Bioengineered xylanase from Misiones Argentina rainforest: A bakery enhancement approach.

In this study, we pursued the heterologous expression of the xylanase gene from Trichoderma atroviride, a native fungus in the province of Misiones, and used it to enhance the textural properties of baked goods through varying enzymatic concentrations. This marks the inaugural exploration into its functionality in the context of bread production. The recombinant xylanase exhibited improved activity, reaching 36,292 U L, achieved by supplementing the culture medium with dextrose.

Purification and characterization of a fungal laccase expressed in Kluyveromyces lactis suitable for baking.

Laccase enzyme can replace chemical additives to improve texture properties and the volume of bread. Laccase encoding gene from Phlebia brevispora, a native fungus from Misiones, Argentina, was expressed in the generally recognized as safe yeast Kluyveromyces lactis. To improve laccase activity, medium conditions were optimized.

Rhizogenic protein RolB interacts with the TOPLESS repressor proteins to reprogram plant immunity and development.

Rhizogenic strains comprise biotrophic pathogens that cause hairy root disease (HRD) on hydroponically grown and crops, besides being widely explored agents for the creation of hairy root cultures for the sustainable production of plant-specialized metabolites. Hairy root formation is mediated through the expression of genes encoded on the T-DNA of the root-inducing (Ri) plasmid, of which several, including (), play a major role in hairy root development. Despite decades of research, the exact molecular function of the proteins encoded by the genes remains enigmatic.

The basic helix-loop-helix transcription factors MYC1 and MYC2 have a dual role in the regulation of constitutive and stress-inducible specialized metabolism in tomato.

Plants produce specialized metabolites to protect themselves from biotic enemies. Members of the Solanaceae family accumulate phenylpropanoid-polyamine conjugates (PPCs) in response to attackers while also maintaining a chemical barrier of steroidal glycoalkaloids (SGAs). Across the plant kingdom, biosynthesis of such defense compounds is promoted by jasmonate signaling in which clade IIIe basic helix-loop-helix (bHLH) transcription factors play a central role.

Touch signaling and thigmomorphogenesis are regulated by complementary CAMTA3- and JA-dependent pathways.

Plants respond to mechanical stimuli to direct their growth and counteract environmental threats. Mechanical stimulation triggers rapid gene expression changes and affects plant appearance (thigmomorphogenesis) and flowering. Previous studies reported the importance of jasmonic acid (JA) in touch signaling.
