Exploring Heat Stress Response in Genetically and Nutraceutically Diverse Tuscan Potato Landraces Using the Innovative Microcosmo Platform

Horticulturae, Journal Year: 2025, Volume and Issue: 11(4), P. 415 - 415

Published: April 13, 2025

The study investigated the physiological response to heat exposure of three potato landraces (Biancona del Faggeto, Rossa delle Macchie, and Quarantina Macchie), which are primarily grown in rural area Mount Amiata (Grosseto, Tuscany) distinguished by specific phylogenetic relationships nutraceutical composition. Nutraceutical genetic analyses were performed on tubers collected from field, whereas assessments conducted plants Microcosmo simulators. Overall, revealed tissue-specific differences distribution starch antioxidants, with ‘Biancona Faggeto’ ‘Quarantina Macchie’ accumulating more pulp than peel. level polyphenols antioxidants differed between peel, but they accumulated most peel ‘Biancona’. Phylogenetic analysis that ‘Rossa’ ‘Quarantina’ closely related Given ‘Biancona’ also contained others, this suggests a strong relationship phylogeny varieties their nutritional content. Heat stress reduced net carbon assimilation stomatal conductance all landraces, showing greatest reductions, indicating closure is primary limitation CO2 uptake. However, both maximum actual quantum yields photosystem II remained stable under stress, was not caused damage photosynthesis light-dependent reactions. These findings highlight complex interplay background capacity plants, as well adaptability withstand environmental stressors, provide valuable insights for breeding healthier heat-tolerant landraces.

Restoring functional farmland biodiversity for biological pest control

Trends in Plant Science, Journal Year: 2025, Volume and Issue: unknown

Published: April 1, 2025

Roughly 40% of global agri-food production is lost to pests during an era when productivity gains are essential humanity. Restoring farmland biodiversity for conservation biological control offers potential secure win-win outcomes yield and the environment. However, achieving this hindered by gaps in our understanding agrobiodiversity, including a lack data on occurrence, identity, interactions farm-dwelling (plant, animal, microbial) biota. Limited interdisciplinary collaboration weak policy frameworks exacerbate these issues. Comprehensive capture using standardized metrics, universal protocols, farmer-scientist cooperation, next-generation tools could consolidate evidence base which reform farming practice. This will involve ecologists stepping outside their comfort zones promote behavioral change make ecological intensification reality.
