Autoria: LIMA, C. E. P.; AMORIM, J. R. A. de; CRUZ, M. A. S.; FONTENELLE, M. R. Conteúdo: This study presents local-scale (1 km²) climate projections for the Lower São Francisco region, located between the states of Sergipe and Alagoas (Brazil). Projections were derived from the ACCESS-CM2 model using the WorldClim database. The exclusive use of ACCESS-CM2 is justified by its physical consistency for the Brazilian territory. Key climatic variables - minimum temperature (Tmin), maximum temperature (Tmax), and precipitation (Prec) - were mapped for four SSPs scenarios up to 2100. The methodology was based on automated workflows developed with the support of generative artificial intelligence and collaborative platforms, which were used to build Python scripts executed in PyQGIS. FAIR and open science principles were adopted with all data deposited on public Zenodo repositories. Results indicate a strong warming trend, with Tmax increases up to 6°C and Tmin up to 5°C, accompanied by reductions in annual precipitation exceeding 250 mm. The rainy season may be shortened from five to three months. These changes pose severe risks to water availability, agricultural productivity, and farmers’ livelihoods, potentially leading to food, nutritional and water insecurity in this socioeconomically and climate vulnerable region. There is urgent need to adopt resilient and adapted strategies. Climate-smart public policies and agricultural systems must be developed, implemented and piloted. As this is a socioeconomically and climatically vulnerable region, this study serves as support for the IPCC climate justice and just transition frameworks. 2026-01-01T00:00:00Z https://www.alice.cnptia.embrapa.br/alice/handle/doc/1186378 Título: Chemistry composition and bioaccessibility study ofPhenolic compounds and carotenoids of new brazilian biofortified sweet potato “CIP BRS Nuti” Autoria: SILVA, M. C. C. da; MONTEIRO, L. I. da S.; PRADO, D. de S.; CARVALHO, A. J. de B. A.; MAGNANI, M.; MELLO, A. F. S.; GOMES, E. C. de S.; LIMA, M. dos S. Conteúdo: Sweet potatoes biofortified in carotenoids have been an alternative to combat malnutrition in vulnerable populations. This workis the first comprehensive study of the bioactive potential of the new Brazilian biofortified sweet potato cultivar “CIP BRS Nuti.”In two harvests, the chemical composition and profiles of organic acids, phenolic compounds, and carotenoids were analyzedusing high‐performance liquid chromatography. The bioaccessibility of phenolics and carotenes was also studied. The mainsimple sugars and organic acids found were glucose, fructose, citric, malic, succinic, and lactic acids. “CIP BRS Nuti” showedhigh concentrations of chlorogenic acid (228.3–330.4 mg/kg) and hesperidin (385.2–530.9 mg/kg), with the presence of otherphenolics such as catechin, epicatechin, and procyanidin B1, with high levels of bioaccessibility (> 104%). The main carotenoidquantified was 9‐cis‐β‐carotene (294.9–503.8 mg/kg), with low bioaccessibility, but β‐carotene and lycopene were also present.Our results show the nutritional and bioactive potential of the “CIP BRS Nuti” potato, providing essential information for its usein food and industrialization, with an applied view to nutrition and food science. 2026-01-01T00:00:00Z https://www.alice.cnptia.embrapa.br/alice/handle/doc/1186122 Título: Copper resistance and hormetic-like response in Xanthomonas euvesicatoria pv. perforans. Autoria: SILVA, E. L. da; ROSSATO, M.; QUEZADO-DUVAL, A. M.; FERREIRA, M. A. da S. V. Conteúdo: Bacterial spot caused by X. euvesicatoria pv. perforans in Brazil shows copper resistance via the copA gene. The study identified resistance in 28.8% of isolates and reported, for the first time, a hormetic effect (low-dose stimulation), as well as increased biofilm under copper stress. 2026-01-01T00:00:00Z https://www.alice.cnptia.embrapa.br/alice/handle/doc/1185797 Título: Produção de sementes de hortaliças em cultivo protegido. Autoria: GUEDES, I. M. R. Conteúdo: Apresenta o cultivo protegido no Brasil, cujo objetivo é controlar fatores climáticos e biológicos para garantir a qualidade das sementes. O manejo exige rigor na nutrição mineral e fertirrigação para evitar a salinização do solo. O sucesso depende do controle térmico e fitossanitário adequado. 2016-01-01T00:00:00Z
