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.

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,...

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...

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...

Realidade e futuro do pinhão manso (Jatropha curcas L.) na produção sustentável de biodiesel no Vale do Paraíba/SP Ciências Agrárias
Ferreira, Willian J.; Batista, Getulio T..
A utilização mais eficiente de energia e a transição de fontes fósseis para alternativas energéticas renováveis têm sido propostas desafiadoras para o mundo atual. Cresce o número de pesquisas no setor dos biocombustíveis e existem motivações para a produção e uso do biodiesel. No Vale do Paraíba/SP, o pinhão manso tem despertado o interesse dos produtores rurais e seu plantio em áreas degradadas favorecerá o melhoramento das propriedades do solo e das condições ambientais. Ao criar cenários de otimismo à  cadeia produtiva do biodiesel a espécie se torna um importante elemento de sustentabilidade, fomentando o desenvolvimento da região.

Repetitive element palindromic PCR (rep-PCR) as a genetic tool to study interspecific diversity in Euphorbiaceae family Electron. J. Biotechnol.
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...

Respostas ecofisiológicas de plantas de Jatropha curcas L. irrigadas com água salina. Repositório Alice
FERREIRA, P. P. B.; NASCIMENTO, A. A. P. do; POMPELLI, M. F.; PINTO, J. M.; CHAVES, A. R. de M..
Com este trabalho objetivou-se estudar os efeitos da salinidade da água de irrigação sobre os parâmetros ecofisiológicos de plantas de Jatropha curcas L. com poda realizada em 438 dias após o transplantio. O experimento foi conduzido em área aberta com as plantas cultivadas em vasos de 200 L de capacidade de solo, utilizando-se um delineamento experimental em blocos ao acaso, com quatro repetições em esquema de parcelas subdivididas. Na parcela principal foram considerados os três acessos de J. curcas: JCAL171; CNPAE183 e CNPAE218 e nas subparcelas os quatro níveis de condutividade elétrica da água de irrigação (0,0 dS m-1; 2,5 dS m-1; 5,0 dS m-1 e 7,5 dSm-1). Em cada unidade experimental foram avaliadas aos 45 dias após a poda as variáveis de trocas...

The Local Social and Environmental Impacts of Smallholder-Based Biofuel Investments in Zambia Ecology and Society
German, Laura; Center for International Forestry Research; L.GERMAN@cgiar.org; Schoneveld, George C.; Center for International Forestry Research; G.Schoneveld@cgiar.org; Gumbo, Davison; Center for International Forestry Research; D.Gumbo@cgiar.org.
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...

Study on the effectmethod of soil moisture conservation method on yield of Jatropha, variety KUBP78-9 grown on Ultic Paleustalf, was carried out in order to compare the effect of no soil moisture conservation scheme (W1), plant residue mulch (W2), vetiver grass grown between Jatropha rows, slash and mulch (W3), and jack beanast cover crop (W4) on moisture changes within soil profile and yield of Jatropha. Drip irrigation at a rate of twolitres per plant was operated every two days during drought season (Dec 09-May 10). Results indicated that plant residue mulch tended to give the highest seed yield at 15% moisture content (200 kg rai-1) compared to the range of 130.9-145.3 kg rai-1 obtained from other treatments. Growing vetiver grass between rows of...
