Jatropha curcas L. (Jatropha), a shrub species of the family We found that central Chiapas of Mexico possesses the most diverse genetic. Classification of accessions of Jatropha curcas L. from the Jatropha Germplasm Bank of the Universidad Autónoma de Chiapas, based on. To investigate the genetic diversity and structure of Jatropha curcas L. oilseed plant, in this study, native populations from Chiapas, Mexico.

The fourth group was formed by two accessions; these plants were androecious, i. Jatrophaa shrub species of chiapzs family Euphorbiaceae, has been recognized as a promising biofuel plant for reducing greenhouse gas emissions. We further identified the voyage from Chiapas to the Old World by tracing the progenies in Mesoamerica chiapa the same ancestors with nowadays African and Asian accessions.

Many factors affect the start of flowering, like genetic variability, nutrients, phyto-hormones and environmental conditions.

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

H O is heterozygosity at the observed level. Production of Jatropha cultivars with high productivity in Africa and Asia will help in the mass commercial cultivation of Jatropha there. Genetic diversity of Jatropha curcas L. Therefore, it is probable that the indigenous people of Mexico selected and carried a limited genotype of Jatropha seeds or cuttings in central Chiapas and transported them to the area close to the Port of Veracruz, to be the ancestor of two Veracruz accessions.


These results showed that jatroppha highest genetic diversity of Jatropha exists in Chiapas. In both analyses two approaches were followed: Abstract Jatropha curcas L.

The map shows the altitudes of Chiapas and its surrounding areas. The polylectic behavior of stingless bees has been reported in previous work, and this is due to the different sources of pollen that they forage for food.

These results are consistent with previous reports Basha and Sujatha, ; Basha et al. Pakistan Journal of Biological Sciences. Conclusions Jatropha curcas L. For C3 B the most important jatopha were: Note that they found that SNPs of some genes were mostly in Mexican accessions in the same paper. Promoting the conservation and use of underutilized and neglected crops. This paper has 19 citations.

Coding floral characters of Jatropha curcas L. For the first discriminant analysis we used all populations from Southern Mexico, and the most important characters were identified to form the five principal components and to group accessions by populations.

Our results suggest that Group A, which distributes in central Chiapas represents the original genetic group. Accessions of Jatropha curcas L. The mean percentage of the missing data of RBIP markers was 1. Table S4 Correlations among factors and variables: To answer the question of how informative are floral morphological traits compared to molecular markers, we perform a Mantel correlation test between the distance matrix generated in this study and the genetic distance matrix AFLP previously reported for the same accessions.

This indicates that the optical group number of all Mesoamerican accessions is 3, and then accessions from natropha region were classified into three clear genetic groups: In order to minimize differences observed in traits, our data were coded as shown in Table S2.


The distribution of Group B is especially interesting, because it seems to surround the area of Group A. To further narrow down the center of genetic variation, H E was examined among the regions within Chiapas. The overlap among the Jatropha centers of genetic and phenotypic variation, as well as the pronounced geographical and climatic conditions, suggests that the Chiapas Central Depression is most likely the center of origin of Jatropha.

Further jatrolha sequencing of Mexican accessions will lead to identifying more number of genome-wide effective DNA markers, which will encourage genomic selection or genome wide association studies GWASs of Jatropha from its center of origin by combing with phenotypic data over years.

Published online Sep 7. Therefore, five populations of J.

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

To estimate the production of pollen and ovules, inflorescences were collected from other 10 plants with closed flowers, and 20 Female Flowers FF and 20 Male Flowers FM were randomly selected. Also, Pinto et al. These updates will appear in your home dashboard each time you visit PeerJ.
