MetabolomicsElevated CO2 and virus infection impacts wheat and aphid metabolism

INTRODUCTION: The aphid Rhopalosiphum padi L. is a vector of Barley yellow dwarf virus (BYDV) in wheat and other economically important cereal crops. Increased atmospheric CO2 has been shown to alter plant growth and metabolism, enhancing BYDV disease in wheat. However, the bioch...

MetabolomicsSynthetic Microbial Communities Improve Wheat Stem Base Rot and Promote Wheat Growth by Regulating Rhizosphere Microbial Communities

Background

Wheat crown rot (WCR) caused by Fusarium spp. lacks durable, sustainable control. Engineering the rhizosphere with defined synthetic microbial communities (SynComs) offers a route to combined disease suppression and growth promotion. We aimed to build a cross-kingdom SynCom and e...

MetabolomicsMetabolic analysis of two wheat (Triticum aestivum) cultivars in response to Russian wheat aphid (Diuraphis noxia Kurdjumov) infestation
Wheat is one of the most widely consumed cereal grains globally and plays a critical role in food security. As a staple crop in many households, it provides essential nutrients and contributes significantly to daily caloric intake. Although wheat is attacked by multiple pests, the Russian wheat aphi...

MetabolomicsWheat growth, applied water use efficiency and flag leaf metabolome under continuous and pulsed deficit irrigation

The intensity and frequency of precipitation events are predicted to change over the coming decades. For many areas, longer periods without rainfall are expected. We investigated the importance of irrigation frequency under water deficit conditions for growth, physiology and chemistry of wheat (<...

MetabolomicsGC-MS based targeted metabolic profiling identifies changes in the wheat metabolome following deoxynivalenol treatment
Fusarium graminearum and related species commonly infest grains causing the devastating plant disease Fusarium head blight (FHB) and the formation of trichothecene mycotoxins. The most relevant toxin is deoxynivalenol (DON), which acts as a virulence factor of the pathogen. FHB is difficult to contr...

MetabolomicsBioinspired Rhamnolipid Protects Wheat Against Zymoseptoria tritici Through Mainly Direct Antifungal Activity and Without Major Impact on Leaf Physiology

Rhamnolipids (RLs), glycolipids biosynthesized by the Pseudomonas and Burkholderia genera, are known to display various activities against a wide range of pathogens. Most previous studies on RLs focused on their direct antimicrobial activity, while only a few reports described t...

MetabolomicsIntegrated GWAS and metabolomic analyses identified metabolic pathways and candidate genes involved in free asparagine accumulation in durum wheat grain

Free asparagine content is a key factor in acrylamide formation in wheat derivatives after high temperature processing. Therefore, the control of free asparagine levels is of interest in crop and food sciences. Our study aims to explore the natural variation in durum wheat to identify candidate g...

MetabolomicsAroma and quality of breads baked from old and modern wheat varieties and their prediction from genomic and flour-based metabolite profiles
Bread aroma is the principal characteristic perceived by the consumer yet it is mostly disregarded in the product chain. The main aim of this study was to evaluate the potential to include bread aroma as a new target criterion into the wheat product chain. The objectives of our study were to (i) qua...
