“…High homozygosity and genetic uniformity were observed among physic nut accessions cultivated in several countries in South America, Africa, and Asia, and supports the general idea that the region of the Mexican Central America and Guatemala is the center of origin and presents wide genetic variability and levels of heterozygosity (Trebbi et al, 2015).…”

ABSTRACT. Physic nut (Jatropha curcas L.) presents high oilseed yield and low production cost. However, technical-scientific knowledge on this crop is still limited. This study aimed to evaluate and estimate the genetic variability of hybrids obtained from dialell crossing. Genetic variability was carried out using ISSR molecular markers. For genetic variability, nine primers were used, and six were selected with 80.7% polymorphism. Genetic similarity was obtained using the NTSYS pc. 2.1 software, and cluster analysis was obtained by the UPGMA method. Mean genetic similarity was 58.4% among hybrids; the most divergent pair was H1 and H10 and the most similar pair was H9 and H10. ISSR PCR markers provided a quick and highly informative system for DNA fingerprinting, and also allowed establishing genetic relationships of Jatropha hybrids.

“…A high degree of homozygosity plus a high genetic uniformity was reported among 907 accessions collected worldwide [65]. Similar results of high genetic uniformity and homozygosity of J. curcas accessions grown in several countries of South America, Africa, and Asia further supported the idea of the Mexico-Central America region as the center of origin of the Jatropha species [66].…”

Growing Jatropha (Jatropha curcas L.) as a Potential Second-Generation Biodiesel Feedstock

et al. 2021

Dwindling supplies of fossil fuels and their deleterious impacts on human health and the global environment have intensified the search for substitute energy sources. Biodiesel has been identified as a promising renewable energy substitute for diesel fuel due to several comparable and sustainable properties. However, approximately 95% of biodiesel is derived from edible oil crops, threatening the current food supplies. Therefore, the biodiesel production potential from inexpensive, non-edible, and non-conventional bioenergy crops, such as Jatropha (Jatropha curcas L.), has attracted the attention of many researchers, policymakers, and industries globally. Jatropha is considered to be the second-generation biofuel feedstocks for biodiesel production. However, sustainable biodiesel generation from J. curcas oil has not yet been attained, owing to different socio-economic, ecological, and technical factors. This study aimed to synthesize the information from the existing literature on the present status and to identify the knowledge gaps for future research on Jatropha by providing comprehensive information regarding its origin and distribution, morphology, phenology, and reproduction, genetic diversity, its productivity, oil content, and fatty acid composition, the methodology used for extracting biodiesel, and agronomic, economic, and environmental aspects of biodiesel production. The germplasm screening of J. curcas and the exploration of its adaptability and agronomic potential across diverse climates are highly desired to promote this crop as an alternative biofuel crop, particularly in arid and semi-arid regions. Moreover, future research should focus on developing, optimizing, and modernizing the technologies involving seed collection, the processing of seeds, oil extraction, and the production of biodiesel.

“…The response of plants to the salinity stress depends on a number of factors, like the concentration of salt in the soil, the time of exposure to the stressful condition, the age of the plant, the studied species and even the genotype or the variety (Silva et al 2015;Trebbi et al 2015;Laviola et al 2018), in a way that plants can be classified in more tolerant and more sensitive to salinity.…”
