GENETIC MANIPULATION OF STORAGE ROOT DEVELOPMENT IN HORTICULTURAL CROPS
… vascular cambial rings of the sugar beet storage root. This gene is of interest for two reasons. As a plant-specific regulatory protein, it could play an important role in plant development. In addition, the Bvcrkl promoter could be used to regulate transgene expression m order to, for example, …

Plant root development and hormone signalling during drought stress
The plant root system is crucial for plant survival, growth and development, and it plays an important role in plant resistance to drought stress. Drought is one of the primary factors that restrict plant growth and yield, and its threat to crop yields will increase along with the growing food …

Genomic approaches to understand sweetpotato root development in relation to abiotic factors
Storage root development is the most important physiological process in sweetpotato. Understanding the underlying genetics is the overall objective of this research. A secondary objective is examining the impact of abiotic stress on gene expression and storage root development. A comprehensive …

Exploring the role of auxin in phenotypic plasticity in Arabidopsis thaliana root development
… the initiation and emergence of lateral roots. In this study we used several approaches to reduce auxin transport moving either from the shoot toward the root apex or from the root tip toward the base and examined the effect of these treatments on lateral root initiation and emergence. …

KINETIC ANALYSIS OF AUXIN-INDUCED TRANSCRIPTION FACTOR NETWORKS CONTROLLING LATERAL ROOT DEVELOPMENT IN ARABIDOPSIS THALIANA
Auxin is a phytohormone that regulates lateral root development through complex transcriptional networks. An 8-timepoint microarray of roots treated with indole-3-acetic acid (IAA), the major form of auxin, was utilized to identify the transcriptome wide kinetics of auxin response. This microarray …

Examination of auxin transport and root development in the scd1-1 mutant in Arabidopsis thaliana
… transport proteins to the appropriate membranes. Roots of scd1-1 exhibit wild-type root development at the permissive temperature, but at the nonpermissive temper are shorter than wild-type and form almost no lateral roots, but root development is reversible by IAA treatment. Acropetal IAA …

NMR AS A TOOL TO QUANTITATIVELY CHARACTERIZE MOLECULAR MECHANISMS GOVERNING ACTIN DYNAMICS AND RICE LATERAL ROOT DEVELOPMENT
… on the prolyl isomerase enzyme LRT2 (lateral rootless2) acting on the repressor protein OsIAA11. This interaction is critical for lateral root initiation in rice. The mechanism of action for this process is through the regulation of the cis-trans isomerization of the well conserved …

Identification, isolation, expression analysis and molecular characterization of nine genes key to late embryogenesis in Loblolly pine
… demonstrated to be required for late embryonic development in the model plant system Arabidopsis thaliana. These genes were subsequently isolated and cloned from Loblolly pine embryos. These isolated clones were sequenced and analyzed to reveal significant homology to the known Arabidopsis ABA …

Tissue-Specific Influence on Developmental Modulation in Response to Phosphate Deprivation in Arabidopsis thaliana Roots
<p>Roots are developmentally plastic and highly dependent on the immediate environment. By studying root responses to abiotic stress, we have identified novel regulators of developmental modulation. When roots are deprived of phosphate (Pi), developmental programs are modulated to slow primary root …

Molecular and physiological characterisation of selected DOF transcription factors in the model plant Arabidopsis thaliana
… of their specific expression pattern in the root tip, a region that comprises the stem cell niche and cells for the perception of environmental stimuli. DOF1.2, DOF3.1 and DOF3.5 are previously uncharacterized members of the Arabidopsis DOF-family, while DOF5.2 has been shown to be involved …

Studies of E2s Related to Unconventional Ubiquitination in Arabidopsis thaliana
… ubc13 mutant plants display strong phenotypes in root development. In this study, a family of six E3s that can interact with UBC13 were identified, and when a subgroup of three genes were inactivated, the T-DNA mutants showed a glucose-sensitive phenotype suggesting their possible role in sugar …
