A revision of Jatropha (Euphorbiaceae) in Malesia Naturalis
Welzen, P.C. van; Sweet, F.S.T.; Fernández-Casas, F.J..
Jatropha, a widespread, species rich genus, ranges from the Americas and Caribbean to Africa and India. In Malesia five species occur, all of which were introduced and originated in Central and South America. The five species are revised and an identification key, nomenclature, descriptions, distributions, ecology, vernacular names, uses and notes are provided. Special attention is given to the uses of J. curcas, because it is steadily gaining popularity as a potential biofuel plant and, because of that, is being cultivated more often.

Branching, flowering and fruiting of Jatropha curcas treated with ethephon or benzyladenine and gibberellins Anais da ABC (AABC)
Costa,Anne P.; Vendrame,Wagner; Nietsche,Sílvia; Crane,Jonathan; Moore,Kimberly; Schaffer,Bruce.
Jatropha curcas L. has been identified for biofuel production but it presents limited commercial yields due to limited branching and a lack of yield uniformity. The objective of this study was to evaluate the effects of single application of ethephon or a combination of 6-benzyladenine (BA) with gibberellic acid isomers A4 and A7 (GA4+7) on branch induction, flowering and fruit production in jatropha plants with and without leaves. Plants with and without leaves showed differences for growth and reproductive variables. For all variables except inflorescence set, there were no significant statistical interactions between the presence of leaves and plant growth regulators concentration. The total number of flowers per inflorescence was reduced as ethephon...

Cnidoscolus (Euphorbiaceae) escaped in Malesia? Naturalis
Welzen, P.C. van; Fernández-Casas, F.J..
The genus Cnidoscolus, a species rich genus in the Americas, has been introduced in the Philippines. A cultivar of Cnidoscolus aconitifolius is used as vegetable and has been collected from gardens in Manila and Pasay City and two times near Cebu City. It cannot be excluded that it has escaped cultivation there, but the species does not appear to be invasive.

Economic Benefits and Costs of Jatropha Plantation in North-East India AgEcon
Goswami, Kishor; Saikia, Jitu; Choudhury, Hari Kanta.
Energy security, emissions control and environmental concerns are some of the issues that drive India to search for bio-fuels in general and bio-diesel in particular as an alternative source of energy. The inception of National Biofuel Mission in 2003 has resulted in expansion of jatropha plantations in different states of the country. In North-East India, jatropha plantation was started in 2007, mostly at small farmers’ level with direct and indirect initiatives of the government and the private sector. However, adoption and expansion of jatropha plantation in the rural areas largely depend on profitability from such plantations at farmers’ level. The present study has assessed the profitability of jatropha plantation in four states of North-East India,...

Increasing selection gain and accuracy of harvest prediction models in Jatropha through genome-wide selection. Repositório Alice
SANTOS, A. dos; RODRIGUES, E. V.; LAVIOLA, B. G.; TEODORO, L. P. R.; TEODORO, P. E.; BHERING, L. L..
Abstract: Genome-wide selection (GWS) has been becoming an essential tool in the genetic breeding of long-life species, as it increases the gain per time unit. This study had a hypothesis that GWS is a tool that can decrease the breeding cycle in Jatropha. Our objective was to compare GWS with phenotypic selection in terms of accuracy and efficiency over three harvests. Models were developed throughout the harvests to evaluate their applicability in predicting genetic values in later harvests. For this purpose, 386 individuals of the breeding population obtained from crossings between 42 parents were evaluated. The population was evaluated in random block design, with six replicates over three harvests. The genetic effects of markers were predicted in the...

Jatropha-based biofuels have undergone a rapid boom-and-bust cycle in southern Africa. Despite strong initial support by governments, donors, and the private sector, there is a lack of empirical studies that compare the environmental and socioeconomic impacts of Jatropha’s two dominant modes of production: large plantations and smallholder-based projects. We apply a rapid ecosystem services assessment approach to understand the impact of two Jatropha projects that are still operational despite widespread project collapse across southern Africa: a smallholder-based project (BERL, Malawi) and a large plantation (Niqel, Mozambique). Our study focuses on changes in provisioning ecosystem services such as biofuel feedstock, food, and woodland products...

Multispectral and X-ray images for characterization of Jatropha curcas L. seed quality. Repositório Alice
BIANCHINI, V. de J. M.; MASCARIN, G. M.; SILVA, L. C. A. S.; ARTHUR, V.; CARSTENSEN, J. M.; BOELT, B.; SILVA, C. B. da.
Abstract: The use of non-destructive methods with less human interference is of great interest in agricultural industry and crop breeding. Modern imaging technologies enable the automatic visualization of multi-parameter for characterization of biological samples, reducing subjectivity and optimizing the analysis process. Furthermore, the combination of two or more imaging techniques has contributed to discovering new physicochemical tools and interpreting datasets in real time. We present a new method for automatic characterization of seed quality based on the combination of multispectral and X-ray imaging technologies. We proposed an approach using X-ray images to investigate internal tissues because seed surface profile can be negatively affected, but...

Over-expression of CYP78A98, a cytochrome P450 gene from Jatropha curcas L., increases seed size of transgenic tobacco Electron. J. Biotechnol.
Tian,Yinshuai; Zhang,Min; Hu,Xiaole; Wang,Linghui; Dai,Jiao; Xu,Ying; Chen,Fang.
Background: Jatropha curcas L. (further referred to as Jatropha), as a rapidly emerging biofuel crop, has attracted worldwide interest. However, Jatropha is still an undomesticated plant, the true potential of this shrub has not yet been fully realized. To explore the potential of Jatropha, breeding and domestication are needed. Seed size is one of the most important traits of seed yield and has been selected since the beginning of agriculture. Increasing the seed size is a main goal of Jatropha domestication for increasing the seed yield, but the genetic regulation of seed size in Jatropha has not been fully understood. Results: We cloned CYP78A98 gene from Jatropha,a homologue of CYP78A5 in Arabidopsis.Wefound that CYP78A98 was highly expressed in male...

Rampadarath,Sillma; Puchooa,Daneshwar; Bal,Subhasisa.
Background The classification of diversity in germplasm collections is important for plant breeding. The repetitive element palindromic-polymerase chain reaction (rep-PCR) technique was used to investigate inter-specific diversity within 17 species from the Euphorbiaceae family using REP and BOX primers. Results The agglomerative cluster analysis was used to evaluate the scoring data. BOX and REP gave amplification with polymorphism of 98.84% and 100% respectively. REP marker demarcated between the subgenus peltatae. Both markers confirmed Jatropha tanjorensis as a natural hybrid between Jatropha gossypifolia and Jatropha curcas. Five random sequences from the rep-PCR gels were chosen, cloned and sequenced. The blast results demonstrated that the amplified...

High oil prices, recent commitments by industrialized countries to enhance the use of renewable energy, and efforts by developing countries to stimulate foreign investment as a pathway to development have fueled high levels of interest in the biofuel sector throughout much of sub-Saharan Africa. Zambia is no exception. A large, land-locked country with high pump prices and vast tracts of land considered by many to be “degraded” or “underutilized,” investor interest in the sector has remained high despite uncertainties associated with unproven feedstocks and market fluctuations. While investment in multiple feedstock and production models may be observed, one of the primary investments has been in jatropha outgrower...

Wide genetic variability within and among families in a germplasm collection of jatropha curcas l. as revealed by microsatellite markers. Repositório Alice
FERNANDES, E. da C.; DIAS, L. A. dos S.; CAIXETA, E. T.; CORRÊA, T. R.; MUNIZ, D. R.; ALMEIDA, O. F. de.
J. curcas is a species with wide potential for biofuel production. However, there are few breeding programs and little information on its genetic structure. Studies indicate that the species has narrow genetic variability. We quantify genetic variability, and decomposing it within and among 28 families of a genebank by means of microsatellite markers. Thirty-nine pairs of primers were tested, of which six were polymorphic for a total of 18 alleles, with a mean of three alleles/locus. These six markers allowed genetic variability to be estimated within and among the families through estimates of PIC (0.36), expected (He=0.44) and observed (Ho=0.48) heterozygosity, inbreeding coefficient (f=-0.03), Shannon-Wiener index (H?=0.71), and the formation of 11...
