The study assessed three savory essential oil–based formulations for controlling early blight caused by Alternaria solani in tomato, finding that formulation CC2020 most effectively reduced disease severity in both in vitro and greenhouse trials. CC2020 also helped maintain tomato fruit vitamin C levels and lowered fungal melanin production, indicating dual benefits for disease suppression and fruit quality.
The study created a system that blocks root‑mediated signaling between wheat varieties in a varietal mixture and used transcriptomic and metabolomic profiling to reveal that root chemical interactions drive reduced susceptibility to Septoria tritici blotch, with phenolic compounds emerging as key mediators. Disruption of these root signals eliminates both the disease resistance phenotype and the associated molecular reprogramming.
The authors compiled and standardized published data on Rubisco dark inhibition for 157 flowering plant species, categorizing them into four inhibition levels and analyzing phylogenetic trends. Their meta‑analysis reveals a complex, uneven distribution of inhibition across taxa, suggesting underlying chloroplast microenvironment drivers and providing a new resource for future photosynthesis improvement efforts.
A BIOPOLYMER LAMINARIN ELICITS ANTIOXIDANT DEFENSE IN DIFFERENT CULTIVARS OF SOLANUM LYCOPERSICUM AGAINST EARLY BLIGHT DISEASE CAUSED BY ALTERNARIA SOLANI

The study investigates laminarin (LaM) as a biopolymer elicitor of antioxidative defenses in tomato against early blight caused by Alternaria solani. Laminarin pretreatment reduced pathogen colonization, increased hydrogen peroxide accumulation and guaiacol peroxidase activity, and lowered disease severity, highlighting its potential for sustainable disease management.
The study presents an optimized Agrobacterium-mediated transformation protocol for bread wheat that incorporates a GRF4‑GIF1 fusion to enhance regeneration and achieve genotype‑independent transformation across multiple cultivars. The approach consistently improves transformation efficiency while limiting pleiotropic effects, offering a versatile platform for functional genomics and gene editing in wheat.
