13. Dynamics of miR156 and miR172 involved in the flowering of Jatropha curcas L.
ABSTRACT Jatropha curcas is a plant that accumulates high-quality oil in its seeds, which is capable of being transformed into liquid biofuel. However, several aspects of its flowering are still unknown, which is a key step in the production of fruits, seeds, and oil. Flowering is a complex process that is regulated by various factors at the molecular level,

14. Factors that influence in Jatropha curcas L. latex production
ABSTRACT Latex from Jatropha curcas L. exhibits biotechnological potential for the development of biodiesel and drugs. Little is known about the collection methods and latex productivity of this species. In order to garner information on the use of J. curcas latex, factors that influence production by this species were assessed. As a result, no significant d

15. Associação e dependência micorrízica em mudas de Jatropha curcas L. sob estresse salino
RESUMO O cultivo de Jatropha curcas visando a produção de biodiesel é uma possibilidade para o uso de áreas salinizadas, no entanto a produção de biomassa nesses solos é limitada. Os fungos micorrízicos arbusculares (FMAs) são uma alternativa promissora para a biorremediação em solos salinizados. Porém, a salinidade também afeta os FMAs, no mo

16. Digestibility, growth, blood chemistry, and enzyme activity of juvenile Oreochromis niloticus fed isocaloric diets containing animal and plant byproducts
ABSTRACT In this work, we studied the digestibility, growth, blood chemistry, and enzyme activity of Nile tilapia (Oreochromis niloticus) juveniles (0.95±0.18 g) using different animal (fish silage meal, whey meal, bovine blood meal, and red crab meal) and plant (extruded bean, extruded chickpea meal, coconut paste, Jatropha curcas meal, and chickpea meal)

17. Physiological quality and seed respiration of primed Jatropha curcas seeds
ABSTRACT Seed deterioration is a natural and irreversible process. Nevertheless, seed priming with water and antioxidants can minimize oxidative damage in oilseeds, resulting in attenuation of seed deterioration. The objective of this assay was to evaluate seed priming on respiratory activity of Jatropha curcas submitted to accelerated aging. Seeds from two

18. Taxa de absorção de macronutrientes e partição de biomassa durante o crescimento inicial do pinhão-manso
RESUMO O óleo das sementes de pinhão-manso possui potencial para substituir combustíveis fósseis, porém o manejo nutricional para a espécie ainda não é totalmente descrito. O objetivo com esse trabalho foi estabelecer curvas de acumulo de macronutrientes em folhas, caule e raiz, bem como avaliar a taxa de crescimento relativo (TCR), taxa de crescimen

19. Differentiation of Toxic and Non-Toxic Leaves of Jatropha curcas L. Genotypes by Leaf Spray Mass Spectrometry
Jatropha curcas L. is an oil crop that has been studied as a potential source of biodiesel. A high protein pie is produced as a byproduct of the biodiesel production, which could be used as animal feed. However, the pie has toxic compounds, as phorbol esters and other toxins, which prevents the use as animal feed. For this reason, Embrapa (Brazilian Agricult

20. Multivariate Calibration to Determine Phorbol Esters in Seeds of Jatropha curcas L. Using Near Infrared and Ultraviolet Spectroscopies
The building of partial least squares (PLS) regression models using near infrared (NIR) and ultraviolet (UV) spectroscopies to estimate the concentrations of phorbol esters (PEs) in Jatropha curcas L. is presented. The models were built using two algorithms for variable selection, ordered predictors selection (OPS) and genetic algorithm (GA). Chromatographic

21. Qualidade fisiológica e conservação de sementes de Jatropha curcas em função da maturidade dos frutos
RESUMO O objetivo desse trabalho foi avaliar o efeito do estádio de maturação dos frutos na qualidade fisiológica das sementes de J. curcas L. durante o armazenamento. Assim, sementes foram extraídas de frutos colhidos em três estádios de maturação com base na coloração externa da casca, ou seja, amarelo, amarelo-marrom e marrom (frutos secos). Ap

22. MECANISMOS DE TOLERÂNCIA EM PLANTAS DE Hymenaea courbaril L. e Jatropha curcas L. EM RESPOSTA AO DEFICIT HÍDRICO E CONTAMINAÇÃO POR DERIVADOS DE PETRÓLEO
RESUMO Acidentes que ocorrem no processo de transporte do petróleo e de seus derivados têm sido um dos principais motivos de poluição ambiental nas últimas décadas. Pesquisas sobre alterações ocasionadas por estes poluentes na fisiologia de plantas ainda são escassos, sendo pouco conhecidos os efeitos ocasionados no metabolismo vegetal. Diante do ex

23. Overcoming crossing barriers between jatropha (Jatropha curcas L.) and castor bean (Ricinus communisL.)
Abstract A limitation in improvement of jatropha (Jatropha curcas) has been the low genetic variation among the available germplasm. An alternative to create genetic variability and incorporate desirable traits is through wide crossing. Due to reproductive barriers, wide crossing in jatropha has had limited success. In this experiment, intergeneric hybridiza

24. Lipase-catalyzed ethanolysis of Jatropha curcas L. oil assisted by ultrasonication
ABSTRACT Transesterification of non-edible oils using immobilized lipase is a promising process for biodiesel production. Thus, this study aimed to evaluate the enzymatic transesterification of the non-edible Jatropha curcas oil for FAEE production under ultrasound irradiation in a solvent-free system. The effects of enzyme concentration, water concentration
