This breeding bottleneck represents a typical example of the founder effect and is probably the major cause of the failure of Jatropha breeding in African and Asian countries.

The campanian-maastrichtian rudist bivalves succession in the Chiapas Central Depression, Mexico. Presence of each of the eight retrotransposons was judged by presence of the amplified band using a FLK primer and a LTR primer, and in the case of full-length members, also by absence of the band using FLK primers at both sides of the retrotransposon.

Fences and medicines are the likely reasons why the Portuguese shipped the plant to Africa and Asia Sabandar et al. Accessions carrying all the eight retrotransposons.

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

Besides, the northern and southern parts of Chiapas have the humid tropical climate where the rainfall is plenty. The Spanish conquistadors normally did not enter the Chiapas Central Depression, where no mineral resources were expected to occur Ochiai, It was found that, under the study conditions, J.

Therefore, a male sterility mutation in hermaphrodites gynomonoecious would give way to females, and then the males curas appear from the suppression of female genes. We found significant correlation between data at the level of accessions.


The map shows the altitudes of Chiapas and its surrounding areas. Morphological and agronomical characterization of Jatropha curcas L.

Eigenvalues of the five main cyiapas, based on floral characters of accessions of Jatropha curcas L. Grouping of Jatropha curcas landraces based on discriminant analysis. In the case of J. The author found using cluster analysis, that the accessions are grouped without a geographical pattern.

Means to construct figure 2. Recently, Montes-Osorio et al. Genetic diversity analysis of Jatropha curcas L. In hermaphrodite flowers Fig. All data analyses were performed based on the genotype data matrix.

A neighbor-joining tree of non-admixed Mesoamerican accessions and African and Asian accessions. Physic Nut Jatropha curcas L. Excel archive with the average of data. Support Center Support Center. Native stingless bees S. Common use cases Typos, corrections needed, missing information, abuse, etc Our promise PeerJ promises to address all issues as quickly and professionally as possible. The highest genetic variation and the lowest F IS among the three groups were observed in Group A Supplementary Table 5which was as expected from the results of the previous section.

These data agree with those previously reported by other authors Heller, ; Toral et al. The low genetic diversity of African and Asian accessions has limited the potential for successful breeding by using local resources. Interestingly, in Soconusco, the southernmost peripheral region of Chiapas, F IS was the lowest, and in Sierra, one of the central regions, locating near to Soconusco, F IS was the second lowest.

To improve the traits in the breeding goal of Jatropha in Asia and Africa, it is of great significance not only to identify diverse genetic resources but also to unveil the ancestral genotype of African and Asian Jatropha when shipped from Mesoamerica. In addition, accumulation of mildly deleterious genes exhibited in the homozygous state by inbreeding might show inbreeding depression. The presence of trichomes was evaluated according to the following scale: 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.


Over SSR markers were developed by designing primer pairs surrounding SSR sequences identified by the genomic database of Asian accessions based on our whole genome sequencing project Sato et al. There were no fruits in the months from December to March. Therefore, this study aimed a to describe J.

The absence of genetically similar accessions between central Chiapas and the port of Veracruz excludes a gradual natural expansion by seeds and favors the human-mediated spread of Jatropha from central Chiapas to the Port of Veracruz. Based in our results, strategies to improve the productivity of J.

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

Enzymatic transesterification of Jatropha oil. 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. Genetic homogeneity in Jatropha curcas L. The red line represents a current road between Veracruz and Chiapas. This indicates that the optical group number of all Mesoamerican accessions is 3, jatrophq then accessions from each region were classified into three clear genetic groups:
