Barberry plays an active role as an alternate host of Puccinia graminis in Spain
(Wiley, 2022-02-17)
Stem rust, caused by Puccinia graminis, is a destructive group of diseases. The pathogen uses Berberis species as alternate hosts to complete its life cycle. B. vulgaris and the endemic species B. ...
Plant Breeding and Management Strategies to Minimize the Impact of Water Scarcity and Biotic Stress in Cereal Crops under Mediterranean Conditions
(MDPI, 2021-12-29)
Wheat and rice are two main staple food crops that may suffer from yield losses due to drought episodes that are increasingly impacted by climate change, in addition to new epidemic outbreaks. Sustainable ...
Genetic Structure of Modern Durum Wheat Cultivars and Mediterranean Landraces Matches with Their Agronomic Performance
(Public Library of Science, 2016-08-11)
A collection of 172 durum wheat landraces from 21 Mediterranean countries and 20 modern cultivars were phenotyped in 6 environments for 14 traits including phenology, biomass, yield and yield omponents. ...
Wheat Stem Rust Back in Europe: Diversity, Prevalence and Impact on Host Resistance
(Frontiers Media, 2022-06-02)
The objective of this study was to investigate the re-emergence of a previously important crop pathogen in Europe, Puccinia graminis f.sp. tritici, causing wheat stem rust. The pathogen has been ...
Recombination in the wheat stem rust pathogen mediated by an indigenous barberry species in Spain
(Frontiers Media, 2024-01-15)
The comeback of wheat stem rust in Europe, caused by Puccinia graminis f. sp. tritici, and the prevalence of the alternate (sexual) host in local areas have recently regained attention as a potential ...
Variability in glutenin subunit composition of Mediterranean durum wheat germplasm and its relationship with gluten strength
(Cambridge University Press, 2013-01-23)
The allelic composition at five glutenin loci was assessed by one-dimensional sodium dodecyl sulphate
polyacrylamide gel electrophoresis (1D SDS–PAGE) on a set of 155 landraces (from 21 Mediterranean ...
Short communication: Emergence of a new race of leaf rust with combined virulence to Lr14a and Lr72 genes on durum wheat
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (INIA), 2016-08-31)
Leaf rust is a foliar disease caused by the fungus Puccinia triticina that may severely reduce durum wheat yield. Resistance to this pathogen is common in modern durum germplasm but is frequently based ...
Effect of allele combinations at Ppd‐1 loci on durum wheat grain filling at contrasting latitudes
(Wiley, 2019-09-15)
Flowering time is the most critical developmental stage in wheat, as it determines environmental conditions during grain filling. Thirty‐five spring durum genotypes carrying all ...
Agronomic performance of durum wheat landraces and modern cultivars and its association with genotypic variation in vernalization response (Vrn-1) and photoperiod sensitivity (Ppd-1) genes
(Elsevier, 2020-07-17)
This study analyzed the relationship between important agronomic traits and major genes regulating flowering time in a panel of 151 Mediterranean durum wheat landraces and 20 modern cultivars. Field ...
Allelic Variation at the Vernalization Response (Vrn-1) and Photoperiod Sensitivity (Ppd-1) Genes and Their Association With the Development of Durum Wheat Landraces and Modern Cultivars
(Frontiers Media, 2020-06-23)
Wheat adaptability to a wide range of environmental conditions is mostly determined by allelic diversity within genes controlling vernalization requirement (Vrn-1) and photoperiod sensitivity (Ppd-1). ...
