The transfer of agronomically useful genes from wild wheat species into cultivated wheat is one of the most effective approaches to improvement of wheat varieties. To evaluate the transfer of genes from Dasypyrum villosum into Triticum aestivum, wheat quality and disease resistance was evaluated in two new translocation lines, T1DL•1V#3S and T1DS•1V#3L. We examined the levels of stripe rust resistance and dough quality in the two lines, and identified and located the stripe rust resistant genes and high molecular weight glutenin subunit (HMW-GS) genes Glu-V1 of D. villosum. Compared to the Chinese Spring (CS) variety, T1DL•1V#3S plants showed moderate resistance to moderate susceptibility to the stripe rust races CYR33 and Su11-4.

    A REVISION OF TRISETUM Victor L. Finot,' Paul M. Peterson,3 (POACEAE: POOIDEAE: Fernando 0 Zuloaga,* Robert J. v sorene, and Oscar Mattnei AVENINAE) IN SOUTH AMERICA1 ABSTRACT A taxonomic treatment of Trisetum Pers. for South America, is given. Eighteen species and six varieties of Trisetum are recognized in South America. Chile (14 species, 3 varieties) and Argentina (12 species, 5 varieties) have the greatest number of taxa in the genus. Two varieties, T. barbinode var. sclerophyllum and T longiglume var. glabratum, are endemic to Argentina, whereas T. mattheii and T nancaguense are known only from Chile. Trisetum andinum is endemic to Ecuador, T. macbridei is endemic to Peru, and T. foliosum is endemic to Venezuela. A total of four species are found in Ecuador and Peru, and there are two species in Venezuela and Colombia. The following new species are described and illustrated: Trisetum mattheii Finot and T nancaguense Finot, from Chile, and T pyramidatum Louis- Marie ex Finot, from Chile and Argentina. The following two new combinations are made: T barbinode var. sclerophyllum (Hack, ex Stuck.) Finot and T. spicatum var. cumingii (Nees ex Steud.) Finot. A key for distinguishing the species and varieties of Trisetum in South America is given. The names Koeleria cumingii Nees ex Steud., Trisetum sect. Anaulacoa Louis-Marie, Trisetum sect. Aulacoa Louis-Marie, Trisetum subg. Heterolytrum Louis-Marie, Trisetum subg. Isolytrum Louis-Marie, Trisetum subsect. Koeleriformia Louis-Marie, Trisetum subsect. Sphenopholidea Louis-Marie, Trisetum ma- lacophyllum Steud., Trisetum variabile E. Desv., and Trisetum variabile var. virescens E. Desv. are lectotypified. Key words: Aveninae, Gramineae, Poaceae, Pooideae, Trisetum.

These authors contributed equally to this work. y Received: 30 October 2019; Accepted: 31 December 2019; Published: 3 January 2020 Abstract: Powdery mildew caused by Blumeria graminis f. sp. tritici (Bgt) is one of many severe diseases that threaten bread wheat (Triticum aestivum L.) yield and quality worldwide. The discovery and deployment of powdery mildew resistance genes (Pm) can prevent this disease epidemic in wheat. In a previous study, we transferred the powdery mildew resistance gene Pm57 from Aegilops searsii into common wheat and cytogenetically mapped the gene in a chromosome region with the fraction length (FL) 0.75–0.87, which represents 12% segment of the long arm of chromosome 2Ss#1.

  • CBD First National Report
    30 PART 1.: AN OVERVIEW OF THE STATE OF BIOLOGICAL AND LANDSCAPE DIVERSITY IN CROATIA Threats to biological communities in the Adriatic Anthropogenic impacts pose a constant threat to living communities in shallow coastline areas. This primarily refers to building works carried out on the coast, to backfilling and consequential mudding of some parts of the sea, to solid waste disposal and particularly to pollution by unpurified waste waters of municipal and industrial origin. These factors pose threat to living communities of supralittoral and mediolittoral zones, and especially meadows of sea flowers Posidonia oceanica and Zostera marina (Box 27) belonging to communities of the infralittoral zone. A highly intensive process of filling up the coastal sea with diverse building and earthworks wastes is adversely affecting the settlements of various algae of genus Cystoseria, including the settlements of the endemic brown alga Adriatic wrack (Fig. 46) that has almost completely disappeared from some polluted parts of the Adriatic (western coast of Istria, Split, etc.). The degradation of ecological balance of benthonic ecosystems is also a result of excessive fishing for economic and sport reasons, including the ravaging of individual divers. In the shallow sea man particularly threatens the complex communities of photophilous algae and meadows of Posidonia oceanica, while in the depths of the sea the communities of the detrital bottom are most threatened due to consequences of natural stress conditions, and the communities of the muddy bottom due to excessive trawling. The immigration (or introduction) of the tropical green algae Caulerpa in the northern Mediterranean in 1984 represents another threat to biological diversity of the Figure 48.

NHESP is responsible for the conservation and protection of hundreds of species that are not hunted, fished, trapped, or commercially harvested in the state. The Program's highest priority is protecting the 176 species of vertebrate and invertebrate animals and 259 species of native plants that are officially listed as Endangered, Threatened or of Special Concern in Massachusetts. Endangered species conservation in Massachusetts depends on you! A major source of funding for the protection of rare and endangered species comes from voluntary donations on state income tax forms.

D. Hook.) Baillon had been made in 1893, earlier than the combination made by G. C. Druce re­ ported in our revision of the genus Amphibromus in Australia (Jacobs and Lapinpuro 1986). Baillon's combination had been overlooked by Index Kewensis and by the Chase Index (Chase and Niles 1962). The full citation is: Amphibromus nervosus (J. D. Hook.) Baillon, Histoire des Plantes 12: 203 (1893). BASIONYM: Danthonia nervosa J. D. Hook., Fl.FI. Tasm. 2: 121, pI.pl. 163A (1858). Hooker based his combination on the illegitimate Avena nervosa R. Br. (see Jacobs and Lapinpuro 1986 for further comment). Amphibromus nervosus (1. D. Hook.) G. C. Druce then becomes a superfluous combina­ tion and is added to the synonymy. Arthur Chapman also kindly pointed out a synonym that to the best of my knowledge has not been used beyond its initial publication. This synonym is: Avenastrum nervosum Vierh., Verhandlungen der Gesellschaft Deutscher Naturforscher und Artze 85. Versammlung zu Wien (Leipzig) 1: 672 (1913).

Pearsall AUGUST 2006 Dedicated to the memory of my grandmother Joanne Marie Higgins 1940-2005 ACKNOWLEDGEMENTS There are a great number of people who have helped in this process in passing or in long, detailed conversations, and everything in between. First and foremost, many thanks to my advisor, Debby Pearsall, for creative and inspired guidance, and for taking the time to talk over everything from the smallest detail to the biggest challenges. Debby introduced me to the world of phytoliths, and then to the wonders of starch grains, and encouraged me to find and pursue the issues that drive me. My committee has been very helpful and patient, and made my oral exams and defense far more enjoyable then expected—Dr. Christine Hastorf, Dr. Bob Benfer, and Dr. Randy Miles. Dr. Benfer was crucial in helping me sort through the statistical applications. I also benefited tremendously from conversations with and advice from my cohorts in the MU Paleoethnobotany lab, or as we are better known, the “Pearsall Youth”— Neil Duncan, Shawn Collins, Meghann O’Brien, Tom Hart, and Nicole Little. Dr. Karol Chandler-Ezell gave me great advice on calcium oxalate and chemical processing. Dr. Todd VanPool graciously provided much needed advice on the statistical applications.

Danthonia popinensis is a recently discovered, nationally endangered tussock grass, originally known from only one roadside population at Kempton, Tasmania. Six populations have been recorded, all from flat land with mildly acid non-rocky soils, and all in small toadside or paddock remnants, badly invaded by exotic plants. However, one site has recently been destroyed through roadworks. The species germinates best at temperatures of 10°e, indicating a winter germination strategy. Autumn burning at Kempton resulted in an increased cover of D. popinensis two years after the burn, but also resulted in an increased cover of competitive exotics. The future of the species needs to be secured by ex situ plantings, as almost all of its original habitat has been converted to crops or improved pasture.
