Characterization of molecular diversity and genome-wide mapping of loci associated with resistance to stripe rust and stem rust in Ethiopian bread wheat accessions

BMC Plant Biology, 2017
Background The narrow genetic basis of resistance in modern wheat cultivars and the strong selection response of pathogen populations have been responsible for periodic and devastating epidemics of the wheat rust diseases.

Wheat germplasm screening for stem rust resistance using conventional and molecular techniques

Czech Journal of Genetics and Plant Breeding, 2011
In Central Asia, stem rust (Puccinia graminis f.sp. tritici) causes considerable damage, especially during growing seasons with high rainfall. Ug99 is a race of stem rust that is virulent to the majority of wheat varieties.

Combining Ability for Earliness, Agronomic and Leaf and Stem Rusts Resistance Traits in F1 And F2 Bread Wheat Diallel Crosses [PDF]

Journal of Plant Production, 2016
Six bread wheat parents and their diallel F1 (in 2012/13 season) and F2's (in 2013/14 season) hybrids were evaluated to estimate combining ability for earliness, agronomic and leaf and stem rusts resistance traits.

Screening of CIMMYT Wheat Genotypes to Stem Rust Disease under Field Conditions in Egypt غربلة التراکيب الوراثية لقمح السيميت ضد مرض صدأ الساق تحت ظروف الحقل في مصر [PDF]

Journal of Plant Protection and Pathology, 2020
Among 190 wheat genotypes (CIMMYT), 51 lines were evaluated for adult plant resistance (APR) to stem rust infection at Sakha, Kafr El-Hamam and Nubaria locations, as the new sources of this resistance.

Genetic analysis of rust resistance genes in global wheat cultivars: an overview

Biotechnology & Biotechnological Equipment, 2017
Rust is the most devastating fungal disease in wheat. Three rust diseases, namely, leaf or brown rust caused by Puccinia triticina Eriks, stem or black rust caused by Puccinia graminis f. sp.

PHYSIOLOGICAL RACES AND VIRULENCE DIVERSITY OF WHEAT STEM RUST FUNGUS Puccinia graminis f. sp. tritici IN EGYPT DURING 2012-2013 [PDF]

Journal of Plant Protection and Pathology, 2015
Stem rust collections were obtained from infected wheat stems throughout the survey of wheat fields and nurseries in (Garbia, Dakhlia, Minofia, Kafer Elshake and Sharkia governorates) during 2012/2013.

Entropy‐Driven Design of Low‐Melting‐Point Alloys via Compositionally Complex Strategy

Advanced Engineering Materials, EarlyView.
Conventional low‐melting‐point alloys (LMPAs) are limited by a narrow compositional space and inherent property trade‐offs. This review presents an entropy‐driven design strategy that overcomes these limitations, ushering in a new class of low‐melting‐point compositionally complex alloys (LMCCAs).

The Role of Ultra‐Thin Passive Films and Organic Adsorbates on Aluminum Chips for a Friction‐Induced Solid‐State Recycling Process

Advanced Engineering Materials, EarlyView.
Despite benefits to storage stability and handleability of aluminum scrap, octadecyl phosphonic acid (ODPA) SAMs reduce the tensile strength of wires produced using friction‐induced recycling. Etching and methyl diphosphonic acid (MDPA) coatings, however, have little effect.

An Integrated Oxygen‐Supplying Device and Predictive Multiphysics Model for Extended Ambient Transport of Insulin‐Producing Cells

Advanced Functional Materials, EarlyView.
Cell therapies typically rely on cold‐chain logistics and cryopreservation, limiting access and compromising cell quality. Here, a dual‐chamber device separates an oxygen‐supplying chamber from a hyaluronic acid cargo chamber, sustaining oxygen delivery for over 70 h and enabling ambient‐temperature shipment.
