Salinity is one of the abiotic stress factors that affect plant physiology and cause various plant disorders. Thiourea, which consists of amino, thiol, and imino groups, is an antioxidant and growth regulator. The objective was to determine the antioxidant role of thiourea (0, 3, 6 mM) in attenuating the effects of salinity (0 mM, 50 mM, 100 mM NaCl) on growth, yield, and some biochemical compositions of flax ( L.

Hyaluronic acid (HA) exhibits various biological activities and functions, mainly governed by its molecular weight (M). Traditional HA degradation methods encounter challenges such as environmental pollution and high costs. Thus, developing a safe cell factory with an efficient regulation strategy for one-step production of specific M HA has attracted significant research interest.

Ammonium toxicity, resulting from prolonged use of ammonium as the sole nitrogen source, can lead to physiological and morphological disorders, ultimately stunting plant growth. Enhancing ammonium assimilation efficiency has been extensively explored as a strategy to mitigate ammonium toxicity. However, the role of AspAT, a key enzyme in nitrogen assimilation, remains underexplored.

This study investigated the effects of microwave treatment combined with lysine and arginine on gluten-free quinoa sponge cakes. The results indicated that the addition of these amino acids during microwave treatment significantly increased the cakes' specific volume by 49 %. X-ray diffraction analysis revealed that cake crystallinity reached 56.
