MutS Homolog 1 (MSH1) encodes a plant-specific protein that functions in mitochondria and chloroplasts. We showed previously that disruption or suppression of the MSH1 gene results in a process of developmental reprogramming that is heritable and non-genetic in subsequent generations. In Arabidopsis, this developmental reprogramming process is accompanied by striking changes in gene expression of organellar and stress response genes. This developmentally reprogrammed state, when used in crossing, results in a range of variation for plant growth potential. Here we investigate the implications of MSH1 modulation in a crop species. We found that MSH1-mediated phenotypic variation in Sorghum bicolor …

Effects Of Culture Media And Plant Growth Regulators On Micropropagation Of Willow (Salix Matsudana ‘Golden Spiral’) And Hazelnut (Corylus Colurna ‘Te Terra Red), Dongxue Shi

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

The branches and leaves of Salix matsudana ‘Golden Spiral’ , willow, grow in a twisted manner, which makes it an important bonsai plant. Its mature stems have potential for the woody cut floral industry. Corylus colurna ‘ Te Terra Red’, hazelnut, distinguished by red or purple leaves in the spring, has potential ornamental value in the horticulture industry for landscape use. Micropropagation of these two plants could provide more and healthier plantlets for rapid commercial scale-up by the nursery industry. Nas and Read Medium (NRM) is a newer medium developed specifically for hazelnut species by Nas and Read based on …

The sorghum [Sorghum bicolor (L.) Moench] cultivar CI0947bmr (Reg. No. CV-137, PI 672153) was jointly developed and released by the Centro Nacional de Tecnología Agropecuaria y Forestal (CENTA) research program in El Salvador and the Texas A&M Agrilife Research sorghum breeding program in 2013. CI0947bmr is a brown midrib (bmr), dual-purpose sorghum selected for productivity in Central American environments. CI0947bmr was developed from a pedigree breeding program, and it was derived from a BC₁F₂ population of the pedigree B03292bmr/Tortillero//Tortillero. All generation advancement and selection were completed in San Andres, El Salvador. To confirm performance …

Functional Genomics Of Maize Endosperm Maturation And Protein Quality, Lingling Yuan

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Maize is one of the most important cereal crops and widely cultivated throughout the world. The study on maize kernel development including protein quality improvement is essential for removing dietary protein deficiency because of the lack of essential amino acids, especially lysine and tryptophan, in maize kernel. Quality Protein Maize (QPM) is a hard kernel variant of the high-lysine mutant, opaque-2. We created opaque QPM variants to identify opaque-2 modifier genes and to investigate deletion mutagenesis combined with Illumina sequencing as a maize functional genomics tool. A K0326Y-QPM deletion mutant, line 107, was null for the 27- and 50-kD …
