Indole-3-acetic acid (IAA) controls a plethora of developmental processes. Thus, regulation of its concentration is of great relevance for plant performance. Cellular IAA concentration depends on its transport, biosynthesis and the various pathways for IAA inactivation, including oxidation and conjugation.
Group II members of the GRETCHEN HAGEN 3 (GH3) gene family code for acyl acid amido synthetases catalysing the conjugation of IAA to amino acids. However, the high degree of functional redundancy among them has hampered thorough analysis of their roles in plant development.
In this work, we generated an Arabidopsis gh3.1,2,3,4,5,6,9,17 (gh3oct) mutant to knock out the group II …

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
Excessive salt is a major factor limiting crop productivity. Rice is an important food crop worldwide, and provides a major source of calories for billions of people in tropical and subtropical developing countries. In many regions throughout Southeast Asia, rice is grown in low-lying coastal regions, which are prone to ingress by seawater. Rice is highly sensitive to salt stress, with mild salinity resulting in large reductions in yield. Improving salt tolerance in rice is essential for ensuring food security for many individuals throughput the developing world.
In this work, the overall goals were to characterize a diverse collection of …
Some Factors Affecting Germination And Seedling Growth Of Scotch Thistle, C. J. Scifres, M. K. Mccarty
Some Factors Affecting Germination And Seedling Growth Of Scotch Thistle, C. J. Scifres, M. K. Mccarty
Nebraska Agricultural Experiment Station: Historical Research Bulletins
Scotch thistle (Onopordum acanthium L.) is a native of Eurasia. Scotch thistle is found in the grasslands of central Nebraska, with heaviest infestations in Gosper, Dawson, and Valley Counties and limited occurrence in 18 additional counties. The Nebraska Unicameral declared it a noxious weed in 1965. This study measures the effects of some environmental factors on scotch thistle germination and seedling growth, and clarifies some of the interactions of these with inherent characteristics of the achene. The effect of achene coat, stratification, light, temperature, growth regulators, pH, depth of planting, salinity, germination inhibitors, and moisture stress were studied.
