Declarations

:

: Not applicable, as the research did not involve human participants or vertebrate animals.: This study was conducted exclusively with microorganisms and plants obtained from legally authorized sources. Carrot (Daucus carota)cv. Nantes and cauliflower (Brassica oleracea var. botrytis) cv. Four Seasons seeds were purchased from Isla Seeds company (Brazil). No collection of wild plant material was performed, and therefore no specific permits or licenses were required. All procedures complied with institutional and national guidelines for the use of commercially available plant material in research, in accordance with Brazilian regulations (MAPA—Ministério da Agricultura e Pecuária, Normas e Padrões de Sementes e Mudas). Regarding the isolation of the yeast strain, floral nectar was sampled non-destructively from Senna macranthera flowers cultivated in the garden of the Federal University of Fronteira Sul (Chapecó, Santa Catarina, Brazil). No part of the plant was removed or damaged during sampling. According to Brazilian legislation, no special authorization is required for this type of non-destructive collection, unless the microbial strain is transferred abroad. The yeast isolate (Rhodotorula sp. CHAP-208) has been formally deposited in the institutional microbial culture collection and registered in the Brazilian SISGEN system (National System for the Management of Genetic Heritage and Associated Traditional Knowledge, Process number AD9213D, Chico Mendes Institute for Biodiversity Conservation), ensuring full compliance with national biodiversity regulations.
