Differential Impacts of Virus Diversity on Biomass Production of a Native and an Exotic Grass Host.
Pathogens are common and diverse in natural communities and have been implicated in the success of host invasions. Yet few studies have experimentally measured how pathogens impact native versus exotic hosts, particularly when individual hosts are ...

Metopolophium festucae cerealium (Hemiptera: Aphididae) : a new addition to the aphid fauna of North America [PDF]
Metopolophium festucae cerealium (Stroyan) (Hemiptera: Aphididae) was found in wheat fields in the Pacific Northwest in 2011 and 2012. This is the first record of M. f. cerealium in North America.

ABSTRACT Plant viruses frequently cause severe economic losses in worldwide crop production. Developing broad‐spectrum resistance is the most efficient approach for controlling plant viral diseases. In this work, we found that the 17K protein of barley yellow dwarf viruses (BYDVs), which has multiple functions in viral pathogenesis including acting as ...

Unfolding Plant Defence: Endoplasmic Reticulum Stress Signalling at the Plant‐Pathogen Interface
ABSTRACT The endoplasmic reticulum (ER) stress response, a conserved proteostasis network, has emerged as a central hub that reprograms plant immunity during pathogen attack. This review synthesises how plants harness ER‐stress signalling to mount multilayered defences and how pathogens have evolved counterstrategies to subvert these pathways.

Yellow dwarf viruses (YDVs) are the most economically important plant viruses impacting cereal production worldwide and include viruses from the genus Luteovirus (e.g., barely yellow dwarf virus (BYDV)-PAV, BYDV-PAS, BYDV-MAV, BYDV-kerII, BYDV-kerIII ...

Agronomical, biochemical and histological response of resistant and susceptible wheat and barley under BYDV stress [PDF]
Barley yellow dwarf virus-PAV (BYDV-PAV) is one of the major viruses causing a widespread and serious viral disease affecting cereal crops. To gain a better understanding of plant defence mechanisms of BYDV resistance genes (Bdv2 and RYd2) against BYDV ...

A 212-nt long RNA structure in the Tobacco necrosis virus-D RNA genome is resistant to Xrn degradation [PDF]
Plus-strand RNA viruses can accumulate viral RNA degradation products during infections. Some of these decay intermediates are generated by the cytosolic 5′-to-3′ exoribonuclease Xrn1 (mammals and yeast) or Xrn4 (plants) and are formed when the enzyme ...

Herbicide residues in soil disrupt plant–insect signalling, reducing the effectiveness of biological pest control. Abstract Plants under herbivore attack emit distinct blends of herbivore‐induced plant volatiles (HIPVs) which serve as signalling cues for predatory insects.

Introgression of barley yellow dwarf virus resistance into Tunisian barley varieties [PDF]
The original objective of cross breeding was to develop high-yielding spring barley with high barley yellow dwarf virus resistance. Imen is an F5-derived line with the original experimental number 137. A single seed selection breeding method was used to develop the cultivar. Imen is well adapted to semi-arid areas, carrying the resistant gene Yd2.

CM 67 and Atlas 68… two new yellow-dwarf resistant barley varieties
BARLEY YELLOW DWARF, an apid-transmitted virus disease of small grains, has caused serious losses in barley, wheat, and oats in California since its sudden widespread outbreak in 1952.
