Enhanced abiotic stress tolerance in Arabidopsis overexpressing Ricinus communis FeSOD8 (RcFeSOD8).

Ricinus communis L. is a globally relevant industrial oilseed crop mostly cultivated in tropical arid/semi-arid areas, where abiotic stresses frequently limit crop establishment and productivity. Superoxide dismutase (SOD) is an antioxidant enzyme acting as a primary defense against oxidative stress in plants subjected to abiotic stresses, localized in various subcellular compartments, and classified in eukaryotes according to metal cofactors.

Cross-cultural adaptation of the Voice-related Experiences of Nonbinary Individuals - VENI to Brazilian Portuguese.

Purpose: This study aimed to translate and cross-culturally adapt the "Voice-related Experiences of Nonbinary Individuals" (VENI) to Brazilian Portuguese (BP).

Methods: Cross-cultural adaptation was performed based on the combined guidelines of the World Health Organization's (WHO) Translation Recommendations and the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN). The process included five stages: a) Translation of the instrument into BP by a translator specialized in the construct and a non-specialist, both native BP speakers and fluent in English; b) Synthesis of the two translations by consensus; c) Back-translation by a translator specialized in the construct and a non-specialist, both native English speakers and fluent in BP; d) Analysis by a committee of five speech-language pathologists voice specialist and the creation of the final version; e) Pre-testing with 21 individuals from the target population, conducted virtually.

Castor (Ricinus communis L.) differential cell cycle and metabolism reactivation, germinability, and seedling performance under NaCl and PEG osmoticum: Stress tolerance related to genotype-preestablished superoxide dismutase activity.

Castor (Ricinus communis) is a relevant industrial oilseed feedstock for many industrial applications, being globally mainly cultivated by smallholder farmers in semiarid areas, where abiotic stresses predominate. Therefore, susceptible to generating reactive oxygen species (ROS) and subsequent oxidative stress, compromising cell metabolism upon seed imbibition and germination, seedling and crop establishment, and yield. The present study evaluated the consequences of water restriction by Polyethylene glycol (PEG) and Sodium chloride (NaCl) on cell cycle and metabolism reactivation on germinability, seedling growth, and vigor parameters in 2 commercial castor genotypes (Nordestina and Paraguaçu).
