Journal ArticleDOI
A Putative ABC Transporter Confers Durable Resistance to Multiple Fungal Pathogens in Wheat
Simon G. Krattinger,Evans Lagudah,Wolfgang Spielmeyer,Ravi P. Singh,Julio Huerta-Espino,Helen G. McFadden,Eligio Bossolini,Liselotte L. Selter,Beat Keller +8 more
TL;DR: It is shown that the LR34 protein resembles adenosine triphosphate–binding cassette transporters of the pleiotropic drug resistance subfamily, which functions in the adult plant and stimulates senescence-like processes in the flag leaf tips and edges.
Journal ArticleDOI
Semidwarf (sd-1), "green revolution" rice, contains a defective gibberellin 20-oxidase gene
TL;DR: The semidwarf phenotype is the result of a deficiency of active GAs in the elongating stem arising from a defective 20-oxidase GA biosynthetic enzyme, and it is proposed that the Os20ox2 gene corresponds to the sd-1 locus.
Journal ArticleDOI
"Perfect" markers for the Rht-B1b and Rht-D1b dwarfing genes in wheat.
TL;DR: PCR-based markers developed to detect the point mutations responsible for the two major semi-dwarfing genes Rht-B1b and Rht -D1b in wheat will have utility in marker-assisted selection of these genes in wheat breeding programs.
Journal ArticleDOI
A recently evolved hexose transporter variant confers resistance to multiple pathogens in wheat.
John W. Moore,S. A. Herrera-Foessel,Caixia Lan,Wendelin Schnippenkoetter,Michael Ayliffe,Julio Huerta-Espino,Morten Lillemo,Libby Viccars,Ricky J. Milne,Sambasivam Periyannan,Xiuying Kong,Wolfgang Spielmeyer,Mark J. Talbot,Harbans Bariana,John W. Patrick,Peter N. Dodds,Ravi P. Singh,Evans Lagudah +17 more
TL;DR: The wheat Lr67 gene is isolated, which confers partial resistance to all three wheat rust pathogen species and powdery mildew, and exerts a dominant-negative effect through heterodimerization with these functional transporters to reduce glucose uptake.
Journal ArticleDOI
A Physical Map of the 1-Gigabase Bread Wheat Chromosome 3B
Etienne Paux,Pierre Sourdille,Jérôme Salse,Cyrille Saintenac,Frédéric Choulet,Philippe Leroy,Abraham B. Korol,Monika Michalak,Shahryar F.

TL;DR: A bacterial artificial chromosome (BAC)–based integrated physical map of the largest chromosome, 3B, that alone is 995 megabases is constructed, establishing a template for the remaining wheat chromosomes and demonstrating the feasibility of constructing physical maps in large, complex, polyploid genomes with a chromosome-based approach.
