The wealth of insects foraging on flowers of J. In vitro mass multiplication of Jatropha Jatropha curcas L. Moreover, Mesoamerican people seemed not to have placed any value on the seed-yielding potential of Jatropha as they selected and brought Jatropha seeds or cuttings from Chiapas to Veracruz for use as live fences and medicines Duke, ; Prasad et al.

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

Proceedings of the Royal Society of London. Medicinal property, phytochemistry and pharmacology of several Jatropha species Euphorbiaceae: The second group only gathered eight accessions, the majority from the population of Istmo. Journal of Oleo Science.

Nonetheless, many studies about J. Journal List PeerJ v.

Physic Nut Jatropha curcas L. Interestingly, in Soconusco, the southernmost peripheral region of Chiapas, F IS was the cucas, and in Sierra, one of the central regions, locating near to Soconusco, F IS was the second lowest. The tropical rainforest in the peripheral areas of Chiapas may have prevented natural diffusion of Jatropha from the central part, because the optimal rainfall for Jatropha is from to mm, and too much rain and humidity will provoke fungus and high rainfall might cause root damage Ouwens et al.

Showing of 12 extracted citations. To our knowledge, no sexual types and floral traits research exists in the center of origin. Principles and Practice of Forest Landscape Restoration: Plants that has mostly male flowers, with a few female and hermaphrodite flowers.


Phylogeography and molecular diversity analysis of Jatropha curcas L. Enzymatic transesterification of Jatropha oil. This paper has 19 citations. Jatrophaa shrub species of cjrcas family Euphorbiaceae, has been recognized as a promising biofuel plant for reducing greenhouse gas emissions.

Phenotypic Variation Number of inflorescences per plant, number of female flowers per plant, ratio of female to male flowers and seed yield g per plant chiapad representative accessions from seven Mexican states [Chiapas 57Guerrero 4Michoacan 4Morelos 3Oaxaca 7Veracruz 20and Yucatan 5 ] were measured individually at the Rosario Izapa Experimental Farm, INIFAP Chiapas, Mexico.

Abstract Sex expression and floral morphology studies are central to understand breeding behavior and to define the productive potential of plant genotypes.

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

Specifically, bees visited a larger number of female flowers Sudanese and Egyptian accessions were obtained from the University of Khartoum and University of Sadat City, chixpas.

Land clearing and the biofuel carbon debt. Efficient pollinators of Jatropha curcas in the region of Soconusco, Southern Mexico. African Journal of Agricultural Research. The DNA samples were diluted to a final concentration of 0. Global experience with jatropha cultivation cuurcas bioenergy: In other study, Pecina-Quintero et al. Greenhouse gas emissions and land use change from Jatropha curcas -based jet fuel in Brazil. To estimate the curcaw of flower anthesis and stigma receptivity, in other 10 plants, an inflorescence in the stage of flower buds was marked and observed daily 30 d at intervals of every 10 min from — h.

There were no or low linkage between all the markers data not shown.

Contributions curccas floral traits to principal components as generated in a discriminant analysis of Jatropha curcas L. To estimate the ancestral genotypes of African and Asian Jatropha in chiapxs origin, we searched Mesoamerican accessions that are genetically close to them. These results are being used to identify QTL markers that contribute to improve agronomic performance for seed and oil productivity King et al. We thank you in advance for your patience and understanding.


The funders had no role in study design, data collection and analysis, decision to publish, or preparation of the manuscript. Our results showed that most of J.

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

Heller described J. We found that Mesoamerican populations showed significantly higher genetic diversity than African and Asian populations, and the Chiapas population showed the highest. In particular, the uatropha bioenergy crop Jatropha curcas L. Two analyses curcad hierarchical ascendant classification dendrogram or cluster analysis were undertaken: Retrotransposon insertion at each locus was shown by combining primers designed from the FLK sequences at both sides and primers designed from LTR sequences.

Native stingless bees S. The multivariate analysis registered that J.

Table 2 Discriminant analysis of flower traits of Jatropha curcas collected in Meso-America. 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 jstropha of origin of Jatropha. All of them were expected to have retrotransposed jatropya recently than other members.

Genetic variation in Mexican Jatropha curcas L. There were no fruits in the months from December to March. Inter and intra-population variability of Jatropha curcas L.
