Uncovering the genes responsible for different types of roots will transform aspects of plant agriculture.
Brace root phenotypes predict root lodging susceptibility and the contribution to anchorage in maize
TLDR
This study reports variable root lodging and plant biomechanics in a population of 52 maize inbred lines to define the important brace root phenotypes that predict root lodging resistance and demonstrate the need to uncouple the linkage between plant height and root traits for the development of climate resilient crops.
Multiple brace root phenotypes promote anchorage and limit root lodging in maize
TLDR
This study quantifies the contribution of brace roots to anchorage, brace root traits, plant height, and root lodging susceptibility in 52 maize inbred lines and shows that the contributions can be explained by plant architectural variation.
Maize brace root biomechanics are determined by geometry within a genotype and material properties between genotypes
TLDR
3-point bending tests were used to determine that brace roots from the lowest whorl have the highest structural mechanical properties regardless of growth stage, and that differences between genotypes are largely due to brace root geometry within a genotype.

Maize brace roots provide stalk anchorage
TLDR
It is demonstrated that brace roots provide a rigid base in maize and that the contribution of brace roots to anchorage was not linearly related to flowering time.
QTL identification in backcross population for brace-root-related traits in maize
TLDR
The brace-root is a crucial part of the whole root system in maize and plays an important role in the maintenance of lodging resistance, and a BC 2 F 1 population with three replicates, derived from the cross between Yi17 and Yi16 was used for quantitative trait locus (QTL) detection.
The Crosstalk between MicroRNAs and Gibberellin Signalling in Plants.
TLDR
Recent advances in the understanding of the molecular connections between miRNAs and GA are reviewed, with an emphasis on the twomiRNAs, miR156 and miR159.
Ectopic expression of ARGOS8 reveals a role for ethylene in root‐lodging resistance in maize
Summary Ethylene plays a critical role in many diverse processes in plant development. Recent studies have demonstrated that overexpression of the maize ARGOS8 gene reduces the plant's response to
Mapping QTLs and Identification of Genes Associated with Drought Resistance in Sorghum.
TLDR
The loci, quantitative trait loci (QTLs), or genes that have been identified for traits involved in drought avoidance (water-use efficiency, cuticular wax synthesis, trichome development and morphology, root system architecture) and drought tolerance (compatible solutes, pre- and post-flowering drought tolerance) are described.
Over-expression of the photoperiod response regulator ZmCCT10 modifies plant architecture, flowering time and inflorescence morphology in maize
TLDR
Results from this study clarified the influence of the photoperiod pathway on vegetative and reproductive development and allowed for the fine-tuning of the maize flowering time model.
ZmRAP2.7, an AP2 Transcription Factor, Is Involved in Maize Brace Roots Development
TLDR
A function of ZmRAP2.7 in brace roots development was uncovered and provided the valuable gene and allele for genetic improvement of maize root systems.
Distinct gene networks modulate floral induction of autonomous maize and photoperiod-dependent teosinte
Comparison of day-neutral temperate maize and photoperiod-dependent teosinte revealed divergent leaf gene expression networks that implicate different genes of the same gene families in response to
