Hemipteran vectors of stylet‐borne plant viruses: Aphids lead the charge

Insect Science, EarlyView.
Among all sap‐feeding hemipterans, aphids stand out by far as the most important vectors of noncirculative plant viruses. Compared to whiteflies and mealybugs, aphids’ highly specialized stylet anatomy and distinct feeding behaviors contribute, together with other features of their biology, to their remarkable efficiency in transmitting stylet‐borne ...

A global assessment of the viruses transmitted by the peach‐potato aphid (Myzus persicae)

Agricultural and Forest Entomology, EarlyView.
The viruses transmitted by Myzus persicae, including proportions by family, order and transmission type (persistent, semi‐persistent and non‐persistent), are provided. Latin binomials and common names are documented for each virus Virus presence in GB matches well with the rest of NW Europe, but with 25 exceptions.

Breathing in Plants and Chaos—Cosmic Tree Events in Cameroon and Beyond

Anthropology of Consciousness, EarlyView.
ABSTRACT Contemporary practices of tapping into the wisdom of ancestral trees are described through three entangled recent events lived within the context of Bantu practices in Cameroon. In the three instances, the steered or chance encounters with high potency trees were serendipitous telling moments which brought something new to the horizon.

Screening for resistance of the common bean genotypes to common bacterial blight, and bean common mosaic virus

East African Journal of Science, Technology and Innovation, 2023
Common bacterial blight (CBB), and bean common mosaic (BCMV) limit common beans (Phaseolus vulgaris L.) production worldwide. This study was carried out to perform phenotypic screening and asses the leaf reaction of a resistant line to CBB and BCMV. The experiment was conducted using a Completely Randomized design with three replications under screen ...

Analysis of 3′-Terminal Region of Bean common mosaic virus Strains Infecting Common Bean in India [PDF]

Indian Journal of Virology, 2011
Four strains (NL-1, NL-1n, NL-7 and NL-7n) of Bean common mosaic virus (BCMV) prevalent on common bean (Phaseolus vulgaris) in Himachal Pradesh, a north-western Himalayan state of India were compared at the 3' terminal region of the viral genome to elucidate variation and relationship among these strains.

A defensive symbiont and a plant virus confer direct and discrete phenotypes to a cereal aphid in a context‐dependent manner

Ecological Entomology, EarlyView.
Different BYDV‐PAV isolates exert contrasting effects on aphid fitness, including reproduction and winged production. Different BYDV‐PAV isolates have contrasting effects on aphid dispersal patterns. Aphid feeding behaviour is modulated by the presence of endosymbionts and plant viruses.

A Quantitative Method to Screen Common Bean Plants for Resistance to Bean common mosaic necrosis virus [PDF]

Phytopathology®, 2003
A quantitative method to screen common bean (Phaseolus vulgaris) plants for resistance to Bean common mosaic necrosis virus (BCMNV) is described. Four parameters were assessed in developing the quantitative method: symptoms associated with systemic virus movement, plant vigor, virus titer, and plant dry weight.

Differential Varietal Responses in Faba Bean Concerning Pea Aphid and Pea Necrotic Yellow Dwarf Virus (PNYDV) When Intercropped With Oat

Journal of Applied Entomology, EarlyView.
ABSTRACT The pest status of pea aphid (Acyrthosiphum pisum H.) in faba bean (Vicia faba L.) cultivation has gained importance because it transmits Pea necrotic yellow dwarf virus (PNYDV), a novel nanovirus in Europe. This study evaluated two faba bean varieties, ‘Fuego’ and ‘GL Sunrise’, grown under sole crop (SC) and intercrop (IC) conditions with oat

Metagenomic Analysis of Plant Virus Occurrence in Common Bean (Phaseolus vulgaris) in Central Kenya

Frontiers in Microbiology, 2018
Two closely related potyviruses, bean common mosaic virus (BCMV) and bean common mosaic necrosis virus (BCMNV), are regarded as major constraints on production of common bean (Phaseolus vulgaris L.) in Eastern and Central Africa, where this crop provides

The TaRNS4–TaPP2C10 module regulates wheat resistance to stripe rust through RNA degradation and MAPK cascades

Journal of Integrative Plant Biology, EarlyView.
In wheat, phosphorylation of the S‐like RNase TaRNS4 mediated by the kinase TaRLK5 promotes its degradation of Puccinia striiformis f. sp. tritici RNA in the apoplast, enhancing resistance to stripe rust. TaRNS4 can hijack phosphatase TaPP2C10 to relieve its dephosphorylation of TaMAPK6, thereby activating MAPK‐mediated immune responses. ABSTRACT RNase
