“…Namun, masih terdapat kendala dalam budi daya tanaman ini karena bahan tanam unggulnya masih belum banyak diketahui dan kurangnya informasi teknik budi daya. Fakta menunjukkan bahwa jarak pagar merupakan tanaman yang masih belum didomestikasi secara penuh mengingat sebagian besar aksesi jarak pagar di dunia masih toksik (Montes et al 2014) sehingga bungkil bijinya yang kaya protein tidak dapat langsung digunakan sebagai pakan ternak. Berbagai usaha ekstra masih diperlukan untuk dapat menghasilkan bahan tanaman unggul yang dapat dibudidayakan secara ekonomis dengan produktivitas minyak tinggi dan kompetitif untuk digunakan sebagai bahan baku pembuatan biodiesel.…”

“…Peranan bioteknologi (genomika, rekayasa genetika, dan perbanyakan in vitro) dalam memecahkan masalah bahan tanaman unggul jarak pagar sangat jelas dalam mempercepat siklus pemuliaan, perbanyakan klon unggul secara massal, transformasi genetik, dan pemanfaatan diversitas genetik secara komprehensif pada program pemuliaan sehingga diperoleh varietas unggul dengan produktivitas dan nilai tambah tinggi, ekonomis untuk dibudidayakan dan minyaknya sesuai sebagai bahan baku biodiesel. Perkembangan teknologi terkini yang meliputi: studi genetika, genomika, perbanyakan in vitro, dan transformasi genetik tanaman jarak pagar akhir-akhir ini berkembang cukup pesat (Biabani et al 2012;Montes et al 2014;Sujatha et al 2008;Wu et al 2015). Tujuan tulisan ini ialah mengulas tentang pendekatan bioteknologi dan genomika untuk perbaikan genetik tanaman jarak pagar.…”

“…Saat ini, setidaknya ada dua germplasm pool jarak pagar yang telah dilaporkan, yaitu germplasm pool dengan biji nontoksik yang tidak mengandung senyawa phorbol ester (PE) dan germplasm pool dengan biji toksik yang mengandung PE (Montes et al 2014). Aksesi SDG nontoksik ini berasal dari Meksiko yang merupakan sumber daya pemuliaan penting untuk perakitan varietas yang produk sampingnya diarahkan sebagai penghasil bungkil jarak pagar untuk pakan ternak.…”

“…Aplikasi bioteknologi akan memfasilitasi percepatan peningkatan diversitas genetik dan perakitan bahan tanaman unggul jarak pagar. Karena diversitas genetik antar-germplasm pool toksik dan nontoksik yang relatif tinggi (Montes et al 2014), Indonesia sangat perlu memiliki germplasm pool biji nontoksik asal Meksiko tersebut untuk meningkatkan potensi heterosis karakter daya hasil biji dan karakter agronomis penting lainnya untuk meningkatkan potensi keberhasilan program pemuliaan jarak pagar nasional ke depan.…”

Physic nut (Jatropha curcas L.) is an oil-bearing crop whose oil can be used as diesel substitution. This crop can be grown at suboptimal soils and thus attracts many people to explore its potential as a biorenewable energy crop. Many constrains, however, are faced by this crop. From plant material and cultivation aspects, not much information has yet been known regarding this crop. In addition, people still view physic nut as an incomplete domesticated crop as indicated by the fact that many J. curcas accessions of the world still have toxic in their seeds causing the protein-rich seeds can not directly be used as animal feed. J. curcas demonstrates continuous fruiting habit during its fruiting season and hence no uniform fruit maturity causing expensive harvesting cost. The female and male flower ratio is low causing lower seed productivity. J. curcas oil is relatively rich with poly unsaturated fatty acids that need to be decreased to improve diesel quality. Genomic knowledge to understand J. curcas genes and function is critical to manipulate J. curcas genetics systematically. Genetic transformation technology is potentially applied for better plant architecture, improvement of agronomically important characters, seed and oil yield, and quality traits. The objective of this manuscript was to review biotechnology and genomic approaches for genetic improvement of J. curcas plant materials. The biotechnological method application should expedite J. curcas breeding programs. With superior planting materials, the J. curcas should be able to be cultivated economically and resulting better J. curcas oil suitable for biodiesel industry.Keywords: Jatropha curcas, genomics, gene and QTL, genetic transformation, marker-assisted breeding. ABSTRAKJarak pagar (Jatropha curcas L.) merupakan tanaman penghasil minyak nabati yang dapat digunakan sebagai pengganti minyak diesel. Tanaman yang dapat tumbuh pada kondisi lahan kurang subur ini menarik minat banyak pihak untuk mengekplorasi potensinya sebagai tanaman sumber energi yang ramah lingkungan. Namun, masih banyak kendala yang dihadapi dalam pembudidayaannya supaya dapat diusahakan secara ekonomis. Dari aspek bahan tanaman dan budi daya, saat ini tanaman jarak pagar masih belum banyak diketahui. Bahkan, jarak pagar masih dianggap sebagai tanaman yang belum didomestikasikan secara penuh seperti ditunjukkan oleh fakta bahwa sebagian besar genotipe jarak pagar di dunia bijinya toksik sehingga ampas bijinya yang kaya protein tidak dapat langsung digunakan sebagai pakan ternak. Kematangan buah tanaman ini tidak serempak yang menyebabkan biaya panen tinggi. Rasio bunga betina dan bunga jantan yang rendah menyebabkan produktivitas bijinya rendah. Biji jarak pagar mengandung asam lemak poli tidak jenuh yang konsentrasinya perlu diturunkan untuk meningkatkan mutu minyak diesel. Pengetahuan genomika memungkinkan untuk mengetahui komposisi genom, komposisi dan fungsi gen, dan pemetaan genetik (gen/QTL) unggul jarak pagar. Pemahaman ini diperlukan agar genetika tanaman jarak...

“…In jatropha, there exist two distant genetic pools, i.e., the pool A (phorbol ester absent) and the pool B (phorbol ester present) [8]. The germplasm from pool A originates from Central America and Mexico only, whereas the germplasm from pool B can be found globally.…”

Jatropha curcas L. (jatropha) is an undomesticated plant with a high potential for sustainable production of biofuels in the tropics and subtropics. Oil content, seed mass, kernel mass, and the ratio of kernel to seed mass are important traits for breeding. These traits could potentially be improved by exploitation of parental effects. Besides, parental effects could be used to separate self-from cross-fertilized seeds and increase the efficiency of hybrid seed production. The main goal of this study was to assess the variation of quantitative seed traits (oil content, seed mass, kernel mass, and ratio of kernel to seed mass) in a panel of self-and cross-fertilized seeds from a genetically diverse germplasm. We analyzed a set of 31 genotypes (12 self-and 19 cross-fertilized genotypes) originated by combination of parental components from 2 different genetic pools (pool A: phorbol ester absence; pool B: phorbol ester present). We found strong significant effects of parental components and genetic pools on most seeds traits. Although the variation in oil content among single seeds was very large, some specific combinations of parental components showed promise to be exploited for rapid and automatized identification and classification of self-and cross-fertilized seeds. We conclude that parental effects need to be considered for breeding and cultivar production.

Jatropha curcas L. (Euphorbiaceae) is a shrub native to Mexico and Central America, which produces seeds with a high oil content that can be converted to biodiesel. The genetic diversity of this plant has been widely studied, but it is not known whether the diversity of the seed oil chemical composition correlates with neutral genetic diversity. The total seed oil content, the diversity of profiles of fatty acids and phorbol esters were quantified, also, the genetic diversity obtained from simple sequence repeats was analyzed in native populations of J. curcas in Mexico. Using the fatty acids profiles, a discriminant analysis recognized three groups of individuals according to geographical origin. Bayesian assignment analysis revealed two genetic groups, while the genetic structure of the populations could not be explained by isolation-by-distance. Genetic and fatty acid profile data were not correlated based on Mantel test. Also, phorbol ester content and genetic diversity were not associated. Multiple linear regression analysis showed that total oil content was associated with altitude and seasonality of temperature. The content of unsaturated fatty acids was associated with altitude. Therefore, the cultivation planning of J. curcas should take into account chemical variation related to environmental factors.
