Genome size, base composition and karyotype of Jatropha curcas L., an important biofuel plant

Genetic similarity of Jatropha curcas accessions based on AFLP markers

“…Dahmer et al (2009) found chromosome stability in five J. curcas populations (2n = 2x = 22). This led the authors to conclude that the species is diploid, in contrast to reports suggesting autotetraploid species (Carvalho et al 2008), and that the chromosomal stability is an advantage due to regular meiosis, to perform manual crosses between different accessions of the species.…”

Physical Mapping of Ribosomal DNA Genes on <i>Jatropha curcas</i> Chromosomes by Multicolor FISH

“…The size of these chromosomes is reported to range from 1.24 to 1.71 mm, with the nuclear genome size close to 430Mb. 5 of them are metacentric and 6 are submetacentric (Carvalho et al 2008).…”

Innovative Biological Solutions to Challenges in Sustainable Biofuels Production

“…Information on genetic diversity in Jatropha is still limited since most studies have concentrated on accessions from India where the shrub was brought by the Portuguese. Due to its relatively small genome (2C value of 0.85 pg, in the same size range as that of rice) (Carvalho et al, 2008), Jatropha could become a model woody crop for biodiesel production. Genetic and genomic resources for this emerging biofuels crop are becoming available including a transformation system (Li et al, 2008), a 100x coverage of the J. curcas genome sequence (http://www.lifetechnologies.com/news-gallery/pressreleases/2010/life-techologies-ad-sg-biofuels-complete-sequece-of-jatropha-geo.html), and a growing library of expressed sequence tags (ESTs) from developing and germinating Jatropha seeds (Costa et al, 2010).…”
