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

The remaining insects were considered pillagers or nectar robbers Table 1. Our promise PeerJ promises to address all issues as quickly and professionally as possible. For all the flowers we determined the number of sepals, petals and nectaries.

Slight differences between expected and observed heterozygosity H E versus H O were observed among the accessions from central Chiapas, whereas large differences between these statistics were detected among the accessions from the peripheral areas of Chiapas, other Mexican states, and Guatemala Figures 1B,C. The variety of insect visitors to the flowers of J. Comparative study of biochemical traits and molecular markers for assessment of genetic relationships between Jatropha curcas L.

Graph chiapaas centroids of the eight populations of Jatropha curcas L.

We found genetic grouping Groups A, B, and C that correlated with geographic location in Mesoamerica, which has not been reported previously. Further genomic 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.


Since then, seed productivity did not have a high priority in most part of Africa and Asia until recently. Additional Information and Declarations Competing Interests The authors declare there are no competing interests. Common use cases Typos, corrections needed, missing information, abuse, etc Our promise PeerJ promises to address all issues as quickly and professionally as possible. Typo Missing or incorrect metadata Quality: 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.

PCoA analysis also revealed a close relationship between these seven accessions and African and Asian ones Supplementary Figure 4. 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.

In fact, one of the Veracruz accessions No. The campanian-maastrichtian rudist bivalves succession in the Chiapas Central Depression, Mexico. According to these observations, it was determined that an efficient pollinator for J.

They were observed simultaneously visiting female flowers for nectar during the period of maximum stigma receptivity facilitating xenogamy and geitonogamy, whereby they were classified as efficient pollinators. Accuracy of estimated phylogenetic trees from molecular data. It was found that, under the study conditions, J. Subsequent to that, there were three periods of peak fruiting in the months of May, June and October.

All of them were expected to have retrotransposed more recently than other members. Some aspects of the floral biology of J.

Potential pollinators of Jatropha curcas in the region of Soconusco, Sourthern Mexico. Characteristics of physic nut, Jatropha curcas L. Genetic diversity and structure of Jatropha curcas L.

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

It is sandwiched by the northern highlands, central plateau and the southern Sierra Madre Mountains. According to the results, number of retrotransposons present in each accession was counted. Finally, we propose strategies to improve African and Asian Jatropha, in order to increase the phenotypic performance including productivity, which will lead us to relieve from the climate change by mass production of the biofuel.
