The development of nondestructive technology for the detection of seed viability is challenging. In this study, to establish a green and effective method for the viability assessment of single maize seeds, a two-stage seed viability detection method was proposed. The catalase (CAT) activity and malondialdehyde (MDA) content were selected as the most key biochemical components affecting maize seed viability, and regression prediction models were developed based on their hyperspectral information and a data fusion strategy. Qualitative discrimination models for seed viability evaluation were constructed based on the predicted response values of the selected key biochemical components. The results showed that the double components thresholds strategy achieved the highest discrimination accuracy (92.9%), providing a crucial approach for the rapid and environmentally friendly detection of seed viability.

The increasing contamination of cereals by micromycetes and mycotoxins during malting still poses an unresolved food safety problem. This study characterises the potential of the novel, rapidly developing food production technology of Pulsed Electric Field (PEF) to reduce the viability of fungi and the production of mycotoxins during malting. Barley, artificially inoculated with four species, was treated by PEF with two different intensities and then malted using a standard Pilsner-type technology.

Background: is a member of the lactic acid bacterium group commonly found in many salt-fermented foods. Strains of isolated from high-salinity environments have been shown to tolerate salt stress to some extent. However, the specific responses and mechanisms of under salt stress are not fully understood.

Phosphorus (P) is an essential macronutrient for the growth and yield of crops. However, there is limited understanding of the regulatory mechanisms of phosphate (Pi) homeostasis, and its impact on growth, development, and yield-related traits in Brassica napus. Here, we identified four NITROGEN LIMITATION ADAPATATION1 (BnaNLA1) genes in B.

Currently, the use of bio-inputs is increasing due to the need to reduce the use of agrochemicals. However, one of the limitations is to preserve the viability of the living microorganisms, so it is important to find an alternative that allows us to obtain different metabolites to produce it. We evaluated three different interactions (contact, diffusible and volatile compounds) in (At) seedlings with the strain M10 and its filtered secondary metabolites (M10F).

Null mutations for genes encoding a major seed storage protein in pea, vicilin, were sought through screening a fast-neutron mutant population. Deletion mutations at four or five vicilin loci, where all vicilin genes within each locus were deleted, were combined to address the question of how removal or reduction of a major storage protein and potential allergen might impact the final concentration of protein per unit mature seed weight, seed yield and viability. While the concentration of seed protein was not reduced in mature seeds of mutant lines, indicative of a re-balancing of the proteome, notable differences were apparent in the metabolite, proteomic and amino acid profiles of the seeds, as well as in some functional properties.
