Resistant and susceptible pea lines harbour different root-rot pathogens and antagonistic fungi [PDF]
, 2019 Disease resistance encompasses the mechanisms that allow a plant to withstand or ward off a pathogen. The molecular responses of plants under pathogen attack and the underlying genetics have been extensively studied.

Spreading of virulence regarding spatial distribution resistant cultivars inferred from population modeling coupled with genetics [PDF]
, 2006 One of the control strategies of fungal crop diseases is planting highly resistant varieties. However selection pressure on the pathogen, imposed by major resistance genes, leads to the development of new virulent races.

Towards Reduced Pesticide Use for Cereal Crops in Asia [PDF]
Several opportunities are available for dramatically reducing the use of agrochemicals in Asian cereal crop production. The first section of this paper summarizes past trends and future prospects for pesticide use in Asia for the three major cereal crops:

How does SCYLV genetic diversity impact on Sugarcane disease resistance and breeding? [PDF]
, 2012 To date, six distinct genotypes of the Sugarcane yellow leaf virus have been described in the literature (BRA, CUB, CHN1, IND, PER and REU). However, little information is available regarding the impact of virus genetic diversity on disease resistance ...

PlantsPhenotyping yam (Dioscorea spp.) germplasm for resistance to parasitic nematodes is hampered by the lack of an efficient screening method. In this study, we developed a new method using rooted yam vine cuttings and yam plantlets generated from semi ...

Friedel oscillations induced surface magnetic anisotropy
, 2008 We present detailed numerical studies of the magnetic anisotropy energy of a magnetic impurity near the surface of metallic hosts (Au and Cu), that we describe in terms of a realistic tight-binding surface Green's function technique.

Transcriptional down-regulation of ccr5 in a subset of HIV+ controllers and their family members. [PDF]
, 2019 HIV +Elite and Viremic controllers (EC/VCs) are able to control virus infection, perhaps because of host genetic determinants. We identified 16% (21 of 131) EC/VCs with CD4 +T cells with resistance specific to R5-tropic HIV, reversed after introduction ...
