Abstract

Analysis of durum wheat proteome changes under marine and fungal biostimulant treatments using large-scale quantitative proteomics: A useful dataset of durum wheat proteins.

Biostimulant Effects of Glutacetine® and Its Derived Formulations Mixed With N Fertilizer on Post-heading N Uptake and Remobilization, Seed Yield, and Grain Quality in Winter Wheat

“…As previously reported in durum wheat (Pichereaux et al, 2019), we observed deviations from the grain N concentration to grain yield negative correlation for VNT1-D2, VNT2 (doses 1 and 2), and VNT4 (doses 1 and 3). Bogard et al (2010) correlated this deviation to post-anthesis N uptake in winter wheat, which explains the results of VNT1-D2 and VNT4 ( Figure 3A).…”

“…Accordingly, in the present study, the protein content in wheat grain was highest in the control, whereas all of the formulations reduced it to 12.5% ( Table 1). Similar to our results, other biostimulants obtained from marine, fungal, or protein hydrolysates have not been shown to change the protein content in wheat (Popko et al, 2018;Pichereaux et al, 2019). However, none of the treatments from our work resulted in a protein content below the level required by the industry (11.5%) even though this is not the best criterion to ensure baking quality (Rossmann et al, 2019).…”

“…However, it is well documented that α-gliadins (Zörb et al, 2013) and 12S seed storage globulins (Gell et al, 2017) are initiators of the inflammatory response in celiac disease patients. In durum wheat, Pichereaux et al (2019) have reported the effects of marine and fungal biostimulant treatments on the grain proteome, and especially proteins involved in grain technological properties, such as the gluten protein gamma-gliadin, which increased 100fold following treatment. In contrast, our study suggests that application of Glutacetine R might improve grain quality through a decline in the immunogenic potential of wheat flour (Altenbach et al, 2020).…”

“…Biostimulants based on proteins or amino acids have enhanced N metabolism (Di Mola et al, 2020;Hassan et al, 2020), crop yield, grain characteristics, and the content of macro-and micronutrients in winter wheat (Popko et al, 2018). Regarding quality traits, plant biostimulants could affect durum wheat grain properties, changing the grain proteome (Pichereaux et al, 2019). Mineral interactions are also known to be essential for improving mineral use efficiency.…”

Marine and fungal biostimulants improve grain yield, nitrogen absorption and allocation in durum wheat plants

“…The objective of the current study was to quantify the effect of two biostimulants (marine, DPI4913, and fungal, AF086) used in foliar application on durum wheat, on important agronomic traits including yield and grain N relationships. Impacts on protein composition of these biostimulants have recently been described by Pichereaux et al (2019). The study, performed in greenhouse, has shown that DPI4913 and AF086 treatments promote grain yield while maintaining protein concentration in grains, and positively affect protein composition in terms of grain quality.…”
