REGULATION OF GROWTH AND GRAVITROPISM IN THE PEANUT GYNOPHORE
… of plant growth regulators in cell growth and gravitropism of the peanut gynophore. Gibberellin and auxin were found to be important in regulating growth and gravitropism of gynophores in situ. Endogenous auxin levels appeared to be sub-optimal as low concentrations of applied IAA caused them …

Induction, Selection, and Characterization of Ethylene -Insensitive Mutants in Antirrhinum Majus (Snapdragon)
… included characteristics of rooting, gravitropism, ethylene tolerance, and vase-life studies using putative ethylene mutants. Ethylene mutants displayed varied responses for all evaluations, with some lines exhibiting enhanced rooting, gravitropism, floral fitness, ethylene tolerance, …

Molecular characterization of signaling mechanisms in flowering transition in Arabidopsis and identification of novel flowering QTL in soybean
… and TIL3/5PTase13 was established through root gravitropism experiments, and supported through flowering time experiments where til3-1/5ptase13-1 mutants were shown to reduce the late-flowering effect of TFL1 over-expression. Furthermore, in vivo sub-cellular localization in Nicotiana …

Recombinant Chromosome Substitution Lines as a Source of Genetic Variation for Drought Stress Tolerance in Barley
… seminal root elongation rate, root diameter and gravitropism that could potentially determine differences in soil water and nutrient acquisition from early stages of development in restrictive environments.<br/><br/>This study has highlighted the role of exotic germplasm to contribute novel …

Araucaria in the Urban Landscape: A Novel Leaning Pattern and Evidence of Cultivated Hybridization
… et al. 2013) and against gravity (negative gravitropism; Knight 1806, Hashiguchi et al. 2013). We also know that plants respond to mechanical stimulus and perturbation (thigmotropism; Braam 2005). Genes and their resulting proteins have been described to uncover some of the mechanisms for …

Transport phenomena in plant-internal processes: growth and carbon dioxide transport
… as becomes clear particularly in tropisms (e.g. gravitropism, hydrotropisms and phototropism). Although these processes are known for a long time in biology, no suitable measures to characterize the production of curvature and torsion have been defined. Using a curvature and torsion conservation …

Molecular characterization of signaling mechanisms in flowering transition in arabidopsis and association mapping of temperature response in floral development within glycine soja
… revealed to have increased sensitivity to root gravitropism similar to 5PTase13. While 5ptase single and double mutants do not exhibit a flowering phenotype, mutations in 5ptase13-1 and its homologs 5ptase14-1 and 5ptase12-1 significantly reduce the late flowering phenotype of overexpressed …

Einfluss von Gibberellin auf den Gravitropismus der Wurzel durch Regulation der PIN-Stabilität
… auxinrelevante Prozesse untersucht werden. Der Gravitropismus ist ein ideales System, um dynamische, auxinabhängige Prozesse wie Auxinverteilung und PIN-Endomembranfluss in der Wurzel darzustellen. Um den GA-Gehalt oder die GA-Signaltransduktion in Pflanzen gezielt zu verändern wurden …
