Email: [email protected] Abstract. Leptosphaeria biglobosa ‘canadensis’ is reported for the first time in Australia. All 88 Leptosphaeria isolates cultured from Brassica juncea stubble from northern NSW were L. biglobosa ‘canadensis’ whilst all 55 isolates cultured from Victorian stubble of the same B. juncea lines were L. maculans. Both L. biglobosa ‘canadensis’ and L. maculans formed similar sized lesions on B. juncea cotyledons after 14 days. However, L. biglobosa ‘canadensis’ isolates colonised stems less effectively than L. maculans and consequently caused less crown cankering. The two Dothideomycetes, Leptosphaeria maculans and B. juncea is more drought-tolerant and can be grown in regions L. biglobosa, comprise a species complex associated with with short, warm to hot growing seasons in which soil water disease of crucifers including Brassica napus (canola, oilseed supply is unreliable (Oram et al. 2005). In Canada, B. juncea has rape). Through the use of molecular techniques, L. biglobosa has been grown as a condiment mustard crop for 20 years, specifically been divided into six subclades, namely ‘canadensis’, in the hotter, drier areas of western Canada. -

New evidence inferred from phylogenetic analyses of nuclear ribosomal DNA sequence data together with abroad taxon sampling at family level suggest that the fungus is amember of Extremaceaeand therefore its previous placement within the broadly defined Teratosphaeriaceae was not supported. Anew genus Castanedospora is introduced to accommodate this species on the basis of its distinct morphology and phylogenetic position distant from Sporidesmiaceae sensu stricto in Sordariomycetes. The holotype material from Cuba was found to be exhausted and the Florida specimen, which agrees well with the original description, is selected as epitype. The fungus produced considerably long cylindrical to narrowly obclavate conidia -

Warm and Wet Autumns Favour Yield Losses of Oilseed Rape Caused by Phoma Stem Canker
agronomy Article Warm and Wet Autumns Favour Yield Losses of Oilseed Rape Caused by Phoma Stem Canker Andrzej Brachaczek 1 , Joanna Kaczmarek 2 and Malgorzata Jedryczka 2,* 1 Corteva Agriscience Poland Ltd., Józefa Piusa Dzieko´nskiego1, 00-728 Warsaw, Poland; [email protected] 2 Department of Pathogen Genetics and Plant Resistance, Institute of Plant Genetics, Polish Academy of Sciences, Strzeszynska 34, 60-479 Pozna´n,Poland; [email protected] * Correspondence: [email protected]; Tel.: +48-616-550-271 Abstract: Winter oilseed rape (Brassica napus L.) is the main source of domestic oil in central and northern Europe, bringing profits to farmers, but the plants are often damaged by stem canker, caused by two fungal species belonging to the genus Leptosphaeria. Due to environmental concerns, the benefits of fungicide applications must outweigh disadvantages. The aim of this work was to determine the effect of stem canker on seed yield and its quality and find out the best timing of fungicide application. The multi-year field experiments were done at two sites in south-west Poland, where the disease is regarded as a serious problem. The fungicide treatments with the azole-containing preparation followed the same scheme each year; a single application was made at one-week intervals, starting in late September through mid-November for a total of eight treatments. Seed yield, oil and protein content, mass of thousand seeds as well as indole-and alkenyl-glucosinolate contents in seeds were statistically unrelated with the incidence and severity of phoma leaf spotting and stem canker symptoms. The significant decrease of the seed yield was observed in three Citation: Brachaczek, A.; Kaczmarek, (site × year combinations) of eight, in which phoma leaf spotting and stem canker were severe. -

ABSTRACT Pyrenophora teres f. teres, the causal agent of net form net blotch (NFNB) of barley, is a KEYWORDS destructive pathogen in barley-growing regions throughout the world. Typical yield losses due to NFNB Pyrenophora range from 10 to 40%; however, complete loss has been observed on highly susceptible barley lines where teres f. teres environmental conditions favor the pathogen. Currently, genomic resources for this economically important genome pathogen are limited to a fragmented draft genome assembly and annotation, with limited RNA support of sequencing the P. teres f. teres isolate 0-1. This research presents an updated 0-1 reference assembly facilitated by RNAseq long-read sequencing and scaffolding with the assistance of genetic linkage maps. Additionally, genome PacBio annotation was mediated by RNAseq analysis using three infection time points and a pure culture sample, barley resulting in 11,541 high-confidence gene models. The 0-1 genome assembly and annotation presented genome report here now contains the majority of the repetitive content of the genome. Analysis of the 0-1 genome revealed classic characteristics of a “two-speed” genome, being compartmentalized into GC-equilibrated and AT-rich compartments. -

Most of the fungi sequenced were intertidal mangrove taxa and belong to members of 12 families in the Pleosporales: Aigialaceae, Didymellaceae, Leptosphaeriaceae, Lenthitheciaceae, Lophiostomataceae, Massarinaceae, Montagnulaceae, Morosphaeriaceae, Phaeosphaeriaceae, Pleosporaceae, Testudinaceae and Trematosphaeriaceae.

Ces. & De Not., which causes blackleg disease. This fungus produces strains with different virulence profiles (pathogenicity groups, PG) which are defined using differential cultivars Westar, Quinta and Glacier. Besides this, little is known about other traits that characterize these groups. The objective of this study was to characterize the aggressiveness of L. maculans PG 2, 3, 4, and T. The components of aggressiveness evaluated were disease severity and ability to grow and sporulate in artificial medium. Disease severity was measured at different temperatures on seedlings of cv. Westar inoculated with pycnidiospores of 65 isolates. Highly significant (α=0.05) interactions were detected between colony age and isolates nested within PG’s.
