This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Responsible for over 20% of the calories consumed by humans, wheat and barley were among the first crops domesticated by humans. These two crops made a significant contribution to the transition of humans from a nomadic to an agrarian lifestyle, allowing for the development of more complex societies. After millennia of gradual farmer based selection, the green revolution of the mid-20th century dramatically increased yields of wheat at a time when the rapid human population growth threatened global food security. These rapid gains in yield resulted from the application of an improved understanding of plant genetics and a more rigorous approach to plant breeding aimed at the development of cultivars that could utilize additional nutrient inputs. The incorporation of modern molecular genetics and genomics tools to breeding has the potential to once again accelerate current rates of improvement to achieve the grain yield levels required to feed an increasing human population. This dissertation presents examples of the use of these modern tools to develop improved barley and wheat germplasm. The first chapter describes the genetic mapping of four loci for tolerance to Cereal Yellow Dwarf Virus (CYDV) tolerance in barley, a problem that has delayed the development of malting barley varieties for California. Molecular markers for these resistance genes are particularly useful because the sporadic nature of this disease poses a challenge for traditional breeding strategies. The second chapter describes the utilization of these markers for CYDV tolerance in combination with agronomic and quality tests that support the release of the two-row malting barley variety ‘UC Tahoe’. The third chapter describes the validation of a novel stripe rust resistance locus in wheat, designated as Yr78. Using bi-parental population, this study identified 10 wheat accessions carrying Yr78 and a closely linked molecular marker that will be useful to incorporate this novel resistance gene in wheat breeding programs.

This book was released on 1995 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Barley yellow dwarf viruses (BYDVs) cause the most economically important and widespread virus disease of small grains. Breeding resistant plants has been the most effective and economical method of control. In order to understand the molecular basis for tolerance to BYDV, studies were initiated to characterize the genes involved in the tolerance. Two dimensional protein gel electrophoresis was used to determine whether there were differences in protein profiles between one sensitive (Clintland 64) and four tolerant oat cultivars (Ogle, IL86-5698, IL86-1156 and IL86-6404). Differences were observed among all tested cultivars, but no single protein was found in all tolerant cultivars that was not also found in the sensitive cultivar. Differences were observed in mRNAs from three oat cultivars (Clintland 64, IL86-5698 and Ogle using differential display of mRNA. Further analysis of recovered polymorphic bands showed no detectable differences in Southern and northern blots from the tested cultivars. Since four different tolerant cultivars were examined, it is possible that different genes were responsible for tolerance in the different tolerant cultivars. To simplify the analysis, subsequent experiments focused on one pair of sensitive (Clintland 64) and tolerant (IL86-5698) oat cultivars. Representational difference analysis (RDA) was adapted to clone the differentially expressed or polymorphic genes from mRNAs in Clintland 64 or IL86-5698. One cDNA clones, OARE (for OAt RetroElement), identified by RDA was similar to copia-like retroelements and another one, OACW (for Oat Cold or Water-like gene), was similar to cold or water stress-related genes. Neither of the clones revealed differences in genomic DNAs from Clintland 64 or IL86-5698. Both were expressed constitutively and OACW expression is at the same levels in roots and leaves. Differences were observed in the PCR products from genomic DNA using a primer designed from the OACW sequence, and Dpn II digested major PCR products. Transcription of retroelements and cold and water stress-related genes has been reported to be activated by environmental stresses. Studies have also shown that symptom development, biochemical changes and root growth after BYDV infection are similar to those induced by environmental stresses. This suggests that the functions of the two clones I have found may be related to plant responses to BYDV infection.
