Background: Jatropha curcas, a tropical shrub, is a promising biofuel crop, which produces seeds with a high content of oil and protein. To better understand the development of its seeds to improve Jatropha`s agronomic performance, a two-step approach was performed: 1) generation of the entire transcriptome of six different maturation stages of J. curcas seeds using 454-Roche sequencing of a cDNA library, 2) comparison of transcriptional expression levels in six different developmental stages of seeds using a custom Agilent 8x60K oligonucleotide microarray. Results: A total of 793,875 high-quality reads were assembled into 19,841 unique full-length contigs, of which 13,705 could be annotated with Gene Ontology (GO) terms. Microarray data analysis identified 9,111 probes (out of 57,842 probes), which were differentially expressed between the six developmental stages. The expression results were validated for 70 randomly selected putative genes. Result from cluster analyses showed that transcripts related to sucrose, fatty acid, flavonoid, phenylpropanoid, lignin, hormone biosynthesis were over-represented in the early stage, while lipid storage, seed dormancy and maturation in the late stage. Generally, the expression of the most over-represented transcripts decrease in the last stage of seed maturation. Further, expression analyses of different maturation stages of J. curcas seed showed that most changes in transcript abundance occurred between the two last stages, suggesting that the timing of metabolic pathways during seed maturation in J. curcas is in late stages. The co-expression result showed a high degree of connectivity between genes that play essential role in fatty acid biosynthesis and nutrient mobilization. Furthermore, seed development and hormone pathways are significantly well connected. Conclusion: The obtained results revealed DESs regulating important pathways related to seed maturation, which could contribute to understanding the complex regulatory network during seed development. This study provides detailed information on transcription changes during J. curcas seed development and provides a starting point for a genomic survey of seed quality traits. The current results highlighted specific genes and processes relevant to the molecular mechanisms involved in Jatropha seed development, and it is anticipated that this data can be delivered to other Euphorbiaceae species of economic value.

“…In general, it is recommended to apply doses of fertilizers recommended for other crops, and it is necessary to test recommendations based on results of soil analysis, which can widely vary according to the studied environment. One of the promising alternatives for jatropha fertilization is the use of organic material, like cattle manure (Sop et al, 2011;Schulz et al, 2012) and oilseed cakes , or through the application of mineral nitrogen (Prates et al, 2011), phosphate (Carvalho et al, 2013) and potassium (Freiberg et al, 2014) fertilizers, which can be used individually or associated with organic fertilizers (Hussein et al, 2012). The limitations for the availability of nutrients, such as N and P, in the beginning of the vegetative growth can result in restrictions for the formation of the root system and shoots (Silva et al, 2009), as well as for the crop reproductive stage (Pereira et al, 2011).…”

“…On the other hand, Prates et al (2012) recommend the use of 11 t ha -1 of sewage sludge as the source of organic matter in order to obtain well-nurtured and productive plants. According to Sop et al (2011), the application of 500 g hole -1 of cattle manure is an excellent recommendation of fertilization for jatropha cultivated under rainfed conditions. Hussein et al (2012) recommend the dose of 5 kg plant -1 of cattle manure in order to obtain vigorous and productive plants.…”

Jatropha (Jatropha curcas L.) is a perennial species that requires expressive amounts of nutrients in order to produce satisfactorily. An experiment was conducted using pots, arranged in a randomized block design, with four replicates and one plant per plot, in order to evaluate different fertilization recommendations (phosphate fertilizer and cattle manure) based on soil analysis. The treatments consisted of a 4 x 4 factorial scheme, which represented 4 recommendations of organic fertilization [absence of organic fertilization (0 t ha -1 ), recommended dose (4 t ha -1 ), 1.5 times the recommended dose (6 t ha -1 ) and 2 times the recommended dose (8 t ha -1 )] and 4 recommendations of phosphate fertilization [absence of phosphate fertilization (0 kg ha -1 ), recommended dose (90 kg ha -1 ), 1.5 times the recommended dose (135 kg ha -1 ) and 2 times the recommended dose (180 kg ha -1 ). One hundred and eighty days after seedlings were transplanted to the pots, growth variables and production components were measured. Plant height, number of branches, stem diameter, leaf area, number of inflorescences, number of fruits, number of bunches, number of fruits per bunch, mass of fruits, number of seeds per fruit, number of seeds per plant and total mass of seeds per plant were influenced by the fertilization recommendations. The recommendation of organic and phosphate fertilization suggested by the laboratory of soil analysis (4 t ha -1 of organic matter and 90 kg ha -1 of phosphorus) was insufficient to obtain productive plants. The isolated use of organic matter in fertilization of jatropha promotes positive effects on growth variables and production components. The application of 1.5 the dose of organic matter recommended by the laboratory of soil analysis, corresponding to 6 t ha -1 of cattle manure, isolated, or associated with 135 kg ha -1 of P, is sufficient to supply the nutritional demand for N and P in the first cultivation cycle. Phosphate fertilization associated with organic fertilization significantly influenced plant height, number of branches, stem diameter, leaf area, number of seeds per plant and total mass of seeds of jatropha plants.Keywords: Jatropha curcas L.; fertilization recommendation; cattle manure Abbreviations: S_Sum of bases; T_Cation exchange capacity; V_Saturation of bases; OM_Organic matter; DAT_Days after transplant ; LA_Leaf area , Σ_sum of leaf area; L_Midrib lenght; W_leaf width; PH_ Plant height , NLB_Number of leaves per plant, NBP_Number of branches per plant , SD_Stem diameter; LA_Leaf area (%); ns_Not significant; DF_Degree of freedom; C.V_Coefficient of variation; NIP_Number of inflorescences per plant; NFP_Number of fruits per plant; NBP_Number of bunches per plant; NFB_Number of fruits per bunch; MMF_Mean mass of fruits; NSF_Number of seeds per fruit: NSP_Number of seeds per plant; MSP_Mass of seeds per plant.

“…Given the suitability of Jatropha curcas L. for cultivation on marginal land under dry conditions (Francis et al, 2005;Jongschaap et al, 2007;Reubens et al, 2011;Contran et al, 2013), 11% of semi-arid areas in Burkina Faso (Wicke et al, 2011) and more than one third of the total land in Africa (Cai et al, 2011) could be available for its production. J. curcas has been cultivated in Burkina Faso since 2007, yet field assessments of tree growth and biomass, particularly fruit production remain localized and scarce (Sop et al, 2012).…”
