Genome-Wide Association Study of Leaf Rust and Stem Rust Seedling and Adult Resistances in Tetraploid Wheat Accessions Harvested in Kazakhstan

open access: yesPlants, 2022
Leaf rust (LR) and stem rust (SR) are diseases increasingly impacting wheat production worldwide. Fungal pathogens producing rust diseases in wheat may cause yield losses of up to 50–60%.

Host resistance and the evolutionary response of plant viruses

open access: yes, 2006
1. Plant virus diseases severely constrain agricultural production world-wide, especially in less developed countries. The use of resistant cultivars may put a selection pressure on the plant virus to evolve towards more aggressive types.

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Identification and Validation of a Common Stem Rust Resistance Locus in Two Bi-parental Populations

open access: yesFrontiers in Plant Science, 2018
Races belonging to Ug99 lineage of stem rust fungus Pucciniagraminis f. sp. tritici (Pgt) continue to pose a threat to wheat (Triticumaestivum L.) production in various African countries.

Mining of Indian wheat germplasm collection for adult plant resistance to leaf rust. [PDF]

open access: yesPLoS One, 2019
Leaf rust (Puccinia triticina Eriks.) is a fungal disease of wheat (Triticum spp.), which causes considerable yield loss. Adult plant resistance (APR) is one of the most sustainable approaches to control leaf rust. In this study, field-testing was carried out across ten different locations, followed by molecular screening, to detect the presence of APR

A multiple resistance locus on chromosome arm 3BS in wheat confers resistance to stem rust (Sr2), leaf rust (Lr27) and powdery mildew

open access: yes, 2011
Sr2 is the only known durable, race non-specific adult plant stem rust resistance gene in wheat. The Sr2 gene was shown to be tightly linked to the leaf rust resistance gene Lr27 and to powdery mildew resistance.

Loss of susceptibility as a novel breeding strategy for durable and broad-spectrum resistance [PDF]

open access: yes, 2010
Recent studies on plant immunity have suggested that a pathogen should suppress induced plant defense in order to infect a plant species, which otherwise would have been a nonhost to the pathogen. For this purpose, pathogens exploit effector molecules to

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions

open access: yesFEBS Letters, EarlyView.
The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

open access: yesFEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

Adult Plant Resistance to Stem Rust and Molecular Marker Analysis of some Egyptian and Exotic Bread Wheat Genotypes [PDF]

open access: yesJournal of Plant Protection and Pathology, 2018
Stem rust caused by Puccinia graminis f. sp. tritici is the most dangerous and common disease among global wheat cultivars. Twelve local Egyptian and four exotic genotypes of bread wheat (Triticum aestivum L.) obtained from the International Maize and ...
