Mapping Resistance to Stem Rust, Stripe Rust, and Powdery Mildew, and Genotype Screening of Breeding Germplasm for Disease Resistance
ABSTRACT VANGESSEL, CARL JOSEPH. Disease Resistance in Winter Wheat: Mapping Resistance to Stem Rust, Stripe Rust, and Powdery Mildew, and Genotype Screening of Breeding Germplasm for Disease Resistance. (Under the direction of Dr. David Marshall). Wheat production worldwide faces many challenges including fungal pathogens which can reduce growth, nutrient content, and yield. As the global population continues to increase, it is important to maximize production of wheat which provides a significant proportion of the human diet. Wheat breeders and pathologists are addressing the pathogen threat to wheat by breeding cultivars with improved resistance. However, as pathogen populations mutate and overcome resistance, it is important to identify sources of resistance to new pathogen races and understand the genetics of resistance in commercial cultivars. Stem rust (Puccinia graminis), stripe rust (Puccinia striiformis), and powdery mildew (Blumeria graminis) are among the most common and aggressive pathogens of wheat occurring worldwide. The stem rust resistance gene Sr31 was reliably effective until being overcome in 1999 by the race Ug99. This new race of stem rust has since evolved to include 12 related races and are potentially virulent to a majority of commercially produced wheat globally. The soft red winter wheat (SRWW) line, MD01W28- 08-11, was identified as having adult plant resistance (APR) to Ug99 in Njoro, Kenya. This line was crossed with the susceptible SRWW cultivar Coker 9553 and the subsequent 279 doubled haploid (DH) population used for linkage mapping analysis to better characterize the source of stem rust APR. A linkage map with 3,159 SNPs was produced that identified a significant quantitative trait loci (QTL) on the short arm of chromosome 6D and two QTL on the long arms of chromosomes 2B and 4B. -

NSC-631570 (Ukrain) is an aqueous extract of laminin). Microarray analysis revealed the downregulation of Chelidonium majus, a herbaceous perennial plant, one of two genes encoding key regulators, including EGFR, AKT2, JAK1, species in the genus Chelidonium, which has been demonstrated STAT3 and ß-catenin (CTNNB1), all of which are involved in to selectively kill tumor cells without affecting non-malignant cell proliferation, migration, angiogenesis, apoptosis as well as cells. In the present study, the components of NSC-631570 the radiation- and chemo-resistance of HNSCC. The strongest were examined by combined liquid chromatography/mass upregulation occurred for cytochrome P450 1A1 (CYP1A1) spectroscopy (LC-MS) and the effects of NSC-631570 on and 1B1 (CYP1B1), involved in the metabolism of xenobiotics.

LC-MS identified chelerythrine and HNSCC cell lines. In addition, NSC-631570 showed a high allocryptopine as the major alkaloids of the extract. -
1. Introduction
Introduction 1. Introduction 1.1. Alkaloids The term alkaloid is derived from Arabic word al-qali, the plant from which “soda” was first obtained (Kutchan, 1995). Alkaloids are a group of naturally occurring low-molecular weight nitrogenous compounds found in about 20% of plant species. The majority of alkaloids in plants are derived from the amino acids tyrosine, tryptophan and phenylalanine. They are often basic and contain nitrogen in a heterocyclic ring. The classification of alkaloids is based on their carbon-nitrogen skeletons; common alkaloid ring structures include the pyridines, pyrroles, indoles, pyrrolidines, isoquinolines and piperidines (Petterson et al., 1991; Bennett et al., 1994). In nature, plant alkaloids are mainly involved in plant defense against herbivores and pathogens. Many of these compounds have biological activity which makes them suitable for use as stimulants (nicotine, caffeine), pharmaceuticals (vinblastine), narcotics (cocaine, morphine) and poisons (tubocurarine). The discovery of morphine by the German pharmacist Friedrich W. Sertürner in 1806 began the field of plant alkaloid biochemistry. However, the structure of morphine was not determined until 1952 due to its stereochemical complexity. Major technical advances occurred in this field allowing for the elucidation of selected alkaloid biosynthetic pathways. Among these were the introduction of radiolabeled precursors in the 1950s and the establishment in the 1970s of plant cell suspension cultures as an abundant source of enzymes that could be isolated, purified and characterized. Finally, the introduction of molecular techniques has made possible the isolation of genes involved in alkaloid secondary pathways (Croteau et al., 2000; Facchini, 2001). 1.1.1. Benzylisoquinoline alkaloids Isoquinoline alkaloids represent a large and varied group of physiologically active natural products. -

E-mail: [email protected]. Accepted 6th July, 2018 Abstract. Stem rust caused by Puccinia graminis f. sp. tritici (Pgt) is one of the most important diseases of wheat in Ethiopia. The stem rust pathogen is capable to rapidly develop new virulence to resistance genes owing to mutation and genetic recombination. Ethiopian highlands are known hot spots for the rapid evolution and spread of new rust races. The present study was conducted to investigate the virulence diversity and spatial distribution of races of Pgt in the major wheat growing areas of Ethiopia. The physiologic races of the rust fungus were determined on seedlings of the standard wheat stem rust differentials following the international system of nomenclature. Three hundred and forty- seven samples were analyzed in 2014 and 2015 cropping seasons from Oromia, Amhara, Tigray and Southern Nations and Nationalities Peoples’ regions. -

Species Accounts
Species accounts The list of species that follows is a synthesis of all the botanical knowledge currently available on the Nyika Plateau flora. It does not claim to be the final word in taxonomic opinion for every plant group, but will provide a sound basis for future work by botanists, phytogeographers, and reserve managers. It should also serve as a comprehensive plant guide for interested visitors to the two Nyika National Parks. By far the largest body of information was obtained from the following nine publications: • Flora zambesiaca (current ed. G. Pope, 1960 to present) • Flora of Tropical East Africa (current ed. H. Beentje, 1952 to present) • Plants collected by the Vernay Nyasaland Expedition of 1946 (Brenan & collaborators 1953, 1954) • Wye College 1972 Malawi Project Final Report (Brummitt 1973) • Resource inventory and management plan for the Nyika National Park (Mill 1979) • The forest vegetation of the Nyika Plateau: ecological and phenological studies (Dowsett-Lemaire 1985) • Biosearch Nyika Expedition 1997 report (Patel 1999) • Biosearch Nyika Expedition 2001 report (Patel & Overton 2002) • Evergreen forest flora of Malawi (White, Dowsett-Lemaire & Chapman 2001) We also consulted numerous papers dealing with specific families or genera and, finally, included the collections made during the SABONET Nyika Expedition. In addition, botanists from K and PRE provided valuable input in particular plant groups. Much of the descriptive material is taken directly from one or more of the works listed above, including information regarding habitat and distribution. A single illustration accompanies each genus; two illustrations are sometimes included in large genera with a wide morphological variance (for example, Lobelia). -

Meiotic studies have been carried out for analyzing the genetic diversity in 11 populations covering four species from different selected parts of the Western Himalayas, such as Kashmir (Jammu and Kashmir) and the districts of Kangra and Sirmaur (Himachal Pradesh). The species being cytologically worked out for the first time worldwide include B. ceratophylla (2n = 28). Similarly, B. vulgaris (2n = 28), although worked out earlier from other countries, is being reported cytologically for the first time from India. The meiotic course in most of these populations has been observed to be normal except for a single population each of B. asiatica, B. ceratophylla and B. vulgaris marked with abnormal meiosis. Out of these three species, two (B. asiatica and B. vulgaris) are marked with cytomixis. These meiotic abnormalities lead to the production of heterogenous-sized fertile pollen grains and reduced pollen fertility. Key words Berberis, Chromosome number, Meiotic abnormality, Western Himalayas. Berberis is popularly known as barberry and is the largest genus of the family containing about 500 species native to the temperate and subtropical regions of Europe, Asia, Africa, and North and South America (Ahrendt 1961). -
