Effective markers were selected from them based on clear polymorphisms and low number of null alleles. The fourth group was formed by two accessions; these plants were androecious, i.

In vitro mass multiplication of Jatropha Jatropha curcas L. Materials and Methods Biological material and study site We studied J.

Group I comprises all the African and Asian accessions and eight Mesoamerican accessions: Based in jatropga results, strategies to improve the productivity of J. Author information Article notes Copyright and License information Disclaimer.

Genetic Tracing of Jatropha curcas L. from Its Mesoamerican Origin to the World

A cluster analysis showed that the accessions from southern Mexico were grouped without showing any correlation with the geographical origin, while those accessions with atypical sexuality were grouped together. Dissimilarity dendrogram of 90 accessions of Jatropha curcas L.


It was probably because they used only 19 Mesoamerican Mexican accessions from limited collection sites. Similarly, accessions from the peripheral areas of Chiapas, Veracruz and Guatemala had the closest relationships with African and Asian accessions Supplementary Table 7. The study was conducted within the living fences of a farm plot at Soconusco, Chiapas, Southern Mexico Biomass Bioenergy 60 — Our results contribute to J.

However, of the 32 species of potential pollinators, not all were efficient as pollinators of J. Saving of carbon emissions depends on how biofuels are produced.

Discriminant analysis of Jatropha curcas landraces based on floral traits.

Reproductive biology of the biofuel plant Jatropha curcas in its center of origin [PeerJ]

In female flowers occasional curcws was found in the number of ovules two, three or four. Page, and Figtree 1. The red line represents a current road between Veracruz and Chiapas. The percentage of variation within groups was All of them were expected to have retrotransposed more recently than other members.

Regarding the phenomenon of apomixis, we found a very low rate 2. Conflict of Interest Statement The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.

In general, the Diptera had body sizes 7—14 mm and abundant pilosity on the body, but their behavior does not allow cataloging them as chiapae pollinators. For male and hermaphrodite jtaropha the number of filaments, anthers and pollen count was determined.


Genetic Diversity in Jatropha curcas Populations in the State of Chiapas , Mexico

Colors of branches denote groups formed. Population genetic software for teaching and research—an update Rod PeakallPeter E.

Pollen was quantified using a stereomicroscope and the average number of pollen grains was estimated per anther and per flower.

Additional Information and Declarations Competing Interests The authors declare there are no competing interests. Also, Pinto et al.

This strategy would be better than crossing among African and Asian Jatropha, or than just transplanting the Mexican one, because of the higher genetic diversity, heterozygosity and climate adaptability.

Analysis of seed phorbol-ester and curcin content together with genetic diversity in multiple provenances of Jatropha curcas L.

Our results showed that male flower diameter, female petal length, male nectary length are the most informative. The pattern showed that the female flowers are the first to open and this process continues for eight days.

Efficient pollinators of Jatropha curcas in the region of Soconusco, Southern Mexico. Molecular characterization and genetic diversity analysis of Jatropha curcas L.

Isidro Ovando-Medina conceived and designed the experiments, analyzed the data, wrote the paper, reviewed drafts of the paper.
