The current agricultural system is in search of new strategies to achieve a more sustainable production while keeping or even increasing crop yield and quality. In this scenario, the application of biostimulants constitutes a potent solution. In the current study, the impact of a blue-green microalgal extract (MB) and a pig tissue hydrolysate (PTH) on rapeseed plants' development was characterized.

- - This study explores how increased CO2 levels (e[CO2]) influence the photosynthesis of 42 different crop species under varying water and temperature conditions, analyzing nearly 3,000 data points from existing research.
- - For C3 plants, e[CO2] boosts net photosynthesis but leads to decreased stomatal conductance and a decline in Rubisco activity, while C4 crops show less sensitivity to these changes.
- - The research finds that the photosynthetic responses to e[CO2] remain consistent even under drought or heat stress, highlighting the complexity of plant reactions to climate change and its impact on agricultural resilience.
Post-translational redox modifications provide an important mechanism for the control of major cellular processes. Thioredoxins (Trxs), which are key actors in this regulatory mechanism, are ubiquitous proteins that catalyse thiol-disulfide exchange reactions. In chloroplasts, Trx f, Trx m and NADPH-dependent Trx reductase C (NTRC) have been identified as transmitters of the redox signal by transferring electrons to downstream target enzymes.

Here, we studied the influence of thioredoxin (Trx) m on C and N partitioning using tobacco plants overexpressing Trx m from the chloroplast genome. The transgenic plants showed altered metabolism of C (lower leaf starch and soluble sugar accumulation) and N (with higher amounts of amino acids and soluble protein), which pointed to an activation of N metabolism at the expense of carbohydrates.

The aim of this study was the characterisation of a collection of 69 yeast strains isolated from Spanish vineyards.
