Abstract:
... This work explores the use of chitosan as an active matrix to develop biofungicides. Two chitosans from marine resources, of 4.8 and 78 kg/mol respectively, were structurally characterized. Both chitosans diluted in acidic conditions (lactic or acetic acid at 1%, v/v) were efficient in reducing the growth of Fusarium graminearum. Ammonium groups of chitosan chains were suggested as key determinant ...

Abstract:
... BACKGROUND: Fusarium head blight (FHB) caused by Fusarium graminearum is a devastating fungal disease of wheat. The mechanism underlying F. graminearum-wheat interaction remains largely unknown. tRNA-derived fragments (tRFs) are RNase-dependent small RNAs derived from tRNAs, and they have not been reported in wheat yet, and whether tRFs are involved in wheat-F. graminearum interactions remains unk ...

Abstract:
... Oats (Avena sativa L.) are well known for their nutritional properties but are susceptible to the growth of different Fusarium fungi resulting in mycotoxin contamination of harvested oats. In this study, oat samples from harvest years 2011 to 2017 were preselected for their suitability as milling oats for food purposes with DON contents below 1750 µg/kg. The reduction of DON, T-2 and HT-2 toxins d ...

Scientists have been working on different strategies for DON detoxification, with biological detoxification being an approach with growing interest. When evaluating the use of microorganisms for mycotoxin detoxificati ...

Abstract:
... The jasmonic acid (JA) signaling pathway is involved in plant growth, development, and response to abiotic or biotic stresses. MYC2, a bHLH transcription factor, is a regulatory hub in the pathway. The function of ZmMYC7, a putative MYC2 ortholog, in jasmonate-signaled defense responses of maize has not been reported. In this study, we found that ZmMYC7 possesses JID, TAD, bHLH and Zip domains and ...

Abstract:
... Fungal pathogens produce a broad array of secondary metabolites (SMs), which allow the fungus to thrive in its natural habitat and gain competitive advantage. Analysis of the genetically encoded blueprints for SM assembly highlighted that only a small portion of the SMs these fungi are capable of producing are known, and even fewer have been investigated for their natural function. Using molecular ...

Abstract:
... Because Fusarium head blight (FHB) intensity is usually highly variable within a plot, the number of spikes rated for FHB index (IND) quantification must be considered when designing experiments. In addition, quantification of sources of IND heterogeneity is crucial for defining sampling protocols. Field experiments were conducted to quantify the variability of IND (“field severity”) at different ...
