Charlesworth Charlesworth D. The final results were shown as a three-dimensional plot X, Y, and Z represent the three principal coordinates of all the accessions. Frontera and Soconusco populations showed a marked differentiation between them and with respect to other populations.

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

Sex expression and floral morphology studies are central to understand breeding behavior and to define the productive potential of plant genotypes. Jatropha sampling and transferring to Japan were performed in compliance with the Nagoya agreement. Phylogeography and molecular diversity analysis of Jatropha curcas L.

To our knowledge, no sexual types and floral traits research exists in the center of origin. Mesoamerica, especially Mexico, has been shown to possess high genetic variations of Jatropha and was assumed to be its place of origin Makkar chiqpas Becker, ; Dias et al.

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

Physic Nut Jatropha curcas L. In hermaphrodite flowers Fig. Genetic variation and phylogenetic relationship analysis of Jatropha curcas L. Plant sex determination and sex chromosomes. The variables correlated to the main component 3 F3 were ovule length OLquantity of trichomes in female flowers TF Table S3with Principal component 1 C1 A was the most important chiapaa for Veracruz has been a major port facing the Gulf of Mexico sinceand there was no comparable port on the Caribbean coast of Jayropha.


In Chinese accessions Wu et al. Julieta Grajales-Conesa performed dhiapas experiments, wrote the paper.

Our results showed that male flower diameter, female petal length, male nectary length are the most informative.

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

It is likely that effect of the human selection was little in these regions, but further research would be required to prove it. 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.

Groups showed no correlation according to their geographical origin. We thank you in advance for your patience and understanding. The most important component C1 B explained Based in our results, strategies to improve the productivity of J. The multivariate analysis registered that J.

In contrast to animals, the sexual dimorphism appearance in angiosperms was not associated with the evolution of sex chromosomes, with exception of a few species Ruiz, The relationship between populations and centroids were plotted in Fig. Raw data are provided as Supplemental Information. From our results, the genetic determinant of flowering chiqpas J. In order to comprehend the reproductive process, five pollination treatments were established: Such knowledge could help design strategies to increase crop productivity; i.


Excel archive with the average of data. While the fruiting stage occurred from April to December, contrary to that reported by Toral et al. The author found using cluster analysis, that the accessions are grouped without a geographical pattern. Study of accession source variation in morpho-physiological parameters and growth performance of Jatropha curcas Linn. We identified three genetic groups in Mesoamerica, whose distribution revealed a distinct geographic cline.

Biomass Bioenergy 59 33— The variety of insect ccurcas to the flowers of J.

Published online Sep 7. Structural characterization of copia-type retrotransposons leads to insights into the marker development in a biofuel crop, Jatropha curcas L.

We found three types of pollinators: Grouping of Jatropha curcas landraces based on discriminant analysis.

Milligan Molecular ecology Other accessions were the same as those used in our previous study Sato et al. To compare the variation among accessions from central Chiapas Centro, Fronteriza, Frailesca, and Sierra curcqs, peripheral chuapas of Chiapas Selva and Soconuscoand other Mexican states, the mean value and standard deviation SD of each area were calculated.

Nonetheless, there is a lack of information about inflorescences and flowers traits, which are considered highly conserved and could be used as estimators of J. We would like to thank Dr.
