Reconsidering the importance of Metopolophium dirhodum (Walker) (Hemiptera: Aphididae) as a crop pest

open access: yesAgricultural and Forest Entomology, EarlyView.
Four‐year field monitoring and laboratory studies revealed M. dirhodum occurs regularly in barley with high reproductive potential and extended adult longevity. Populations peaked during vulnerable crop stages, creating optimal conditions for BYDV transmission during critical infection windows. M.

Transcription factors involved in cold response in plants. [PDF]

open access: yes, 2010
Studies in Arabidopsis have shown cold stress tolerance can be enhanced by manipulation of the CBF/DREB and ICE transcription factor genes. To date, few studies have investigated CBF and ICE genes in crops species such as barley. Using a C-repeat element

Exploring Use‐Wear Texture Quantification Through Confocal Microscopy on Tools Made From Volcanic Rocks (Basalt and Phonolite)

open access: yesArchaeometry, EarlyView.
ABSTRACT Functional analysis is essential for reconstructing lithic tool use. Recent approaches combining confocal microscopy and surface texture analysis provide quantitative alternatives to traditional visual use‐wear analysis, although their application to coarse‐grained, heterogeneous rocks remains challenging because of their complex surface ...

Agrobacterium-mediated barley transformation. [PDF]

open access: yes, 2008
More than ten years have passed since the first successful Agrobacterium-mediated barley transformation experiment, however it is still quite challenging to establish a stably functioning agroinfiltration protocol.

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

open access: yesEcological 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.

The use of the ph1b mutant to induce recombination between the chromosomes of wheat and barley

open access: yesFrontiers in Plant Science, 2015
Intensive breeding has led to a narrowing in the genetic base of our major crops. In wheat, access to the extensive gene pool residing in its many and varied relatives (some cultivated, others wild) is hampered by the block on recombination imposed by ...

Natural variation in the GNH1 promoter enhances plant height and grain yield in rice

open access: yesJournal of Integrative Plant Biology, EarlyView.
Natural variation in the GRAIN NUMBER AND PLANT HEIGHT 1 (GNH1) promoter alleviates repression by the C2H2‐type transcription factor ZFP36, upregulating GNH1 expression and promoting auxin accumulation, thereby increasing rice plant height and grain yield. This elite allele serves as a valuable genetic resource for molecular breeding of high‐yield rice.

Efficiency of RNAi‐based gene silencing in fungi: a meta‐analysis

open access: yesNew Phytologist, EarlyView.
Mechanistic interpretation of RNAi efficiency across fungal lifestyles and delivery strategies based on the present meta‐analysis. Summary RNA interference (RNAi) shows great potential to protect crops against fungal diseases, yet reported protection efficiencies vary greatly, and our understanding of the factors responsible for this variance remains ...

The spatial structure of small mammals (Eulipotyphla, Rodentia) in ecological and conventional farming conditions

open access: yesAgrology, 2022
Ecological farming is more environmental friendly than conventional farming and promotes habitat heterogenity. Changes in dispersion and structures of small mammals reflected quality of habitats in agriculture landscape.
