To meet future requirements for food production, sustainable intensive agricultural systems need to optimize nutrient availability to maximize yield, traditionally achieved by maintaining soil pH within an optimal range (6-6.5) by applying lime (calcium carbonate). However, a field trial that applied recommended liming rates to a sandy loam soil (increasing soil pH from 5.5 to 6.2) decreased po...

Cereal-legume intercrops represent a promising way of combining high productivity and agriculture sustainability. The benefits of cereal-legume mixtures are highly affected by species morphology and functioning, which determine the balance between competition and complementarity for resource acquisition. Studying species morphogenesis, which controls plant architecture, is therefore of major in...

A lengthy cavity usually forms in the vascular cylinders of pea (Pisum sativum) primary roots in response to sudden flooding at 25°C. This is thought to be a form of aerenchyma. Ethylene has been shown to mediate inducible aerenchyma in maize, therefore the role of ethylene in the formation of cavities in pea roots was examined. Pea seedlings grown for 4 d in 2 L beakers in vermiculite moistene...

Significant increases in upa armigera in a wind-tunnel were obtained with air entrained headspace samples of African marigold, Tagetes erecta, flowers (P=0.014), and sweet pea, Lathyrus odoratus, flowers (P=0.047). Identification of the compounds contained in the Porapak Q extracts was done by GC-MS. Direct EAG was used to screen for the most electrophysiologically active natural extracts and G...

Sequence diversity of 39 dispersed gene loci was analyzed in 48 diverse individuals representative of the genus Pisum. The different genes show large variation in diversity parameters, suggesting widely differing levels of selection and a high overall diversity level for the species. The data set yields a genetic diversity tree whose deep branches, involving wild samples, are preserved in a tre...

In the recent paper published [1] in this journal, the efficacy and safety of a specific palmitoylethanolamide were reported: ultramicronized palmitoylethanolamide (PEA-um). This paper is one of recent series trying to convince readers that only a specific and patented formulation produced by the company Epitech Group S.r.L. in Italy is effective and has been explored sufficiently. This claim i...
