The last few years have seen a significant increase in the number of large-scale sequencing projects generating whole genome databases. These sequence databases can be surveyed (genome sequence survey) for tandem repeats as an alternative means to develop microsatellites for monitoring and selecting natural populations and cultivars of Jatropha curcas. A total of 100 tandem repeats were reveale...

Developing a protocol for somatic embryogenesis (SE) adult mother plants of Jatropha curcas, aids to overcome problems such as harvesting time and an uneven yield, providing the opportunity propagate proven elite genotypes. Until now, several authors have achieved SE in J. curcas using different explants, however, none these protocols been used plant material. Furthermore, challenge overcoming ...

Many medicinal plants have been reported to exhibit protective effects against many physiological diseases as a result of their phytochemical components which are effective antioxidants. This study was aimed at comparing the phenolic and flavonoids contents, antioxidant cytotoxic activities methanol extract Jatropha curcas seeds leaves. The cytotoxicity level J. assessed using brine shrimp leth...

molecular characterization of 19 jatropha accessions that included 15 accessions of j.curcas and 4 different species was carried out using 3 different markers systems. highest polymorphism (96.67%) was recorded by rapd followed by damd (91.02%) and issr (90%). polymorphism information content (pic) was higher for damd (0.873) and almost equal for rapd (0.863) and issr (0.862) markers, whereas r...

Jatropha curcas is a woody-shrub species of the Euphorbiaceae family that widely distributed in tropical and subtropical areas. The great interest its cultivation lies potential for achieving elevated yields high-quality oil. Another characteristic makes J. promising ability to produce green energy even high-salinity soils. For commercial be considered effectively competent withstand these cond...

Jatropha curcas L. (Euphorbiaceae) is a plant species widely present in tropical and subtropical regions that have been studied mainly for its potential biofuel production; it also known toxic substances. To explore use as an insecticide, we the effect of seed extract from green fruit oils mature dried J. on aphid Myzus persicae (Hemiptera: Aphididae). Seven concentrations extracts different ma...

Various government agencies around the world have proposed vegetable oils and their conversion to biodiesel as a renewable alternative to fossil fuels. Due to its adaptability to marginal soils and environments, the cultivation of Jatropha curcas is frequently mentioned as the best option for producing biodiesel. In the present work the current situation of proven and potential reserves of foss...

An environmentally benign process was developed for the transesterification of Jatropha curcas L. seed oil with methanol using artificial zeolites loaded with potassium acetate as a heterogeneous catalyst. After calcination for 5 h at 823 K, the catalyst loaded with 47 wt.% CH3COOK exhibited the highest efficiency and best catalytic activity. The easily prepared catalysts were characterized by ...

In this work, we studied the main characteristics of flowering, reproductive system and diversity of pollinators for the biofuel plant Jatropha curcas (L.) in a site of tropical southeastern Mexico, within its center of origin. The plants were monoecious with inflorescences of unisexual flowers. The male flowers produced from 3062-5016 pollen grains (266-647 per anther). The plants produced fru...

Genetic variation in the genome of a given species is the basis for natural selection and genetic improvement through selective breeding. We applied 29 microsatellites located on 11 linkage groups to study genetic variation in 276 accessions of J. curcas collected from nine locations in five countries in South America, Asia and Africa to initiate a breeding program. To our surprise, we did not ...
