“…Jatropha curcas L. (Euphorbiaceae) is a perennial tree, monoecious with unisexual flowers (Montes and Melchinger, 2016). Probably native to Mexico (Pecina-Quintero et al, 2014) this species occurs in tropical and subtropical regions of the world, and it is considered one of the most promising oilseeds for biodiesel production due to the high oil content of oilseeds, reaching 40 to 50% (Subramanian et al, 2005).…”

ABSTRACT. Jatropha curcas L. is a highly promising oilseed for sustainable production of biofuels and bio-kerosene due to its high oil content and excellent quality. However, it is a perennial and incipiently domesticated species with none stable cultivar created until now despite genetic breeding programs in progress in several countries. Knowledge of the genetic structure and diversity of the species is a necessary step for breeding programs. The molecular marker can be used as a tool for speed up the process. This study was carried out to assess genetic diversity of a germplasm bank represented by J. curcas accessions from different provenance beside interspecific hybrid and backcrosses generated by IAC breeding programs using inter-simple sequence repeat markers. The molecular study revealed 271 bands of which 98.9% were polymorphic with an average of 22.7 polymorphic bands per primer. Genetic diversity of the germplasm evaluated was slightly higher than other germplasm around the world and ranged from 0.55 to 0.86 with an average of 0.59 (Jaccard index). Cluster analysis (UPGMA) revealed no clear grouping as to the geographical origin of accessions, consistent with genetic structure analysis using the Structure software. For diversity analysis between groups, accessions were divided into eight groups by origin. Nei's genetic distance between groups was 0.14. The results showed the importance of Mexican accessions, congeneric wild species, and interspecific hybrids for conservation and development of new genotypes in breeding programs.

“…The yield ranges from 0.3 to 3000 kg seeds/ha. It is adapted to different environmental conditions, including low rainfall and lowfertility soil, and does not compete with food crops (Montes and Melchinger, 2016).…”

“…However, domestication of J. curcas under various climatic conditions is not fully documented. It is suggested that utraditional scientific methods and novel technologies should be applied to this plant in order to accelerate its productivity (Montes & Melchinger, 2016). In our previously published work, we found that laser treatment resulted in a significant increase in the expression of Rubisco large subunit (RbcL) above the basal level in soybean seedlings (Khalifa & Ghandoor, 2011) and J. curcas (Khalifa & Elsherief, 2013).…”

JATROPHA curcas is a promising plant for biodiesel production. One tentative way to increase oil production is using non traditional physical methods such as laser. It had been shown before that laser could enhance plant growth and development as general. In this study, the DNA was extracted from leaves of plants grown from seeds collected from different regions in Egypt and tested using PCR to confirm their homogenousity. Then, the fully expanded leaves of Jatropha (6-week-old plants) were exposed to a dose equaling 300 mJ cm -2 Helium-Neon (He-Ne) laser. The effect of the administered dose on the photosynthetic pigment expression, chloroplast biogenesis and total amino acid biosynthesis were evaluated after 0, 1 and 24 h post irradiation. Laser treatment in this work did enhance all the previousely mentioned parametrs as will be discussed further in relation to the possibility of using laser as a novel protocol to enhance field crop plants as general.

“…Jatropha curcas L. (jatropha, 2n=22)and Ricinus communis L.(castor bean, 2n=20), both of the family Euphorbiaceae, are non-edible oilseed crops for biofuel/biodiesel production (Berchmans and Hirata 2008, Berman et al 2011, Spinelli et al 2014, Kanti et al 2015, Montes and Melchinger 2016. The lack of adequate genetic variation has limited jatropha improvement (Allan et al 2008, Sun et al 2008, Trebbi et al 2015.One effective way to create genetic variability and incorporate desirable traits is by wide hybridization.The study addressed a combination of desirable traits of the two genera related to seed yield, oil content and quality, and to synchronous maturity.…”
