  • 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.

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.

  • Induced Resistance in Wheat
    https://doi.org/10.35662/unine-thesis-2819 Induced resistance in wheat A dissertation submitted to the University of Neuchâtel for the degree of Doctor in Naturel Science by Fares BELLAMECHE Thesis direction Prof. Brigitte Mauch-Mani Dr. Fabio Mascher Thesis committee Prof. Brigitte Mauch-Mani, University of Neuchâtel, Switzerland Prof. Daniel Croll, University of Neuchâtel, Switzerland Dr. Fabio Mascher, Agroscope, Changins, Switzerland Prof. Victor Flors, University of Jaume I, Castellon, Spain Defense on the 6th of March 2020 University of Neuchâtel Summary During evolution, plants have developed a variety of chemical and physical defences to protect themselves from stressors. In addition to constitutive defences, plants possess inducible mechanisms that are activated in the presence of the pathogen. Also, plants are capable of enhancing their defensive level once they are properly stimulated with non-pathogenic organisms or chemical stimuli. This phenomenon is called induced resistance (IR) and it was widely reported in studies with dicotyledonous plants. However, mechanisms governing IR in monocots are still poorly investigated. Hence, the aim of this thesis was to study the efficacy of IR to control wheat diseases such leaf rust and Septoria tritici blotch. In this thesis histological and transcriptomic analysis were conducted in order to better understand mechanisms related to IR in monocots and more specifically in wheat plants. Successful use of beneficial rhizobacteria requires their presence and activity at the appropriate level without any harmful effect to host plant. In a first step, the interaction between Pseudomonas protegens CHA0 (CHA0) and wheat was assessed. Our results demonstrated that CHA0 did not affect wheat seed germination and was able to colonize and persist on wheat roots with a beneficial effect on plant growth.

Many cultures are exposed to them. The disease is difficult to control on a large scale; thus, one of the relevant approaches is the crop field monitoring, which helps to identify the disease at an early stage and take measures to prevent its spread. One of the effective control methods is disease identification based on the analysis of digital images, with the possibility of obtaining them in field conditions, Citation: Genaev, M.A.; Skolotneva, using mobile devices.

  • Wheat Leaf Rust
    Marcia McMullen Jack Rasmussen Plant Pathologist Plant Pathologist PP589 (Revised) NDSU Extension Service Agricultural Experiment Station WHEAT LEAF RUST Wheat leaf rust, caused by the fungus Puccinia triticina (formerly recondita f. sp. tritici), reduces wheat yields in susceptible varieties when weather conditions favor rust development and spread. The most notable signs of leaf rust infection are the reddish-orange spore masses of the fungus breaking through the leaf surface (Figure 1). These spore masses, called pus- tules or uredinia, are first detected on wheat in North Dakota in late May or early June, generally in the Figure 1. Top: Resistant reaction; Center: Moderately resistant reac- southern-most counties. Normally, tion; Bottom: Susceptible reaction. only a few pustules are visible on susceptible varieties in early June because spore numbers are still low. The disease develops prior to this period on susceptible winter or spring wheat crops grown in states farther south. The leaf rust spores are carried by wind currents, and the disease advances progressively northward across the Great Plains as the wheat crops develop (Figure 2). The leaf rust pathogen has only occasionally over-wintered in North Dakota, during a mild winter or when protected by deep snow. Figure 2. Leaf rust disease cycle. North Dakota State University, Fargo, North Dakota 58105 JULY 2002 The Disease The following factors must be present for wheat leaf rust infection to occur: viable spores; susceptible or moder- ately susceptible wheat plants; moisture on the leaves (six to eight hours of dew); and favorable temperatures (60 to 80 degrees Fahrenheit). Relatively cool nights combined with warm days are excellent conditions for disease development.

It is important to realise that feeding stock with ergot infested grain can result in serious losses. Grain with three ergots per 1,000 kernels can be toxic. 1 • Stem and leaf rusts can usually be seen on cereal rye in most years, but they are only occasionally a serious problem. 2 • All commercial cereal rye varieties have resistance to the current pathotypes of stripe rust. However, the out-crossing nature of the species will mean that under high disease pressure, a proportion of the crop (approaching 15–20% of the plant population) may show evidence of the disease. Other diseases are usually insignificant. • Cereal rye has tolerance to take-all, making it a useful break crop following grassy pastures. 3 • Bevy is a host for the root disease take-all and this should be carefully monitored. 4 General disease management strategies: • Use resistant or partially resistant varieties. • Use disease-free seed. • Use fungicidal seed treatments to kill fungi carried on the seed coat or in the seed. • Have a planned in-crop fungicide regime. • Conduct in-crop disease audits to determine the severity of the disease. This can be used as a tool to determine what crop is grown in what paddock the following year.

  • 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).

  • Virulence of Puccinia Triticina on Wheat in Iran
    African Journal of Plant Science Vol. 4 (2), pp. 026-031, February 2010 Available online at http://www.academicjournals.org/ajps ISSN 1996-0824 © 2010 Academic Journals Full Length Research Paper Virulence of Puccinia triticina on wheat in Iran S. Elyasi-Gomari Azad Islamic University, Shoushtar Branch, Faculty of Agriculture, Shoushtar, Iran. E-mail: [email protected]. Accepted 12 January, 2010 Wheat leaf rust is controlled mainly by race-specific resistance. To be effective, breeding wheat for resistance to leaf rust requires knowledge of virulence diversity in local populations of the pathogen. Collections of Puccinia triticina were made from rust-infected wheat leaves on the territory of Khuzestan province (south-west) in Iran during 2008 - 2009. In 2009, up to 20 isolates each of the seven most common leaf rust races plus 8 -10 isolates of unnamed races were tested for virulence to 35 near- isogenic wheat lines with different single Lr genes for leaf rust resistance. The lines with Lr9, Lr25, Lr28 and Lr29 gene were resistant to all of the isolates. Few isolates of known races but most isolates of the new, unnamed races were virulent on Lr19. The 35 Lr gene lines were also exposed to mixed race inoculum in field plots to tests effectiveness of their resistance. No leaf rust damage occurred on Lr9, Lr25, Lr28 and Lr29 in the field, and lines with Lr19, Lr16, Lr18, Lr35, Lr36, Lr37 and the combination Lr27 + Lr31 showed less than 15% severity. A total of 500 isolates of P. triticina obtained from five commercial varieties of wheat at two locations in the eastern and northern parts of the Khuzestan region were identified to race using the eight standard leaf rust differential varieties of Johnson and Browder.
