Evidence for a defensive ceiling in the effectiveness of plant silicon defences against an insect herbivore

open access: yesEcological Entomology, EarlyView.
Silicon‐mediated resistance in wheat reaches a defensive plateau; accumulating silicon beyond 2mM provides no additional benefit for suppressing insect herbivore relative growth rates. Silicon supplementation significantly increases wheat biomass and effectively ameliorates plant mass losses caused by Helicoverpa armigera herbivory. Lower mandible wear

The bread of Toledo: Prices and political economy, 1535–1800

open access: yesThe Economic History Review, EarlyView.
Abstract We study the market for common white bread in the city of Toledo through a new 266‐year‐long series of bread prices, obtained from the cash purchases and wholesale bread‐for‐wheat contracts of large institutions. Our data are strongly consistent with fragmentary evidence on retail price regulation, as well as with shorter series from other ...

Regenerative wheat management: The relative effects of farm practices on the biodiversity of invertebrates

open access: yesInsect Conservation and Diversity, EarlyView.
Wheat in North America harbours a diverse insect community (565 morphospecies were identified in this study), and pests represented <7% of specimens collected. Regenerative wheat management promoted insect diversity without increasing pest populations.

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

open access: yesJournal 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

tRNA species in the developing grain of triticum aestivum

open access: yesPhytochemistry, 1975
The level of lysyl- and prolyl-tRNA in various stages of the maturing wheat grain was measured by the aminoacylation procedure. The levels of these tRNAs changed only slightly during the maturation period. Several species of lysyl- and prolyl-tRNA were obtained from different parts of the developing grain by fractionation on benzoylated-DEAE cellulose (

Effects of Early Season Temperature on Adult Life History Traits of Wheat Stem Sawfly, Cephus cinctus (Hymenoptera: Cephidae) and Bracon cephi (Hymenoptera: Braconidae)

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Wheat stem sawfly, Cephus cinctus Norton (Hymenoptera: Cephidae), is a long‐standing and serious pest of wheat, Triticum aestivum Linnaeus (Poaceae), in the northern Great Plains region of North America. Over the last decade, research efforts have aimed to better understand C.

High‐quality genome of elite peanut cultivar ZH05 reveals subgenome asymmetry, pan‐genome diversity, and breeding insights

open access: yesJournal of Integrative Plant Biology, EarlyView.
A high‐quality reference genome for the elite peanut cultivar Zhonghua No. 5 revealed differing evolutionary paths between the two peanut subgenomes. SubA has higher overall gene expression and more open chromatin, whereas SubB has stronger structural organization, higher DNA methylation, and greater adaptive diversity associated with peanut evolution ...
