, shoot, and ear characteristics
… as grain yield, maturity, uniformity of plant architecture to accommodate mechanized farming, increased ear size, increased nitrogen use efficiency, disease resistance, stalk and root strength, as well as generally improved performance under a range of biotic and abiotic stresses. Ten …
